Answer:
Harry is 2 years old and Jim is 6 years old.
Step-by-step explanation:
set up the equations. let harry be h and jim be j.
h+4=j
j+2=2(h+2)
plug in the j from the first equation.
you should get h=2 (harry is two years old)
if h+4=j, 2+4=j. so j=6 (jim is six years old)
Answer:
Harry is 2 years old and Jim is 6 years old.
Step-by-step explanation:
Let x years be Harry's age now and y years be Jim's age now.
1. In 4 years, Harry’s age will be x+4 years. If in 4 years, Harry’s age will be the same as Jim’s age is now, then
[tex]x+4=y.[/tex]
2. In 2 years, Jim's age will be y+2 years and Harry's age will be x+2 years. If in 2 years, Jim will be twice as old as Harry will be, then
[tex]y+2=2(x+2).[/tex]
Solve the system of two equations:
[tex]\begin{array}{l}x+4=y\\y+2=2(x+2).\end{array}[/tex]
Substitute y=x+4 into the second equation:
[tex]x+4+2=2(x+2),\\ \\x+6=2x+4,\\ \\6-4=2x-x,\\ \\x=2[/tex]
and [tex]y=2+4=6.[/tex]

A storeowner orders 25 calculators that cost $48 each. The storeowner can sell each calculator for $60. The storeowner sold 22 calculators to customers. He had to return 3 calculators that were never sold and pay a $2 charge for each returned calculator (although the initial cost is refunded). What is the storeowner's profit?
25*48=1,200
So we start at -1,200
22*60=1,320
So currently we are at a profit of $120.
120-6=114
Total profit: $114
As per the given values, the storeowner's profit is $114.
Explanation:Total number of calculators = 25
Cost of calculators = $48
The amount at which they can be sold = $60.
To calculate the storeowner's profit, we need to consider the total cost and total revenue.

there are 11 regular players and 5 substitute players on a soccer team how many players are on 15 soccer teams ??
Answer:
225 players (including the substitutes)
Step-by-step explanation:
11 regular player and 4 substitutes makes 15 team members per team.
15 players on each team times 15 teams gives you 225 players in total.
The total number of players on 15 soccer teams can be calculated by multiplying the total number of players (including regular and substitute) on one team (16 players) by the number of teams (15), which equals 240 players.
Explanation:The subject of this question is Mathematics, and it's referencing a concept of multiplication in a real-world context. To determine the total number of players on 15 soccer teams, you consider that each team is composed of 11 regular players and 5 substitutes. So, the total number of players on one team is 16 (11 regular players + 5 substitutes).
To find out the number of players on 15 teams, you multiply the number of players on one team by 15. That is, 16 players * 15 teams = 240 players. So, there are 240 players on 15 soccer teams.

The figure shows five points. A point has been translated right and up
A point has been translated right and up from point D could be the image of B.
It indicates that a point was translated right and up.
As a result, any point existing on the rightmost side cannot be the translated point.
As a result, points E and D are ruled out.
There is no point that is higher than point A.
As a result, no "up" translation is available for point A.
Only points C and B are capable of "right and up" movement.
As a result, the first option "Point D could be the image of B" is correct.
Which value is the same as 2 tenths?
2 tenths is equal to 0.2 in decimal format. This is derived from its fraction format, 2/10, and its place value in the base-ten number system, which is a 'tenths' place.
Explanation:In mathematics, the value that is equivalent to 2 tenths is 0.2. This is because when we say 'tenths', we are referring to a fractional or decimal value that has a denominator of ten in the context of fractions or one place after the decimal point.
Therefore, 2 tenths is essentially 2 divided by 10 which equals 0.2 in decimal format. We can further illustrate this using a base-ten number system. In this system, each place to the right of the decimal point represents a 'tenths' place value. Therefore, in the number 0.2, the digit '2' is in the 'tenths' place.

Dan wants to make 12 pancakes but what quantity of each ingredient should he use for 240g plain flour,2 eggs and 600ml milk?
To make 12 pancakes, Dan should use 20g of plain flour, 2 eggs, and 50ml of milk.
Explanation:To determine the quantity of each ingredient needed to make 12 pancakes, we can use the ratio of ingredients given in the recipe:
240g plain flour : 2 eggs : 600ml milk
To find the quantity of plain flour needed for 12 pancakes, we can set up a proportion:
240g / x = 12 / 1
Cross multiplying, we get:
x = (240g * 1) / 12
x = 20g
Therefore, Dan should use 20g of plain flour for 12 pancakes. Similarly, he should use 2 eggs and 50ml of milk for 12 pancakes.

Julia is allowed to watch no more than 5 hours of telivison a week. So far this week, she has watched 1.5 hours. write and solve an inequality to show how many hours of teli she can watch this week. ( can u show your work along with it? )
Answer:
she can watch 3.5 hours this week.
Step-by-step explanation:
Julia is allowed to watch no more than 5 hours of television a week.
Let x be the number of hours she can watch per week
number of hours not more than 5 hours
so x<=5
She already watched 1.5 hours. so inequality becomes
x+ 1.5 <= 5
Now we solve for x
subtract 1.5 on both sides
x + 1.5 < = 5 - 1.5
x < = 3.5
So, she can watch 3.5 hours this week.

Write the expression 6a-2(a-1) in simplest form
Final answer:
To simplify the expression 6a - 2(a - 1), distribute the -2 across the terms inside the parentheses, and then combine like terms to get the simplest form, which is 4a + 2.
Explanation:
To simplify the expression 6a - 2(a - 1), you need to distribute the -2 across the terms inside the parentheses and then combine like terms. Here's the process step by step:
Distribute the -2 to both a and -1 inside the parentheses: -2 x a gives us -2a, and -2 x -1 gives us +2.Write out the new expression without parentheses: 6a - 2a + 2.Combine like terms by subtracting -2a from 6a, which results in 4a.Add the constant term 2 to get the final simplified expression: 4a + 2.The simplest form of the expression is 4a + 2.

The answer is A. g(x).
Here's why:
f(x) = -x^4 - 2: This function is a downward-facing parabola (due to the negative coefficient of x^4) with a maximum y-value at its vertex. The vertex occurs at x = 0, and the maximum y-value is f(0) = -2.
g(x) = -3x^3 + 2: This function is a cubic function with a local maximum, but it does not have a global maximum. However, its maximum value is still greater than the maximum value of f(x).
Key points:
The maximum y-value of f(x) is limited to -2 because of the negative leading coefficient and the constant term of -2.
g(x) doesn't have a defined maximum y-value, but it can reach values greater than -2, making its maximum value larger than that of f(x).
Therefore, g(x) has the largest maximum y-value among the two functions.

Which equation is a point slope form equation for line AB?
a) y−2=−2(x+6)
b) y−2=−2(x+2)
c) y−6=−2(x+2)
d) y−2=2(x+2)
Answer:
the answer is c
Step-by-step explanation:
Answer:
c) y−6=−2(x+2)
Step-by-step explanation:
The general point slope form equation is:
y - y1 = m*(x - x1)
where x and y are the variables, (x1, y1) is the coordinate of a point on the line and m is the slope of the line.
To calculate the slope of the line we need two points on the line (x1, y1) and (x2, y2) and the following equation:
m = (y2 - y1)/(x2- x1)
Coordinates of point A: (-2, 6)
Coordinates of point B: (2, -2)
Replacing into the equation:
m = (6 - (-2))/(-2 - 2)
m = 8/(-4)
m = -2
Replacing this value and coordinate of point A into the general point slope equation we get:
y - 6 = -2*(x - (-2))
y - 6 = -2*(x + 2)

A recipe calls for 40 ounces of meat.How many pounds of meat does the recipe require?
Answer: 40 ounces=2.5 pounds
Step-by-step explanation:
Since 1 pound=16 ounces. You have to see how many times 16 goes into 40, it goes in forty 2 times with 8 left over so that means we need decimal, since 8 is half of 16 the answer is 2.5.
Final answer:
To convert 40 ounces of meat to pounds, divide by the unit equivalence of 16 ounces per pound, resulting in 2.5 pounds of meat needed for the recipe.
Explanation:
The student is asking how many pounds are equivalent to 40 ounces of meat. To find the answer, you will need to know the unit equivalence between ounces and pounds.
The unit equivalence is 1 pound = 16 ounces. Therefore, to convert ounces to pounds, you divide the number of ounces by the unit equivalence.
Converting 40 ounces to pounds:
Start with the given amount in ounces: 40 ounces.Use the unit equivalence: 1 pound = 16 ounces.Divide 40 ounces by 16 ounces per pound to find the number of pounds.40 ounces ÷ 16 ounces/pound = 2.5 pounds
So, the recipe requires 2.5 pounds of meat.
