Answer:
$70.77
Step-by-step explanation:
Let represents the total cost. We know for our problem that each yard of satin fabric costs $8.09, so yards will cost . similarly, each yard of cotton fabric costs $3.79, so yards will cost . We can also infer that the total cost, , will be the sum of the yards of satin fabric and the yards of cotton fabric, so:
Now, to determine the amount that Angeline would spend in all if she bought 5 yards of satin fabric and 8 yards of cotton fabric, we just need to replace and in our expression:
We can conclude that if Angeline would spend in all if she bought 5 yards of satin fabric and 8 yards of cotton fabric, she would spend $70.77

Answer: Choice D) ordered pair is not a solution to the second equation
We can see this by replacing x and y with 1 and -4 respectively
2x + y = 4
2*1 + y = 4 .... replace x with 1
2*1 + (-4) = 4 ... replace y with -4
2 - 4 = 4
-2 = 4 .... this equation is false because -2 and 4 are different values
The last equation being false means that the original equation 2x+y = 4 is also false when (x,y) = (1,-4). Therefore, this ordered pair is not a solution to the second equation 2x+y = 4
A solution to the system must make BOTH equations true simultaneously, not just one.
Answer:
D
Step-by-step explanation:
2x + y = 4
If you substitute x = 1, and y = -4, then
2(1) - 4 = 2 - 4 = -2 not 4
Solve using substitution
y=3x-5
2x+5y=-42
Answer:
Solution point is (-1,-9)
Step-by-step explanation:
Put the value of y in the first equation into the second equation.
2x + 5(3x - 5) = - 42 Remove the brackets on the left2x + 15x - 25 = - 42 Combine like terms on the left17x - 25 = - 42 Add 25 to both sides17x - 25 + 25 = - 42 + 25 Do the addition17x = - 17 Divide by 1717x/17 = -17/17 Do the divisionx = - 1=======
Solve for y
y = 3x - 6x = -1y = 3(-1) - 6y = -3 - 6y = - 9which of the following shows the algebraic solution and the graphical solution of the inequality 6d - 7 > 11

Transformation that produces an image that is the same shape but different size?
Answer:
Transformation that produces an image that is the same shape but different size is known as Dilation.
Step-by-step explanation:
There are many types of translations.
1. Rotation
2. Reflection
3. Translation
4. Dilation
We know that rotation, reflection and translation are rigid transformation. It means these transformation can not effect the size of the preimage.
Dilation represents the enlargement and compression of the figure according to the scale factor k.
If |k|>1, then it represent enlargement and if |k|<1, then it represent compression.
Therefore the transformation that produces an image that is the same shape but different size is known as Dilation.

Jason combined 1 1/4 ounces of strawberry preserve from a jar with 7/8 of an ounce of strawberry preserve as a part of individual dessert bowls.
Jason plans on using 1/5 of an ounce of strawberry preserve in each dessert bowl. How many dessert bowls can he completely fill?
Answer: 10 dessert bowls.
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. Rewrite 1 1/4 ounces as a fraction:
[tex](4+1)/4=\frac{5}{4}[/tex]
2. You must add 5/4 ounces of strawberry preserve and 7/8 ounce of strawberry preserve, as following:

8(x + 1) - 3(x + 4) = 7(2 - x)
Can someone help me find the value of x?
Answer:
x=71
Step-by-step explanation:
Since this is an isosceles triangle the bottom 2 angles are equal.
The three angles of the triangle are x, x, and 38. They must add to 180 degrees
x+x+38 = 180
Combine like terms
2x+38=180
Subtract 38 from each side
2x+38-38 = 180-38
2x = 142
Divide each side by 2
2x/2 =142/2
x =71
Patrick saved $500. He received 25% of the money for his birthday, saved 30% of the remainder for his allowance, and earned the rest of it by mowing laws. How much of his savings did he earn by mowing laws?
Answer:
Patrick earned $262.50 by mowing lawns
Step-by-step explanation:
500*0.75=375
375*.7=262.5
Answer:
$262.50
Step-by-step explanation:
It is a poorly worded question.
25 Percent of the 500 was from his birthday money.
500 * .25 = 125
That leaves 500-125 = 375
He saved 30 % of the 375 from his allowance
375 * .3 =112.50
375-112.50 =262.50
The rest is from mowing lawns.

Kate uses 2 packets of milk powder per day how many days will 1/3 of a packet of milk powder last.
To find out how many days 1/3 of a packet of milk powder will last, divide 1/3 by 2 to get 1/6 of a day.
Explanation:To find out how many days 1/3 of a packet of milk powder will last, we can use the information given. Kate uses 2 packets of milk powder per day. This means in one day, she uses 2 packets. So, in order to calculate how many days 1/3 of a packet will last, we need to divide 1/3 by 2. This gives us 1/6.
Therefore, 1/3 of a packet will last 1/6 of a day.

1/3 of a packet of milk powder will last 1/6 of a day, or 4 hours, for Kate who uses 2 packets of milk powder per day.
If Kate uses 2 packets of milk powder per day, to determine how many days 1/3 of a packet of milk powder will last, you can perform a simple division. Since she uses 2 packets per day, you would divide the amount she has, 1/3 of a packet, by her daily usage, which is 2 packets. Therefore:
1/3 packets / (2 packets/day) = (1/3) / 2 days = 1/6 days
Thus, 1/3 of a packet of milk powder would last for 1/6 of a day. To determine the number of hours this represents, you can multiply 1/6 of a day by the number of hours in a day:
(1/6 day) times (24 hours/day) = 4 hours
Therefore, 1/3 of a packet of milk powder will last for 4 hours based on her current usage.

Step-by-step explanation:
It is worked out that 3 ladles full of soup each will feed 160 people.
The customers have complained in the past that the portions are too small.
The cook decides to give 5 ladles full of soup to each person.
How many people can now be fed soup?
Answer:if your still on it tell me
Step-by-step explanation:
By using the ratio and proportion method, it is calculated that 5 ladles of soup can feed 96 people.
Explanation:This problem can be solved using the ratio and proportion concept in Mathematics. Given that 3 ladles of soup feed 160 people, we can set up the ratio 3 ladles : 160 people. If the cook now provides 5 ladles, we need to know how many people this amount can feed. To find this, we cross-multiply in the ratio.
Calculating: (3 ladles x X people) = (160 people x 5 ladles), after simplifying we find that X = 96 people. This calculation suggests that the soup will now feed 96 people if each person is given 5 ladles of soup.

Paul took 42 mile bicycle trip. he bicycle 1 1/2 hours in the morning and two hours in the afternoon what is his average speed in miles per hour
Answer:
Paul's average speed for his bicycle trip is 12 miles/hour.
Step-by-step explanation:
Since Paul rode a total of 42 miles, we need to add up the total time it took him to complete all 42 miles. Since her rode 1.5 hours in the morning and another 2 hours in the afternoon, he rode a total of 3.5 hours. Speed is calculated by dividing distance by time. Since his total distance is 42 and his total time is 3.5, we divide 42 by 3.5 to get 12. Since our calculations included miles and hours, then our final answer would be 12 miles per hour.

Suppose we want to choose
2 letters, without replacement, from the
4 letters A, B, C, and D.
If order matters, then there are 12 ways to do this
If order does not matter, then there are 6 ways to do this
===========================================
We have 4 choices for the first slot and 3 choices for the next (we can't reuse a letter) so that's where 4*3 = 12 comes from
If order doesn't matter, then something like AB is the same as BA. So we are doubly counting each possible combo. To fix this, we divide by 2: 12/2 = 6
To be more formal, you can use nPr and nCr to get 12 and 6 respectively (use n = 4 and r = 2)
In combinatorics, you can choose 2 letters from 4 (A, B, C, D) without replacement in 6 ways, according to the 'combination' principle in probability.
Explanation:The subject of this question is combinatorics, a topic in Mathematics, particularly probability. You are asked to choose 2 letters without replacement from a set of 4 different letters {A, B, C, D}. To do this, we can use the formula for combinations, which is denoted as nCr, where n is the total number and r is the number being chosen. In this case, we can see it as 4C2.
To execute this, the formula is ‘n! / [r!(n-r)!]’ where '!' denotes factorial, meaning you multiply all natural number up to that number. Hence, 4C2 = 4! / [2!(4-2)!]. Factorial 4 (4!) = 4 * 3 * 2 *1 = 24. Factorial 2 (2!) is simply 2 * 1 = 2. Thus the calculation becomes 24 / [2*(2!)], simplifying to 24 / 4 which equals 6. So, there are 6 ways to choose 2 letters from 4 without replacement.
