If you multiply a number by 3 and then subtract 5 you will get 40 what is the number

Answers

15 x 3 = 45 - 5 = 40
The number will be 15.
Hope this helped.

To find the answer the question first write it out. 3*x-5=40. move the five over next to the 40 and cancel out -5. so the new equation looks like this. Then add 40+5 which is 45.Lastly you have the number 3 and the variable x. now you have to divide 3 by 45 to get your final answer 15. so x=15.

3*x=40+5

3*x=45

A bottle of soft drink is two thirds full. Jack drinks one quarter of the remaining soft drink. How full is the bottle now

Answers

Charli,

First find what 1/4 of 2/3 is.

1/4 of 2/3 = 1/6

(That is 1/4 times 2/3 = 1/6)

So, the bottle was 2/3 full, it is now ...

2/3 - 1/6

=4/6 - 1/6

= 3/6 or 1/2 full.

We know that the bottle of soft drink has a remaining volume which is 2 / 3 of the original.

Since Jack drank 1 / 4 of the remaining volume, hence only 3 / 4 now finally remains, the total is:

(2 / 3) * (3 / 4) = 6 / 12 = 1 / 2

Hence the bottle is now one half full

Rectangle EFGH is translated according to the rule T -5,9(x,y). If the coordinates of the pre-image of point H are(-2,-3) what are the coordinates of H’

Answers

The new coordinates of H would be (-7,6).

Answer: The co-ordinates of the image H' are (-7, 6).

Step-by-step explanation: Given that the rectangle EFGH is translated according to the following rule :

[tex]T_{-5,9}(x,y).[/tex]

We are to find the co-ordinates of the image H' if the co-ordinates of the pre-image H are (-2, -3).

We know that

[tex]T_{h,k}(x,y)=(x+h,y+k).[/tex]

For the given information, we have

(h, k) = (-5, 9) ⇒ h = -5 and k = 9.

Therefore, we get

[tex]T_{-5,9}(-2,-3)=(-2-5,-3+9)=(-7,6).[/tex]

Thus, the co-ordinates of the image H' are (-7, 6).

The answer would be, B MN\MO HOPE IT HELPS

The option that represents cos M is MN / MO

Using trigonometric ratios, we can find the ratio of sides of a right angle triangle.

Trigonometric ratios:sin x = opposite / hypotenusecos x = adjacent / hypotenusetan x = opposite / adjacent

Therefore,

cos M = adjacent / hypotenuse

cos M = MN / 0M

Therefore, cos M = MN / MO

One day a store sold 20 sweatshirts. White ones cost $ 10.95 and yellow ones cost $ 13.50. In all, $262.35 worth of sweatshirts were sold. How many of each color were sold?

Answers

17 yellow sweatshirts were sold and 3 white sweatshirts were sold.

How did I get this?

First, we need to figure out what we know.
20 sweatshirts sold
White sweatshirts $10.95
Yellow sweatshirts $13.50
Total spent $262.35

$10.95W + $13.50Y = $262.35
W + Y = 20 sweatshirts

In both equations, the variables represent the amount of sweatshirts sold, which is unknown, but when we know the amount it will add up to $262.35.

Y = 20 - W so lets substitute that into the first equation

10.95w + 13.50(20 - W) = 262.35
Distribute the 13.50 into the parenthesis.

10.95w + 270 - 13.50w = 262.35
Combine like terms.

-2.55w + 270 = 262.35
Subtract both sides by 270, the left side will cancel out.

-2.55w = -7.65
Divide -2.55 by both sides to isolate the variable.

W = -7.65/-2.55
(W)hite = 3 sweatshirts

Put 3 sweatshirts into our second equations.

Y = 20 - 3
(Y)ellow = 17 sweatshirts

So, 17 yellow sweatshirts were sold and 3 white sweatshirts were sold.

Now, lets check our math by substituting the # of sweatshirts into our first equation.

$10.95(3) + $13.50(17) = $262.35
$32.85 + $229.50 = $262.35
$262.35 = $262.35 (correct!)

The 6 members of the homecoming decorating committee want to make 525 paper flowers for the homecoming dance. Each flower takes about 412 minutes to make. About how long will each member of the committee have to spend making flowers?

Answers

Answer:

About 7 hours per person

Step-by-step explanation:

412 divided by 60 because there are 60 minutes in an hour.

6.8667 which is about 7 hours.

The each member will take 7 hours.

What is Unitary method?

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value

Given:

total member = 6 member

Each flower take = 412 minutes

we know

1 hour= 60 minutes

So, each member will have

=412/60

=6.866

=7 hours

Hence, each member will work for 7 hours

Since it's 2x+1 when x>1 (greater than 1) and x² when x≤1 (less than or equal to 1), we can notice that 0 is less than 1 and not greater than 1. Therefore, we plug it into x² to get 0²=0 for f(0). To graph this, it's pretty simple. Simply graph both functions, but when x=1 for x² simply erase everything to the right of it. For 2x+1, do the same thing but for x=1 (1, 3) simply erase everything to the left of it. In addition, since it doesn't have a x=1 value (since it has to be greater than 1), we put a open circle in at (1, 3)

What is the solution to the equation?

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Sam and Chad are ticket-sellers at their class play. Sam is selling student tickets for $2.00 each, and Chad selling adult tickets for $5.50 each. if their total income for 24 tickets was $83.00.

Let x be the number of tickets sold to students and y be the number of tickets sold to adults. Then the equation is given as,

x + y = 24 ...1

2x + 5.5y = 83 ...2

From equations 1 and 2, then we have

2(24 - y) + 5.5y = 83

48 - 2y + 5.5y = 83

3.5y = 35

y = 10

Then the value of x will be given as,

x + 10 = 24

x = 24 - 10

x = 14

The number of tickets sold to students by Sam will be 14.

FOR 10 POINTS WILL MARK BRAINLIEST It costs $175 to rent a jet ski for 2 hours. It costs $300 to rent a jet ski for 2 hours. It costs 300$ to rent a jet ski for 4 hours. Write an equation that represents the cost y (in dollars) of renting a jet ski for x hours

Answers

y=$175+x I think this is it? one half of 175 is 87.5 so you know.

Final answer:

The equation that represents the cost y (in dollars) of renting a jet ski for x hours is y = -87.50x + 525.

Explanation:

The equation that represents the cost y (in dollars) of renting a jet ski for x hours can be found by analyzing the given information. Let's break it down step by step:

We are given that it costs $175 to rent a jet ski for 2 hours. This means the cost per hour is $175 / 2 = $87.50.We are also given that it costs $300 to rent a jet ski for 4 hours. This means the cost per hour is $300 / 4 = $75.Based on these two data points, we can see that as the number of hours increases, the cost per hour decreases. Therefore, we can infer that the cost of renting a jet ski is a linear function of the number of hours.Now, let's use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
In this case, we can use the point (2, 175) and the slope -87.50 to write the equation:
y - 175 = -87.50(x - 2)Simplifying the equation:
y - 175 = -87.50x + 175
y = -87.50x + 350 + 175
y = -87.50x + 525

Therefore, the equation that represents the cost y (in dollars) of renting a jet ski for x hours is y = -87.50x + 525.
