A classroom's length is 3m less than two times its width. The classroom has a length of 9m. Solve an equation to determine the width of the classroom.

Answers

The equation would be 2w-3=9. Do the inverse operation for '3' on both sides of the equation. Then do the inverse operation on both sides of the equation for '2w'.

Surface area and volume of trapezoid prim

Answers

Surface Area formula of a prism:
S.A = 2 × Area of base + Perimeter of Base × Height of prism

Area of base ( trapezium ) = $(1)/(2)$ × height (base₁ + base₂)
Perimeter of base ( trapezium ) = All sides added together (a₁ + a₂ + b₁ + b₂)

Volume Formula of prism:
V = Area of base × Height of prism

And just substitute them all

You buy a game for $40, and the sales tax is $2. What percent of the game price are you paying in sales tax?4%

5%

8%

20%

Answers

You can write this as 2/40. 2 is the sales tax and 40 is the total price. First, find the decimal. Divide the numerator by the denominator to get the decimal. You will get 0.05. Now, multiply the decimal by 100 to get the percent or just move the decimal two places to the right. The final answer is 5%

If Colorado Springs, Colorado, has 1.4 times more days of sunshine than Boston, Massachusetts, how many days of sunshine does each city have if there are a total of 475 days of sunshine between the two in a year?

Answers

Suppose, number of sunshine days in Boston, Massachusetts is: x

Then, number of sunshine days in Colorado Spring, Colorado will be: 1.4 x

Given that, total number of days of sunshine for both city is: 475

That is, x+1.4x = 475

Solving for x,

x=198

1.4x= 277

Therefore,

Number of sunshine days in Boston, Massachusetts is 198

and

Number of sunshine days in Colorado Spring, Colorado is 277

Plz help i really don't understand these two Q please help by showing me step by step ;-; im so sorry

Answers

Q1:
make y the subject for both equations
2x - y = 10, y = 2x - 10
x + y = 2, y = 2 - x
therefore
2 - x = 2x - 10
2 + 10 = 2x + x
12 = 3x
4 = x

Q2:
Sub x into an equation to find y
x + y = 2
y = 2 - x
y = 2 - 4
y = -2

Answers

A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled.

So the answer would be C

But lets see the proof:
The first x and y ratio is 2:6 which equals 1:3
The second one is 4:12 which equals 1:3
The third one is 6: 18 which equals 1:3
The fourth one is 8: 24 which equals 1:3

Which means all 4 of the ratios are the same. So therefore the answer is C

A proportional relationship meaning that all the sets are proportional.

A) 2/6 = 0.33
5/8 = 0.625

So, A is a wrong answer.

C) 8/4 = 2
24/4 = 6

4/12 = 2/6
6/18 = 2/6

Therefore, we have a proportional relationship!

Answer:- C.
