Answer:

D

18y = 306

y = 25 - x

Step-by-step explanation:

y is the number of 18-inch containers.

1 18-inch container occupies 18 inches

y number of 18-inch containers occupy 18y inches.

We are told that  the 18-inch containers occupy 306 inches.

The gives us one equation:

18y = 306    Equation 1

There are 25 containers altogether. x number of them are 12 inches. y number of them are 18 inches. This give us the second equation.

x + y = 25

Now we solve the second equation for y.

y = 25 - x    Equation 2

Put Equations 1 and 2 together, and you have a system of equations.

18y = 306

y = 25 - x

Answer:

D

18y = 306

y = 25 - x

Simplify the following expressing. Show your work and explain each step. <br><br> 7-(5-3(2+6(2^2)))
Anon25 [30]

Answer:

80

Step-by-step explanation:

7-(5-3(2+6(2^2)))

When a question has multiple signs, the rule of BODMAS is used. That is, Bracket Of Division Multiplication Addition and Subtraction. The question above will therefore be solved in that order.

The first bracket, we have 2^2

That gives 4

Rewriting the question will give

7-(5-3(2+6(4)))

The question in the next bracket will follow

(2+6(4))

In this bracket too, we have the plus sign and the multiplication sign, so the multiplication will first be solved, them addition will follow.

(2+24)

(26)

Rewriting the question again, we have

7-(5-3(26))

And then, we have the last bracket

(5-3(26))

But we have both the Subtraction sign and the Multiplication sign in this bracket also, so the multiplication will first be solved, before the Subtraction.

(5-3(26))

(5-78)

(-73)

And lastly we have

7-(-73)

7+73

80

Answer:

1. Below 2. B. d = 8h

Step-by-step explanation:

The graph is a bit confusing. But basically, substitute x for the numbers they give you.

5x

5 · 1 = 5 = y

5 · 2 = 10 = y

5 · 3 = 15 = y

5 · 4 = 20 = y

7x

7 · 1 = 7 = y

7 · 2 = 14 = y

7 · 3 = 21 = y

7 · 4 = 28 = y
