30( \frac{1}{2} x - 2) + 40( \frac{3}{4} y - 4) =  \\

(30 \times  \frac{1}{2} x) -( 30 \times 2 )+ (40 \times  \frac{3}{4} y )- (40 \times 4 )=  \\

15x - 60 + 30y - 160 =  \\

15x + 30y - 220

agasfer [191]
Hi!

The answer is :
32.15 = (3 x 10) + (2 x 1) + (1/10) + (5/100)

That's 32.15 in expanded fraction.

Hope it helps and have a wonderful day!

A 100-gallon fish tank fills at a rate of x gallons per minute. The function is F(x)=100/x. if the tank has been filling for 20
mixer [17]
The second graph is correct.

There will be a vertical asymptote at x=0, since we cannot divide by 0.  Using the x-axis on the second graph, if we substitute 5 in for x, we have 100/5+20 = 20+20=40.  There is a point on this graph here.  Using 10 for x, we have 100/10+20 = 10+20 = 30.  There is a point on the graph here.  Every point matches.

Which of these equations have no solution? check all that apply
finlep [7]

Answer:

A, B, and E

Step-by-step explanation:

Let's look through each of the answer choices.

A) 2(x + 2) + 2 = 2(x + 3) + 1

Simplify this by expanding out the parentheses:

2x + 2 * 2 + 2 = 2x + 2 * 3 + 1

2x + 4 + 2 = 2x + 6 + 1

2x + 6 = 2x + 7

6 = 7

Well, we know that 6 is NOT equal to 7, so this has no solutions.

B) 2x + 3(x + 5) = 5(x – 3)

Simplify this by expanding out the parentheses:

2x + 3x + 3 * 5 = 5x - 5 * 3

5x + 15 = 5x - 15

15 = -15

Again, we know that 15 is NOT equal to -15, so this also has no solutions.

C) 4(x + 3) = x + 12

Simplify this by expanding out the parentheses:

4x + 4 * 3 = x + 12

4x + 12 = x + 12

3x = 0

x = 0

This actually does have a solution when x = 0, so eliminate this.

D) 4 – (2x + 5) = (–4x – 2)

Simplify this by expanding out the parentheses:

4 - 2x - 5 = -4 - 2

-2x - 1 = -6

-2x = -5

x = 2.5

This also has a solution when x = 2.5, so eliminate this.

E) 5(x + 4) – x = 4(x + 5) – 1

Simplify this by expanding out the parentheses:

5x + 5 * 4 - x = 4x + 4 * 5 - 1

4x + 20 = 4x + 19

20 = 19

Here, we know that 20 is NOT equal to 19, so this has no solution.

Hope this helps!
