Answer:

$x=\frac{11}{c}$

Step-by-step explanation:

We have been given the equation $cx-4=7$

We have to eliminate 4 from the left hand side of the equation. Since, 4 is in subtraction hence, add 4 to both sides to eliminate 4.

$cx-4+4=7+4\\\\cx=11$

Now, we have to eliminate c. Since, c is in multiplication with x hence, divide both sides by c

$\frac{cx}{c}=\frac{11}{c}\\\\x=\frac{11}{c}$

Therefore, the value of x is $x=\frac{11}{c}$

You and your friend collect 180 cans for a food drive. The ratio of cans you collected to cans your friend collected is 4 to 5.

marissa [1.9K]

Are you looking for the number of cans you and your friend each collected? If yes, here is the solution:

Let x be the number of cans.

4x + 5x = 180
9x = 180
9x/9 = 180/9 (divide both sides of the equation by 9)
x = 20

Now, substitute the values:
4(20) + 5(20) = 180
80 + 100 = 180
180 = 180

Therefore, you collected 80 cans and your friend collected 100 cans.

It took Aiden 6 hours to plant 8 trees. How many hours would it take for him to plant 20 trees? 24, 18, 23, 15

Pepsi [2]

<h3>Answer: 15 hours (choice D)</h3>

================================================

Work Shown:

(6 hours)/(8 trees) = (x hours)/(20 trees)

6/8 = x/20

6*20 = 8*x ... cross multiply

120 = 8x

8x = 120

x = 120/8

x = 15

It takes him 15 hours to plant 20 trees.

A ) $\sqrt[4]{ x^{3} } = x^{3/4}$
B ) $\frac{1}{ x^{-1} } = x$
C ) $\sqrt[10]{ x^{5} * x^{4}* x^{2} } = \sqrt[10]{ x^{11} }= x^{11/10}$
D ) $x^{1/3} * x^{1/3} * x^{1/3} = x$
Therefore: B = D
