3 0

Answer:

Step-by-step explanation:

Notice that 27 can be factored out as 3 * 3 * 3

and 12 can be factored out as: 2 * 2 * 3

then when we study the ratio 27/12, we can cancel out a factor 3, leaving us with: (3 * 3) / (2 * 2) = 9 / 4

Then 9 is the number you need to type in the box.

Solve for x. 13 =(5x+ 6)/8 + (5x+4)/4

valkas [14]

Answer: x=6

Step-by-step explanation:

To solve for x, we want to isolate the variable.

$\frac{5x+6}{8} +\frac{5x+4}{4} =13$ [get common denominator]

$\frac{5x+6}{8} +\frac{2(5x+4)}{8} =13$ [add fractions]

$\frac{5x+6+10x+8}{y} =13$ [combine like terms]

$\frac{15x+14}{8} =13$ [multiply both sides by 8]

$15x+14=104$ [subtract both sides by 14]

$15x=90\\$ [divide both sides by 15]

$x=6$

Now, we know that x=6.

25-foot wire connects the top of a utility pole to a point on the ground located 7 feet away from the base of the pole.

marta [7]

Answer:

B. 24 ft.

Step-by-step explanation:

25 would be the hypotenuse of a triangle and 7 is a leg, so

7^2 + x^2 = 25^2

49 + x^2 = 625

x^2 = 576

x = 24 ft
