The equation 7(u-5)=21 is solved in several steps below. For each step, choose the reason that best justifies it.

krok68 [10]

Answer:

$u = 8$

Step-by-step explanation:

The steps are not shown. So, I will solve from scratch

Given

$7(u -5) = 21$

Required

Solve, with steps

$7(u -5) = 21$

Apply distributive property

$7u - 7 * 5 =21$

$7u - 35 =21$

Collect like terms

$7u = 35 + 21$

$7u = 56$

Divide both sides by 7

$\frac{7u}{7} = \frac{56}{7}$

$u = 8$

You could do any number:
(8•100/9•100)=(800/900)

What is the relative size of (how many times as large) a circle's' circumference C to its diameter, d

Pavlova-9 [17]

Answer:

The circumference is pi times larger than the diameter of a circle.

Step-by-step explanation:

The formula of the circumference of a circle is

C = 2(pi)r = (pi)d

C = (pi)d

To find the ratio of the circumference to the diameter, divide both sides of the equation by d.

C/d = pi

The circumference is pi times larger than the diameter of a circle.
