Gabriel wants to solve the equation 5 eights M equals 25 what steps should he do to get him by itself on one side of the equation

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the Equation :

(5/8)m = 25

The first step to take with this kind of equation is to multiply both sides by the denominator, 8

5m/8 * 8 = 25 *8

5m = 200

Then, we can divide both sides by 5 in other to isolate m

5m / 5 = 200 / 5

m = 40

Answer: m+40

Step-by-step explanation:

Given the Equation :

(5/8)m = 25

The first step to take with this kind of equation is to multiply both sides by the denominator, 8

5m/8 * 8 = 25 *8

5m = 200

Then, we can divide both sides by 5 in other to isolate m

5m / 5 = 200 / 5

m = 40

Tell whether the angles are adjacent or vertical. Then find the value of x.
to
128°
The angles are
vertical
X=

Answers

Answer:

x = 128

Step-by-step explanation:

Adjacent angles - Angles right next to each other. They share a common vertex

Vertical angles - angles that are vertically aligned with each other.

The angle that has a measure of 128 degrees and x are vertical angles

If you didn't know vertical angles are congruent so because one angle equals 128 degrees the other equals 128 degrees

x = 128

The given angle are the vertical angles and the measure of the angle x is 128°.

Given that,
To specify whether the angles are adjacent or vertical. Then find the value of x.

What is the angle?

orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,
By the observation, angle x and 128° are the vertical angles and by the property of the intersection of the line both are equal angles so the measure of angle x is also equal to 128°.

Thus, the given angle is the vertical angle and the measure of the angle x is 128°.

what's the answer to
375 = 15c

Answers

Step-by-step explanation:

c = 375 / 15

c = 25

Hope it will help :)❤

25.

EXPLANATION:

The format 15c means 15 x c.

We know that the equation must equal 375.

So we can do 375 divided by 15 to find the missing value.

375/15 = 25.

We can check this by doing 25 x 15.

Adding 12 to the circle area is equal to the square area.

Or

Where

s = side of square

A = area of circle

So

s2 = 12 + 36

s2 = 48

Solve this for s to get the side length

How much air can the basketball
hold? With a radius of 3 inches. Round to the nearest hundredth.

Answers

Answer:

113.10 if you use the pi button

113.04 if you use 3.14

Step-by-step explanation:

We want to find the volume

V = 4/3  pi r^3

The radius is 3

V = 4/3 pi (3)^3

Using the pi button for pi

V = 113.09734

Rounding to the nearest hundredth

V = 113.10

If you use 3.14 for pi

V = 113.04

An easier way my mom taught me for tipping in restaurants is you look at the bill $31.15 in this case move the decimal to the left one place and that give you 10%..double it and you have your 20% tip.
