Answer:

The value of x is 1 after solving the linear equation.

Step-by-step explanation:

Given equation is:

\frac{1}{5}(10x-20)=x-3

We will solve the equation by simplifying first.

\frac{1}{5}*10x-\frac{1}{5}*{20}=x-3\\2x-4=x-3

Now, we will subtract x from both sides of the equation,

2x-x-4 = x-x-3

x-4 = -3

Next, we will add 4 on the both sides of the equation,

x-4+4 = -3+4

x = 1

Hence,

The value of x is 1 after solving the linear equation.

∠A and ∠B are vertical angles. If m ∠A=(2x+26)∘ and ∠B=(3x−29)∘, then find the measure of ∠A.
Leya [2.2K]

The measure of angle (m ∠A) is 136°

<h3>Vertical angles theorem</h3>

From the question, we are to find the measure of angle A

From the given information, we have that

∠A and ∠B are vertical angles

Thus

∠A = ∠B

and

Also, from the given information,

m ∠A=(2x+26)°

and

m ∠B= (3x−29)°

∴ (2x+26)° = (3x−29)°

Now, solve for x

2x + 26 = 3x - 29

26 + 29 = 3x - 2x

55 = x

∴ x = 55

But measure of angle A is given by

m ∠A=(2x+26)°

Put the value of x into the equation,

m ∠A=(2(55)+26)°

m ∠A=(110+26)°

m ∠A = 136°

Hence, the measure of angle (m ∠A) is 136°

A scale on a map shows that 1 inch = 25 miles. How many inches on the map represent 100 miles? *
Lilit [14]

Answer:

4 inches

Step-by-step explanation:

Every 25 miles the map shows 1 inch
100 miles is equal to 4 x 25 miles, thus 100 miles on the map will be 4 times longer than 1 inch => 4 inches
