What is the value of x​
Artemon [7]

Answer:

45 degrees

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

Thus, x+3x=180

4x=180

Divide both sides by 4:

\frac{4x}{x} =\frac{180}{4}

x=45

Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options.
Elza [17]

Question is Incomplete; Complete question is given below.

Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options. Negative 80 x + 24.5 y minus 56 Negative 80 x + 28 y minus 56 80 x + 28 y + 56 4 (negative 20 x + 7 y minus 14) Negative 4 (negative 20 x + 7 y minus 14)

Answer:

Negative 80 x + 28 y minus 56

4 (negative 20 x + 7 y minus 14)

Step-by-step explanation:

Given:

8(-10x+3.5y-7)

We need to find the equivalent expression for given expression.

Solution:

8(-10x+3.5y-7)

First we will apply distributive property for given expression.

a(x+y) =ax+ay

So we get;

8\times-10x+8\times3.5y-8\times7\\\\-80x+28y-56

Hence first expression equivalent to given expression is -80x+28y-56.

Now again evaluating the expression we get;

We will take 4 as common factor from the expression we get;

-4\times20x+4\times7y-4\times14\\\\4(-20x+7y-14)

Hence second expression equivalent to given expression is 4(-20x+7y-14).
