Answer: 5m - (-8) = (-4) + 2m= m=−4 solvi

3x + 8 < 2x - 15= x<−23

Step-by-step explanation: 5m - (-8) = (-4) + 2m= m=−4

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*m-(-8)-((-4)+2*m)=0

Pull out like factors :

3m + 12 = 3 • (m + 4)

Solve : m+4 = 0

Subtract 4 from both sides of the equation :

m = -4

3x + 8 < 2x - 15

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

3*x+8-(2*x-15)<0

Subtract 23 from both sides

x < -23

Hey there!

When we multiply fractions and whole numbers, we simply take that whole number and put it over them, and just multiply across. That gives us:

$\frac{1}{2}x*8 = \frac{8}{2} = 4$

Notice how it's four, because when we have a fraction, we divide. 8 divided by 2 equals four. Next:

$\frac{1}{4} *4 = \frac{4}{4} = 1$

4/4 is equal to 1 because 4 divided by 4 is one. 4 goes into 4 once. Next, we have:

$\frac{1}{3}*6 = \frac{6}{3} = 2$

That's because 6/3 = 2.

Hope this helps!

Answer:

b= 70

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to exterior angle.

a+b = 140

We know that a = b since PQ = RQ The angles opposite the equal sides in an isosceles triangle are equal

b+b = 140
