Answer:

a = -32

Step-by-step explanation:

3a−(10+5a)=54

Distribute the minus sign

3a−10-5a=54

Combine like terms

-2a -10 = 54

Add 10 to each side

-2a-10+10 = 54+10

-2a = 64

Divide by -2

-2a/-2 = 64/-2

a = -32

Answer:

a = -32

Step-by-step explanation:

3a - (10 + 5a) = 54

Distribute the negative sign as if it were -1.

3a - 10 - 5a = 54

Combine like terms on left side.

-2a - 10 = 54

Add 10 to both sides.

-2a = 64

Divide both sides by -2.

a = -32

in a fundraiser, Mrs. Smith pledges $1 for each mile walked . if Sam walks 20 miles how much will Mrs. Smith donate? what is yhe
EleoNora [17]
Mrs. Smith donated $20
The constant proportionality is $1 because no matter what, Mrs. smith will donate $1 for each mile. So if Sam were to only walk 1 mile, mrs. smith would donate $1. Or seen as a 1:1 proportion.

Find the range of possible measures of x if each set of expressions represents measures of the sides of a triangle.
sergiy2304 [10]

Answer:

  • C. x > 3/2

Step-by-step explanation:

<u>According to the triangle inequality theorem, any side length is less than the sum of the other two:</u>

  • x < 2x + 1 + x + 4 ⇒ x < 3x + 5 ⇒ 2x > - 5 ⇒ x > - 2.5
  • 2x + 1 < x + x + 4 ⇒ 2x + 1 < 2x + 4 ⇒ 1 < 4, any value of x
  • x + 4 < x + 2x + 1 ⇒ x + 4 < 3x + 1 ⇒ 2x > 3 ⇒ x > 3/2

<u>Common solution of the three inequalities above is:</u>

  • x > 3/2

Correct choice is C

Answer:  12

<u>Step-by-step explanation:</u>

Average rate of change is the slope (m) between the two coordinates (-1, 3) and (1, 27).

m=\dfrac{y_2-y_1}{x_2-x_1}

m = \dfrac{27-3}{1+1}

   =-\dfrac{24}{2}

   = 12
