Answer: choice a

Step-by-step explanation:

Set up your variables. For this question lets use x, y, and z.

the equations will be . .

x + y + z = 165

x = 2y - 65

z = y -10

If we now substitude the equations for x and z with the first equation we cans solve for y. Hence the equation will be  . . .

2y - 65 + y + y -10 = 165

y = 60

then substitude the equations for x and z with y.

your answer should match choice a.

Find the mean of the first four test scores first.
(Add all numbers in set and divide by how many numbers there are)
81 + 87 + 71 + 89 = 328 / 4 = 82

Then, find the mean with the 85 added as the fifth term.
81 + 87 + 71 + 89 + 85 = 413 / 5 = 82.6

The impact that the 85 had on the mean test score was that the mean/average increased by 0.6.

Solve for x. Show each step of the solution. <br><br> 4(8-x)-32=98-5(3x+24)
Firlakuza [10]

Answer: x=−2

Step-by-step explanation:

Let's solve your equation step-by-step.

4(8−x)−32=98−5(3x+24)

Step 1: Simplify both sides of the equation.

4(8−x)−32=98−5(3x+24)

(4)(8)+(4)(−x)+−32=98+(−5)(3x)+(−5)(24)(Distribute)

32+−4x+−32=98+−15x+−120

(−4x)+(32+−32)=(−15x)+(98+−120)(Combine Like Terms)

−4x=−15x+−22

−4x=−15x−22

Step 2: Add 15x to both sides.

−4x+15x=−15x−22+15x

11x=−22

Step 3: Divide both sides by 11.

11x /11 = −22 /11

x=−2
