EXPERTS PLEASE HELP!!!!!!!!!!!!!!

Arturiano [62]

Answer:

1. D

2. x=65

Step-by-step explanation:

Hi!

Your answer is D because 78 is 120% of x

120% in decimal point is 1.2.

So it's 1.2x is the same as 120% of x

For question 8:

1.2x=78

Isolate x by divide 1.2 on both sides

78/1.2=65

4x + 6y = 18 & 4x – 2y = 10

kherson [118]

Answer:

x=4.875

y=-0.25

Step-by-step explanation:

4x – 2y = 10

2x-y=10

y=2x-10

4x + 6y = 18

2x+3(2x-10)=9

8x=39

x=4.875

y=2(4.875)-10

y=-0.25

Rueben has scored 81 , 89 , 90 , 83 , and 77 on his previous five tests. what score does he need on his next test so that his av

lawyer [7]

Let x = the next score

If (81 + 89 + 90 + 83 + 77 + x) ÷ 6 = 82

⇒ 420 + x = (82 × 6)

⇒ x = 492 - 420

x = 72

Thus to get an 82 average he need to get 72 on his next test.
