Answer:

-45 =x

Step-by-step explanation:

1/5(4x-2.5) = 5(.4x+10) +3 1/2

Change all to decimal form

.2(4x-2.5) = 5(.4x+10) +3.5

Distribute

.8x - .5 = 2x +50 + 3.5

Combine like terms

.8x - .5 = 2x +53.5

Subtract .8x from each side

.8x-.8x - .5 = 2x-.8x +53.5

-.5 = 1.2x +53.5

Subtract 53.5 from each side

-.5 -53.5 = 1.2x +53.5-53.5

-54 = 1.2x

Divide each side by 1.2

-54/1.2 = 1.2x /1.2

-45 =x

How do you round 9.66 to the nearest tenth
Rudik [331]
   The 10th position is the 6 right after the dot. The numeral right after the 6 is closer to the next number. So by rounding it, it becomes 9.7 If the digit to the right is 5 or more, you go up a numeral. If it is 4 or less, you keep it at the numeral that it is. If it had been 9.64 then we would have kept it at 9.6 Hope this helps

At first, Kai earned a score of 80 on a quiz. He discovered that 5 points had been taken
mario62 [17]

Initial score was 80. There was an accidental 5 point deduction. This means anything that gives 85 is the correct answer.

80 + 5 = 85

80 - (-5) = 85
