X = -6.4
First, you would subtract 8 on both sides:
-2.5x + 8 - 8 = 24 - 8
The 8 cancels out on the left side of the equation, and 24 - 8 = 16
Next, divide both sides by -2.5, to get rid of the number that is multiplying by x.
-2.5x/-2.5 = 16/-2.5
= x = -6.4
*Remeber, when dividing a negative by a positive, the answer is negative. In this case, 6.4 is negative.
Answer:
C. 5 3/10
Step-by-step explanation:
After adding the red strips count up the yellow blocks (13 in all)
take away 10 because that makes 1 whole
3 left over out of that 10
4 red strips + 10/10 + 3/10 = 5 3/10
Divide 168.2 / 58 to get 2.9 miles per day on average
128 im pretty sure you would take 16 times 4 which equals 64 then you would multiply 64 times 2 and get 128
