Answer:
The equation is 
x = 
Step-by-step explanation:
The Equation is formed from two sides equal to each other
- In the algebraic statement "is" means equal
- In the algebraic statement "of" means times (×)
∵ One eighth means 
∴ Negative one eighth means
→ Assume that the number is x
∵ "of" means times
∴ Negative one eighth of a number = × (x)
∴ Negative one eighth of a number = x
∵ Negative one eighth of a number is
→ "is" means equal, so the left side is x and the right side is
∴ x = ⇒ Equation
∴ The equation is x =

Step-by-step explanation:
Answer:
10.875 total, 1.5 times each are below.
Step-by-step explanation:
1.5 (1 1/2) x 1.5 = 2.25
0.5 (2/4) x 1.5 = 0.75
0.125 (1/8) x 1.5 = 1.875
4 x 1.5 = 6
2.25 + 0.75 + 1.875 + 6 = 10.875 total
Answer:
Inequality: .80x +21 ≤ 82
Answer: 76.25 miles in total
Step-by-step explanation:
Hi,
An inequality to represent this is .80x +21 ≤ 82
(.80 is the cost per mile and x is the number of miles driven. 21 is the fee that must be paid no matter what and the 82 is the total cost they can pay. We use the ≤ sign to say they can spend less than or equal to 82. The phrase "at most" means we can use the ≤ sign).
Now we solve...
.80x + 21 ≤ 82
Subtract 21 on both sides...
.80x ≤ 61
Now, divide by .80 on both sides...
x ≤ 76.25
He can drive up to 76.25 miles in total
Hope this helps :)
