Answer:
220 miles
Step-by-step explanation:
.18m + 11d = 61.60
d = 2
.18m + 22 = 61.60
Subtract 22 from both sides
.18m = 39.60
Divide both sides by .18
m = 220
I'm assuming that since 87% failed, that would the remaining 13% was a success. If that assumption is correct, than we simply have to take:
.13 * 13531 = 1759.03 products were successful.
The summation symbol means we use the variable i in the equation from the given range. In this case, we are given with the equation 3 i - 15 and i ranges from 2 to 7. The summation using simply the calculator is equal to -9. The answer to this problem is -9.
Hi there!
So the format of slope-intercept form is:
y= mx+b
m= your slope
x = just a variable
b= your y- intercept
Using those hints, see if you can figure out the answer! :)
Hope this helped!

If you're super stuck, your answer would be:
Slope: -7
Y- intercept: 12
Divide 31 by 50 and that will give you .62 move the decimal point two places to the right and that gives you 62%. :)
