Answer: 61.5
Step-by-step explanation: gave up on deltamath
(1 + v)(v - 7)
1*(v - 7) + v(v - 7)
1*v - 1*7 + v*v - v*7
v - 7 + v² - 7v
v² - 7v + v - 7
v² - 6v - 7
I hope this helps.
Hi.
First, let's calculate how many miles he has left.
80 - 14 = 66
Now, to figure out how many miles a day in 6 days, divide.
66/6 = 11
Xavier should bike 11 miles on each of the 6 remaining days.
Answer:
25 = total number of paintbrushes
Step-by-step explanation:
number with yellow handles = total number of paintbrushes * percent with yellow handles
We know that 15 have yellow handles and the percent with yellow handles is 60
15 = total number of paintbrushes * 60%
We need to change the percent to a decimal
15 = total number of paintbrushes * .60
Divide each side by .60
15/.60 = total number of paintbrushes * .60/.60
25 = total number of paintbrushes
Answer:
A = 33.33
Step-by-step explanation:
P = 0.006A^2 - 0.02A + 120
*** P = 126 ***
126 = 0.006A^2 - 0.02A + 120
126 = (3/500)A^2 - (1/50)A + 120
*** multiplied with 500 on both sides ***
63000 = 3A^2 - 10A + 60000
63000 - 3A^2 + 10A - 60000 = 0
3000 - 3A^2 + 10A = 0
3A^2 - 10A - 3000 = 0
3A^2 + 90A - 100A - 3000 = 0
3A(A + 30) - 100(A + 30) = 0
(A + 30)(3A - 100) = 0
A + 30 = 0 | 3A - 100 = 0
A = -30 | 3A = 100
A = -30 | A = 100/3
Human age cannot be negative so
A = 100/3 = 33.33
