Answer:
B. 15
Step-by-step explanation:
6×3= 18
18-3= 15
.........
A + T = 165
A= amanda's grade
T= tim's grade
A = T +11
substitute A for T + 11 and you get
T+ 11 +T = 165
combine like terms:
2T + 11 = 165
subtract 11 from both sides:
2T= 154
divide both sides by 2
T = 77 (Tim's grade)
A= 77 +11
so: A= 88 (Amanda's grade)
check answer:
88 + 77 = 165!
Hope this helps!
That picture is a little confusing, if you were trying to solve:
(c^2)^(1/2)=4608^(1/2) (basically it look as if you were trying to simplify the right side...
find the prime factorization of 4608 and see how many perfect squares there are...
4608=2*2*2*2*2*2*2*2*2*3*3=256*9*2 so
c=(16^2*3^2*2)^(1/2)
c=4(3)(2^(1/2))
c=12(2^(1/2))
Answer:
8640
Step-by-step explanation:
40 × 27/12 = 90
90 x 96 = 8640
