4x-1 = 3x+3 ——> 4x=3x+4 ——> 1x= 4——> x=4 then plug it in to test and both get 15
Answer:
A. 2^4*5 B. 3^3*2
Step-by-step explanation:
80/2 = 40
40 and 2
20 and 2
10 and 2
5 and 2
So we got 4 2's and one 5 bcz they prime.
27 and 2
9 and 3
3 and 3
So 2 3's and one 2 bcz they prime.
Using sin(A+B) = sinAcosB + cosAsinB
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree
=
55hours times .17 will give you the answer.
Sarah spends 9.35hours on air.
3 5 8
(4 x 10 )(2 x 10 )= 8 x 10
