For the first one, its 86 square in, and the second one is 45 square cm.
She would pay $85.10 in total
74(.15)= 11.1
74+11.1= 85.10
Answer:x=-2 y=-6
Step-by-step explanation:
11x+4y=-46..........(1)
7x-4y=10..............(11)
Add (1) and (11)
11x+7x+4y-4y=-46+10
18x=-36
Divide both sides by 18
18x/18=-36/18
x=-2
substitute x=-2 in (11)
7x-4y=10
7(-2)-4y=10
-14-4y=10
Collect like terms
4y=-14-10
4y=-24
Divide both sides by 4
4y/4=-24/4
y=-6
Answer:
2
Step-by-step explanation:
Using the rule of logarithms
•
x = n ⇔ x = 
let
64 = n, then
64 = 
note that 64 = 8², thus
8² =
⇒ n = 2
