Answer:
The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210
Step-by-step explanation:
Let
x ---> the number of gift wrap rolls for solid colors sold
y ---> the number of gift wrap rolls for sprint patterns sold
we know that
---->
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B

solve for y




<em>Find the value of x</em>
----> 
therefore
The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210
16^x / 4^x
= 4^2x / 4^x
= 4^x so E is one choice.

Answer:
6
Step-by-step explanation:
Number = x
5x + 18 = 48
5x = 30
x = 6
Answer:
Step-by-step explanation:
f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x). To find ... 4 + 6 = 10. (h – g)(2) = h(2) – g(2). = –3 – 6 = –9. (f × h)(2) = f (2) × h(2). = (4)(–3)= –12 ... simplified form: 6x + 3h – 1

Answer:
Step-by-step explanation:
Let x represent the amount invested at 8%. Then the total interest earned is ...
0.06(7000 -x) +0.08x = 480
420 +0.02x = 480 . . . . . . . . . eliminate parentheses
0.02x = 60 . . . . . . . . . . subtract 420
x = 60/0.02 = 3000 . . . . . divide by the coefficient of x
$3000 was invested at 8%; $4000 was invested at 6%.
