Answer:
x = 3
Step-by-step explanation:
Simplify the equation to -3x + 12 + x = 2x, and then to -2x + 12 = 2x. Now you have to make the x values on one side so now you are left with 12 = 4x, so you just simplify by dividing 12 by 4. The answer is 3 = x.
Answer:
17 Blueberry and 20 Apple Pies
Step-by-step explanation:
17 (Blueberry Pies) x 14 (Cost For Each) = 238
22 (Apple Pies) x 10 (Cost For Each) = 220
220 + 238 = 458 (Total Pies Sold On Staurday)
Answer: (0,0)
Step-by-step explanation:
A) 2^(x+3)= 4^(2x)
make base number the same
2^(x+3)= 2^2 (2x)
set the exponents equal to eachother
x+3=2 (2x)
x+3=4x
-x both sides
3=3x
÷3 both sides
x=1
b) 16^(1/5)×2^(x)=8^(3/4)
make base same number
2^4 (1/5)×2^(x)=2^3 (3/4)
2^(4/5)×2^(x)=2^(9/4)
set exponents
4/5 +x=9/4
-4/5 both sides
x= 29/20
