Answer:
8 would be there.
Step-by-step explanation:
am sorry i cant explain cause my battery is really low
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
12 + 4 + 30 + 16 + 18 = 80
80 ÷ 5 = 16
16-12=4
16-4=12
30-16=14
16-16=0
18-16=2
4 + 12 + 14 + 0 + 2= 32
32 ÷ 5 is 6.4
YOUR ANSWER IS 6.4
Answer:
x = 5.2
Step-by-step explanation:
x/(13-x) = 2/3
3x = 2(13 - x)
3x = 26 - 2x
3x + 2x = 26
5x = 26
x = 26/5
x = 5.2
