Answer:
Answer is -4.45: I owe $8.75. I have 4.3
Answer:
D
Step-by-step explanation:
using the rule of logarithms
log x - log y ⇔ log (
)
then
(
) =
a -
d
x = 3
Step-by-step explanation:
First we would simplify the left hand side of the equation by expanding the brackets
so 2(4-3x) = 8-6x and
5(2x-3) = 10x-15
This gives the left hand side as 8-6x+10x-15. So the overall equation becomes
8-6x+10x-15 = 20-5x.
Grouping the unknown values on one side and integers on one side of the equation gives us
8-15-20=6x-10x-5x (note the sign changes when numbers and unknown values are moved to the other side of the = sign
Solving further, -27 = -9x i.e x = -27/-9 = 3
Hence x = 3
It should be 11. Consider the side that is 6 is 4 less than the side that is 10. Therefore the side that is x must be 4 less than 15. So it’s 11.
