Answer:
3/4 times 18= 13.5
31.5-13.5=18
It cost 18 dollars for the skirt with a discount.
It cost 13.5 for the blouse as opposed to the original price of 18 dollars.
18(skirt)+13.5(blouse)=31.5
If you set up a proportion to find the original price of the skirt you will get the answer.
18/x=75/100
75x=18 times 100
75x=1800
75x/75=1800/75
x=24
The original price of the skirt is 24 dollars.
Step-by-step explanation:
-2log_5 7x = log_5 2
log_5[1/(7x)^2] = log_5 2
log_5(1/49x^2) = log_5 2
log_5(1 - 49x^2) = log_5 2
1 - 49x^2 = 2
You finish.
Answer:
x+2a=12+ax-6a
Step-by-step explanation:
collect liked terms:
x+2a=12+ax-6a
2a-ax+6a=12-x
factorize a on the left hand side:
a(2-x+6)=12-x
divide both sides by (2-x+6) :
a(2-x+6)/(2-x+6)= 12-x/(2-x+6)
a= 12-x
____
(2-x+6)
= 9 16/12
= 10 4/12
= 10 1/3
Okay, so u just divide numerator and the denominator... you get 0.76.
