Step-by-step explanation:
Answer:
u= 2.5
Step-by-step explanation:
Using BIDMAS
Step 1: Expand the bracket
9(u-2) + 1.5u=8.25
9u-18+1.5u=8.25
Step 2: collect like terms
9u+1.5u=8.25+18
10.5u=26.25
Step 3: Divide both sides by 10.5 to get u
u=
= 2.5
Answer:
15%
Step-by-step explanation:
$40 : 100 = 0,4
1% is $0,4
$6 : 0,4 = 15%
So the percentage is 15%.
The answer is -4,0 4,8 because u would solve for one variable in one of the equations and then substitute the result into the other
