Answer:
x = 6
Step-by-step explanation:
3 : x = 5 : x+4
3/x = 5/(x+4)
3(x+4) = 5x
3x + 12 = 5x
12 = 2x
x = 6
Answer:
Step-by-step explanation:
I take it that this is some sort of ratio. Start by solving the brackets on the left.
Brackets: 1/3 - 1/10
Brackets: 10/30 - 3/30
Brackets: 7/30
Brackets^2: 49/900
Brackets^2 - 1/5: 49/900 - 180/900
Brackets^2 - 1/5: -131/900
(2/5)^2 = 4/25
The way this read, it should be
Which when you invert and multiply becomes
which finally becomes
Answer:
6 cubic cm
Step-by-step explanation:
A = 6a^2
A = 6(1)^2
A = 6(1)
A = 6
Answer:
n=9
Step-by-step explanation:
You use reverse PEMDAS.
First you would divide by 3 on both sides. This should give you:
n²=81
Then you would find . Which is 9.
Step-by-step explanation:
10=7-m
10-7=-m
3=-m
m=-3
