Answer:
1 3/4 gallon or 1.75
Step-by-step explanation:
1 (1/4) = 5/7
5/4 = 5/7
5/4 = 1.25
1.25/x = 5/7
7(1.25) = 5x
5x = 8.75
x = 1 3/4
You would not subtract 2 from 6 because they are not like terms that you can combine - one of them contains a variable.
You would solve this equation like so:
6z - 2 = 0 The given equation
6z = 2 Add 2 to both sides
z = 1/3 Divide both sides by 6
Answer:
z = 1/3
Hope this helps.
First you find 80% of 90. Set up the proportion:
80 X
—— = —-
100 90
I’m simplifying the 80/100 so it’ll be easier to solve:
4 X
— = —-
5 90
Then cross multiply:
4(90) = 5x
360 = 5x
x = 72
So 80% of 90 is 72. (Or you could have multiplied 90 by 0.8 as a shortcut). Now you find 15% of 72. You can either multiply 72 by 0.15 or set up the proportion like this:
15 X
—— = —-
100 72
Cross multiply and solve. You should get 10.8
Answer:
Step-by-step explanation:
The given expression is :
We need to write the equivalent expression for the above expression.
Taking like terms together,
So, the equivalent expression is .
Answer:Let n = the smallest integer
Then the other integers are n+1, n+2, n+3 and n+4
Sum = n + n+1 + n+2 + n+3 + n+4 = 5n + 10 = 5(n + 2)
So the sum is always divisible by 5, for any value of n
