7-5*14=62
The equation above is how you would write it with a variable.
The number is 14.
This is because if you do 14 times 5, the answer is 70. Then If you subtract from that, it would be 62.
You can also do 62+7, which is 70, and then divide that by 5 and you will still get 14.
Answer:
a = 132; b = 12; c = 36
Step-by-step explanation:
a = b + 120
b = b
c = 3b
a + b + c = 180
(substitute these into the above equation)
b + 120 + b + 3b = 180
5b + 120 = 180
-120 -120
5b = 60
/5 /5
b = 12
(substitute b back into the first equations)
a = (12) + 120 = 132
b = (12)
c = 3(12) = 36
(check: 132 + 12 + 36 = 180)
Answer:

Step-by-step explanation:
we have

solve for x
That means ----> isolate the variable x
Divide by k both sides

Adds 7 both sides

Rewrite

Answer:
6 days
Step-by-step explanation:
The equation for first warehouse would be:
210 + 90x
The equation for 2nd warehouse would be:
180 + 120x
Where x is he number of days.
<em><u>In how many days will the first warehouse have 1.2 times less potatoes than the second warehouse?</u></em>
This means the first warehouse expression TIMES 1.2 would give us 2nd warehouse expression. Equating and solve:

So it would require 6 days
