Answer:
n-7=13
Step-by-step explanation:
We need to find an equation that represents the expression: "Seven less than a number is thirteen".
It means that a number minus 7 equals 13. So, the correct option is: n-7=13
Bonus: Solving for 'n' we have that n=20.
So, Seven less than 20 equals 13!!
Answer: 3.
The volume for all the boxes is 50in³ because 1 * 1 * 1 * 50 = 50.
Next, let's prime factorize 50 so that (using multiplication) we can find all the different bases.
50 ÷ 2 = 25
25 ÷ 5 = 5
5 ÷ 5 = 1
2 * 5² * 1
height x length x width
1 x 5 x 10
1 x 2 x 25
1 x 1 x 50
Answer:
350 ml
Step-by-step explanation:
70% of 500 ml = 0.7*500 ml = 350 ml
7/8 gallons in 1/2 hour
Looking for gallons per hour, or
.
So, this is basically a division problem of 7/8 divided by 1/2. Dividing by a fraction is the same as multiplying by that fraction's reciprocal.
Now we simplify by a factor of 2:
And here we are! There are 7/4 gallons leaking per hour. This is the same as 1.75 gallons per hour. Hope this helps! :)
