Let the number be x.
7x-x=42
6x=42
x=7
the number is 7
Explanation:
<em>What is an eighth of 32?
</em>
An eighth of 32 means 32 is divided into eight equal parts.
Let's use a fact family for this problem:
8 * ? = 32
32 / 8 = ?
-------------
8 * 4 = 32
32 / 8 = 4
An eighth of 32 is 4.
Five eights of 32:
Five eighths of 32 is five times four which is 20
20 is 5 eighths of 32
5/8 * 32 = 20
32 * 5 / 8 = 20
The answer is 32.
7*24 = 168 quarts of water per day goes into barrel.
25*48 = 1200 quarts of waste water picked up
1200÷168 =7.142857143
Answer:
30
Step-by-step explanation:
Pythagorean theorem states that a^2 + b^2 = c^2
this theorem only works on triangles with an angle of 90 degrees or a right triangle.
18^2 + 24^2 = 900
the square root of 900 is 30
I did the square root of 900 because the square root is the 'opposite' of squaring which is what you need to do in order to find 'c' is the Pythagorean theorem. 'a' is 18, and 'b' is 24
Answer is 30
The answer is B, because you will have to multiple 42 by 7 to see how much money he will have in 7 weeks and then you will have to subtract 8 × 8.25 to see how much money he spent on his vacation.
