Answer:
$10.8 is left.
Step-by-step explanation:
Given that,
Total amount = $54
Left amount = 20%
We need to find how much tip should you leave. It means we need to find 20% of 54. So,
So, $10.8 is left.
The mean is the average of the numbers, so if x = all 11 numbers added together, then you have the equation:
x / 11 = 7, so x = 77 (this is all of the numbers added together)
if the number 13 is removed, the equation becomes:
(77 - 13) / 10 = M (M is the new mean)
so the new mean is 6.4
Answer:
A. The height of the water increases 2 inches per minute.
Answer: First we will substitute the numbers in place of the variables in the equation, and then we will use order of operations to solve.
7x + 6y would be equal to:
7(2) + 6(10)
Now we will perform the multiplication:
7 * 2 = 14
6 * 10 = 60
The equation now looks like:
14 + 60
This is equal to 74. Your answer is therefore 74.
Hello,
twice as many means that the number of crayons is multiplied by 2, which would give 2C
she also has 3 more than that so you would add 3 (+3)
this would give you the expression 2C+3
hope this helped :)
