You and your family go out to dinner to build a total of $54 plan to leave 20% tip how much tip should you leave
loris [4]

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,

A=\dfrac{20}{100}\times 54\\\\=\$10.8

So, $10.8 is left.

the mean of 11 numbers is 7. one of the numbers, 13, is deleted. what is the mean of the remaining 10 numbers?
Alex Ar [27]
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

What is the solution to 7x + 6y if y = 10 and x = 2?
lapo4ka [179]

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.

Maria has 3 more than twice as many crayons as Elizabeth. How many crayons does Maria have? C = crayons 2C + 3 3C + 2 3 + 2 + c
nadya68 [22]
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 :)
