Chad washes windows after school to make some extra money. He charges $5.50 to wash each window. If the customer provides the supplies, Chad deducts $3.25 from the total cost. One customer paid a total of $27.50 and did not provide supplies. Which equation could be used to find the number of windows, w, that Chad washed for this customer?
*5.5w - 3.25 = 35.25
The 5.5w part shows that its $5.50 times each window. The -3.25 is because he deducted 3.25 from the total. And then you have the price that he got on the other side.
Here's the work to find the windows in case you want it:
5.5w-3.25=35.25
5.5w=38.50
w=7
He washed 7 windows
Answer:
5.5 w - 3.25 = 27.5

Solve for m. -5m=-35 m=
Answer:
m = 0
Step-by-step explanation:
Solve: Add -35m to -5m
-5m = -35m
+35m
30m = 0 *note: its okay to have 0 in this spot*
divide 0/30
m=0 because you can't divide by 0
The value of m is 7 for the given statement -5m = -35.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given an expression
-5m = -35
Divide by -5 on both sides
m = 7
Therefore, For the given expression -5m = -35 the value of m is 7.

Answer: -3
Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
To turn a fraction into a decimal, all we need to do is divide the numerator by the denominator. But first, we can simplify! -66/22 simplifies to -3/1 when you divide by 22 on the top and bottom. Now, it's a lot easier to divide. -3/1=-3. -3 is technically already a decimal...you just can't see the decimal point. The decimal point is actually behind -3, so it looks like this: -3.0

At a certain bookstore, you get a $5 coupon for every 4 books you buy. What is the least number of books you could buy to get $15 in coupons? Show your work.
Answer:
You need to buy 12 books to get a $15 coupon.
Step-by-step explanation:
Giving the following information:
You get a $5 coupon for every 4 books you buy.
First, we need to structure the total coupon formula:
Total coupon= 5*x
x= pack of four books
Now, for $15
15 = 5x
15/5= x
3= x
4*3= 12
You need to buy 12 books to get a $15 coupon.

What survival rate in the 10th year would make the average rate of loss over the 10-year period equal to 38.0%?
Answer: 63%
Step-by-step explanation:
First find the rate of loss that would cause the average rate of loss over the 10-year period equal to 38.0%.
Assume that rate is x.
38 = (36.2 + 29.0 + 46.2 + 37.5 + 40.9 + 40.0 + 32.6 + 40.5 + 40.1 + x) / 10
38 = (343 + x ) / 10
380 = 343 + x
x = 380 - 343
x = 37%
The survival rate is the opposite of the rate of loss which means that the survival rate is;
= 1 - rate of loss
= 1 - 37%
= 63%
