6= w-56/-7 , what is the value of w?
Answers
Answer:
-2
Step-by-step explanation:
w = 14
Just to confirm, I’m reading the right side as a fraction with w - 56 as the numerator and -7 as the denominator.
Multiply both sides by -7:
- 42 = w - 56
Add 56 to both sides:
14 = w
Substitute back in to check:
6 = 14 - 56 / -7
6 = -42 / -7
6 = 6 :)

A large pizza costs $15.99. A second large pizza is 2/3 off. Using an estimate, approximately how much will it cost for 2 large pizzas?
Answers
Since 2/3 of 15.99 (which is how much is being discounted or taken off) is 10.66, you subtract 15.99 by 10.66, then add 15.99 to get the full price of the two pizzas

Brandon treated his friends to lunch which cost him $32.60. He left a 20% tip for the waitress. How much was his total bill including tip?
Answers
Answer:
39.12
Step-by-step explanation:
First you find 20% of 32.60
32.6 * 20/100
32.6 * 0.2
= 6.52
So the tip is $6.52
Add the tip and the regular cost
32.60 + 6.52 = 39.12
$39.12 is the total amount he paid

The sum of 2 numbers is 30. Their product is 176. What are the 2 numbers?
Answers
Answer:
Step-by-step explanation:
x, 30 - x add to 30. The other condition says
x (30 - x) = 176. Multiply it out.
30x - x^2 = 176, so
x^2 - 30x = -176, complete square by adding 15^2 to both sides
(x - 15)^2 = 225 - 176 = 49, take square root
x - 15 = 7, so one number is:
x = 22 and the other is 30 - x = 8.
A circular pool has a radius of 10 feet. What is the area of the pool? Use 3.14 for it. The area of the pool is about ft?
Answers
Answer:
314ft^2
Step-by-step explanation:
The area of a circle is found using this equation:
A=3.14r^2
r = radius
so if we know the radius is 10ft, we can put that into the equation and it will read:
A=3.14(10)^2
^2 means squared, for clarification.
Using PEMDAS we know to do exponents first
A=3.14(100)
Now multiply
A=314
and don't forget to add your units and square!
A=314ft^2
