A school is getting repainted. The painters arrive with 73 gallons of paint, and they will use 2 gallons to paint each classroom. After the painters finish painting all the classrooms, they will have 37 gallons of paint left. How many classrooms are there?
Write and solve an equation to find the answer.
_____classrooms
Answer:
___18___ classrooms
Step-by-step explanation:
Let the number of classrooms be x.
Each classroom uses 2 gallons, so x classrooms use 2x gallons.
They paint x classrooms using 2x gallons.
They still have 37 gallons left, so the entire amount of paint they had before they started painting was
2x + 37.
We are told they started with 73 gallons, so 2x + 37 must equal 73.
The equation is
2x + 37 = 73
Now we solve the equation.
Subtract 37 from both sides.
2x = 36
Divide both sides by 2.
x = 18
Answer: ___18___ classrooms
Given 4(3x-8)=52 prove x=7
please help
Answer:
4(3x-8)=52
divide both sides by 4
4/4(3x-8)=52/4
3x-8=13
add both sides by 8
3x-8+8=13+8
3x=21
divide both sides by 3
3x/3=21/3
x=7

Identify all values of x
Step-by-step explanation:
(x - 3)/x = -8/(x + 3) , x ≠ 0 or -3
(x - 3)(x + 3) = -8x
x² - 9 = -8x
x² + 8x - 9 = 0
x² + 9x - x - 9 = 0
x(x + 9) - 1(x + 9) = 0
(x + 9)(x - 1) = 0
x = -9
x = 1
x ≠ 0 or -3
-9 ≠ 0 or 3 PROVED
x ≠ 0 or -3
1 ≠ 0 or -3 PROVED
Value of x is -9 and 1When simplifying the expression, it is equivalent to what number?

Two similar triangles are shown below which two sets of angles are corresponding angles p and q
Answer: p = 30 q = 30 (if not touching edge of hexagon but if it is touching edge one of the pairs) then p or q = 120 and p and q = 30
Step 1) Sum of an interior angle of a polygon = 720 degree where n = 6 as 6 exterior sides = (n-2) * 180 = (6-2) * 180 = 4 * 180 = 720 degree Where the measure of each angle of a hexagon = 720/ 6 = 120 degree Step 2) Then show 3 angle letter names = 180 degree Step 3) Angle name letters + 2 angle (other two names letters inside within triangle) add up to 180 degree Step 3) State since triangle name (of all letters within one triangle) is Isosceles Step 4) Triangle (state same triangle letters with number 2 in front) = 180 - 120 = 60 then state triangle (letter name) / 2 = 30 degrees obviously the 120 and 60 differentiates if not a hexagon to a pentagon if not a hexagon = (3 *180) / 5 = 108 then due to isosceles (180 - 108)/ 2 = 72/2 = 36 degree for a pentagon or 30 degree each for p + q for a hexagon etc

A bag of chips contains 621 calories and serves 4.5 people. How many calories are in each serving?
Answer:
138 calories/serving
Step-by-step explanation:
Find the unit rate, the measure of how many calories are in each serving:
621 calories
-------------------- = 138 calories/serving
4.5 servings
The number of calories are in each serving is 138.
Given that, a bag of chips contains 621 calories and serves 4.5 people.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Number of calories in each serving = Total number of calories/Number of servings
= 621/4.5
= 138 calories
Therefore, the number of calories are in each serving is 138.

Answer: Malik uses an app on his phone to track how far he rides his bike. Yesterday, he biked a new trail in a total of 57.5 minutes, including a 2.5-minute water break. The app notified Malik that he rode 10 miles. What was Malik's average pace while biking?
Answer:
5.5 Minutes per mile
Step-by-step explanation:
Malik biked 10 miles at a pace of p minutes per mile. His water break added 2.5 minutes to his time. It took him a total of 57.5 minutes to complete the trail. This equation represents the situation.
10p time spent biking
+
2.5 time for water break
=
57.5 total time
Now, solve the equation for p.
10p+2.5
= 57.5
10p
= 55 Subtract 2.5 from both sides
p
= 5.5 Divide both sides by 10
Malik's average pace was 5.5 minutes per mile.
