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

Answers:
y=2x2−20x+51
Step-by-step explanation:
Vertex:
(5,1)
Focus:
(5,98)
Axis of Symmetry:
x=5
Directrix:
y=78
1) A(1;2) and slope=3.
slope-interception form is y=s*x+i, where s - slope, i - interception.
if to substitute the given coordinates and slope into the equation, then 2=3*1+i, ⇒ i=-1. It means, the required equation is:
y=3x-1.
2) A(1;2) and B(3;-2).
the common form is:
[tex]\frac{x-X_B}{X_A-X_B} =\frac{y-Y_B}{Y_A-Y_B}.[/tex]
If to substitute the given coordinates into the common form, then:
[tex]\frac{x-3}{1-3} =\frac{y+2}{2+2} ; \ => \ \frac{x-3}{-2} =\frac{y+2}{4}; \ => \ y=-2x+4.[/tex]

Answer:
d
Step-by-step explanation:
statistic is a number that represents as numerical data
. An example of statistics is a report of numbers saying how many followers of each religion there are in a particular country.
Statistic exists a number that designates as numerical data. Average number of all high school graduates who will attend college
What is Statistic?Statistic exists a number that designates as numerical data. Statistics exist described as numerical data and is the field of math that negotiates with the collection, tabulation, and interpretation of numerical data. An illustration of statistics exists as a report of numbers expressing how many followers of each religion there exist in a certain country. Numerical data exists as a data kind described in numbers, rather than natural language description. Sometimes named quantitative data, numerical data exists ever gathered in number form.
Therefore, the correct answer is option d.) Average number of all high school graduates who will attend college.

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.

is the total number of crackers Matthew eats during the week?
Answer:
36 crackers
Step-by-step explanation:
If he normally eats 8 crackers every weekday, he consumes about 40 crackers.
On the last day however, he dropped 4, so he only ate 4.
8 * 4 = 32
32+ 4
= 36

y=2x+4 cannot figure out?
Answer: M= 2 C= 4 (0,4)
Step-by-step explanation:
Formula- y=mx+c where m is the gradient and c is the y intercept
In y=2x + 4,
2 is in the place of m and 4 is in the place of c. So, m= 2 and c=4. The coordinates of the y intercept would be (0,4)

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
