The sum of two numbers is 91.one is 37 more than the other.Find the numbers
Step-by-step explanation:
Hey there!!
Here, According to the question;
Let one number be x then another number will be x+37. (as one number is 37 more than other number. )
Now,
Their sum is 91.
It would be like;
[tex]x + (x + 37) = 37[/tex]
[tex]2x + 37 = 91[/tex]
[tex]2x = 91 - 37[/tex]
[tex]x = \frac{54}{2} [/tex]
Therefore the value of x is 27.
So, one number is 27 and another number is 64.
Hope it helps....

Find the equation of the line with slope −2 and that contains the point (−9,−7). Write the equation in the form y=mx+b and identify m and b.
Answer:
m = -2 which is the slope
b = 2 which is the intercept of the line.
Step-by-step explanation:
We have that the line must pass through the following points (-9, -7). These two points are any two of the numerous points that pass through the straight line. We can designate variables to each of these points as shown below
Let us take our [tex]y_1 = -7[/tex] and [tex]x_1 = -9[/tex]
Given the slope as [tex](y-y_1)/(x-x_1)=-2[/tex]
[tex](y--7)/(x--9) = -2[/tex]
[tex](y +7)/(x+9) =-2[/tex]
[tex]y +7 = -2(x+9)[/tex]
[tex]y =-2x+2[/tex]
We are given the form: y=mx+b.
we can compare this with our equation for the line. [tex]y =-2x+2[/tex]
We can see that m = -2 which is the slope and b = 2 which is the intercept of the line.

A school bus requires 40 liters of fuel per week. If your school district runs 5,000 school buses, how many liters of fuel will the buses consume in 52 weeks? A. 15 million liters B. 10 million liters C. 10.4 million liters D. 200 million liters
Answer:
C. 10.4 million liters.
Step-by-step explanation:
1. First, you want to create an equation to help you solve this. You know that there are 5,000 school buses and they use 40 liters of fuel per week. So, you know that 5,000 · 40x would be the amount of fuel for x weeks (where x is the number of weeks).
2. To figure out how many liters would be used in 52 weeks, simply put 52 in for x. So, the expression is 5,000·40(52).
3. Multiply 40(52) to get 2,080. Your expression now looks like this: 5,000·2,080
4. Multiply 5,000(2,080) to get your answer of 10,400,000 liters.
Hope this helps! :) If you could give me Brainliest that would be super helpful!
21-7x=7(3-x)
Solve this please!!!!!!!!!!
Answer:
All real numbers
Step-by-step explanation:
21 - 7x = 7(3 - x)
21 - 7x = 21 - 7x
Since both sides of the equation are equal, the answer is all real numbers.
[tex]21 - 7x = 7(3 - x)\\21 - 7x = 21 - 7x\\-7x + 7x = 21 - 21\\x \in \mathbb{R}[/tex]

Sal has 5 balloons. He has 3 red balloons. The rest are blue. Kay has 5 more blue balloons than sal. How many blue balloons does kay have?
Answer:
Kay has 7 blue balloons
Step-by-step explanation:
if Sal has 5 red balloons and 2 blue balloons and Kay has 5 more blue balloons than Sal the Kay has 7 blue balloons
The number of blue balloons does Kay have is 7.
Given that, Sal has 5 balloons. He has 3 red balloons. The rest are blue.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of blue balloons does Kay have be x.
Number of blue balloons Sal have = 5-3=2
The number of blue balloons does Kay have = Kay has 5 more blue balloons than Sal
⇒ x = 2+5 = 7
Therefore, the number of blue balloons does Kay have is 7.

* For his phone service, Goran pays a monthly fee of $24, and he pays an additional $0.06 per minute of use. The least he has been charged in a month is $93.96
*What are the possible numbers of minutes he has used his phone in a month?
*Use m for the number of minutes, and solve your inequality for m.
Answer:
[tex]m \geq 1166[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = \$24[/tex]
[tex]Charges = \$0.06[/tex] per minute
[tex]Least\ Monthly\ Charges = \$93.96[/tex]
Required
Determine the possible number of minutes
If for 1 minute, he's charged $0.06;
He'll be charged $0.06m for m minutes
Representing this as an inequality, we have:
[tex]Base\ Amount + m\ Charges \geq\ Least\ Monthly\ Charges[/tex]
[tex]24 + 0.06m \geq 93.96[/tex]
Solve for 0.06m
[tex]0.06m \geq 93.96 - 24[/tex]
[tex]0.06m \geq 69.96[/tex]
Solve for m
[tex]m \geq 69.96/0.06[/tex]
[tex]m \geq 1166[/tex]
This implies that, he's charged for at least 1166 minutes
find the end point m

Answer:
(-4, 7)
Step-by-step explanation:
The x and y coordinates of the midpoint are the average of the x and y coordinates of the endpoints.
-1 = (2 + x) / 2
-2 = 2 + x
x = -4
5 = (3 + y) / 2
10 = 3 + y
y = 7
The coordinates of point S are therefore (-4, 7).
Jean masear is a saw operator in a lumber mill. He works 40 hours a week and earns $630 per week. What is his hourly pay rate
Answer:
[tex]\boxed {\tt \$15.75 \ per \ hour}[/tex]
Step-by-step explanation:
We want to find Jean's hourly pay rate. In other words, his pay per hour.
We can find the pay rate by dividing the money he is paid by the number of hours worked.
[tex]pay \ rate =\frac{money \ paid }{hours}[/tex]
He is paid $630 for 40 hours.
[tex]money \ paid= $630 \\hours= 40\ hours[/tex]
[tex]pay \ rate = \frac{\$630}{40\ hours}[/tex]
Divide.
[tex]pay\ rate = \$15.75 / hour[/tex]
His hourly pay rate is $15.75 per hour.

Nash is training for a marathon and decides to train for 26 miles every week. In the first week, the ratio of the number of miles he ran to the number of miles he walked 3:10. In the fifth week the ration ran to walked is 8:5. How many miles did nash run in week 5
Answer:
16 miles
Step-by-step explanation:
From the question given above, the following data were obtained:
Miles per week for training = 26 miles.
In the 5th week:
Ratio of miles ran to miles Walked is 8:5
Thus, we can obtain the miles ran by Nash in the 5th week as follow:
Ratio ran = 8
Ratio walked = 5
Total ratio = 8 + 5 = 13
Miles per week for training = 26 mile
Mile ran in the 5th week = 8/13 × 26
Mile ran in the 5th week = 8 × 2
Mile ran in the 5th week = 16 miles
Therefore, Nash ran 16 miles in the 5th week of training.

Answer:
x = 6, y = 8
Step-by-step explanation:
First, we need to find the scale factor from the smaller polygon to the larger polygon. To do this, we can calculate 18 / 12 which is 1.5. Therefore, we can write the following equations:
x · 1.5 = 9 → x = 6
y · 1.5 = 12 → y = 8

St. Paul, MN Was - 170. Over a period of three
hours, the temperature rose 5°F per hour.
After three hours, what the was the
temperature?
Answer:
-2°F
Step-by-step explanation:
The starting temperature was -17°F. If the temperature rose 5°F per hour, and we're looking for the temperature after three hours, the change in temperature was +15°F.
-17 + 15 = -2°F
