Answer:
First number = 9
Second number = 7
Step-by-step explanation:
Let x be the first number and y be the second.
2x + y = 25
3x - y = 20
1) Add them together.
5x = 45
x = 9
2) Solve for y.
2(9) + y = 25
y=7
3) Check your work on the other equation.
3(9) - (7) = 20
27 - 7 = 20
20 = 20
Therefore the first number is 9 and the second number is 7.
Is 3927 divisible by 9?

C. translated down 2 units
---The "-2" located on the outside of f(x) tells us that the y-values are being changed. With that, the graph can be moved up or down. The presence of the negative/subtraction sign tells us that the graph is moved down.
D. translated right 4 units
---The "-4" located with the x in f(x) tells us that the x-values are being changed. The only tricky thing about this is that the direction of the movement is actually the opposite of the sign. So with the negative/subtraction sign, the graph is moved to the right instead of the left.
Hope this helps!
Using Tisha's ratio of 4:6 of popcorn to candy lovers, how many popcorn lovers to candy lovers
would there be if Tisha had 50 friends? 100 friends?
Answer:
50 friends = 20:30
100 friends = 40:60
Step-by-step explanation:
Let candy lovers = cl
Let popcon lover = pl
Let total = t
1) Let's write in ratio form.
pl : cl
4 : 6
2) Add the ratios (4 + 6 = 10) and write it in fraction form multiplying the desired amount.
pl: [tex]\frac{4}{10} * 50[/tex]
cl: [tex]\frac{6}{10}*50[/tex]
3) Solve them.
pl: 20
cl: 30
3) Take the same steps to get the ratio for 100 friends.
pl: [tex]\frac{4}{10} * 100[/tex]
cl: [tex]\frac{6}{10} * 100[/tex]
-------------------------
pl: 40
cl: 60

The average vehicle releases 1.39grams of NOx per mile driven. If a vehicle is driven 22,000miles per year for 15 years, how much NOx does that vehicle release
The quantity of NOx the vehicle will release in 15 years for running 22000miles each year will be 458700 grams.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number.
here in the question we will multiply the Nox released by the vehicle per year to 15 years.
Given that: Vehicle releases 1.39 Nox per mile
Now if vehicle is running 22000 miles per year so the Nox released per year will be =22000x1.39=30580 grams per year
For 15 years the NOx released by the vehicle will be = 30580x15=458700 grams
Hence the quantity of NOx the vehicle will release in 15 years for running 22000miles each year will be 458700 grams.

what’s 110 decreased by 30%
Answer:
110 decreased by 30% is 77.
Step-by-step explanation:
To do this, what we do is simply take 30% of 110 and subtract it from 110.
30% of 110. A trick to easily figure this out is multipling 110 by 30 and dividing by 100.
110*30 = 3300
3300 / 100 = 33
110 - 33 = 77
110 decreased by 30% is 77.

How many unit cubes need to be added to the figure so that it will have a total
volume of 12 cubic units?
Answer:
c. 4
Step-by-step explanation:
see how many cubes are already there. Then, subtract that answe from 12 to get how many you need.
Answer:
Count the units in total shown here:
There are 2 units both in the back and front.
So double of 2 means 4 units, there are 4 units on the back and front.
Now count the units between them:
There are 4 units across from them.
Add the units together:
4 + 4
= 8, there are 8 units in total shown in this figure.
But, we need to find how many more units should be added to these 8 units to get a result of 12 units altogether.
So, subtract the 8 units from the 12 units to get the remaining units you would need to add to 8 units to get 12.
12 - 8
= 4, you would need 4 more units so that this figure would have a volume of 12.

A. X = 1.4
B. X = 6.7
C. X = 10
D. X = 55
Answer:
D
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] (2x + 2) - [tex]\frac{1}{4}[/tex] (3x - 1) = 15
multiply through by 4 ( the LCM of 2 and 4 ) to clear the fractions
2(2x + 2) - (3x - 1) = 60 ← distribute parenthesis and simplify left side
4x + 4 - 3x + 1 = 60
x + 5 = 60 ( subtract 5 from both sides )
x = 55
