Answer:
Step-by-step explanation:
To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)
5x + 2y = 7
6x –2y = 4
Why is this multiplication allowed? (1 point)
Because the entire equation was multiplied by the same number, the equation remains the same.
What variable will be eliminated when the equations are combined after the multiplication? (1 point)
The Y variable
Next, add the equations together. Your answer should be a single equation with one variable. (1 point)
11x = 11
Solve the equation for x. (1 point)
X = 1
What is the solution to the system of equations? (1 point)
X = 1 and Y = 1 so the answer is (1, 1)
(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)

How many 1/8 tps can go into 1/8 cup?
Answer:
6 tps
Step-by-step explanation:
3 tsp = 1 tablespoons
16 table spoons = 1 cup
therefore 48 teaspoons = 1 cup
therefore 1/8th cup =6 teaspoons
Answer:
(1/8) cup = 6 U. S. teaspoons
Step-by-step explanation:
Do a quick Internet search. Type '1 cup = teaspoons" into the address line as tho' you were doing a search. Result: 1 cup = 48 U. S. teaspoons.
We want to know the teaspoon equivalent of 1/8 cup. To get this, multiply both sides of the above equation by 1/8:
(1/8) cup = (1/8)(48 U. S. teaspoons), or (1/8) cup = 6 U. S. teaspoons.

Two cars are traveling down the highway at the same speed. If the first car increases its speed by 10 kilometers per hour, and the second car decreases its speed by 10 kilometers per hour, then the first car will travel the same distance in two hours that the second car travels in three hours. What is the original speed of the cars?
Answer:
50mph
Step-by-step explanation:
Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.
A = 50+10
b = 50-10
A = 60
B = 40
A2 = 120
B3 = 120
120 = 120
Answer
120km
Step-by-step explanation:
let s = the original speed
Write a distance equation; dist = time * speed
3(s-10) = 2(s+10)
3s - 30 = 2s + 20
3s - 2s = 20 + 30
s = 50 km/hr is the original speed
confirm this, find the distances
3(50-10) = 120 km
2(50+10) = 120 km

N'(-10,-15) is the image of N after a dilation with a scale factor of 5/4, centered at the origin. What are the coordinates of N?
When the point N is dilated, the coordinate of N changes to N'
The coordinate of point N is (8,12)
How to determine the coordinate of NThe given parameters are:
N' = (10,15)
k = 5/4
To calculate the coordinate of N, we make use of:
N * k = N'
So, we have:
N * 5/4 = (10,15)
Multiply both sides by 4
N * 5 = (40,60)
Divide both sides by 5
N = (8,12)
Hence, the coordinate of point N is (8,12)
