Step-by-step explanation:
Given a system of two equations in Two variable, replacing one equation by the sum of that equation and multiple of the other produces a system with the same solution. Show why this is true by solving the system of equations given. Justify the reason for each step. Use addition property of equality and multiplication property of equally in your answers.
1. To solve the system using elimination, First multiply the bottom equation by two. Write the new system of equations.
5x+2y=7
2. Why is this multiplication allowed?
3. What variable will be eliminated when the equations are combined after the multiplication?
4. Next, add the equations tighter. Your answer should be a single equation with one variable.
5. Why can you add the equations
6. Solve the equations for x
7. Substitute x back into one of the equations solve for y
8. What is the solution to the system of the equations?
Please I need this in 24 hours
Answer:
5x + 2y = 7
3x � y = 2
multiply the second equation by 2 and leave the first equation as is to get:
5x + 2y = 7
6x � 2y = 4
add the second equation to the first equation to get:
11x = 11
divide both sides of that equation by 11 to get:
x = 1
replace x with 11 in the first original equation to get:
5x + 2y = 7 becomes 5 + 2y = 7
solve for y to get y = 1
your solution is x = 1 and y = 1
confirm by replacing x and y with 1 and 1 in both original equations to get:
5x + 2y = 7 becomes 5 + 2 = 7 which is true.
3x � y = 2 becomes 3 - 1 = 2 which is true.

Answer:
A
A
Step-by-step explanation:
8) because of the rules of angles we know that all angles found on a line are equal to 180 degrees, and all angles opposite one another are equal. because of this A is not possible. 90 and 40 do not add up to 180 degrees, and are not equivalent to each other.
9) using the same rules as above, we know that the two angles have to add up to 180 degrees (they can't be equal this time). A is not possible.
Joanna is driving 185 miles to visit her family. She drives 68 miles in the morning, stops for lunch, and then drives the rest of the distance. How many miles did she drive after lunch?
Use the variable m to represent the number of miles she drove after lunch.
Which equation represents this situation and its solution?
m + 68 = 185; m = 117
68m = 185; m = 17
m + 185 = 68; m = 117
185m = 68; m = 17
Answer:
The equation represents this situation and its solution are m + 68 = 185; m = 117 ⇒ A
Step-by-step explanation:
Let us solve the question
∵ Joanna is driving 185 miles to visit her family
∴ The total distance she is driving = 185 miles
∵ She drives 68 miles in the morning
∴ d[tex]_{M}[/tex] = 68 miles
∵ She stops for lunch and then drives the rest of the distance
∵ m represents the number of miles she drove after lunch
∴ d[tex]_{L}[/tex] = m miles
∵ d[tex]_{L}[/tex] + d[tex]_{M}[/tex] = the total distance she is driving
∴ m + 68 = the total distance she is driving
∵ The total distance she is driving = 185 miles
∴ m + 68 = 185
∴ The equation represents this situation is m + 68 = 185
→ To solve the equation subtract 68 from both sides
∵ 68 - 68 + m = 185 - 68
∴ m = 117 miles
∴ The solution is m = 117

A ladder rests 22 feet up the side of a building. If the base of the ladder is 20 feet away from the building, how tall is the ladder to the nearest hundredth?
Answer:
Length of ladder =L =15
Distance from wall = D =9
Height on wall = H =??
Pythagoras equation L*L = D*D + H*H
15×15= (9×9) + H×H
225-81 = 144 =HxH
H= 12 feet.

The required percentage that Cortney got correct on the test will be; 85.33%.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
We have been given that Cortney got 64 out of 75 correct on a test.
We Need to determine the best estimate of the percentage Courtney got correct.
Here,
The Total question = 75
The correct question = 64
Then Percentage = 64 / 75 × 100
Percentage = 85.33%
Thus, the required percentage that Cortney got correct on the test will be; 85.33%.

8-(36/9)+99-(6x7)
8-4+99-42
4+57
Answer:
11
Step-by-step explanation:
For this, we need to follow PEMDAS (Parenthesis, exponent, multiply/divide, add/subtract). First, we do the parenthesis, this gets us 8 - 4 + 49 - 42. Since this is all addition/subtraction, we do it from left to right. 8-4 is 4. Now our equation is 4 + 49 - 42. 4 + 49 is 53. Now our equation is 53 - 42. That is 11. That means our answer is 11.
All of the following represent the same function except _____.
y = x - 1
{(0, 1), (2, 3), (4, 5), (7, 8)}
x y
1 0
3 2
5 4
8 7
Answer: {(0, 1), (2, 3), (4, 5), (7, 8)}
Step-by-step explanation:
For the function: y = x - 1 (y is one less than x)
If x =1 , y= 0
if x= 3 . y= 2
If x = 5 , y= 4
If x= 8 , y= 7
So it is same as
x y
1 0
3 2
5 4
8 7
But different from {(0, 1), (2, 3), (4, 5), (7, 8)} [here x is 1 less than y]
So, the complete statement would be : All of the following represent the same function except {(0, 1), (2, 3), (4, 5), (7, 8)} .
What is the probability of spinning an odd number
