Answer 5

Addition Property of Equality

Answer 6

To solve the equation 2f5−85+2f=8, we need to simplify and isolate the variable f.

First, we combine like terms on the left side of the equation:
2f + 2f = 4f
-85 + 5 = -80

So the equation becomes:
4f - 80 = 8

Next, we isolate the variable f by adding 80 to both sides of the equation:
4f - 80 + 80 = 8 + 80
4f = 88

Finally, we solve for f by dividing both sides of the equation by 4:
4f/4 = 88/4
f = 22

Therefore, the solution to the equation 2f5−85+2f=8 is f = 22.

Answer 7

The equation is 23(6m+9)−6=4m. To determine the number of solutions, we need to simplify and solve for m.

First, we distribute the 23 to the terms inside the parentheses:
138m + 207 - 6 = 4m

Next, we combine like terms:
138m + 201 = 4m

To isolate the variable m, we subtract 4m from both sides of the equation:
138m - 4m + 201 = 4m - 4m
134m + 201 = 0

At this point, it is evident that there is no value of m that satisfies the equation.

Therefore, the equation 23(6m+9)−6=4m has no solution.

Answer 8

The pair of linear equations that have the same solution set is:

3(m+1)=10 and 6n+3=6−n

Answer 9

To determine who is correct about the linear equations, let's analyze each equation:

Equation A: 3(4−5h)−7=−12+2h
Equation B: 2(p−3)−1=6p+142
Equation C: 23v−3+83=−1

We can simplify each equation to find their solution sets:

Equation A:
12 - 15h - 7 = -12 + 2h
5h + 5 = 2h - 5
3h = -10
h = -10/3

Equation B:
2p - 6 - 1 = 6p + 142
2p - 7 = 6p + 142
-4p = 149
p = -149/4

Equation C:
23v - 3 + 83 = -1
23v + 80 = -1
23v = -81
v = -81/23

From the solutions obtained, we can see that Equation A and Equation B have different solutions.

Tamara is incorrect.

Similarly, Equation B and Equation C also have different solutions.

Payton is incorrect.

Krish's statement cannot be confirmed as the solutions obtained for the equations are different.

Haruki's statement is correct. None of the equations have the same solution.

Therefore, Haruki is correct about the linear equations.
