Answers

Answer 1

Answer:

x=-5

Step-by-step explanation:

-3x+25=40

      -25   -25

-3x=15

  /-3    /-3

x=-5

Hope I helped!

Answer 2

Answer:

x= -5

Step-by-step explanation:

1. Subtract both sides by 25.

[tex] - 3x + 25 - 25 = 40 - 25[/tex]

2. Divide both sides by -3

[tex] - 3 x= 15[/tex]

[tex] \frac{ - 3x}{ - 3} = \frac{15}{ - 3} [/tex]

3. Simplify

[tex]x = - 5[/tex]

Lisa and Marie are both on the track team. During practice, Lisa ran 10 laps around
the track in 18 minutes. Marie ran 8 laps around the track in 14 minutes. Who ran at a
faster rate? If each runner continues at her same pace, how long would it take each
one to run 15 laps?

Answers

Answer:

Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.

Step-by-step explanation:

18 ÷ 10 = 1.8 (Lisa's rate)

14 ÷ 8 = 1.75 (Marie's rate)

1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)

1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)

How do I find the value of y?

Answers

Answer:

y = 27

Step-by-step explanation:

line segment BA and CD are congruent, turn them into an equation

3y - 59 = y - 5

subtract 1y from both sides, you get 2y - 59 = -5

then, add 59 to both sides and the equation is now 2y = 54

divide each side by 2 and you get the value of y (y = 27)

What is the solution to this system of equations?
X+ 2y = 4
2x-2y = 5
O (3.-53
0
(3.)
no solution
infinitely many solutions

Answers

Answer:

X+2y=4

4+2y=x

2(2+y)=x

2x-2y=5

2(x-y)=5

x-y=5/2

Answer:

(x, y) = (3, 1/2)

Step-by-step explanation:

x + 2y = 4

2x - 2y = 5

There is more than one way to do this. I will do it by substitution.

From the first equation, x + 2y = 4, so x = (-2y) + 4

Now, in the second equation, I will replace x with (-2y + 4)

2(-2y + 4) - 2y = 5

-4y + 8 -2y = 5

-6y + 8 = 5

-6y = -3

6y = 3

y = 3/6

--------------------------------->  y = 1/2, one part of the answer

Now I can go back to the first equation, and relpace 'y' with 1/2

x + 2(1/2) = 4

x + 1 = 4

----------------------------------->  x = 3, the other part of the answer

So now we believe the solution is (x, y) = (3, 1/2)

Now check the answer, back in the original equations!!

------> In the first equation, we would have 3 + 2(1/2) = 4.

                                                                       3 + 1 = 4

                                                                       That is true

-------> In the second equation, we would have 2(3) - 2(1/2) = 5

                                                                                6 - 1 = 5

                                                                          That is true

Our answer is found and checked.

So:

[tex]3 + b + 2 = 3 + (b + 2)[/tex]

When the positions of 2 and b are interchanged, we have:
