First you are gonna drop the parenthesis. Then you are gonna combine -1 and +3 which gives you +2.
-7x-14=2x+13 What does x equal?
Answer: x = -3
Step-by-step explanation:
Given
-7x - 14 = 2x + 13
Subtract 2x on both sides
-7x - 14 - 2x = 2x + 13 - 2x
-9x - 14 = 13
Add 14 on both sides
-9x - 14 + 14 = 13 + 14
-9x = 27
Divide -9 on both sides
-9x / -9 = 27 / -9
[tex]\boxed {x = -3}[/tex]
Check:
Left-hand side = -7x - 14
= -7 (-3) - 14
= 21 - 14
= 7
Right-hand side = 2x + 13
= 2 (-3) + 13
= -6 + 13
= 7
7 = 7

The graph shows the number of appearances of hockey teams in the Stanley Cup Finals.
a. Write the ratio that compares the appearances made by the Rangers to the appearances made by the Canadiens in simplest form. Then explain its meaning
Answer:
Step-by-step explanation:
Important fact: much as I hate to admit it, in all professional sports, there is no team that has made as many appearances in the sports final as the Canadiens.
The ratio you want is 10/32 = 5/16.
The ratio means that for every 5 appearances the rangers made, the Canadiens made 16 appearances.

O M ZABC = 60°
OM ABC = 67°
OM ZABC = 120°
O M ABC = 127°
Answer:
∠ ABC = 127°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ABC is an exterior angle of the triangle , then
∠ ABC = ∠ BDC + ∠BCD = 60° + 67° = 127°
We know that we have a triangle and we want to find the value of its angle which will be given by 53°.
We know that the sum of all the interior angles of a triangle must equal 180 degrees, so we find then:
[tex]ABC=180[/tex]
Now making the sum of the angles already known and equating to 180, we find that:
[tex]180=67+60+x\\x=180-127\\x= 53[/tex]

Solve for X
2x+5=x-10
Answer:
x = -15
Step-by-step explanation:
Subtract x on both sides
x + 5 = -10
Subtract 5 on both sides
x = -15
Check work:
2(-15) + 5 = -15 - 10
-30 + 5 = -25
-25 = -25
35. The circumference of a circle is 67
inches. What is the area of the circle?
A=2
Answer:
B
Step-by-step explanation:
hopefully it makes sense and is visible:)
====================================================
Work Shown:
C = 2*pi*r .... circumference equation
6pi = 2pi*r .... replace C with the given circle perimeter
6 = 2r .... divide both sides by pi, they cancel
6/2 = r
3 = r
r = 3 ... is the radius
------------
A = pi*r^2 .... area of circle equation
A = pi*3^2
A = pi*9
A = 9pi .... which points to choice B as the final answer

MP3 player: 88%
Video game player: 92%
b.
MP3 player: 75 minutes
Video game player: 67 minutes
Step-by-step explanation:
a.
MP3 player
- Already has 40%
- Each 15 minutes additional 12%
--> An hour = (60/15)*12 = 48 (%)
--> After an hour charged = 40 + 48 = 88%
Video game player
- Already has 20%
- Each 10 minutes additional 12%
--> An hour = (60/10)*12 = 72 (%)
--> After an hour charged = 20 + 72 = 92 (%)
b. To charges 100 minutes:
MP3 player
100 = 40 + ((x/15*12)
--> x = 75 (minutes)
Video game player
100 = 20 + ((x/10*12)
--> x = 67 (minutes)

Answer:
6.3 cm
Step-by-step explanation:
The distance from each centimeter is divided into 10 parts. Point A starts at 0 and goes until right before 6.5. The big line between each whole number signifies that you are halfway through the centimeter. As you can see, point B is right before a big line, so can't be bigger than 6.5 nor equal. The only option that fits this is 6.3 cm
The answer is 6.3 cm

The sign shows distances from a rest stop to the exits for different towns along a straight section of
highway. The state department of transportation is planning to build a new exit to Freestone at the
midpoint of the exits for Roseville and Edgewood. When the new exit is built, what will be the distance
from the exit for Midtown to the exit for Freestone?
Exit for free stone
(35+51)/286/243miDistance from midtown to free stone
43-1726miThe distance from Midtown to Freestone is 26mi.
What is the distance?The Distance is defined as the product of the speed and time.
Given data as:
Exit for Midtown = 17 mi
Exit for Roseville = 35 mi
Exit for Edgewood = 51 mi
Exit for freestone = (35+51)/2
Exit for freestone = 86/2
Exit for freestone = 43mi
Distance from Midtown to Freestone = Exit for freestone - Exit for Midtown
Distance from Midtown to Freestone = 43 - 17
Distance from Midtown to Freestone = 26mi
Hence, the distance from Midtown to Freestone is 26mi.

also not sure if you wanted the values for n
edit:
7. n/2 = 16
8. 2n + 4 = 52
9. 2(n + 5) = 17
10. 3n - 12 = 5
Answer:
7. 32
8. 24
9. 3.5
10. 5.6
Step-by-step explanation:
7. write the equation: n/2=16. Cross multiply.
8. write the equation: 52= 4+2n. Move 4 to the other side and subtract from 52: 48= 2n. Divide both sides by 2.
9. write the equation: 2(5+n)=17. Use the distributive property. Move 10 to the other side and subtract from 17: 2n=7. Divide both sides by 2.
10. write the equation 3n-12=5. move -12 over and add to 5: 3n=17. Divide both sides by 3.
