You can use the vertical angles theorem to find the value of x.
2x+84=5x
84=3x
x=28
Now, since <TSV and >PSV are linear pairs, you can add PSV and TSV. To do this, you have to find the value of PSV.
PSV=5x
x=28, so PSV = 5(28)
PSV=140°.
Now, find TSV.
180°-140°=40°
m<TSV=40°, or B.
3x + 2y = -26
4x - 5y = -4
To eliminate, we are going to cancel out the y
So multiply the first equation by 2.5, and you'll get
7.5x + 5y = -65
Add this equation to the second, and you'll get
11.5x = -69
Divide by 11.5 on both sides, and you get
x = -6
Now plug the -6 into the first equation, and you get
3(-6) + 2y = -26
Solve
-18 + 2y = -26
2y = -8
y = -4
Answer:
59 1/11 %
Step-by-step explanation:
13 chocolate and 9 vanilla = 22 total cupcakes
Percent chocolate = 13 chocolate / 22 total
=13/22
=.59090909
=59 1/11 %
Answer:
19 days
Step-by-step explanation:
The first day he saves 2.25.
The second day he has saved 2.25 + 2.25 or 2.25(2).
The third day he has saved 2.25 + 2.25 + 2.25 or 2.25(3)
This continues for x number of days so 2.25x.
If the video game costs 41.95 then set equal to 2.25x and solve.
2.25x = 41.95
x = 18.64
This rounds to 19.
