They are vertical angles so you need to make the following equal
7y=5y+36 and 3x-21=2x+4
Solve for y and then x
7y=5y+36
Subtract 5y on both sides to get
2y=36
Then divide by 2 on both sides to Get y=18
For 3x-21=2x+4,
Subtract 2x on both sides to obtain
x-21=4
Then add 21 to both sides to get
x=25
Hope this helps!! Mark as brainliest!!!
Answer:
2a+15 = 125(being alternate angle)
or,2a = 125-15
or,2a = 110
or,a = 110÷2
,a = 55
again,2a+15+b+30=180(Being co-interior angle)
or,2×55+15+b+30=180
or,110+15+30+b=180
or,155+b=180
or,b=180-155
Therfore,b=25
Here is the equation:
Leave the variable alone by subtracting 2 from both sides:
The new equation becomes:
Leave the variable alone(again) by dividing both sides by 2:
Simplify and it becomes:
Step-by-step explanation:
A = P*e*r*t
P = 1,000
e = 2.71828
r = 0.09
t = 1
A = (1,000)*(2.71828)*(0.09)*(1)
A = 244.65
Put 3x in for y, so the equation will be 3x=2x-7. Then solve. once you find “x”, plug it back into one of the original equations. And then you have x and y
