I would say it would be 55 and if this question.If you get the answer incorrect my apologies
Step-by-step explanation:
40 + y + y + 30 = 180
2y + 70 = 180
2y + 70 (-70) = 180 (-70)
2y = 180 - 70
2y = 1102y/2 = 110/2
y = 110/2
y = 55

Answer:
r=4
Step-by-step explanation:
-4 (r+2) =4 (2-2r)
Divide each side by 4
-4/4 (r+2) =4/4 (2-2r)
-(r+2) = (2-2r)
Distribute
-r-2 = 2-2r
Add 2r to each side
-r+2r -2 = 2-2r+2r
r-2 =2
Add 2 to each side
r-2+2 =2+2
r=4
Check
-4 (r+2) =4 (2-2r)
-4 (4+2) =4(2-2*4)
-4(6) =4(2-8)
-24 = 4(-6)
-24 = -24
This checks
Let his total money be x.
He spent (3/7)*x of his money.
He gave 1/4(x-3/7x) to his sister.
which is : (1/4)*(4/7)*x = (1/7)*x
Now,
How much money he have in the beginning =
(3/7)*x+(1/7)*x+120=x
(4/7)*x+120=x
120=x-(4/7)*x
120=(3/7)*x
x=120*7/3 [cross multiplication]
x=280.
So, Alex had $280 in the beginning.
