Answer: x=3
work cited:
128(x+1)=512
distribute 128 into parenthesis
128x+128=512
subtract 128 and move it to the other side of parenthesis
128x=384
lastly divide the 128 from the x to the 384
128x/128=384/128
x=3

Answer:

x=3

Step-by-step explanation:

So first do distributive property, which makes it 128x+128=512, then subtract 128 from both sides which makes it 128x=384, then divide by 128 on both sides and you get x=3.

alex spent 3/7 of his money he gave 1 /4 of the remainder to his sistet he haf $120 left how much money did he in the beginning

Sonbull [250]

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.
