Sometimes
Step-by-step explanation:
Three line sometimes intersect
The answer is b because It’s right
First combine the like terms 5w and -4w to get just w.
so now the problem looks like:
w + 4= 14
subtract 4 from each side now. and you get the answer:
w = 10
Step-by-step explanation:
x = number of $50 bills
y = number of $100 bills
x + y = 20
50x + 100y + 500 = 100x + 50y
50y + 500 = 50x
y + 10 = x
now we use that in the first equation :
y + 10 + y = 20
2y = 10
y = 5
x = y + 10 = 5 + 10 = 15
so, he has 15 $50 bills and 5 $100 bills = $750 + $500 = $1250 in his wallet
Answer:
101/140
Step-by-step explanation:
<u>Solving in steps:</u>
- -6/15 * 4/7 - (-7)/20 * 4/7 + 3/4 =
- - 2/5 * 4/7 + 7/20 * 4/7 + 3/4 =
- - 8/35 + 7/35 + 3/4 =
- -1/35 + 3*35/4*35 =
- -4/140 + 105/140 =
- 101/140
