Answer:
C) 24
Step-by-step explanation:
Set x equal to the number of cousins Juan has:
5/8 = 15/x
Cross-multiply: 5x = 15 × 8
5x = 120
x = 24
Answer:
8
Step-by-step explanation:
the unknown can NEVER be negative
so you wont see an answer like
-b= 7, -a=98; -k= -9
so,
-x= -8 (change their positions so that the unknown, x, is positive)
x=8
Answer:
$1343
Step-by-step explanation:
The equation would be
x= 1580 (1-0.15)
x represents how much he actually pays.
1-0.15=0.85.
1580×0.85=1343
692.08 : 21.1
Divide both sides by 21.1
32.8 :1
32.8ft per second
Hope this helps :)
