Answer:
y = 9
Step-by-step explanation:
to solve this equation, you first have to divide:
14 * y = 126
/14 /14
y = 9
and there is the answer. If you need to prove that y = 9, just input it into the equation.
14 * 9 = 126
126 = 126
Answer: He made $90 last week.
Assumption :
Let, Luis made $X last week.
He made $72 this week which is 80% of $X that he made last week
⇒ X * 80% = 72
⇒ X * 80/100 = 72
⇒ X = (72 * 100)/80
⇒ X = 90
Therefore, he made $90 last week.
To remember :
While solving this type of problems, be careful to understand which one of last time and current time is not given; just assume that one and input other conditions, the problem will be solved.
850. If there is 17 red beads for every 150 beads Then you would divide 7500 by 150 and you get 50. Then multiply 50 with 17 and your answer is 850 red beads. 7500/150=50. 50 x 17= 850.
16
x * 3 = 48
so divide 48 by 3
which is 16 so x = 16
It has already given you the answer.
