Answer:
12n+9=93
solve for n
12n=93-9
n=84/12
n=7
therefore, Mr. copper bought 7 tickets.
Answer:
9/4
Step-by-step explanation:
Hmm, one way is this
there's 500 times 0.10 or 50 grams of salt in the water
if we want to make 50 grams=4% of everything, how much water do we need to add
50=4% of all
50=0.04 of all
divide both sides by 0.04
1250=all
so
500+what=1250
minus 500 both sides
what=750
750 grams of water
We need to find how many times 1/16 goes into 7/8. So, divide 7/8 by 1/16:
(7/8) / (1/16)
= (7/8) x (16/1)
= (7/8) x 16
= 7 x 16 / 8
= 7 x 2
= 14
The answer is 14.
(Intuitively, since 1/16 goes into 1/8 two times, it goes into 7/8 fourteen times.)
Answer:
B. -3 and 2/3
Step-by-step explanation:
One way to see the constants is to set the variables to zero. What's left is ...
-3 + 2/3
These are the constants in the expression.
