Answer:
78 laundries
$0.25
Step-by-step explanation:
If the box contains 195 scoops and at once he uses 2 1/2 you have to divide 195 by 2 1/2 and you get 78.
How much is he paying for each load? you have to find the unit rate. The box costs $19.99 he can do 78 laundries at once so you divide the money by the quantity or in other words $19.99 by 78 and get 0.2562820512820513, since we are talking about money we use only the firs two decimals, so he pays $0.25 per load of laundry.
Answer:
82, 84
Step-by-step explanation:
-9/15y+3/21=5/15y-14/21
Move 5/15y to the other side. Sign changes from +5/15y to -5/15y
-9/15y-5/15y+3/21=5/15y-5/15y-14/21
-14/15y+3/21=-14/21
Move 3/21 to the other side. Sign changes from +3/21 to -3/21.
-14/15y+3/21-3/21=-14/21-3/21
-14/15y=-14/21-3/21
-14/21-3/21=-17/21
-14/15y=-17/21
Multiply both sides by -15/14
-14/15y(-15/14)
Cross out 15 and 15, divide by 15 then becomes 1
Cross out 14 and 14, divide by 14 then becomes 1
1*1*y=y
-17/21*-15/14
Cross out 15 and 21 , divide by 3. 15/3=2, 21/3=7
17/7*5/14=85/98
Answer: c. y=85/98
