Answer:
$5
Step-by-step explanation:
Let the variables A, B, C, D represent a sack of apples, a bunch of bananas, a cantaloupe, and a carton of dates, respectively. Then the problem statement gives rise to 3 equations:
A +B +C +D = 20
D = 2A
C = A -B
Substituting the last two equations into the first gives ...
A +B + (A -B) +2A = 20
4A = 20 . . . simplify
A = 5 . . . . . divide by 4
Substituting this into the last equation, we have ...
C = 5 -B
B + C = 5 . . . . add B
The cost to purchase a bunch of bananas and a cantaloupe is $5.
To solve this problem
Let X be pounds of rose petals needed.
ATQ
0.875 pounds of rose petals are in 1 bottle.
So, 0.875 / 1 = X / 86
( because we have to find how many petals {in pounds}are there in 86 perfume bottles )
cross muliplying both side.
0.875 * 86 = X
75.25 = X
So, there are 75.25 pounds of petals in 86 perfume bottles.
Answer: 5 (estimate)
Step-by-step explanation:
x - 17 4/5 = -13 1/5
Estimate: x - 18 = -13
x - 18 + 18 = -13 + 18
x = 5
actual answer without estimating using exact numbers is 4 3/5 (so estimate is reasonable)
