C.42 bc. $150x3=$450 then $6750-$450=$6300 divide that by $150 and you get 42.
It has to be the 2 and 3 because when you multiply fractions you use keep change flip for example 2/3 divided by 2/3 you keep the first fraction 2/3 you change division to multiplication and you flip the last fraction which will be 2/3x3/2
Answer:
3X+24=7X-4
3X-7X=-4-24
-4X=-28
X=-28/-4
X=7 ANS.
PROOF:
3*7+24=7*7-4
21+24=49-4
45=45
Step-by-step explanation:
Answer: the cost of a milkshake is $2.59
Step-by-step explanation:
Let x represent the cost of a banana split.
Let y represent the cost of a milkshake.
At the ice cream shop, one banana split and five milkshakes cost $16.24. This is expressed as
x + 5y = 16.24- - - - - - - - - - - - -1
If three banana splits and two milkshakes cost $15.05. This is expressed as
3x + 2y = 15.05- - - - - - - - - - - - -2
Multiplying equation 1 by 3 and equation 2 by 1, it becomes
3x + 15y = 48.72
3x + 2y = 15.05
Subtracting, it becomes
13y = 33.67
y = 33.67/13
y = 2.59
Substituting y = 2.59 into equation 1, it becomes
x + 5 × 2.59 = 16.24
x + 12.95 = 16.24
x = 16.24 - 12.95
x = 3.29
8 candles and 16 bars of soap.
You can solve this by setting up a system of equations.
x + y = 24
4x + 5y = 112
