Answer:
G
Step-by-step explanation:
Red marble probably currently: 12/32 = 3/8
Guess and check (using the multiple choice answers):
F: 12 + 13 / 32 + 13 = 25/45 = 5/6; does not equal 3/5
G: 12 + 18 / 32 + 18 = 30/50 = 3/5; does equal 3/5
H: 12 + 28 / 32 + 28 = 40/60 = 2/3; does not equal 3/5
J: 12 + 32 / 32 + 32 = 44/64 = 11/16; does not equal 3/5
K: 12 + 40 / 32 + 40 = 52/72 = 13/18; does not equal 3/5
Answer:
11 4-passenger cars
Step-by-step explanation:
let 'x' represent the number of 4-passenger cars,then 'x-3' represent the number of 6-passenger cars.
92=4x+6(x-3)
92=4x+6x-18
92=10x-18
92+18=10x
110=10x
x=110/10
x=11
Therefore there are 11 4-passenger cars
148, 6-1.75=5.25, then.... 625/5.25& round up.... its 148.
Answer:
They will make $252
Step-by-step explanation:
We can use proportions to solve this problem. Put the money over the hours.
$357 x dollars
------------ = -----------
17 hours 12 hours
Using cross products
357*12 = 17x
Divide each side by 17
357*12/17 = 17x/17
252 =x
4x + 9 - (10/(3x)) I favored the x^2 then expanded and simplified each rational term
