Rewrite as
= 24
Multiply both sides by 3 to isolate 2x².
2x² = 72
Divide both sides by 2 to isolate x².
x² = 36
Square root both sides to isolate x.
x = -6 or 6
-6 is smaller than 6.
The smallest solution is -6.
Answer:
D) 90 cupcakes and 20 cookies
Step-by-step explanation:
90(1.5) + 20(.75) = 135 + 50 = $185
90 + 20 is less than or equal to 120
185 is greater than 125
Why other options won't work:
A) 50(1.5) + 60(.75) = 75 + 12 [$87 is less than $125]
B) 60(1.5) + 40(.75) = 90 + 30 [$120 is less than $125]
C) 100 cupcakes + 30 cookies exceeds 120 treats
Recall your d = rt, distance = rate * time
the buses are traveling in opposite directions, but both are taking off at the same time
let's say bus A is going at 63mph and bus B is going at 62mph, so, we know their "r" rate for each
ok, after they had travelled for "t" time, they're both 187.5 miles apart, at that instant, bus A has been travelling for "t" hours and bus B has been also travelling for "t" hours as well
now, if bus A covered say "d" miles in those "t" hours, then bus B covered the slack from 187.5 and "d", or 187.5 - d
thus
solve for "t".
