Answer:
54
Step-by-step explanation:
to evaluate substitute b = 18 into 3b
3b = 3 × 18 = 54
Initial fee: $25
Per hour fee: $7
Your budget: $60
x = # of hours you can rent the surfboard
$25 + $7x ≤ $60
Subtract $25 from both sides.
$7x ≤ $35
Divide both sides by $7
x ≤ 5
You can rent the surfboard for less than or equal to 5 hours.
Answer:
x=-4/3
Step-by-step explanation:
3x-12=12x
3x-12x=12
-9/-3=12/-3
then -3 cancels
3x/3=-4/3
then 3 cancels 3
so x=-4/3
Answer:
Choices A, C, E
Step-by-step explanation:
The prices are proportional, so divide any price by the corresponding number of pounds to find the unit cost.
$1.47/(3 lb) = $0.49/lb
The unit cost is $0.49 per lb.
Now we look in the choices to see which choice has a unit price of $0.49/lb.
We divide each price by its number of pounds to fund each unit cost. Every choice with a unit cost of $0.49/lb is an answer.
A $0.98/(2 lb) = $0.49/lb Choice A works
B $4.45/(7 lb) = $0.64/lb Choice B does not work
C $2.94/(6 lb) = $0.49/lb Choice C works
D $0.54/(1 lb) = $0.54/lb Choice D does not work
E $3.92/(8 lb) = $0.49/lb Choice E works
