There was a 20% decrease. To find the decrease, subtract the old number from the new number. (30-24=6) Then divide the decrease (6) by the original number and multiply the answer by 100. (6/30=0.2 0.2*100=20).
Answer:
b. $31.44
Step-by-step explanation:
The tank holds 11.75 gallons. Tim will need to get half of this amount to bring the tank back up to half full; this is
11.75/2 = 5.875
The gas costs $4.50 per gallon; this means the cost is
5.875(4.50) = 26.4375 ≈ 26.44.
There is also a $5 refueling charge; this makes the total cost
26.44+5 = 31.44
Answer:
(B) The inequality that represents this relationship is
Step-by-step explanation:
Let us assume the given number = x
⇒ 3 times the given number = 3 (x) = 3x
Square of the given number =
Now, According to the question:
The difference of (3 x) and 15 is no less than
⇒
or,
Hence, the given inequality is represented as
Answer:
g(q) =
Step-by-step explanation:
Given
- 7q + 12r = 3q - 4r
Rearrange making r the subject
Add 7q to both sides
12r = 10q - 4r ( add 4r to both sides )
16r = 10q ( divide both sides by 16 )
r = = , thus
g(q) =
