Answer:
$50.75
Step-by-step explanation:
There are 2 half hours in 1 hour. Since he needs the kayak for 3 half hours, you can multiply the $14.50 by 3. You still need to get the extra 15 minutes. Since a half hour is 30 minutes, and 30 divided by 2 is 15, you can divide 14.5 by 2 to get 7.25. 7.25+ (14.5×3)=15.75.
Answer:
7 - 2 / x = 4 + 10 / x
or , 7 - 4 = 10 / x + 2 / x
or , 3 = 12 / x
or , x = 12 / 3
Therefore , x = 4
Answer:
-3x+6
Step-by-step explanation:
Again, you multiply -3 times x and you get -3x, then you multiply -3 times -6 and since you are multiplying two negative numbers the result becomes positive so you get +6. Result = -3x+6

Answer: a. x=4 b. x=17.5
Step-by-step explanation:
a. 5x/2+1=11
subtract 1 from both sides : 5x/2=10
multiply both sides by 2 : 5x=20
divide both sides by 4 : x=4
b. 2x/7-3=2
add 3 to both sides : 2x/7=5
multiply both sides by 7 : 2x=35
divide both sides by 2 : x=17.5
