Rocco bought a soft drink for three dollars and six candy bars, He spent a total of twenty one dollars. How
Sophie [7]

Answer:

x=3

Step-by-step explanation:

The equation will be 3+6x=21 since we know that the soft drink costs 3 dollars and he bought 6 candy bars(6 times x or 6x). We also know that the total cost for this merchandise is 21 dollars. Now you solve the equation! First subtract 3 from both sides(since the inverse for addition is subtraction we SUBTRACT 3 from bothe sides). You are left with 6x=21-3 or 6x=18. Now you divide Each side by 6(because the inverse operation of multiplication is division). You have the answer! x=18/6 or x=3! Hope it helped!!

olya-2409 [2.1K]
The changing rate of the amount of water in the watering can is a constant rate of 0.15 gallon per minute. 

The initial volume of water in the can at time = 0 is 5 gallons

The function will be a linear function in the form of y=ax+b where 
y is the volume of water in the can after x minutes
a is the changing rate
b is the initial volume when time is 0

Substitute all the values into the form we have

y=0.15x+5

15 less than 2 times a number is the same as 7 more than half of the number. what is the number?
romanna [79]

Answer:

x = 14 and 2/3

Step-by-step explanation:

Make an equation where x is the number.

2x - 15 = 7 + 1/2x

Then, solve the equation.

multiply both sides by 2 to get rid of the fraction

4x - 30 = 14 + x

subtract x from both sides

3x - 30 = 14

add 30 to both sides

3x = 44

divide both sides by 3

x = 14 and 2/3
