Explanation:
It is possible to write the ratio as 1/p=x/5. xp = 5 is the result of solving for the variable x, where x=5/p. Lynn can therefore type five pages per minute.
Explanation:
The ratio 22/132=15/x can be used to estimate Kim's earnings for the upcoming week. x = 90 is obtained by solving for x. She will therefore earn $90 the next week if she puts in 15 hours.
Explanation:
In an hour, Jessica can paint a quarter of the home. In an hour, Johnny can paint a sixth of the same house. When they collaborate, the following equation can be used to calculate how long it will take them to paint the house: 1/4 x+1/6 x=1. 5/12 x=1 is obtained by solving for x, where x = 2.4 hours, or 2 hours and 24 minutes.
Explanation:
The equation 80+(80*0.0825) may be used to indicate the price you will pay for the book. Consequently, the cost of the book is $86.60. You will receive $13.40 in change, which is the difference between $100 and $86.60.
Explanation:
By dividing both sides of the equation r=5z by 5, it is possible to find the value of z. This results in r/5=z. The result of changing the variable z in the equation 15z=3y to r/5 is 15(r/5)=3y. By finding y, we get r = y.
Explanation:
40 pen packets and 3 sets of staplers are required. Thus, equation 40(2.35) + 3 can be used to describe the whole cost (12.95). It costs $132.85 in total.
Explanation:
You can write the price you paid for the car as $3,000 + 6($225), which comes to $4,350.
