Answer:
36 laps Ronnie swim during practice .
Step-by-step explanation:
Let us assume that the laps that Ronnie swims be x .
Let us assume that the laps that Jackie swims be y .
As given
For every 3 laps that Jackie swims, Ronnie swims 4 laps.
i.e
3 × laps that Ronnie swims = 4 × laps that Jackie swims
3 × x = 4 × y
3x = 4y
Equation becomes
x + y = 63
Thus by using 3x = 4y .
Thus
4x + 3x = 63 × 4
7x = 252
x = 36
Put the value of x in the equation x + y = 63
36 + y = 63
y = 63 - 36
y = 27
Therefore the 36 laps Ronnie swim during practice .
y = 23/(3 + x)
Step-by-step explanation:
This can be solved 6 ways depending on how many numbers u have
3024₅ = 3•5³ + 0•5² + 2•5¹ + 4•5⁰ = 389
Answer: 4.5p + 40 = 112
Step-by-step explanation:
Let p represent the number of pairs of shoes that Roger must sell in a day to meet his daily earnings goal.
Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes he sells in a day. This means that if he sells p shoes in a day, his total earnings for that day is expressed as
4.5p + 40
Since his daily earnings goal is $112, then the equation to determine how many pairs of shoes he must sell to meet his daily earnings goal is
4.5p + 40 = 112
