Answer:
Jessica makes $36 less than Kimmie
Step-by-step explanation:
Let
x -----> amount paid to Jessica
y ----> amount paid to Lauren
z ----> amount paid to Kimmie
we know that
------> equation A

-----> equation B

-----> equation C
substitute equation B and equation C in equation A and solve for y




<em>Find the value of x</em>

<em>Find the value of z</em>

therefore
The amount paid to Jessica was $24
The amount paid to Lauren was $36
The amount paid to Kimmie was $60
To find out how much less Jessica did than Kimmie, subtract the amount paid to Jessica from the amount paid to Kimmie.

therefore
Jessica makes $36 less than Kimmie
Answer:
A
Step-by-step explanation:
We can substract the wavength of the violet light to the wavelength of the red light:
(6.5 x 10^-7 m) - (4.0 x 10^-7 m) = 2.5 x 10^-7 m
The Answer is B. I hope this helped.
Chris and Jim must replace a <em>total</em> quantity of 17 tyres.
<h3>What is the minimum number of tyres to be replaced?</h3>
In this problem we must use an inequality of the form f(x) ≥ a, where f(x) is the difference between the number of tyres replaced by Jim and the number of tyres replaced by Chris:
(25/20) · x - x ≥ 3
(5/20) · x ≥ 3
x ≥ 12
Then, the <em>minimum</em> number of tyres to be replaced is n = 15 + 12 = 17 tyres.
