Casey is deciding which of two landscapers to hire. Each landscaper charges an hourly rate plus a fee for each job.Casey correctly wrote and solved a system of linear equations by substitution. In his work, he substituted an expression for one variable and solved for the other. This resulted in the equation 5 = 20. What can Casey conclude?

One landscaper charges $20 for 5 hours of work.
One landscaper’s hourly rate is $15 lower than the other landscaper’s.
Both landscapers charge the same hourly rate and the same fee per job.
Both landscapers charge the same hourly rate, but not the same fee per job.

Answers

What Casey can conclude is D. Both landscapers charge the same hourly rate, but not the same fee per job.

What Casey can conclude based on the given scenario

Both landscapers will charge the same hourly rate because we were told they each charges an hourly rate including a fee for each job.

Their fees per job cannot be the same because Casey substituted an expression for one variable while he solved for the other.

Therefore the correct option is D.

3=?
What does 3 equal?

Answers

$8x=56$
$x=7$

$7x=42$
$x=6$

$6x=30$
$x=5$

$5x=20$
$x=4$

From these numbers, you can see there is a pattern. You have to multiply your first number by another number that decreases by one each time.
Knowing this, you can solve for what 3 equals.

$3(4-1)$
$3(3)$
$9$

$3=9$

C=25. S=a. B=4c-s2. What would b equal to

Answers

Answer: B = 100 - a^2

Solution:

Step 1: Substitute all the values that are given in the equation

that would be C = 25 and S = a

Step 2: when substituted the equation would be

B = 4 (25) - (a)^2

B = 100 - a^2 Would be the answer

Note: if there was a numerical value to s then the answer would be a number but since s=a so the answer has variable too.

How could you estimate the number of M&M's in a jar? (check all that apply)a
count them
b
count a sample and estimate the number of times it would take to fill using the sample
c
the area of the jar divided by the area of an M&M
d
measure the height of the jar
e
the volume of the jar divided by the volume an M&M

Answers

i think its b or e because i rember doing these in school and what i would do is i would look at the jar and one of the thing we had to guess and then i would guess or e because you could look at lenght width and height

Final answer:

There are multiple ways to estimate the number of M&M's in a jar, including counting them, counting a sample, and calculating the volume ratio.

Explanation:

Estimating the number of M&M's in a jar can be done using multiple methods. First, you can count them one by one, which is time-consuming but accurate. Second, you can count a sample of M&M's and estimate the number of times it would take to fill the jar using the sample. Lastly, you can calculate the volume of the jar divided by the volume an M&M to estimate the number of M&M's in the jar.
