The time it will take Carley's dad to mow the lawn is 3.3 hours.
<h3>What is rate?</h3>
Rate is the ratio between two related quantities in different units. Therefore,
The rate Carley do the lawn = 1 / 5
When they work together they do it the 1 / 2 rate.
Therefore,
let
the hours it takes Carley dad = x hours . Therefore,
1 / 5 + 1 / x = 1 / 2
x + 5/ 5x = 1 / 2
cross multiply
2(x + 5) = 5x
2x + 10 = 5x
10 = 5x - 2x
10 = 3x
x = 10 / 3
x = 3.3 hours

Answer:
5
Step-by-step explanation:
we just figure it out by making an equation
3x = 6th graders
4x = 7th graders
35 = total
so
3x + 4x = 35
7x = 35
x = 5
sooooo
3(5)= 15 = 6th graders
4(5) = 20 = 7th graders
SOOOO
20-15 = 5
1) Draw the triangles JKL and J'K'L' in a same coordinate system.
When I did that, I realize the if you translate the triangle JKL 1 unit left and then you reflects the image across the x-axys you get the you get the triangle J'K'L'.
So, select the boxes in that same order:
1) translation 1 unit left
2) reflection across the x - axis.
2) The answer ot the second question is line r.
That is called the line of reflection because if you reflect the figures through it you will have the same figure.
First, write the rate as a decimal by moving the decimal point two places to the left from the percent.
r = 5% = 0.05
C = p + rp
C = 30.99 + 0.05 * 30.99
C = 30.99 + 1.55
C = 32.54
Answer: The total cost is $32.54
