Eli is deciding between two landscaping companies for his place of business. Company A charges $25 per hour and a $300 equipment fee. Company B charges $50 per hour and a $125 equipment fee. Let AA represent the amount Company A would charge for tt hours of landscaping, and let BB represent the amount Company B would charge for tt hours of landscaping. Write an equation for each situation, in terms of t,t, and determine which company would be cheaper if Eli needs 5 hours of landscaping.
Answer:
Company B will charge cheaper in 5 hours
Step-by-step explanation:
Step one:
Given data
Company A
charges $25 per hour and a $300 equipment fee
let the total be
A= 300+25t---------------1
Company B
charges $50 per hour and a $125 equipment fee.
let the total be
A= 125+50t---------------2
put t = 5 in the two expressions above
A= 300+25t---------------1
A= 300+25*5
A=300+125
A=$425
B= 125+50t---------------2
B= 125+50*5
B=125+250
B=$375
Answer:
A = 25t + 300 B = 50t + 125
company B is $50 cheaper than company A for 5 hours of landscaping

Answer:
1) Actual cost was $5,762.50
2) Joe's birthday is on January 1st.
Step-by-step explanation:
1) To find this, since we know they were wrong by an identical amount and one was over and the other was under, we can average the cost to find the difference between the amounts. Then we can add that difference to the lower (or subtract it from the higher) amount:
6950 - 4575 = 2375
2375 / 2 = 1187.50
4575 + 1187.50 = $5,762.50
2) Joe could turn 21 on January 1st, but was 20 on December 31st. Next year Joe would turn 22 on January 1st.
I hope this helps!

A baseball team batted 250 times during the season. During the season they got 120 hits, 60 strikeouts, 50 flyouts and 20 groundouts. What percent of the time that they batted did they make an out?
Answer: 52%
Step-by-step explanation:
The team batted 250 times. In that time, they got 60 strikeouts, 50 flyouts and 20 groundouts.
The total number of out they got was therefore:
= 60 + 50 + 20
= 130 outs
The percent of the time they got outs out of the total is:
= 130/250
= 52%
The temperature was 54° at 7:00am. At 3:00pm on the same day, the temperature
was 82°. What is the rate of change in temperature during this time? Hint: When
finding the difference in time, don't forget that 3:00pm could also be written as
15:00 (to figure out the difference in hours).
a) 3.25° per hour
b) 3.1° per hour
c) 2.8° per hour
d) 3.5° per hour
Answer:
3.5
Step-by-step explanation:
what you would do is from 7am to 3pm its 8 hours. then you would do 82 degrees - 54 degrees and you would get 28 degrees. ok then you would do 28 degrees divided by the 8 hours and you would get 3.5 degrees per hour.
hope this helps.
I'm not sure what AAS,SAS,SSS,ASA mean .how do I solve this?
Answer:
AAS is an acronym for Angle-Angle-Side. It basically means that if two angles and a nonincluded side of one triangle are congruent to two angles and the corresponding nonincluded side of a second triangle, then the two triangles are congruent. SAS is an acronym for Side-Angle-Side. It means that if two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle, then the two triangles are congruent. SSS is an acronym for Side-Side-Side. It means that if three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent. ASA is an acronym for Angle-Side-Angle. It means that if two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent.
In the problem, we know that the corresponding sides of both triangles are congruent to each other, so those would be given. The third side of each triangle would also be congruent because of reflexive property. Reflexive property means that the two triangles share a line segment. So, the answer would be SSS.

Convert -4x+y=5 to slop intercept form
Answer: -4x + y = 5 in slope intercept form is 4x + 5
Answer: y= 4x + 5
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y = mx + b
Rewrite in slope-intercept form.
Add 4x to both sides of the equation.
y = 5 + 4x
Reorder 5 and 4x.
y= 4x + 5

The perimeter of a rectangle is 28 inches. The length is 6 less than 3 times the width. What is the length of the rectangle?
Answer: The length is 9 inches.
Step-by-step explanation:
L = 3w - 6 (the length is 6 less than 3 times the width).28 = 2(3w - 6) + 2w (plug in width and length --> multiplied by 2 because of perimeter).28 = 6w - 12 + 2w (distribute)28 = 8w - 12 (combine like terms)40 = 8w (add 12 to both sides)5 = w <-- widthFind the length:
L = 3w - 6L = 3(5) - 6L = 15 -6L = 9 inAnswer:
The length is 9.

Help me order the side from shortest to longest
Answer:
Step-by-step explanation:
AB BC AC
(I’m not sure, If Im wrong let me knoww ❤️❤️)
Answer:
AC BA BC shortest to longest.
Step-by-step explanation:
All triangles have 180o in their interior angles. So A + B + C = 180
5x - 4 + 2x + 3 + 3x - 9 = 180 Combine the like terms on the left.
10x - 10 = 180 Add 10 to both sides
10x - 10 + 10 = 180 + 10
10x = 190
x = 190/10
x = 19
So <A = 5x - 4 = 91
<B = 2x + 3 = 41
<C = 3x - 9 = 48
Total 180
So the largest Line is opposite 91 and it is BC
The Middle sides line is opposite 48 and it is BA
The smallest line is opposite 41 and it is AC
AC BA BC shortest to longest.
Emily Elizabeth has $1.50 in dimes and nickels. She has 22 coins in all. How many nickels does she have?
Answer:
[tex]14[/tex]
Step-by-step explanation:
We can set up the following system of equations:
[tex]\begin{cases}10d+5n=150\\d+n=22\\\end{cases}[/tex], where [tex]d[/tex] is the number of dimes she has and [tex]n[/tex] is the number of nickels she has.
Multiplying the second equation by -5 and adding both equations lets us isolate and solve for [tex]d[/tex]:
[tex]10d+5n+(-5(d+n))=150+(-5(22)),\\5d=40,\\d=8[/tex]
Plugging [tex]d=8[/tex] into any of the two equations will let us solve for [tex]n[/tex]:
[tex]8+n=22,\\n=\fbox{$14$}[/tex].
Therefore, she has 14 nickels.
