Answer:
2 hours
Step-by-step explanation:
If you convert 1/5 to tenths it's 2/10.
If you add 2/10 and 3/10 you get 5/10 which would be how much off the task you got done in one hour.
Therefore you times 5/10 by 2 and you get 10/10 so the task is done and it took 2 hours.

Answer: B, C , and E are the answers
Step-by-step explanation:
First solve the expressions by breaking it down.
2h + g Nothing can be done to this expression because it is already broken down.
4(2h + g) Apply the distributive property to break it down.
4(2h) + 4(g)
= 8h + 4g
4h + 4h + 3g + g Combine like terms to break this one down
(4h + 4h) + (3g + g)
= 8h + 4g
1/4(2h + g) Apply the distributive property to break it down.
= 1/2h + 1/4g
2(4h + 2g) Apply the distributive property to break it down.
= 8h + 4g
1/8(8h + 4g) Apply the distributive property to break it down.
1h + 1/2g

15. Evan is sewing trim on a pair of shorts. He needs four equal length pieces of trim to put two stripes down each side of the shorts. The teacher gives him a piece of black trim that is 185 cm long. He measures and cuts 4 equal lengths. He ends up with a small piece of leftover trim that is 13 cm long. How long is each piece of trim?
a) Write an equation to represent this situation.
Answer:
43
you take 13 from 185 then divide that by 4
Step-by-step explanation:
Answer:
the answer is each piece of trim is 43 cm long
185-13 = 172

Answer: i will give you the first couple answers and how i got it you do the rest yourself. You need to combine like terms so add or subtract only the same numbers with the same sign. if the sign has no number imagine an invisible 1 before it. so for example the first one would be (4A) all i did was add the A together to get that i will also give you the last answer for another example. the problem is 20-9z+4y+7-x. all you gotta do is add 7 to the 20 add -9+-x and leave the 4y alone since there is no other y the answer would be 27-10z+4y+

Ben and his friends are going to play putt-putt. At one location, they can pay $2.00 for rentals plus $7.50 per game. At another location, it would cost $8.00 for rentals plus $6.00 per game. How many games would they have to play in order for either location to cost the same amount?
What is the best way to set up and solve the word problem?
2+7.50x=8+6x
2 plus 7 point 5 0 x is equal to 8 plus 6 x
6x+2=7.50x+8
6 x plus 2 is equal to 7 point 5 0 x plus 8
7.50x−2=6x−8
7 point 5 0 x minus 2 is equal to 6 x minus 8
6x−2=7.50x−8
6 x minus 2 is equal to 7 point 5 0 x minus 8

At an amusement park you get five points for each bull’s eye you hit, but you loose 10 points for every miss. After 30 tries, Yolanda lost 90 points. How many bull’s eyes did she hit?
Answer:
21
Step-by-step explanation:
14 bull's eyes (or hits) and 16 misses.
The 14 hits earned her five points each, or a total of 70 points.
The 16 misses cost ten points each, or a total of 160 points lost.
14 + 16 = 30
70 - 160 = -90
SOLUTION:
points = 5H - 10M = -90 where H = hits and M = misses
tries = H + M = 30 therefore
H = 30 - M
and 5(30 - M) - 10M = -90
150 - 5M -10M + 90 = 0
240 -15M = 0
15M = 240
M =16
H = (30 - M) = 16

An employee at a gift shop earns $72.00 for working 9 hours. At this hourly rate, what should the employee earn for a 40-hour work week?
A.$8.00
B.$48.00
C.$121.00
D.$320.00
At this hourly rate, the employee earns a 40-hour workweek is D.$320.00
In the above case, an employee earns $72.00 for working 9 hours a day or 9 hours, now to know about hourly earing we should divide $72.00 by 9 hours so that we can get the earnings of the employee on an hourly basis.
Therefore, earnings an hour = 72.00/9 = 8, which means the employee is earning 8 dollars for every hour he works at the gift shop, now to know how much money he/ she will generate in 40 hours we will multiply 8 dollars with 40 working hours.
Therefore total earnings of the week = earning per hour * total working hours = 8*40 = $320.00 for every 40-hour week. hence, the total earnings for the week will be $320,
Calculations
earning per hour =72.00/ 9 = 8
total earning = 40*8 = 320
correct option will be D. $320

Mr. Paulsen challenges Olivia and Angelica to move figure ABCDE onto figure A"B"C"D"E" using a series of two different transformations. They give two different answers.
Answer the questions to investigate ways to transform ABCDE.
1. Olivia finds a combination of two different transformations that moves ABCDE onto A"B"C"D"E". What is one way she might have done this?
2. Angelica reflects ABCDE over the y-axis and translates it up 8 units. Does her transformed figure match A"B"C"D"E"? If not, describe how her transformed figure compares to A"B"C"D"E".
3. Michael says he can move ABCDE onto A"B"C"D"E" with one transformation by translating ABCDE diagonally so that it moves 8 units up and 10 units right. Is he correct? Explain why or why not.
Problem 1
One method Olivia could have used is to reflect over the x axis and then translate 10 units to the right.
Let's apply these set of steps to point C.
C = (-2,-4)
C' = (-2,4) after reflecting over the x axis; y coordinate flips in sign
C'' = (8,4) after shifting to the right 10 units; add 10 to the x coordinate
Point C(-2,-4) moves to C''(8,4) which is shown in the diagram. I'll let you check the other four points.
-----------
Another method Olivia could have used is to shift to the right 10 units first, then reflect over the x axis. In this case, the order doesn't matter. Though for some other combinations of transformations, order does matter.
============================================================
Problem 2
Reflecting over the y axis will have the point (x,y) turn into (-x,y). Only the x coordinate changes, and we flip the sign here. The y coordinate stays the same.
A point like C(-2,-4) becomes C'(2,-4) after the y axis reflection. Shifting up 8 units means we add 8 to the y coordinate to arrive at C''(2,4) but this does not match what the diagram shows. Therefore, Angelica's method is incorrect.
You should find other inconsistencies for the other four points as well.
============================================================
Problem 3
Michael's method isn't correct either. He does not apply an x axis reflection and instead relies entirely on translations to move ABCDE to A''B''C''D''E''
At a quick glance, it looks like Michael may be correct. But upon a much closer look, you'll see that things don't line up perfectly.
Instead of point C, we'll pick on point D this time.
D is located at (-6,-2). If we shift up 8 units, then we add 8 to the y coordinate to get to D'(-6,6). Then add 10 to the x coordinate to shift 10 units to the right. This leads us to D''(4,6).
However, the diagram shows D'' is actually at (4,2)
I'll let you check the other points. You should find that only points C and E go to the correct locations, but the other points do not. Again, this is because Michael did not apply an x axis reflection. His figure of A''B''C''D''E'' is upside down compared to what it should be.
============================================================
To summarize, the methods described in problem 1 are the correct way to get ABCDE to move to A''B''C''D''E''. If Olivia followed either of those two methods, then she is correct. Both Angelica and Michael have incorrect methods.
Order these numbers from least to greatest.
