Kim solves math equations at the rate of .75 problems per minute. Jill solves math equations at the rate of .5 problems per minute, and has already solved 2 equations. The equations that represent this situation are the following:
y = .75x
y = .5x + 2
where x represents the minutes, and y represents the number of equations solved. After how much time have they solved the same number of equations?
8 minutes
8 minutes
6 minutes
6 minutes
1.6 minutes
1.6 minutes
2 minutes
Answer:
8 minutes
Step-by-step explanation:
since y represents the number of equations solved, and since the question requires that you find the time when they both solved the same equations
y = y
0.75x = 0.5x + 2
0.75x - 0.5x = 2
0.25x = 2
x = 2/0.25
x = 8
Which is the graph of 2x – 4y > 6?
Answer:
The fourth graph on the far right
Step-by-step explanation:
The answer does not include the origin, as if you substitute x=0 and y=0 back into the original equation you get 0>6 which is false. Therefore, we can exclude the second answer and the third answer.
Solving the inequality for y, 2x-4y>6 -4y>-2x+6 y>-2x/-4-6/4 y>1/2x-3/2
At x=0, y should be greater than -3/2. The fourth answer shows y is greater than -3/2 at x=0. Therefore, the fourth graph is the solution.

Challenge A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all of the
coins, 18% are pennies and 34% are dimes. There are 4 more nickels than pennies. How much
money does the bag contain?
Answer:
The bag contains $5.19 in coins.
Step-by-step explanation:
18% of 50 = 9
9 of the coins are pennies
9 cent value
34% of 50 = 17
17 of the coins are dimes.
$1.7 value
4 more nickels than pennies: 9+4 = 13
0.65 cent value
9 + 17 +13 = 39
50 - 39 = 11
11 of the coins are Quarters
$2.75 value
Add all of the coin values together:
0.09 + 1.70 + 0.65 + 2.75 = $5.19
The bag contains $5.19 in coins.

Step-by-step explanation:
we see clearly that the side (leg) lengths changed from 3 units to 1 unit.
so, the scale factor is 1/3.
answer D is correct.
I assume the center of the dilation is the origin (0, 0).
so, C' becomes (-1, 0), A' becomes (-2, 0), B becomes (-2, 1).
it was then reflected across the y-axis (flipped over from the left side of the y-axis to the right side).
C'' becomes (1, 0), A'' (2, 0), B'' (2, 1).
and then it was translated (shifted) by (+1, -2), so that
C''' = D = (2, -2), A''' = F = (3, -2), B''' = E = (3, -1)

4) Which expression is equivalent to 3x + 5x? X + 8 8x + 2. 8x. 2x
Answer:
8x
Step-by-step explanation:
3x + 8x are like terms which means they have the exact same variable.
To add like terms we add the coefficients which are 3 and 5.
3 + 5 = 8
We have 8 x's. So 3x + 5x = 8x.
In order to add terms, the variable part has to be exactly the same.
It's like saying 3 balls + 5 balls = 8 balls.

How long would it take before the Hendersons would recover their costs if they chose to do it themselves over the professional service? a. 5 months b. 9 months c. 10 months d. 6 months.
To solve the problem we will calculate the cost in both cases.
Hendersons will be able to recover their costs if they chose to do it themselves in 2 months.
Given to us
Do-It-Yourself Option
$250 for the lawnmower$135 for edger Includes mowing and edging $69 for hedge trimmer lawn, trimming the bushes, and $25 for rake, raking the leaves.Professional Service
$75 for the first month$45 per month after the initial visitTotal cost if they do it themselves,Total cost if they do it themselves = $250 + $135 + $69 + $25
= $479
So, it will take $479 for them if they start doing it by themselves.
Total cost if they take Professional Service for a yearTotal cost if they take Professional Service = Initial fees + monthly fee
= $75 + (11 month x $45)
= $570
So, it will charge $570 if they take Professional Service for a year.
Difference between the CostDifference between if they do it themselves and if they take a professional service
= $570 -$479
= $91
So, if they try to do it themselves they will save $91, which is approximately two times the monthly fee of the professional service.
Hence, Hendersons will be able to recover their costs if they chose to do it themselves in 2 months.

The ratio of red candies to blue is 5:3 as you probably learned, the ratio ':' sign also means the fraction division sign. So we can also write this as 5/3. Lastly how we READ a ratio is; something TO something. In this case if we were to read 5:3 we would say " Five to Three" since there is no choice spelling out the numerals we can just say " 5 to 3". All of these ways are given in the 3rd answer choice.
