Answers
Answer:
x = 14
AB = 37
BC = 36
AC = 28
PQ = 28
QR = 28
PR = 45
Step-by-step explanation:
we can add together the sides of ΔABC and set it equal to the sum of the sides of ΔPQR
2x+9 + 2x+8 + 2x = 2x + 2x + 3x+3
combine 'like terms':
6x + 17 = 7x + 3
subtract 6x from each side to get:
17 = x + 3
subtract 3 from each side to get:
14 = x
CHECK:
Does 6(14) + 17 equal 7(14) + 3?
84+17 = 98+3
101 = 101 checks out correctly

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
Answers
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

If your slope is 1/3 how do you move horizontally?
Answers
What is 1/3 as a slope?
The answer is approximately 18.43º. A slope of 1 in 3 means the slope is 1/3. It also means a rise of 1 and a run of 3. On a graph, starting at the origin, go up 1 unit, then from there, go to the right 3 units.

anybody know which once it is??
Answers
Answer:
It is the 3rd choice
Step-by-step explanation:
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.

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)

Which is the graph of 2x – 4y > 6?
Answers
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.

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.

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?
Answers
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.
