Answer:
y = 40 is the answer
Step-by-step explanation:
Let the number be y
10 more than 2 times a number = 10 + 2×y
equal to 2 times the number plus 50. = 2 × y + 50
10 + 2y = 2y + 50
combine the like terms
2y - 2y =50 - 10
0 = 40
the number supposes be 40 but the number is represented by 0
i think some thing is missing in your question
y supposes be 40 not 0 = 40
Hope this helps!
Answer:
Step-by-step explanation:
<em>Hey there!</em>

Well to find the solution the the given system,
3y - 2x = -9
y = -2x + 5
So to find x lets plug in -2x + 5 for y in 3y - 2x = -9.
3(-2x + 5) - 2x = -9
Distribute
-6x + 15 - 2x = -9
-8x + 15 = -9
-15 to both sides
-8x = -24
Divide -8 to both sides
<u>x = 3</u>
<u />
Now that we have x which is 3, we can plug in 3 for x in y = -2x + 5.
y = -2(3) + 5
y = -6 + 5
<u>y = -1</u>
<u><em /></u>
So the solution is (3,-1).

Answer:
To figure out the change, we subtract the original temperature by the following after temperature.
18°F - original
-9°F - subsequent time after original
So we set up the equation;
18°F - (-9°F)
(Two negatives combine to form a positive)
18°F + 9°F
= <u>27°F</u> was the change in temperature.
Answer:
3 trips
Step-by-step explanation:
We would divide the amount of riders the roller coaster could take in a single trip by the total number of riders to determine how many trips it can make.
max amount of riders/total riders
72/24 = 3
Hence, the rollercoaster made 3 trips.
