Answer:
2 to 6 is constant. 14 to 15 is constant. The height characterized by the line remains straight.
Step-by-step explanation:
Looking at the graph, we can identify the x axis which is time, and the y axis which is the height. Now, as the height increases or decreases, so does the line as it goes higher or lower. Now, when the question asks what constant means, it is asking where during the graph is the height the same. We can see that it is the same when the height does not change over time, which is from 2 to 6. The height remains the same, therefore there is no change and the height is constant.
Answer:
That is foiling. You are just breaking the equation by solving it.
Hope that helps and feel free to ask me more questions :)

Now I am not sure what length you're supposed to find for problem 9, but x = 3.3 i think.
10.)
(14+x)+(x+21) = 13
2x+35=13
2x = -22
x = -11
FE = -11 + 14 = 3 units
11.)
10 + 2x - 10 = 3x - 8
2x = 3x - 8
-x = -8
x = 8
10 + 2(8) -10 = 16 units

Answer:
1050 masks per person.
Step-by-step explanation:
1) Create an equation to find the total number of masks
2) Solve equation and divide total by 2 to get the number of masks that can be given to both Mark and Paula so that they have equal number.
1) Since Paula has 70% of the total masks, it can be represented as 0.7 * t where t is the variable representing the total number of masks. Mark on the other hand has the remaining number of masks out of 100% which is 30%. We can express that as 0.3. We multiply that by t because he has 30% of the masks. The final equation we have is 0.3t + 840 = 0.7t. 840 because Paula has 840 more masks than Mark.
2) Solve by subtracting 0.3t from both sides leaving you with 0.4t = 840. We divide both sides by 0.4 to get 2100. That is the total number of masks. If we divide that number by 2, we get 1050.
