Check your formula, and if its slope its y=mx+b. Good luck you have the right answer.
Answer:
John's commute = x + 0.5
Sheila's commute = 2x
Step-by-step explanation:
Given:
Total hour commute = 2
Mark's commute = x
John's commute = x + 0.5
Sheila's commute = 2x
Find:
Each commute
Computation:
Total hour commute = Mark's commute + John's commute + Sheila's commute
2 = x + x + 0.5 + 2x
4x = 1.5
x = 0.375 hour
John's commute = x + 0.5
John's commute = 0.375 + 0.5 = 0.875 hour
Sheila's commute = 2x
Sheila's commute = 2(0.375) = 0.75 hour
the answer of this is 19.5 pounds
Answer:
9x
Step-by-step explanation:
X is an unknown variable so just leave x as it is
Because the (2x) and the (7x) are being multiplied together they are almost seen as their own category of things
Think about having two bananas in a bowl. I just threw in seven more to get a total of nine bananas in the bowl.
It's the same thing when you have a variable right next to a number! add them together as if they are alike terms.
2+7=9 therefore your answer should be 9x
4) Let A = {7, 8, 9, 10, 11, 12), B = {9, 11, 13), C = {7, 8, 10, 12), D = {7, 12), and U = {7, 8, 9, 10, 11, 12, 13). 4) Вас A)
Elenna [48]
It is true as A consist {7,8,9,10,11,12} and B consists of{9,11,13} and C consist of {7,8,10,12} and D has{7,12} there are the set of numbers from 7 to 13 only so the answer is true that U={7,8,9,10,11,12,13}.
