One number exceeds the other by 9 and their sum is 81. Find the
numbers.

36, 45

Step-by-step explanation:

Using equations you get because one number is 9 more than the other and the sum is 81. Simplifying you get, . Divide both sides by 2 to get . Remember this is only x so to get the other number you have to add 9 to 36 to get 45 as the other number.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
