equal amounts are invested at 2%, 7%, and 8% annual interest. if the three investments yield a total of $714 annual interest, find the total investment.

  $12600

Step-by-step explanation:

If x represents the total investment, then the total interest is ...

  (x/3)(0.02) +(x/3)(0.07) +(x/3)(0.08) = 714

  x(.17) = 2142 . . . . multiply by 3; collect terms

  x = 2142/0.17 = 12600

The total investment was $12,600.

step-by-step explanation:

f

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.
