Answer:
a. C = 7x
b. $1820
Step-by-step explanation:
Let the number of students the bus carries be x.
a. It costs $7 for every student that they bus.
Therefore, the cost of the school hiring the bus is:
C = 7 * x
C = 7x
b. To bus 260 students, then, the cost will be:
C = 7 * 260
C = $1820
The answer is D because the opposite sides are equal to each other, so you have 2 of each measurement. Also, midsegments divide each side of the bigger triangle in half. So 2 (1/2AC + 1/2AB)= the perimeter of the quadrilateral but the 2 in front will cancel out both halves, so we are left with AC+AB (OPTION D)
Answer:
He needs 3.75 lbs of sugar and 1.25 lbs of water.
Step-by-step explanation:
Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.
Note
5 lbs - 100%
x lbs - 75%
Write a proportion:

Cross multiply:

So, he needs 3.75 lbs of sugar and 5 - 3.75 = 1.25 lbs of water.

Answer:
3 - 3i
Step-by-step explanation:
I think you meant:
6
------------
1 + i
To simplify this, that is, to "rationalize the denominator," multiply both numerator and denominator by the conjugate of 1 + i, which is 1 - I:
6(1 - i)
----------- = 3(1 - i)= 3 - 3i
1 -(-1)
