Archy [21]3 years ago
6 0

Answer:

<h3>x = 300/7</h3>

Step-by-step explanation:

x + 40/100 × x = 60

x + 40/100x = 60

x + 0.4x = 60

Combine like terms.

1.4x = 60

Divide both sides by 1.4.

x = 42.857143

x = 300/7

kow [346]

Answer:

  C.  7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

  distance = speed × time

  300t = 350(t -1)

  300t = 350t -350 . . . . eliminate parentheses

  350 = 50t . . . . . . . . . . add 350-300t

  7 = t . . . . . . divide by 50

The trip out took 7 hours.

Answer:

x = 24 , y = 19

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , then

2x - 8 = x + 16 ( subtract x from both sides )

x - 8 = 16 ( add 8 to both sides )

x = 24

and

2y = y + 19 ( subtract y from both sides )

y = 19
