Roberto got $30 for his birthday. He decides to save that
shutvik [7]

After 10 weeks, the boys will have same amount in savings.

Step-by-step explanation:

Given,

Roberto already have $30.

Amount saved each week = $5

Let,

x be the number of weeks.

R(x) = 30+5x

Amount saved by Jack each week = $8

J(x) = 8x

For same amount, the functions will be equal.

R(x) = J(x)

30+5x=8x\\30=8x-5x\\30=3x\\3x=30

Dividing both sides by 3

\frac{3x}{3}=\frac{30}{3}\\x=10

After 10 weeks, the boys will have same amount in savings.

In a parallelogram, opposite angles are congruent, adjacent angles are supplementary, and opposite sides are congruent.

  A.) JH = FG = 1 in

  B.) GH = FJ = 3/4 in

  C.) m∠F = m∠H = 62°

  D.) m∠J = m∠G = 180° -62° = 118°

Two trains leave the station at the same, one heading west and the other east. The westbound train travels at 55 miles per hour.
Mars2501 [29]

The time that taken for the two trains is 1.2 hours.

The computation of the time taken for the two trains is shown below:

Given that

The westbound train travels 55 miles per hour.

And, the eastbound train travels 75 miles per hour.

So, the total speed is

= 55 miles per hour + 75 miles per hour

= 130 miles per hour

The distance is 156 miles

So, the time taken is

= \frac{distance}{speed}\\\\= \frac{156\ miles}{130\  miles\ per\ hour}\\\\

= 1.2 hours

Therefore we can conclude that the time that taken for the two trains is 1.2 hours.
