tatuchka [14]

Answer: The Martinex family spent $ 82 for train ride and play tickets.

Step-by-step explanation:

Round trip train cost = $ 8.00

For children it cost $ 4.00.

For adult, ticket for play costs= $ 14.00

For children , ticket for play costs= $ 6.00

Mr. And Mrs. Martinez will go with their children, Ricky, Ramona, and Thomas.

2 adults and 3 children ( only one of them is under 7.)

For train we consider only 1 as child rest as adult.

Train cost = 4 x($ 8.00)+ 1 x ($ 4.00)

= $ 32+4 = $36

For play , total cost = 2 x ( $ 14.00) + 3 x ($6)

= $(28+18)

= $ 46

Total spending ( combined) = $36+$ 46

= $82

So, the Martinex family spent $ 82 for train ride and play tickets.

We know that consecutive angles in a parallelogram are supplementary, as they are consecutive interior angles between parallel lines.

Then, if we add the measure of x° and the measure of 5x° we get 180°. Then, we can write this expression and solve for x:

$\begin{gathered} x+5x=180 \\ 6x=180 \\ x=\frac{180}{6} \\ x=30 \end{gathered}$

Then, the angle x has a measure of 30° and the angle 5x has a measure of 5*30=150°.

Answer: a. 30°, 150°, 30°, 150°
