Answer:

d. 15, 30, 135

Step-by-step explanation:

A triangle's interior angles on a flat surface add up to 180 degrees.

a. 90 * 3 = 270 != 180

b.(80 * 2) + 200 = 360 != 180

c.40 + 50 + 60 = 160 != 180

d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.

One Friday night, two large groups of people called Weston Taxi Service. The first group requested 2 sedans and 1 minivan, which
muminat

Answer:

Sedan: 4 passengers

Minivan: 6 passengers

Step-by-step explanation:

We can write the following system of equations:

\begin{cases}2s+1m=14 \\2s+2m=20\end{cases}, where s represents the number of people a sedan can seat and m represents the number of people a minivan can seat.

Subtracting the first equation from the second, we have:

2s+2m-(2s+1m)=20-14,\\\\m=6

Now plug in m=6 in any of the equations to solve for s:

2s+1(6)=14, \\2s=8, \\s=4

Verify that the solution pair (4, 6) works:

2(4)+1(6)=14\: \checkmark \\2(4)+2(6)=20 \: \checkmark

Therefore, a sedan can hold 4 passengers and a minivan can hold 6 passengers.
