Solve for the value of x

Mathematics
1 answer:
viva [34]2 years ago
4 0

Answer:

x=9

Step-by-step explanation:

To solve for x, you can set up a proportion between the 2 triangles we see.

The small triangle can be written as \frac{16}{20}, and the large triangle can be written as \frac{16+12}{20+2x-3} = \frac{28}{2x+17}.

Set both proportions equal to each other.

\frac{16}{20}=\frac{28}{2x+17}

Cross multiply and solve for x.

16(2x+17)=(28)(20)

32x+272=560

32x=288

x=9

2. Delia and Beto left for school at the same time.
Tema [17]

<u>Answer:</u>

Beto will get to the school first.

<u>Step-by-step explanation:</u>

We are given that Delia lives 3/4 mile from school and walks at a pace of

16 minutes per mile.

So Delia takes \frac{3}{4} \times 16 = 12 minutes to reach school.

While Beto lives 3 1/2 miles from school  and bikes at a pace of 3 minutes per mile.

So Beto takes \frac{7}{2} \times 3 = 10.5 minutes to reach school.

Therefore, Beto will get to the school first.
