The ordered pair is only a solution to the first equation, so it is not a solution to the system.

2 x 10 = 20 5 x 5 = 25 20 - 25 = -5 True!

10 + 2 x 5 = 11? False! 10 + 2 x 5 = 20

So, A and C are the correct answers!

What is the measure of segment PG?

agasfer [191]

The measure of the segment PG is mathematically given as

P G=17units. Option D

<h3>What is the measure of the segment PG?</h3>

Generally, the equation for is mathematically given as

$In $\triangle G H T$ \& $\triangle G J T$$

$\begin{aligned}&\angle G J T=\angle G H T \quad\left(\text { each } 90^{\circ}\right) \\\\&\angle G T J=\angle H T G\end{aligned}$

$G T=$ G $T$ (common)$

Hence $\triangle G H T=\triangle G J T$ (By AAS criteria)$

$G H=G J$ By cpct$

It is given that

$\mathrm{GH}=x+3$$$

$\ln =2 x-1$

Hence $G H=x+3=2 x-1$$$

$\text { as given } \begin{aligned}P G &=4 x+1 \\&=4 \times 4+1 \\&=17 \\\text { } & P G=17 \text { units }\end{aligned}$

In conclusion, The measure of the segment PG is given as

P G=17

Lexus skateboards from his house to school 4 miles away. It takes him 20 minutes.

RoseWind [281]

Answer:

$\displaystyle m = \frac{1}{5}\cdot t$

Step-by-step explanation:

<u>Proportional Model</u>

The number of miles m that Lexus can skateboard in t minutes can be modeled by:

m = kt

It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.

Substituting:

4 = k.20

Dividing by 20

$k=\frac{4}{20}$

Simplifying:

$k=\frac{1}{5}$

This produces the model

$\displaystyle m = \frac{1}{5}\cdot t$
