Answer:
Option C. x=7
Step-by-step explanation:
we know that
If PQ is parallel to BC
then
triangles APQ and ABC are similar
Remember that
If two figures are similar them the ratio of its corresponding sides is proportional
so

substitute the values

Solve for x

<span>He will get 42,888,000 in ten years
</span>
Divide 153 by 13 which is 51.
There is no need to round to the nearest tenths
The amount of money Emma receives in this scenario is £35.
<h3>What is Ratio?</h3>
This is defined as a comparison of numbers that indicates their sizes in relation to each other.
Helen and Emma = 2 : 5
2 = 5
x = x+21
We then cross multiply
5x = 2 ( x+21)
5x = 2x + 42
5x - 2x = 42
3x = 42
x = 42/3 = 14
Emma received x+21
= 14+21 = £35

7.5 = x +

equals
x = 6.
First, subtract

from both sides. / Your problem should look like: 7.5 -

= x.
Second, simplify 7.5 -

to 6. / Your problem should look like: 6 = x.
Third, switch sides. / Your problem should look like x = 6, which is your answer.
