Answer:

The value of x is 1

Step-by-step explanation:

Let us solve the question

∵ Δ PQR ≈ Δ FGH

→ From similarity, then their corresponding sides have an equal ratio

∴ \frac{PQ}{FG} = \frac{QR}{GH} = \frac{PR}{FH}

∵ PQ = 3, QR = x + 3, PR = 2

∵ FG = 6, GH = 6x + 2, FH = 4

→ Substitute them in the ratios above

∴ \frac{3}{6} = \frac{x+3}{6x+2} = \frac{2}{4}

→ By using cross multiplication between the first two ratios

∵ 3 × (6x + 2) = 6 × (x + 3)

∴ 3(6x + 2) = 6(x + 3)

∴ 3(6x) + 3(2) = 6(x) + 6(3)

∴ 18x + 6 = 6x + 18

→ Subtract 6x from both sides

∵ 18x - 6x + 6 = 6x - 6x + 18

∴ 12x + 6 = 18

→ Subtract 6 from both sides

∵ 12x + 6 - 6 = 18 - 6

∴ 12x = 12

→ Divide both sides by 12

∴ x = 1

Segment HI has a length of 25.3 inches. It can be mapped to segment GO by a reflection over the x-axis followed by a reflection
OLEGan [10]
25.3, reflections do not change the length of something and if it can be mapped on to it they should be the same

Brian spends 3 5 of his wages on rent and 1 3 on food. If he makes £735 per week, how much money does he have left?
Margarita [4]

Answer :

Brian has $49 left.

Step by step explanation :

Step 1 : Find how much money Brian spends on rent and food.

First question we should be asking is what is 3/5 of 735?

Let's find that.

\frac{3}{5} * \frac{735}{1}

= \frac{(3)(735)}{(5)(1)}

= \frac{2205}{5}

= 441

We know Brian spends $441 on rent. Now we find how much he spends on food.

\frac{1}{3} * \frac{735}{1}

= \frac{(1)(735)}{(3)(1)}

= \frac{735}{3}

= 245

Brian spends $245 on food.

Step 2 : Add what he spends on rent and food together.

$441 + $245 = $686

Step 3 : To find out how much money Brian has left, we subtract $686 from $735.

$735 - $686 = $49

Conclusion : Brian has $49 left.

Hope this helps, please mark brainliest if possible. Have a nice day.
