Why are the solutions to the proportions 40/8 = x/10 and x/40 = 10/8 the same?

romanna [79]

Answer:

Both proportions are equivalent.

Step-by-step explanation:

We have been given two proportions $\frac{40}{8}=\frac{x}{10}$ and $\frac{x}{40}=\frac{10}{8}$ . We are asked to find why the solutions to our given proportions are equal.

We can solve proportions by cross multiplying them.

After cross multiplying our both proportions we will get same equation that is:

$40*10=8*x$

$400=8x$

$8*x=40*10$

$8x=400$

Since we get same equation after cross multiplying both proportions, therefore, the solutions to the given proportions would be same.

tiny-mole [99]

Answer:

$\dfrac{\sqrt{10}}{4}$

Step-by-step explanation:

$\sqrt{\dfrac{5}{8}} =$

$= \dfrac{\sqrt{5}}{\sqrt{8}}$

$= \dfrac{\sqrt{5}}{\sqrt{4 \times 2}}$

$= \dfrac{\sqrt{5}}{2 \sqrt{2}}$

$= \dfrac{\sqrt{5}\sqrt{2}}{2 \sqrt{2}\sqrt{2}}$

$= \dfrac{\sqrt{10}}{2 \times 2}$

$= \dfrac{\sqrt{10}}{4}$

A clothes shop has some special offers.

castortr0y [4]

Answer:

The cost of 5 jumpers will be £ 58.40 (one more can be taken for free), the cost of 4 T shirts will be £ 9.60, and the total cost of the purchase will be £ 68.

Step-by-step explanation:

Since a clothes shop has some special offers, for which T-shirts are buy one get one free and jumpers are 3 for 2, and the normal price of a T-shirt is £ 4.80 and the normal price of a jumper is £ 14.60, to determine how much does it cost to get 5 jumpers and 4 T-shirts using this offer as appropriate, the following calculation must be performed:

4 T shirts = 2 + 2

4.80 x 2 = 9.60

5 jumpers = 2 (+1) + 2

4 x 14.60 = 58.40

Therefore, the cost of 5 jumpers will be £ 58.40 (one more can be taken for free), the cost of 4 T shirts will be £ 9.60, and the total cost of the purchase will be £ 68.
