$\huge \bf༆ Answer ༄$

Let's solve ~

<h3>A. 5(x - 4) = 10 </h3>

$\sf5(x - 4) = 10$

$\sf(x - 4) = 10 \div 5$

$\sf \: x - 4 = 2$

$\sf x = 2 + 4$

$\sf x = 6$

<h3>B. 2x(4x + 3x) = 21 </h3>

$\sf2x(4x + 3x) = 21$

$\sf2x(7x) = 21$

$\sf14 {x}^{2} = 21$

$\sf {x}^{2} = 21 \div 14$

$\sf x {}^{2} = \dfrac{3}{2}$

$\sf x = \sqrt{ \dfrac{3}{2} }$

<h3>C. 3(4 - 2x) = 28</h3>

$\sf3(4 - 2x) = 28$

$\sf12 - 6x = 28$

$\sf - 6x = 28 - 12$

$\sf x = 16 \div - 6$

$\sf x = - \dfrac{8}{3}$

<h3>D. 10x(2 + 13) = 300</h3>

$\sf 10x(2 + 13) = 300$

$\sf10x(15) = 300$

$\sf10x = 300 \div 15$

$\sf x = 20 \div 10$

$\sf x = 2$

I hope it helps ~

a basketball player attempted 15 baskets in the game he makes 9 of the attempted baskets which ratio describes the number of bas

goldenfox [79]

Answer:

3:5

Step-by-step explanation:

We are given that

Basket player attempted basket=15

He makes number of attempted basket=9

We have to find the ratio which describes the number of baskets the player made to the number of baskets to play attempted.

$\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{9}{15}$

$\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{3}{5}$

Hence, the ration which describes the number of baskets the player made to the number of baskets to play attempted=3:5

8. A furniture shop sells sofas for $880. If the shop wanted to offer the lower price of $640, what rate of markdown would it ha

geniusboy [140]

Answer:

The rate of markdown it would have to offer is 27.3%.

Step-by-step explanation:

The original price of sofa was, OP = $880.

The new price of sofa is, NP = $640

The change in price is:

$Change=OP-NP\\=880-640\\=240$

The rate of markdown offered by the shopkeeper is:

$Rate\ of\ markdown=\frac{Change\ in\ Price}{Orignal\ Price}\times100 \\=\frac{240}{880}\times100\\ =0.27273\times100\\\approx27.3\%$

Thus, the rate of markdown offered by the shopkeeper is 27.3%.
