Answer:

C) 160

Step-by-step explanation:

Set up a proportion:

\frac{9}{15} = \frac{x}{400}

Cross multiply and solve for x:

15x = 3600

x = 240

This means in 400 marbles, 240 are purple.

To find how many are not purple, subtract 240 from 400:

400 - 240

= 160 marbles

So, 160 marbles are not purple

Ella has $115. She wants to purchase a cell phone for $53 and spend the rest on music. Each music download cost $9. Write and so
Mumz [18]

Answer: 6.89


Step-by-step explanation:

9x+53>= 115

Subtract 53 from both sides

9x+(53-53) >115-53

9x>62

Divide both sides by 9.

9x÷9>62÷9 = 6.889

Shawna, Dexter, and Tilana are solving the equation Negative 2. 5 (5 minus n) 2 = 15. Shawna says, "I can begin by dividing each
aleksandrvk [35]

Shawana, Dexter, and Tilana are correct.

<h2>Given that</h2>

Equation: \rm  -2.5(5 - n) + 2 = 15&#10;&#10;&#10;

<h3>We have to determine</h3>

Which students are correct?

<h3>According to the question</h3><h3>Equation: \rm  -2.5(5 - n) + 2 = 15&#10;&#10;&#10;</h3>

The correct way to solve the equation is;

SHAWNA

Statement: Dividing each side of the equation by –2.5,

\rm  \dfrac{-2.5(5 - n) + 2 }{-2.5}= \dfrac{15}{-2.5}\\&#10;\\&#10;(5-n) - \dfrac{2}{2.5} =  \dfrac{15}{-2.5}\\\\&#10;\\&#10;

Here, Shawna is correct.

DEXTER

Statement: Distributing -2.5 to get -12.5 + 2.5 n + 2 = 15.

\rm -2.5(5-n) +2=15\\&#10;\\&#10;-2.5(5) - 2.5 (-n) +2= 15\\&#10;\\&#10;-12.5 +2.5n +2=15

Hence, Dexter is correct.

" Tirana says, "I can begin by multiplying each side of the equation by Negative Start fraction 1 over 2. 5 End fraction to get 5 minus n minus 0. 8 = negative 6. "

\rm \dfrac{-1}{2.5} (-2.5 (5-n)+2)= \dfrac{-1}{2.5}\times 15\\&#10;\\&#10;(5-n) + \dfrac{-2}{2.5} = \dfrac{-15}{2.25}\\&#10;\\&#10;(5-n) -\dfrac{2}{2.5} = \dfrac{-15}{2.5}\\&#10;\\&#10;5-n-0.8=-6

Hence, Tilana is also correct.

Hence, Shawana, Dexter and Tilana are correct.
