Answer:

no solution

Step-by-step explanation:

- 4(x + 2) = - 4x - 5 ← distribute parenthesis on left side by - 4

- 4x - 8 = - 4x - 5 ( add 8 to both sides )

- 4x = - 4x + 3 ( add 4x to both sides )

0 = 3 ← False statement

This indicates the equation has no solution

Mala has a collection of bangles. She has 20 gold bangles and 10 silver bangles. What is the percentage of bangles of each type?

Rainbow [258]

Answer:

Percentage of gold bangles is 66.6 and of silver bangles it is 33.3

Step-by-step explanation:

Given:

Number of gold bangles Mala has = $20$

Number of silver bangles she has = $10$

Total number of bangles = $20+10$ = $30$

We have to find the percentage of each type of bangles.

So,

Percentage of bangles = $\frac{No.\ of \ bangles\ each\ type}{Total\ no.\ of \ bangles} \times 100$

Percentage of gold bangles.

⇒ $\frac{20}{30} \times 100$

⇒ $\frac{20\times 100}{30}$

⇒ $\frac{2000}{30}$

⇒ $\frac{200}{3}$

⇒ $66.6\%$

Percentage of silver bangles.

⇒ $\frac{10}{30}\times 100$

⇒ $33.3\%$

Percentage of gold bangles, Mala has = 66.6 and of silver bangles it is = 33.3

Solve: 3 1/2 + 3/9. 1) 10 1/2. 2) 11 1/2. 3) 1 1/6. 4) 1 2/6

In order to add the fractions, we need to create complex fractions with a Least Common Denominator (LCD).

The LCD between 9 and 2 is 18

3 1/2 = 3(18/18) + 9/18 = 54/18 + 9/18 = 63/18
3/9 = 6/18

So now we can solve...

3 1/2 + 3/9 is the same as 63/18 + 6/18 = 69/18 = 3 5/6 which is none of the given answers.
