Known fact:

$100 dollars for 8 hours of work --> $100 / 8hrs = $12.50 dollars/hrs

Two hours of work = $12.50 dollars/hr * 2hrs = $25 dollars

Six hours of work = $12.50 dollars/hr * 6hrs = $75

Ten hours of work = $12.50 dollars/hr * 10hrs = $125

fourteen hours of work = $12.50 dollars/hr * 14hrs = $175

Thus the answer is the bottom left choice.

A snack food manufacturer uses 2,000 kg of peanuts to make two different snack products. Product A contains 30% peanuts by mass

GalinKa [24]

Answer: 1250 kg.

Step-by-step explanation:

Let x = mass of product A.

y=mass of product B

Then , According to the given statement , we have

$0.3x+0.7y=2000-------------(1)\\\\x=3y-----------(2)$

Put value of x from (2) in (1) ,we get

$0.3(3y)+0.7y=2000$

$0.9y+0.7y=2000$

$1.6y=2000$

$y=\dfrac{2000}{1.6}=\dfrac{20000}{16}=1250$

Put value of y in (2) ,we get x= 3(1250)=3750 =mass of product A

Therefore, the mass of product B =1250 kg.

What is the answer?8x = 36 + 18y9x = 28 + 4y

Alexxx [7]

8x = 36 + 18y ⇒ -2(8x = 36 + 18y) ⇒ -16x = -72 - 36y

9x = 28 + 4y ⇒ 9(9x = 28 + 4y) ⇒ <u> 81x</u> = <u>252 + 36y</u>

65x = 180

$\frac{65x}{65} = \frac{180}{65}$

x = $\frac{36}{13}$

9x = 28 + 4y

9 $(\frac{36}{13})$ = 28 + 4y

9(36) = 13(28 + 4y)

324 = 364 + 52y

-40 = 52y

$\frac{-40}{52} = \frac{52y}{52}$

$\frac{-10}{13} = y$

Answer: x = $\frac{36}{13}$ , y = $\frac{-10}{13}$
