Answer:

let's see what to do buddy...

Step-by-step explanation:

$\frac{zinc}{copper} = \frac{3}{17} \\ \\ \frac{zinc}{799} = \frac{3}{17}$

Multiply the sides of the equation by 799

$zinc = \frac{3}{17} \times 799 \\ \\ zinc = \frac{3}{17} \times 17 \times 47 \\ \\ zinc = 3 \times 47 = 141$

So A jar of the chemical contains 141 grams of zinc.

And we're done.

Thanks for watching buddy good luck.

1. Choose the correct simplification of the expression −5x2(4x − 6x2 − 3).

nlexa [21]

1) 30x4 − 20x3 + 15x2

This is the answer to 1. Don't forget to rearrange the terms in ascending order. That can trip people up.

2) x3 + 8x2 + 13

Don't forget to check the terms sign. The subtraction symbol switches them all.
