Make two equation
First number: A
Second number: B
A + B = 40
A - B = 6
Now use elimination and subtract
2B = 34
B = 17
A + 17 = 40, A = 23

Solution: 17 and 23

In a certain chemical, the ratio of zinc to copper is 3 to 17. A jar of the chemical contains 799 grams of copper. How many gra

dezoksy [38]

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 <em><u>zinc</u></em>.

And we're done.

Thanks for watching buddy good luck.

Ruiz needs to buy a countertop for a kitchen. He calculated the area to be 16 square feet. The actual area is 15.4 square feet.

Marina86 [1]

First, subtract the two values:

16 - 15.4 = 0.6

Now divide this to the actual area:

0.6 / 15.4 = 0.038961039

Multiply by 100:

0.038961039 * 100 = 3.8961039

So the percent error is approximately 3.9%

Find the area of each triangle.

lord [1]

Hi there!

We can find the area of a triangle with the formula:
$area = 0.5 \times base \times height$

Filling in this formula gives us the following answers.

Triangle 1
$area = 0.5 \times 5 \times 8 = 20$

Triangle 2
$area = 0.5 \times 7 \times 9 = 31.5$

Triangle 3
$area = 0.5 \times 16 \times 12 = 96$
