The weight of copper is 8 1/10 in the gram.
I add 2x + 3x to get 13 1/2 to find what x is to multiply back into the ratio to find the weight of copper.
So the equation is 5x=13 1/2
Solving it we get x=27/10.
Now we multiply 27/10 * 3 to find the weight of copper. The answer is 81/10, simplifying into 8 1/10. This means that the weight of Zinc is 5 2/5, we get this by subtracting 13 1/2 to 8 1/10.
Hope this helps!
Answer:
See below ~
Step-by-step explanation:
<u>A.</u>
- m∠5 = m∠10 (alternate angles)
- m∠10 = 69°
<u>B.</u>
- ∠4 + ∠14 = 180° (∠14 is equal to ∠8 as they are corresponding, and ∠8 is supplementary to ∠4)
- ∠14 = 180° - 114°
- ∠14 = 66°
<u>C.</u>
- ∠5 = ∠12 (as ∠10 = ∠12 by alternate interior angles, and ∠10 = ∠5 as alternate angles)
- ∠12 = 86°

The answer is A!
Sadie is correct because 3(2x+3y) equals 6x+9y
Your answer is going to be -2.7, -0.6, -0.5
To figure out which numbers are greater than others, you just need to look at a number line. There are two sides to a number line, with 0 being in the middle. When looking to the negative (left) side, the further left you go, the smaller the numbers will be. However, when looking to the positive (right) side of the 0, the numbers gradually get bigger.
