Answer:
.003508 kg of copper
Step-by-step explanation:
1000 grams = 1 kg
3.508 g/1000 g = .003508 kg
I think it's equal to 1 because every expression with the exponent of zero is equal to 1, idk for sure though
It has 90 degrees so it's right
And none of the sides are equal so it's scalene
Step 1: multiple the second equation by 2 so that you get -1/4 for the coefficient of y, the same as in equation 1
equation 2 multiply by 2: 1/4 x - 1/4 y=38 ..........name this equation 3
subtract equation 1 from equation 3: (1/4 x -1/2 x)=38-10
-1/4 x = 28
x=-112
plug in x=-112 in any of the equation, you will get y=-264
so the answer is A
