Answer:
D
Step-by-step explanation:
2x + 3y = 18
3x - 3y = 12
the 3y and -3y cancel and you add the other like terms
5x = 30
x = 6
plug x back into any of the equations
2(6) + 3y = 18
12 + 3y = 18
3y = 6
y = 2
answer is (6,2)
The answer to this is -700
Answer:
Step-by-step explanation:
If any thing is in the brackets you need to do it first
so if you do 3 + x × 4 it will give yo 4x + 3 or 3 +4x
.011 = 1.1* 10^-2 in scientific notation
1.1*10^-2 * 7.5 * 10^18 = (1.1*7.5) * 10 ^ (-2+18)
8.25*10^16
The sand weighs 8.25 * 16^16 grams.
