For this case we have the following equations:
2x - 3y = 1
2x + 3y = 2
When adding both equations we observe that:
Sentence 1: we have an equation of a variable, which in this case will be x. We can clear the value of x.
Sentence 2: Knowing the value of x, we can substitute in any equation and find the value of y.
Sentence 3: The value of x and y represents the point of intersection of both lines (x, y).
Answer:
8.5*
Step-by-step explanation:
825 million is
825,000,000
so you need to do 8.25 and then 10 to the power of 8
so the answer is 8.5*
Answer:
The first groups travels 7 miles total, and the second group travels 7 miles in total also
Step-by-step explanation:
They are completely equal
2(x + 3) = x - 4
distribute
2x + 6 = x - 4
either subtract 6 from both sides or add 4. i will be subtracting 6.
2x = x - 10
subtract x from both sides
x = -10
Answer:
the answer is 397.32
Step-by-step explanation:
333.75 ÷ 5.25 = 397.32
