Ok,
The total is 63$:
= 63
It shows us one of the numbers for the equation, 13
+ 13 = 63
Two passes together plus the thirteen equals the total of 63$
the price of the pass is unknown, so we can use a variable to figure it out:
2x + 13 = 63
Now we solve
First subtract 13 from both sides:
2x + 13 - 13 = 63 - 13
Then divide both sides by 2:
2x ÷ 2 = 50 ÷ 2
Now we get our answer:
x = 25
Answer:
Step-by-step explanation:
(-8, -5)
To form a rectangle, all the lines must be perpendicular and parallel. If you draw out the points on a coordinate plane then you can find the answer pretty easily.
Also, this one is easy because all the lines are vertical or horizontal, and when that is the case then you can just see which number in the set hasn't appeared twice (1 appeared twice as an <em>x</em> value, 0 appeared twice as a <em>y </em>value, but -8 has only appeared once as an <em>x</em> and -5 has only appeared once as a <em>y </em>value)
Answer:
(4, -6), (-10, -6), (-3, 1), (-3, -13)
Step-by-step explanation:
If we add/subtract t to/from any x/y coordinate, we will form a line segment with length 7. Hence, (4, -6), (-10, -6), (-3, 1), (-3, -13).
You sometimes need to rewrite a factor because the lead number is not between 1 and 10 as it needs to be in scientific notation. For instance, if we had lead numbers of 2 and 5, as we do in the following problem.
2x10^3 * 5x10^9
Then we get the answer of 10x10^12. We need to adjust this by moving the decimal place and increasing the exponent by 1. The correct answer would be 1x10^13 instead.
