= 24-3×5
=24-15
=9

Answer:
5/8
Step-by-step explanation:
Explanation:
First you need to put the same base for both numbers, finding the minimum common multiple of 4 and 8, that's 8.
Turning 1/4 in a number with 8 as base: first, divide 8 : 4 = 2. Then multiply 1/4 x2 and it will be 2/8.
Then you're able to calculate it: keep the base and add the tops
2/8 + 3/8 = 5/8
All you have to do is divide 433.44 by the price of the hamburgers, so
433.44 ÷ 3.87 = 112
The answer is 112 (:
When we want to determine the relative position of two lines, the first thing we can do is to write them in the same form.
We can use the form y=mx+k, where m is the slope.
the given lines are lines in plane. The "skew" case cannot be considered.
i) if 2 lines have same slope, but different k, then they are parallel,
ii) if 2 lines have equal slope (m) and k, then they are coinciding
iii) if the multiplication of their slopes is -1, then they are perpendicular
iv) if the slopes are not equal, and their multiplication is not -1, then the lines are intersecting
2.
4x+2y=8
2y=-4x+8, divide by 2
y=-2x+4
the other line is y=2x+4
-2 and 2 are not the same so the lines are neither parallel, nor intersecting.
-2 * 2 is not equal to -1, so the lines are neither perpendicular.
The lines are intersecting.
