Answer:
45, 46 & 47
Step-by-step explanation:
n + n+1 + n+2= 138
3n + 3 = 138
3n = 135
n = 45
Therefore the three integers are 45, 46 & 47
Plug everything in
5-10-8=-13
Answer:

Step-by-step explanation:
Answer:
6.5
Step-by-step explanation:
9x=58.50
This equation is telling us that she bought 9 tickets at x cost each and the total was 58.50
Simplify the equation to solve for x. Divide by 9 on both sides.
⁹ˣ/₉ = ⁵⁸·⁵⁰/⁹
x=6.5
Parallel lines have the same slope. for example, the two lines y = 6x + 3 and
y = 6x - 5 are parallel because they have the same slope, 6x.
the slopes of perpendicular lines are opposite reciprocals, which means that you would flip the numbers of the fraction and make it negative. for example, the opposite reciprocal of -3x is 1/3x.
also, parallel lines never intersect, whereas perpendicular lines intersect at a 90 degree angle.
therefore, it isnt possible for two lines to be both parallel and perpendicular.
