Answer:
Area = 120
Step-by-step explanation:
Area = 1/2 bh
Area = 1/2 (10)(24)
Area = 1/2 (240)
Area = 120
The area of the right triangle is 120
Leah ordered $80 worth of merchandise
Answer:
15 weeks
Step-by-step explanation:
Let the number of weeks = x.
At the end of x weeks,
Jeremy has 120 + 14x,
and Katie has 180 + 10x
We want to know when their amounts are equal.
120 + 14x = 180 + 10x
4x = 60
x = 15
Answer: 15 weeks
Answer:

simplify 8/10 into 2/5 then 2/5 of 30 is 24
Answer:
perpendicular
Step-by-step explanation:
start but putting each line into the standard line format
2x-y=-5
-y=-2x-5
y=2x+5
x+2y=-6
2y=-x-6
y=-(1/2)x-3
if lines are parallel the slopes would be the same. 2 is not equal to -1/2
if lines are perpendicular the slope of one would be the opposite inverse of the other.
negative inverse of 2 = - (1/2)
so the lines are perpendicular
