They add to 180
x+y+z=180
smallest (lets say that's x) is 36
36+y+z=180
minus 36 both sides
y+z=144
each term is the common difference away from the next term
z=y+d
y+y+d=144
and also
36+d=y so
36+d+36+d+d=144
3d+72=144
minus 72 both sides
3d=72
divide both sides by 3
d=24
common difference is 24
36+24=60
60+24=84
36+60+84=180
correct
largest angle is 84 degrees
Answer:
1.5 hours
Step-by-step explanation:
The ratio is 8:1, 8 being presents, one being hours. Half of 8 is 4, and eight +4 is 12, so it needs to be an hour and a half.
Answer:
Part A: y=5x
Part B: B and D
Step-by-step explanation:
The ratio of the number of cases to the total cost is 1:5. So, an equation that can be modeled by this situation in slope-intercept form is y=5x.
The unit rate actually does equal the constant of proportionality, so this is not true.
The unit rate of the number of cases per dollar is 1/5, so this is true.
No, the graph starts on the origin, so this isn’t true.
Points (0,0) and (1,5) are on the graph, so this is true.
25 cases will not cost $120, they will cost $125.
