Rise over run, so if the line had a slope of 3/5 you would go up 3 and over 5 to plot your next point. I hope this helped <3
Cos(x°) = (√3)/2
cos⁻¹[(√3)/2] = x°, that means x° = 30°
Answer:
B
Step-by-step explanation:
180-150=30
angle 3 is a right angle so it equals 90
all triangles add up to 180
so 90 + 30 is 120
180-120=60
a line is 180 degrees
so the answer is 120 B
Answer:
120 + 3.5x≤ 190
Step-by-step explanation:
Add up all the costs
80+ 10+10+20 + 3.50x where x is the number of cupcakes
Combine like terms
120 + 3.5x
This must be less than or equal to 190
120 + 3.5x≤ 190
W = 195
2/5D = 4/5W
2/5D = 4/5(195)
2/5D = 156
D = 390
