Answer = $210
3/15.75 = 40/x
3x = 15.75 (40)
3x =630
x=210
200. Hope this helps you.
Answer:
A. 19.5
Step-by-step explanation:
Diagonals of a rhombus intersect at right angles. Therefore the angle opposite to AD = 90°.
Thus:
90° + x + 3x + 12 = 180° (sum of ∆)
Add like terms
102 + 4x = 180
Subtract 102 from each side
4x = 180 - 102
4x = 78
Subdue both sides by 4
x = 19.5
m here means measure
m<KLN means measure of angle KLN
Distance = rate x time
425 miles = (80mph + 90mph) x Time (t)
425 = 170t
t = 2.5 hours
You are trying to solve for time (t)
Therefore, 10am + 2.5 hours = 12:30pm
