Answer:
Step-by-step explanation:
b/c these are similar triangle we can say this ratio of the two triangles is true
15/x = 31/(44+x)
now just use algebra to solve for x
15*(44+x) = 31x
660+15x = 31x
660=16x
41.25 =x
41.3 looks good
No. Because no can be -1, either the solution is positive or the person wasn't born.
Answer:
4.000
Step-by-step explanation:
Answer:
400mph and 465 mph
Step-by-step explanation:
let the speed of first plane be x
speed of 2nd plane = x+65
dist travelled by first plane in 2 hrs = 2x
dist travelled by 2nd plane = 2(x+65)= 2x+130
when they meet, the sum of dist travelled by them is 1730
4x + 130 = 1730
4x = 1600
x = 400moh
x+65 = 465 mph
