Step-by-step explanation:
Similar triangles
![\frac{AD}{AB}=\frac{DE}{BC}\\\\\frac{x+2}{x}=\frac{3}{2}\\\\](https://tex.z-dn.net/?f=%5Cfrac%7BAD%7D%7BAB%7D%3D%5Cfrac%7BDE%7D%7BBC%7D%5C%5C%5C%5C%5Cfrac%7Bx%2B2%7D%7Bx%7D%3D%5Cfrac%7B3%7D%7B2%7D%5C%5C%5C%5C)
Cross multiply
2*(x+2) = 3*x
2x + 2*2 = 3x
2x + 4 = 3x
Subtract 2x from both sides
2x + 4 -2x = 3x - 2x
4 = x
x = 4
Answer:
Amount spent by Tony = $49
Amount spent by Molly = 2 * 14
[49] + [2*49 + 14 ] = $161 = amonut spent by both
Answer:
1263 seconds
Step-by-step explanation:
100 meters = 12.63 seconds
multiply both sides by 100 since
100*100= 10,000 meters
12.63*100= 1263 seconds
80%=8/10
8/10x15=12
So 12 out of 15 flights. If simplified, 12/15=4/5
Hope this helps.
75,000 I’m 100% sure
What you do it 300 divided by 4% times 10
