Answer:
A=40, B=60, C=80
Step-by-step explanation:
180/7 to find what "1" would be in the ratio then multiply 20*2, 20*3, 20*4.
The two planes are flying in opposite directions.One plane travels at 560miles per hour and the other travels at a speed of 500 miles per hour. As time proceeds, they would travel further from each other and that can be described by the equation that follows:
560(t)+500(t) =2000, since we are given a 2000 distance limit. Then we are to find the time when they are at this distance. Solve for t, which is equal to 0.53 hours or 32 minutes.
Answer:
k = -7
Step-by-step explanation:
Step 1: Write equation
-k/5 = 7/5
Step 2: Solve for <em>k</em>
- Cross multiply: -5k = 35
- Divide both sides by -5: k = -7
Step 3: Check
<em>Plug in k to verify it's a solution.</em>
-(-7)/5 = 7/5
7/5 = 7/5
42/6 but if you want to simplify, it's 7
