You jogged 3.7 total miles! 2.2 - 0/7 = 1.5 + 2.2 = 3.7! Hope I helped!
You could either find how far Chris can run in 60 minutes, or write an equation of ratios:
x 35 min
--------- = --------------
6 mi 50 min
Solving for x: 50x = 210; x = 4.2 miles (answer)
Answer:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations with the information given:
Build time (hours) = 4c + 6a = 120
Test time (hours) = 4c + 4 a = 100
Where c represents the number of child bikes and a represents adult bikes.
So, for 20 child bikes and 6 adult bikes:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100
Feel free to ask for more if needed or if you did not understand something.
Answer:
6

I counted
Answer:
B.
Step-by-step explanation:
Parentheses mean multiplication in this case. So it would be 2 x -3 OR -3 + -3. When multiplying a negative and a positive the answer will ALWAYS be negative. So you would move to the left on a number line.
