What does "minimize the computer" mean?
You can solve this with proportion
1) For 2h
9/2 mile : 3/4h = x mile : 2h => (3/4)x=(9/2)*2 => (3/4)x=9 => x=9*(4/3)= 12miles
For 3h => (3/4)x=(9/2)*3 When we divide equation with 3 we get
x/4=9/2 => x=(9/2)*4=18 miles
2) 2 combine : 320 acres = 7 combines : x acres +: 2x= 320*7 =>
x= (320*7)/2 = 160 * 7 = 1120 acres
Good luck!!!
Answer:
$ 68
Step-by-step explanation:
Let original value of a single share to be $ x
For 17 shares, total value of shares will be $17x
After a decrease of $4 per share, new value of a share will be $ x-4
For 17 shares, total value of shares after decrease will be $ 17(x-4) = 17x-68
Total change in the value of her stock will be ; value of shares before decrease-value of shares after decrease
= 17x-(17x-68)
=17x-17x+68
=68
