Okay so the first thing you for for is to see if you can reduce your numbers and you can in this problem. You can reduce the 8 and 12 by 4, meaning that you can divide them by 4. So your problem would now be 2x7/3. Now to calculate your product you just times 2x7 and you’re answer is 14/3 :)
Answer:
Step-by-step explanation:
8. subtract 78 from both sides so you get r=-93
10. divide both sides by 8 so you get j=12
11. divide both sides by -13 so its z=3
12.divide both sides by 15 so its m=-12
13. divide both sides by 27 to get r=9
14. multiply both sides by 9 (9/1) to get y=-72
15. multiply both sides by 12 to get -j=-96 then divide it by - to get j=96
16. multiply it by 15/1 so its a by itself and then use cross multiplication to simplify it so 4/5 x 15/1 so 15 becomes 3 and 5 becomes 1 so its 4x3 which is 12 so a=12
17. g=6
18. q=4
Speed = Distance / time:
Speed = 825 miles / 17 hours
Speed = 48.529 miles per hour. (Round the answer as needed).
Gas mileage = miles traveled / gallons used
Gas mileage = 825 miles / 38 gallons = 21.71 miles per gallon (Round answer as needed).
Unit rate of gas = Total money spend / gallons bought:
Unit rate of gas = $125 / 38 gallons = $3.289 per gallon.
