Answer:
1/2 (x+5) = 36 should be the equation that is used to determine how many rocks George started with.
Step-by-step explanation:
Let 'x' be the number of rocks George had.
As George gave, after getting 5 new rocks, half of his rock collection to Susan which is = 36 rocks
It means after getting 5 new rocks George's total rocks = 72
Given that he gave half collection to Susan = 36
Thus, before inducting 5 new rocks Georg's total rocks were = 67
Thus,
1/2 (x+5) = 36 should be the correct equation.
solving
1/2 (x+5) = 36
Multiplying both sides by 2
1/2 (x+5) × 2 = 36 × 2
x+5 = 72
x = 72 - 5
x = 67
Thus, before getting 5 new rocks, the number of rocks George had = 67
Therefore,
1/2 (x+5) = 36 should be the equation that is used to determine how many rocks George started with.
Y= 4/1 x -9 :) djsjsjdndndndj
To get the amount of miles that they drove for each gallon of gas, you have to divide 548.8 by 24.5 which equals 22.4. You can check this by multiplying the amount of miles per gallon times the amount of gallons and 24.5 * 22.4 = 548.8. So Tomasso's family drove 22.4 miles for each gallon of gas.
Answer:
4:9
Step-by-step explanation:
Not travelling: travelling
12 : 27
4 : 9
12 and 27 have 3 as a common factor
Therefore the ratio can be simplified to:
12/3 : 27/3
4 : 9
