1) the odometer on your car reads
20,186.7 after going 62.3 miles. write and solve an equation to determoine how many miles were on the odometere before going 62.3 miles.
i wrote this; 0-62.3 = 20,186.7
2) michael bought a $25.00 gift for a friend. After he bought the gift, michael had $176.89. Write and solve an equation to calculate how much money Michael had before he bought the gift.
i wrote; g - 25.00 = 176.89
g - 201.89
3) This spring it rained a total of 11.5 inches. This was 3 inches less than last spring. write and solve an equation to find the amount of rain last season.
i wrote: r -3 - 11.5
r: - 14.5
are these correct?
You're right.
However your first equation is confusing. Please use a different letter than O which can be confused with 0.
miles on odometer before = miles on odometer after - miles traveled in between
20186.7 - 62.3 = 20124.4 miles
number 2 is supposed to be positive not negative.
r-3=11.5
r=14.5
thanks for the others though
Let's go through each problem and see if the equations you wrote are correct.
1) To determine how many miles were on the odometer before going 62.3 miles, you can subtract the 62.3 miles from the final odometer reading. The equation should be:
x - 62.3 = 20,186.7
Solving this equation will give you the initial odometer reading, denoted by "x". Let's solve it:
x = 20,186.7 + 62.3
x = 20,249
So, the initial odometer reading was 20,249 miles.
2) To calculate how much money Michael had before buying the gift, you need to add the cost of the gift to the remaining amount he had. The equation should be:
g + 25.00 = 176.89
Solving this equation will give you the initial amount Michael had, denoted by "g". Let's solve it:
g = 176.89 - 25.00
g = 151.89
So, Michael had $151.89 before buying the gift.
3) To find the amount of rain last season, you need to add the 3 inches to the total amount of rain this spring. The equation should be:
r + 3 = 11.5
Solving this equation will give you the amount of rain last season, denoted by "r". Let's solve it:
r = 11.5 - 3
r = 8.5
So, last season had a total of 8.5 inches of rain.
In conclusion, the correct equations are:
1) x - 62.3 = 20,186.7
2) g + 25.00 = 176.89
3) r + 3 = 11.5
And the solutions are:
1) x = 20,249 miles
2) g = $151.89
3) r = 8.5 inches
