Solve the equation.

1. 999 + k = 1,721 (1 point)
k = 2,720
k= 822
k = 722
k = 732
Solve the equation.
2. f + 523.89 = 812.57 (1 point)
f =1,336.36
f =1,336.46
f =299.68
f =288.68
Write and solve an equation for the situation.
3. Jamal and Keisha went running. Keisha ran 2.4 miles more than Jamal. If Keisha ran 8.5 miles, how many
miles did Jamal run?
(1 point)
2.4 + 8.5 = m; m=10.9 miles
2.4 + m = 8.5; m = 6.1 miles
2.4 + m = 8.5; m = 6.9 miles
2.4 + 8.5 = m; m = 11.9 miles
Write and solve an equation for the situation.
4. The sum of 7 and u is 14. (1 point)
7 + u = 14; u = 7
14 + 7 = u; u = 21
7 + u = 14; u = 8
7 + 14 = u; u = 21
5. Phil solved the equation x + 235.12 = 310.21, and found the solution to be 545.33. Is he correct? If not,
what was his mistake?
(1 point)
x = 545.33, so he is correct.
No, he is not correct, because x = 235.12. Phil used the other value on the same side of the equation as the
variable for the value of x.
No, he is not correct, because x = 75.09. Phil added 235.12 to 310.21 instead of subtracting.
No, he is not correct, because x = 74.09. Phil did not subtract 235.12 from both sides.

Thank you so much Jazmin

Jazmin is correct for Lesson 7: Equations with Addition. Do not listen to anyone else who said she is wrong because they are just trying to make you fail and they are lying. I got a 100% by using her answers. Please don't listen to them because Jazmin is right. Thank you Jazmin and have a great day everyone!

THANKS JAZMIN 100% ;))))))))

Jazmin number 5 is right
