3. For questions 3 and 4, write an equation and solve.
y decreased by 23 is 52.9
(1 point)
52.9 – 23 = y; y = 29.9
y – 52.9 = 23; y = 75.9
y – 23 = 52.9; y = 75.9
52.9 – y = 23; y = 29.9
4. Mrs. Gonzalez baked cookies for her class. After 12 students each ate a cookie, there were 6
left. How many cookies did Mrs. Gonzalez bake?
(1 point)
c – 12 = 6; c = 18
c – 6 = 12; c = 6
c + 12 = 16; c = 6
12 – c = 6; c = 6
5. Samuel solved the equation h – 234 = 1,192 and found the solution to be h = 958. Is he
correct? If not, why not?
(1 point)
Yes, he is correct, because h = 958.
No, he is not correct, because he did not add 234 and 1,192 to find the value of h, which is 1,426.
No, he is not correct, because he did not multiply 234 and 1,192.
No, he is not correct, because he did not subtract 234 from 1,192 correctly.
