Pls help it’s 6th grade math

.

Step-by-step explanation:     The first answer is c. 7+3w, because the puppy already weighs 7 ounces. Since the puppy didn't end up losing those pounds, then you would add instead of subtract. Since the puppy gains 3 ounces a week, you would multiply the 3 ounces by the number of weeks that pass by. So, if one week passes, the puppy gains three ounces. Add that to the original 7 ounces, then after one week, the puppy weighs 10 ounces.

The second answer would be a. 22 ounces, because if you use the previous formula (x=7+3w), then you would plug 5 in for w. This would give you 7+3(5). 3x5=15 and 15+7=22. therefore, x=22 ounces.

7)c, 8)a

Step-by-step explanation:

since it is originally 7 oz, and grows 3 ounces a week, it would be 7+3w.

Substitutions would be 7+3(5) = 7+15 = 22 oz
