Answer:
.
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.
You can multiply something by the 2,3,5,or 8 so you get to 104.
Answer:
x = 6
Step-by-step explanation:
Combine like terms here (anything with the same variable)
5x - 9x = -4x
6-2x = -4x+6
Add the lowest term in both sides
-2x + 4x = 2x
2x - 6 = 6
Add 6 to make 2x alone in order to get x
2x = 12
Divide both of the sides by 2 because that is how you get x all by itself
x = 6
