D. all you do is just subtract 9-2. that obviously equals 7....
Answer:
5<em>a</em>
Step-by-step explanation:
We know that Judy picked up 5 times as many apples as Marcus. We also know that Marcus has <em>a</em> apples. In order to find out how many Judy has, we simply multiple how many apples Marcus has by 5. When we do that, we get
5 x <em>a </em>= 5<em>a</em>
Answer: C, -4
Step-by-step explanation:

We want to isolate "m" on one side of the equation and have a number on the other side. Let's start by subtracting both sides by 5m


Now, let's subtract both sides by 11


We now have the value of m.
The next thing I'm going to do is a bit tedious, but you typically want to have the variable on the left side of the equation in the field of math. It's a good habit to develop now.

Thus, the answer is choice 3, -18. Let me know if you need any clarifications, thanks!

Answer:
Sam is 12, sam's brother is 19, and sam's mom is 32.
Step-by-step explanation:
First the equation you need to use is S+7+S+3S-4=63(the variable s represents Sam), you combine the like terms which then equals 5S+3=63, then you use inverse operations. Subtract 3 on both sides, 5S=60, then you divide on both sides which equals S equals 12. Then you just plug in the number, S is Sam which means Sam's 12. Then 12+7 which is 19, Sam's brother. Then 3 times 12 minus 4 is 32. And if you check to make sure, 12+19+32 does equal 63.
