Answer:
The sum of 5x+3 is 5x+3. The opposite of 12 is -12.
Answer:
935 = 6a + 3.5c (this is the amount that has been raised)
210 = a + c (this is this amount of the dinners being sold)
Step-by-step explanation:
so a = 210 - c
935 = (6 * (210 - c)) + 3.5c
6 * 210 is 1260, so:
935 = 1260 - 6c + 3.5c
2.5c = 1260 - 935
2.5c = 325
so c = 130
a = 210 - 130 = 80
We know that 80 adult dinners were sold.
We also know 130 child dinners were sold as well.

Step-by-step explanation:
Focus on #7. Let's combine the first two matrices inside round parentheses.
We get
-2 - 1
4 + 3
and so the original problems becomes
-3 4
3( [ ] + [ ] )
7 2
Combining the two matrices, we get the following:
1 3
3([ ]) = [ ]
9 9
