Answer:
4
Step-by-step explanation:
12+8 = 20
20/5 = 4
7 / 2 1/3 = 7/1 / 7/3 = 7/1 * 3/7 = 21/7 = 3 ( enough flour for 3 batches of muffins)
1 1/2 * 3 = 4 1/2 cups of brown sugar needed
I only know 1 & 4 .. 2 & 3 seem hard to me ..
X >7
X< -7
-
Move the x's to the same side
2x + x = 8 +6
then simplify
3x = 14
make x stand on its own
(3x)/3 = 14/3
the 3's on the x side cancel
x = 14/3
