Tamara rewrote the expression 0.2(4+1.4y-2.1). Her steps are shown.
Step 1: 0.2(4+1.4y-2.1)
Step 2: 4.2+1.6y-1.9
Step 3: 4.2-1.9+1.6y
Step 4: 2.3+1.6y
Which statement identifies and explains the first mistake
Tamara made?

Amuffin recipe, which yields 12 muffins, calls for cup of milk for every 1 cups of flour. the same recipe calls for cup of coconut for every cup of chopped apple. to yield a batch of 30 muffins, how much flour will be needed in the mix?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

For g(x) = 5x - 3 and h(x) = [tex]\sqrt{x}[/tex], find (g · h)(4)
