Set up a proportion
42.50/5=x/8
5x=340
x=68
He would earn $68
So 5,10,15,20,25,30,35,40,45 so Aylson needs 1 more bead. Because 45 beads are already used!
Answer:
Algebra book weighs 24 oz
Grammar book weighs 15 oz
Step-by-step explanation:
algebra = x and grammar = y
x = 2y-6
5x = 8y
5(2y-6) = 8y
10y - 30 = 8y
2y - 30 = 0
2y = 30
y = 15
x = 2(15)-6
x = 30-6
x = 24
4 + 2h < -3
2h < -7
h < -3.5
x ∈ (-∞, -3.5)
So 15-7 is 8
Here are some things I did:
10-2 or 28-20
