1/2 - 3/8 = 4/8 - 3/8 = 1/8
you have to find a common denominator before you can subtract. in this case it is 8
1. A = 2ab + 2ac = 2bc
2. A = 2b(a +c) + 2ac
3. 2b(a + c) = A - 2ac
4. b = (A - 2ac) / 2(a + c)
Answer:
One clay block = x = $2.50 from before.
One mold = y = $4.00
Step-by-step explanation:
Multiply the second one by -2 to get -12x-2y=-38.00
Add these equations to eliminate y:
-12x-2y=-38.00
3x+2y=15.50
Result: -9x+0y=-22.50
9x=22.50
x=$2.50
Hope this helps love. <3 xx
