Answer:
1 = A
2 = D
3 = B
4 = C
Step-by-step explanation:
2x+8b
First since 1 and 8b are on the same side mutiply them:
1bx8=8b
So our new equation is 2x+8b
If you are looking for the expression, that would be (x+4)/3
1/2k-3=2-3/4k
1/2k+3/4k=2+3
1.25k=5
1.25k/1.25=5/1.25
k=4
2800=400.21x
x = 6.996327
