a-5, b-4, c-1, d-3, e-2
Step-by-step explanation:
1) 3x+4 = 7x-8
-4x = -12
x = -3 (c)
2) 2x = 7x-5
-5x = 5
x = 1 (e)
3) 5x-8 = 5x+12
0x = 20
no solution (d)
4) 8x+4 = -2x-16
10x = -20
x = -2 (b)
5) -3x+5 = -3x+5
all real numbers (a)
x=30
step-by-step explanation:
0.6, 3/5, and 6% are the 3 same portion.
but, when they're all changed to a decimal they would equal to 0.6.
hope this , good luck!
