Answer:
B it maybe wrong not 100% sure
Step-by-step explanation:
I don know
17/10-(2/5x2/2)
17/10-4/10
=13/10
Answer: x = 1.4
Step-by-step explanation:
Simplify:
6-5x+1 = 0
Subtract 1 from both sides:
6 -5x = -1
Subtract 6 from both sides:
-5x = -7
Divide both sides by -5:
x = 1.4
Answer: Yes
Step-by-step explanation:
x = 3
y = -7
10x + 20y ≥ -3
10 (3) + 20 (-7) ≥ -3
30 + (-140) ≥ -3
30 - 140 ≥ -3
-110 ≥ -3
(3, 7) is a solution
