Mean number simply means average.
Answer: here you go
Step-by-step explanation:
A) 2x + 4y = 14
B) 4x + y = 20
If you multiply equation A by -2, then when the equations are added, the x will be eliminated.
The solutions are:
X = 4.714285714285714
Y = 1.1428571428571428
Answer:
x > -3
Step-by-step explanation:
–3x + 6 < 15
Subtract 6 from each side
–3x + 6-6 < 15-6
-3x < 9
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 9/-3
x > -3
Find the scale of the two known sides:
24/20 = 1.2
Figure B is 1.2 times figure A.
X = 60 x 1.2 = 72
Answer: x = 72
