Which equation has infinitely many solutions? a 12 + 4x = 6x + 10 - 2x
b 5x + 14 - 4x = 23 + x-9 c
c X + 9 -0.8x = 5.2x + 17-8
d 4x-2x = 20
Answer:
x > 6
Step-by-step explanation:
Thanks to the definition of mean, we can write this inequality:
(4.5 + 5.7 + 5.2 + 4.2 + 4.4 + x)/6 > 5
(24 + x)/6 > 5
24+ x > 30
x > 6
Answer:
MN = 55
Step-by-step explanation:
Since T is the circumcenter of ∆MNP, it follows that the perpendicular bisector of side MN divides MN into two equal parts.
Therefore:
MR = RN
MR = 10x -13
RN = 17x - 41
Thus:
10x - 13 = 17x - 41
Collect like terms
10x - 17x = 13 - 41
-7x = -28
Divide both sides by -7
x = 4
MR + RN = MN
(10x - 13) + (17x - 41) = MN
Plug in the value of x
(10(4) - 13) + (17(4) - 41) = MN
(40 - 13) + (68 - 41) = MN
27 + 27 = MN
54 = MN
Answer:
If a²+b²=c² then....
Step-by-step explanation:
....a(4)²+b(3)²=c(x)²
16+9=5² or 25
Answer:
31.7
Step-by-step explanation:
AB = 6 BC = 3 CD = 4 DE = = 5.831
EF = 3 FG = = 3.162 AG = = 6.708
Perimeter = 6 + 3 + 4 + 5.831 + 3 + 3.162 + 6.708 = 31.7
