Answer:
b or d
Step-by-step explanation:
#1.
[4x = -12y + 16 and x + 3y = 4]
One answer
#2.
Here, y = 4x + 3
y - 4x = 3
Multiply by 2,
2y - 8x = 6
Compare with second equation,
6 ≠ 3
In short, System of Equation does not have any solution. [ Option D ]
#3.
2y=6
3x-6y=18
Divide first equation by 2: y=3
Substitute y=3 into second equation: 3x-6(3)=18
Solve for x: 3x=36 x=12
Therefore there is only one solution: x=12 y=3
#4.
y - 7x = -14
7y - 49x = -2
Rewrite the first equation as "y =" so that it can be substituted into the second equation and solve for x.
y = 7x - 14
7(7x - 14) - 49x = -2
49x - 98 - 49x = -2
-98 = -2
Since the variables cancel and the equation is not true there is no solution.
The lines are parallel and will not intersect.
Answer:
25
___ x 40 = 10
100
Consider 25 out of hundred since its a percent and the key word "cent" means 100. The keyword "of" means multiplication.

The radius of the circle with arc length 40cm and central angle is 60 degree is 38.24 cm.
According to the given question.
Arc length of the circle = 40cm
Central angle, θ = 60 degrees
As, we know that the arc length of the circle, s with the radius r and central angle θ by using the formula
s = θ × (π/180)r
Therefore, the radius r of the circle with arc length 40cm and central angle 60 degrees is given by
40 = 60 × (3.14/180) r
⇒ 40/60 = 0.01744r
⇒ 0.66 = 0.01744r
⇒ r = 0.66/0.01744
⇒ r = 38.240
⇒ r = 38.24 cm
Hence, the radius of the circle with arc length 40cm and central angle is 60 degree is 38.24 cm.
