answer;
x=0
Step-by-step explanation:
4 + 2 (x + 3x) = 4 - x(2-3) + 2x
let remove d brackets
4 + 2x + 6x = 4 - 2x + 3x + 2x
llet collect like terms
2x + 6x - 3x -2x + 2x = 4-4
5x = 0
x = 0
Answer:
Infinitely many.
Step-by-step explanation:
3x + 2y = 4
-6x - 4y = -8
Note that the second equation is obtained from the first by multiplying the first one by -2. Thus the graph of the 2 equations is the same line and there are infinitely many solutions.
Answer:
Step-by-step explanation:
<u>Factorize both numbers:</u>
- 900 = 2*2*3*3*5*5
- 270 = 2*3*3*3*5
<u>Common factors are:</u>
<u>So HCF is:</u>
- HCF(900, 270) = 2*3*3*5 = 90
Answer: 3.75
Step-by-step explanation: 15 divided by 4 equals 3.75
The arc length of the circle exists 846.65922 cm.

How to estimate the central angle in degree? </h3>
A unit circle by definition contains a radius of 1 unit.
We have to estimate the length of the arc subtended by an angle of 
radians.
arc length = radius 
angle
s = r
Where s be the arc length
r be the radius of the circle
be the angle measured in radians
arc length = 77cm
arc length = 77 7(3.14) / 2
arc length = 846.65922 cm
Therefore, the arc length of the circle exists 846.65922 cm.
