Answer:
C.
Step-by-step explanation:
Your fractions are missing there fraction bars:
3/4 (20y − 8) + 5 = 1/2 y + 1/4 (20y + 8)
15y − 6 + 5 = 1/2 y + 5y + 2
15y − 1 = 11/2 y + 2
A. 11/2y and 2 aren't like terms because one contains the variable y and the other contains no variable
B. The distribute property can't be used there because you don't have 15(y-1) you have 15y-1
C. Subtracting 11/2y sounds like a good step because there is a y term on the opposing side.
15y-1=11/2y+2
Subtracing 11/2y on both sides
9.5y-1=2
That looks pretty good because then you would add 1 on both sides giving:
9.5y =3
Last step would get the y by itself which is dividing both sides by 9.5 giving you 6/19.
D. You could actually do this but it doesn't help you get x by itself. The equation would look like this: 15/2 y-1/2=11/4 y+1
Answer:
(0, - 3 )
Step-by-step explanation:
the solution to the system is at the point of intersection of the graphs.
the graphs intersect at (0, - 3 )
then solution is (0, - 3 )

Answer:
7.5
Step-by-step explanation:
If we look at the 4 by 4 square around the triangle we can just do the area of the square minus the area of the 3 little triangles which is:
4 * 4 - 4 * 1 / 2 - 3 * 3 / 2 - 4 * 1 / 2
= 16 - 2 - 4.5 - 2
= 16 - 8.5
= 7.5
Answer:
+5.20 µC
Explanation:
Given that
Charge =−5.20 µC and radius= 5.40 cm.
Insert a +10.4- µC charge at the center of the sphere
As we know that according to Gauss's theorem electric field inside the metal is zero.
When +10.4 µC charge insert but the total charge on the sphere should be −5.20 µC.So the charge on the outer surface of the sphere will be +5.20 µC.
