How do I solve 8/3=(y-9)/(7y+4)

Mathematics

Equation

\dfrac{8}{3} = \dfrac{y - 9}{7y + 4} Cross Multiply

Solve

8 * (7y + 4) = 3*(y - 9) Remove the brackets

56y + 32 = 3y - 27 Subtract 3y from both sides.

56y - 3y + 32 = - 27

53y + 32 = -27 Subtract 32 from both sides.

53y = -32 - 27

53y = - 59 Divide by 53

y = - 59/53

y = - 1.113

Check

8/3 = (-1.113 - 9)/(7*-1.113 + 4)

8/3 = -10.113 / (- 7.791 + 4 )

8/3 = -10.113 / -3.791

8/3 = 2.667 which very nearly right. Some rounding has taken place.

1101101+11011 in binary numbers please help
wel

Answer:

The answer is 1000 1000

Step-by-step explanation:

In HEX, it would be 88.

In DEC, it would be 136.

In Oct, it would be 210.

Binary, how to add numbers together.

     1101101

+       11011

10001000

This is just like adding regular numbers together.

For example, when you add 88 to 55, this is what will happen

   1(r)

  88

+ 55

13(+1)  3

143

With binary, when 1 and 0 are added together, the result is 1. When 1 and 1 are added together, the result is 1 and 0 (1 being the "remainder", or the number that is carried over. This number is then added to the next part of the number when adding, just like in normal addition.

Given circle P, which of the following options are major arcs?
MakcuM [25]

If your asking to select all that apply,

The formula is arc length = θ ( r ) {\displaystyle {\text{arc length}}=\theta (r)} , where equals the measurement of the arc's central angle in radians, and r {\displaystyle r} equals the length of the circle's radius. Plug the length of the circle's radius into the formula.

Y=2x+5 and y=3x+11 solve by substitution.
kondaur [170]

Answer:

Answer: x= -6 and y= -7

Step-by-step explanation:

Substitute 2x+5 for y in y=3x+11:

y=3x+11

2x+5=3x+11

2x+5+−3x=3x+11+−3x(Add -3x to both sides)

−x+5=11

−x+5+−5=11+−5(Add -5 to both sides)

−x=6

−x−1=6−1(Divide both sides by -1)

x=−6

Step: Substitute −6 for x in y=2x+5:

y=2x+5

y=(2)(−6)+5

y=−7(Simplify both sides of the equation)
