Solve the equation 4/8y=8/3 for y
Solnce55 [7]

Answer:

y = \frac{16}{3}

Step-by-step explanation:

In order to solve for y, you need to isolate the y in the equation. Thus, to get rid of the \frac{4}{8} multiplied by the y, multiply both sides by the reciprocal, \frac{8}{4}. Then, reduce the fraction.

\frac{4}{8} y = \frac{8}{3} \\(\frac{8}{4} )\frac{4}{8} y = \frac{8}{3} (\frac{8}{4})\\y = \frac{64}{12} \\y = \frac{16}{3}

Thus, y = \frac{16}{3}.

What is porpotinal to 1/5
Irina-Kira [14]

An equation of the form y=ax+b, where y and x are variables, and a and b are constants, is called a linear equation.

The reason it is called linear is because the graph of the equation is a line.

The line passes through the origin only if b=0, as in our problem.

Any line (except vertical lines) represents a proportional relationship in that the change in y is proportional with the change in x. It is not a condition that the line passes through the origin.

In our specific case, y=(1/5)x, means that the change in y is always 1/5 of the change in x. That is, if x changes by 5 units, y changes by 1. If x changes by 10 units, y changes by 2, and so on.

So, the constant of proportionality is 1:5, or 0.2.

For the equation 6x-2y=8 <br> Write y in terms of x
Harrizon [31]
6x-2y=8

Subtract 6x from both sides
-2y=-6x+8
Divide both sides by-2

AleksAgata [21]

Answer:

∠D = 60

∠E = 99; x = 4

x = 32

Step-by-step explanation:

First things first, the sum of angles in a quadrilateral is 360°.

∠D + 120 + 95 + 85 = 360

∠D = 360 - 120 - 95 - 85

∠D = 60

∠E + 86 + 100 + 75 = 360

∠E = 360 - 86 - 100 - 75

∠E = 99

24x + 3 = 99

24x = 99 - 3

      = 96

x = 96 ÷ 24

x = 4

89 + 5x - 8 + 51 + 3x + 4 = 360

7x + 136 = 360

7x = 360 - 136

    = 224

x = 224 ÷ 7

x = 32
