Convert to denominators of 6:

21/6 + 14/6

Add the numerators:

35/6

Subtract from 8:

8 - 35/6

Convert 8 into a denominator of 6:

48/6 - 35/6

Subtract the numerators:

13/6

Convert to a mixed number:

2 1/6

So 2 1/6 of the board is left

First, add the two measurements up, then subtract it from 8.

3 1/2 + 2 1/3

Convert to improper fractions:

7/2 + 7/3

Convert to denominators of 6:

21/6 + 14/6

Add the numerators:

35/6

Subtract from 8:

8 - 35/6

Convert 8 into a denominator of 6:

48/6 - 35/6

Subtract the numerators:

13/6

Convert to a mixed number:

2 1/6

So 2 1/6 of the board is left.

The equation of a line is given below . 6x+2y =-18 find the x intercept and the y intercept
vova2212 [387]

Answer: x intercept is -3

y intercept is -9

Step-by-step explanation: 6(0) = 2y=-18, divide both sides by 2, get -9 as a y intercept

6x+2(0)=-18

divide both sides by 6, and get -3 as an x intercept

What is the length of arc S?<br> (The angle in the figure is a central angle in radians)
IgorC [24]

Answer:

π/90 or 0.0035 units

Step-by-step explanation:

equation: <em>length of the arc = ∠of the angle/360 * circumference</em>

Substitute: <em>S = 0.4/360 * 10π</em> --> C = 2πr

Simplify: S = 1/900 * 10π

Simplify: S = π/90 ≈ 0.003489 units

Find the equation of the line. Use exact numbers. y=y=y, equals x+x+x, plus
Nuetrik [128]

The equation of a line that is passing through the points (0, 4) and (1, 6) will be y = 2x + 4.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A coordinate plane. The x-axis and y-axis are each scaled by one.

A graph of a line goes through the points (0, 4) and (1, 6) will be

The equation of a line that is passing through the points (0, 4) and (1, 6) will be

y - 4 = [6 - 4 / 1 - 0] (x - 0)

y - 4 = 2x

    y = 2x + 4

The graph is given below.

More about the linear system link is given below.
