Solve for c: c=5 5/6 x 2

Marina86 [1]

Hi there!

c=11 2/3

1.Convert 5 5/6 into mixed number:

$5 \frac{5}{6}=\frac{35}{6}$

2.Convert 2 into fraction term:

$2=\frac{2}{1}$

3.Convert both fraction into same denominator:

$\frac{35}{6}=\frac{35}{6}$

$\frac{2}{1}=\frac{12}{6}$

4.Multiply the two terms:

$\frac{35}{6}$ · $\frac{12}{6}=\frac{70}{6}$

5.Simplfly the fraction term:

$\frac{70}{6}=\frac{35}{3}$

$\frac{35}{3}=11 \frac{2}{3}$

Therefore, c=11 2/3.

A given line has the equation 2x + 12y = −1.

ludmilkaskok [199]

2x + 12y = -1
12y = -2x - 1
y = - 1/6x - 1/12...slope here is -1/6. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So our perpendicular line will need a slope of 6.

y = mx + b
slope(m) = 6
(0,9)...x = 0 and y = 9
sub and find b, the y int
9 = 6(0) + b
9 = b

so ur perpendicular equation is : y = 6x + 9 <==
