The answer is 4. This is how to solve the problem.

28>7h- Divide both sides by 7, due to the fact that 7 is being multiplied to the variable, which is in this case, the letter h.

7h divided by 7 is simply h. 28 divided by 7 is 4.

The final answer is 4>h. Please give me the brainliest answer. Thank you.

If 3/2+x/3=11/6,find x .

Lilit [14]

Step-by-step explanation:

$\frac{3}{2} + \frac{x}{3} = \frac{11}{6}$

$\frac{x}{3} = \frac{11}{6} - \frac{3}{2}$

$\frac{x}{3} = \frac{11 - 3 \times 3}{6}$

$\frac{x}{3} = \frac{11 - 9}{6}$

$\frac{x}{3} = \frac{2}{6}$

$\frac{x}{3} = \frac{1}{3}$

$x = \frac{3 \times 1}{3}$

$x = 1$

Find the equation of the line perpendicular to the<br> given line through the point (1,9). y=1/3x+5

Ivan

Slope-intercept form: y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be perpendicular, their slopes have to be the negative reciprocal of each other. (Basically flip the sign +/- and the fraction[switch the numerator and the denominator])

For example:

Slope = $\frac{1}{3}$

Perpendicular line's slope = $-\frac{3}{1}$ or -3

Slope = -2 or $-\frac{2}{1}$

Perpendicular line's slope = $\frac{1}{2}$

$y=\frac{1}{3} x+5$ The given line's slope is $\frac{1}{3}$ , so the perpendicular line's slope is -3. Now that you know the slope, substitute/plug it into the equation:

y = mx + b

y = -3x + b To find b, plug in the point (1, 9) and isolate/get the variable "b" by itself in the equation

9 = -3(1) + b Add 3 on both sides to get "b" by itself

9 + 3 = -3 + 3 + b

12 = b

y = -3x + 12
