Answer:

Step-by-step explanation:

You solve this problem by subtracting 3 from 10 because you have to solve it inversely. After doing this you get 7. Since that is 1/2 a number the number is 14

Answer:

Step-by-step explanation:

Let's call the number x.

$\dfrac{x}{2}+3=10$

Subtract 3 from both sides:

$\dfrac{x}{2}=7$

Multiply both sides by 2:

$x=14$

Hope this helps!

Find the slope of the line passing through the points (-5, 3) and (7, 9)

rodikova [14]

$\sf{\red{Answer}}$

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

$\sf{\purple{Explanation}}$

$\sf{m = \frac{y_{2}- y_{1}}{m_{2} - m_{1}} }$

$\sf{m = \frac{9- 3}{7- ( - 5)} }$

$\sf{m = \frac{6}{7 + 5} }$

$\sf{m = \frac{6}{12} }$

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

Solve the equation for P: 3k=7Q+6p

iren [92.7K]

3k=7Q+6p

Solve for P which means we have to make 'p' alone

$3k=7Q+6p\\\\ Add 7Q on both sides \\\\ 3k - 7Q = 7Q - 7Q + 6p\\\\ \left ( 3k - 7Q \right ) = 6p\\\\ Divide both side by 6 to make p alone \\\\ \frac{\left ( 3k - 7Q \right )}{6} = \frac{6p}{6}\\\\ p = \frac{\left ( 3k - 7Q \right )}{6}$
