20x + 15 = 11

Step-by-step explanation:

First you need to add the like terms:

-7+2=-5

Now you need to expand the brackets:

-5*-4x=20x

-5*-3=15

Now you have 20x + 15 = 11. So if you want you can rearrange the formule to find x.

20x=-4

x= -5

There are 24 men and 36 women in a choir.

Molodets [167]

Answer:

Step-by-step explanation:

Total members in the choir = 24 + 36 = 60

a) Percentage of men = $\frac{24}{60}*100$

= 4 * 10 = 40%

b) Percentage of women = 60%

c) Number of men =24 + 10 = 34 men

Number of women = 36 + 10 = 46

Total = 34 + 46 = 80

Percentage of men = $\frac{34}{80}*100= 42.5$ %

Percentage of women = (100 - 42.5)% = 57.5%

Find the the slope of the line passing through points 2,2 and -1,0

scZoUnD [109]

For a given function, slope is defined as the change in outputs, or y-values divided by the change in inputs, or x-values. In essence the slope asks "For a given change in x, how much does y change?" or even more simply: "How steep is the graph of this function?". This can be represented mathematically by the formula: $slope=m=\frac{rise}{run}=\frac{\Delta y}{\Delta x}-\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substituting our known vlaues we have:
$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$m=\frac{2-0}{2-(-1)}$
$m=\frac{2}{3}$
