Masja [62]3 years ago

Answer:

Step-by-step explanation:

It is hard to read but (5x - 2) + (7x - 9)  =  AC    also  5x - 2   =   7x - 9

    5x - 2 = 7x - 9         subtract 5x from both sides then add 9 to both sides

5x - 5x - 2 + 9  = 7x - 5x - 9 + 9

   -2 + 9 = 7x - 5x

          7  =  2x

        3.5  =  x

    5x - 2 = 7x - 9    

         3   ≠    -2                        when x = 1

         8   ≠     5                        when x = 2

        13   ≠    12                        when x = 3

     15.5   =    15.5                     when x = 3.5

        18   ≠    19                        when x = 4

How do you do this question? 24 is what percent of 32?
Eddi Din [679]
24 = x% * 32

24= x/100 * 32

Multiply 100 on both sides.

2400 = x * 32

32x = 2400

Divide 32 on both sides.

x = 2400/32

x = 75


75 percent<span> of 32 is 24</span>

Here's the rest of my points for anyone who wants them :)
kramer

Answer:

7

Step-by-step explanation:

line in the middle is an angle bisector

14/6 = 21 / 3x - 12

first, cross multiply

14 (3x - 12) = 6*21

Remove the brackets

42x - 168 = 126

Add 168 to both sides

42x = 168 + 126

Combine

42x = 294

Divide by 42

x = 294/42

x = 7

Pavlova-9 [17]

Answer:

f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)

Step-by-step f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)explanation:

f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)f(x) f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)p(x + 1) – c, then (α + 1)(β + 1)f(x) = x2 – p(xf(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1) + 1) – c, then (α + 1)(β + 1)f(x) = x2 – p(xf(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1) + 1) – c, then (α + 1)(β + 1)f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)
