A)In June a man

bought x balls
for $25 write down , in terms of
x the cost of each ball (in $)

b) In july he could have bought five more balls for the same amount of money. write down in terms of x the cost of each ball (in $)

c) given that each ball in july had cost 25 cents less. use your answers in a & b to form an equation in terms of x and show that it simplifies to x^2 +5x-500=0

d) solve the equation in (a)

e)hence , write down the number of balls bought in june

6 meters

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
