If 13 is added to a number and the sum is doubled the result is -10 less than the number

Equation for solving: (13+x)2= -10-x

Step one: 26+2x=-10-x

step two: 26+3x=-10

step three: 3x=-36

-12

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

you would have to sell 24 bracelets.

step-by-step explanation:
