"the number of blue markers in a drawer is 4 more than twice the number of red markers."
write an expression for the total number of markers in the drawer.
use only the variable r, which will represent the number of red markers

b=2r+4

Step-by-step explanation:

I don't think that you can do this using only one variable because there are two unknown amounts. Blue (b) is Red (r) multiplied by 2 plus 4 more, so the expression is b=2r+4.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
