Write an algebraic expression marlis brothers is x years older than her marli is 12? Plz I need helppp

12+x

Step-by-step explanation:

This is marli- []

Marli is 12

but lets say that Marli's brother is 5 yrs older than her just for fun

To find marli's  bro's age when her bro is 5 yrs older than her, we would add 5 and 12 right?

the same thing applies when there's a variable in place of a number

DO NOT GET CONFUSED, DO EXACTLY THE SAME THING IF THERE HAD BEEN A NUMBER INSTEAD OF A VARIABLE

so

marli's bro= 12+x

Hope This Helps

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
