Hey, my sis can't register rn so I'm asking this question for her. She's learning PEMDAS and she was given 4 numbers, 18, 2, 3, and 4, and 3 symbols, ×, +, and ÷. She has to use PEMDAS and get to the number 12 at the end of it.

(18 + 2 * 3) / 3 + 4

Step-by-step explanation:

If you can’t use parentheses,

here is another solution:

18 + 3*4 / 3 + 2

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.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
