Simplify the exspression 3z+5+5z-5

8z

Step-by-step explanation:

3z+5+5z-5

Combine like terms

3z+5z   +5-5

8z +0

8z

8z

Step-by-step explanation:

all we have to do here is to combine like terms

so we can add 3z and 5z which would be 8z

then add 5 and -5 which would be 0

so the expression simplified would be 8z

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.

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
