Answer: 6x*9
Step-by-step explanation:
open parathesises to
x+1*x-3*x+4*3x+7
combine like terms
6x*9
you can’t simplify further so bam
hope i did this right and it helps :)
3/12 is a rational number because rational numbers can be written in the form of a/b
When you simplify 3/12, you get 1/4, which is a fraction
Y=12+2x
y represents the number of pieces she now knows, x represents the number of weeks she has taken lessons, 2 is the slope (the number of pieces she'll learn each week), and 12 is the y intercept (the number of pieces she knew before taking lessons).
To solve the equation for 11 weeks, we replace x with 11.
2×11+12= 24
y=24
