11.424242
isolate the repeating part
11+0.424242
focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242
subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99

so
5y-15x=-20
5y=15x-20
y=3x-20/3
Slope = 3
Slope Intercept Form
y-y1=m(x-x1)
Therefore y-(-6)=3(x-3)
y+6=3x-9
y=3x-15
Answer:
45
Step-by-step explanation:
split the shape in three parts, 3*5 + 6*4 + 3*4/2
Answer:
$1.25
Step-by-step explanation:
The graph shows that 3 pens cost $3.75 which means each pen costs more than $1 so we know that the greater number will be the numerator in our division equation. Divide 3.75 by 3 to get the unit rate.
3.75/3=1.25
Each pen costs 1.25
You can check your work by plugging it into the other points.
6*1.25=7.5 -So that second point is correct
9*1.25=11.25- The third point is also correct meaning we got the right answer
