Answer:
14/45
Step-by-step explanation:
So we have the fraction:
We can do this algebraically. Follow to following steps:
Let's let this number equal to n. Thus:
Since there is only 1 digit repeating, let's multiply everything by 10. So:
Now, subtract n from both sides:
On the left, substitute the number for n. On the right, combine like terms:
All of the 1s will cancel. So:
Subtract:
Divide both sides by 9:
Remove the decimal by multiplying both sides by 10:
Reduce:
And we're done!

Answer:
The value of x is 14
Step-by-step explanation:
The value of x is 14 because the smaller triangle was dilated by 3 to get the bigger triangle. I figured this out because
9 ÷ 3 = 3
so this would mean that 5 was dilated by 3 also. So to figure this out, it would be
5 × 3 = 15
1 of that 15 is already there.
So this means that
15-1=14
A=14
I hope this helps you.
1- Leave the 1st case empty
2- Write on the 1st row each element of the trinomial in each case
3-Write on the 1st column in each case each of the element of the binomial
║ y² -3y 9
----------- ║-----------------------------------------------------
y ║ y³ -3y² 9y
----------- ║---------------------------------------------------
3 ║ 3y² -9y 27
------------║----------------------------------------------------
TOTAL║(y³+3y²) +(-3y²-9y) + ( 9y+27)
If you add the Total you will get: (A) Y³+27
X=amout the shirts cost
52=8+6.50+2x
add 8 and 6.5
52=14.5+2x
subtract 14.5 from 52
37.5=2x
divide 37.5 by 2
x=18.75
It cost $18.75 for each shirt.
