Answer:
40.84 inches
Step-by-step explanation:
C=πd
C=π(13)
C=13π
C=40.84
So the pizza has a circumference of about 40.84 inches.
It's similar because u still with have an answer weather its a decimal or not. And it's different because when your multiplying whole number u will just get whole numbers.
Slope intercept form is: y=mx+b
So you take the first equation: 2x-3y=6 and you subtract the 2x from both sides and get: -3y= 2x+6
Then you take that equation: -3y= 2x+6 and divide -3 from both sides and get: y= -2/3x -2
So the equation 2x-3y=6 in slope intercept from is
y = -2/3x -2
Can you do the next one your self based on the one i did...?

Here ya go ;)
5x + 2y = 3 okay same steps as above you want to get the x on the other side so you subtract the 5x from both sides and get:
2y = 5x + 3
Then you want to get the y by its self so you divide the 2 from both sides so you get:
y = 5/2x +2/3
Now idk if your allowed to leave it like that (based on your teacher's preferance really) but if not you can simplfy your fractions and get:
y = 2.5x + 0.66
( i would leave the 2/3 and just leave it as y = 2.5x + 2/3 ) but you do you and i hope that helped you :)
X = 9
y = 6
Step by step:
Divide 15 by 2: 15 ÷ 2 = 7.5
Subtract 0.5 from 7.5 (this will later be added back): 7.5 - 0.5 = 7
Subtract 1 from 7 (she wants to buy at least 2 more children books): 7 - 1 = 6
Subtract 6 from 15 (6 being the number of puzzle books, 15 being the total number of items): 15 - 6 = 9 (number of children books)
If Quinn is included in the 35 friends the answer would be 35x126=4410.
