can i be brainiest...
Answer:
the answer is 14y
Step-by-step explanation:
this is because if you multiply 2xy it is 2y then multiply 2x3 and that's 6. Then you add 6+2y and get 8y. Next you multiply 2x4 which is 8 then 2xy which is 2y. Next you subtract 8-2y which is 6y. then you add 6y+8y and you answer is 14y.
A circular swimming pool is 40 inches in diameter. What is the circumference of the swimming pool?
Answer:
125.6 inches
Step-by-step explanation:
Diameter (d) = 40 inches
circumference (c)
= π * d
= 3.14 * 40
= 125.6 inches
Hope it will help :)
Answer:
125.6
Step-by-step explanation:
diameter= 40
40 x π = 125.6
40 x 3.14 = 125.6

2x + y = 9
x = y - 3
Answer:
x=2 and y=5
Step-by-step explanation:
Steps:
I will solve your system by substitution.
x=y−3;2x+y=9
Step: Solve x = y − 3 for x:
Step: Substitute y − 3 for x in 2x + y = 9:
2x+y=9
2(y−3)+y=9
3y−6=9(Simplify both sides of the equation)
3y−6+6=9+6(Add 6 to both sides)
3y=15
3y/3=15/3 (Divide both sides by 3)
y=5
Step: Substitute 5 for y in x = y − 3 :
x=y−3
x=5−3
x=2(Simplify both sides of the equation)
Answer:
x=2 and y=5
Answer:
x = 2 y = 5
Step-by-step explanation:
Since we know that
x = y - 3
We can insert that into the equation above:
2(y-3) + y = 9
After having this equation, we can start by multiplying the numbers/variables in the parenthesis by 2.
2y - 6 + y = 9
Then add the common multiples (2y and y)
That makes:
3y - 6 = 9
We need to get 3y on a side by itself, so to do this, we can add 6 to (-6) and (9)
That makes:
3y = 15
Divide the 3 by 3 and 15 to get the y on its own:
y = 5
Now we need to find x, and to do this we can insert y into the equation:
2x + 5 = 9
Now subtract the 5 from the (5) and (9) and you'll get
2x = 4
Then you divide the 2 on both sides and get
x = 2
You can check your work by inserting x and y into the equation
2(2) + 4 = 9

In a classroom of 30 students, in which 18 are girls and 12 are boys, what is the probability that two boys are selected without replacement by the teacher?
Answer:
about 4 out of 10
Step-by-step explanation:
Probabilities are used to determine the chances of events
The probability that two boys are selected is 0.1517
The given parameters are:
Boys = 12
Girls = 18
Total = 30
Given that the selection is without replacement, the probability that two boys are selected is:
p = 12/30 * 11/29
So, we have:
p = 0.1517
Hence, the probability that two boys are selected is 0.1517

suppose potatoes cost $0.99 per pound. complete the function rule c=? to describe the relationships between the total cost c and the number of pounds of potatoes p you buy.
Answer:
c=p*0.99
you gonna multiply the amt of patatoes by the cost of one to get the total like if you were buying 5 you would multiply 5 by 99 to get the total
P = $0.99
C = [tex]P * x[/tex]
[Note: x is how many pounds of potatoes you buy.]
