Pat bounces a basketball 20 times in 30 seconds. At that rate, approximately how many times will Pat bounce the ball in 36 seconds?
A. 42 times
B. 28 times
C. 24 times
D. 32 times
Which one is right? Please explain your answer.
HELP ME PLS
The answer is B about 28 times
Step-by-step explanation:
If he bounces the ball 20 times in 30 seconds then he bounces it once every 1.5 seconds if you multiply 1.5×6 you get 9 so you add 9 to 20 to get 29 and you choose the closest answer because is says approximately so you chose B.28

10/5 = x-6/x+3 Please show your work!
Answer:
-12
Step-by-step explanation:
10/5 = x-6/x+3
2/1 = x-6/x+3
cross multiply
2(x + 3) = x - 6
2x + 6 = x - 6
collect like terms
2x - x = -6 - 6
x = -12.

Which expression represents a simplified form of the algebraic expression shown below?
1/2(2x +4) + x
Question 2 options:
x + 2
2x + 4
2x + 2
3x + 2
Answer:
2x+2
Step-by-step explanation:
First you want to distribute
1/2(2x+4)
ignore the ending +x for now
Distribute 1/2 to 2x
since 2*1/2 is 1 then we get 1x, or x
next distibute 1/2 to 4
you get +2 since 1/2*4=2
so what you end up with is x+2
However, you still have the +x from the beginning
x+2+x
Imagine that each x has a one in front
1x+2+1x
now re arrange so the common factors are near each other
1x+1x+2
now add the common factors
1x+1x=2x
and finally you get 2x+2

6 ÷ 2(1+2) ÷ 4(4+5) ÷ 6 =
Answer:
The answer to this equation is 7.5
Step-by-step explanation:
What I did is started with PEMDAS:
6÷2 (1 + 2) ÷4 (4 + 5) ÷ 6
^ ^
(3) (9)
Now the 3 and the 9 are what are in the ()
6÷2 = 3... 3 (3) = 9.
9 ÷ 4 = 5.
The 9 from earlier is still in parenthesis...
Take 5 and the 9 in parenthesis and multiply (If a single number is in (), It means to multiply anyway)
5 (9) = 45
The Final Step is to divide by 6
45 ÷ 6 = (FINAL) 7.5

Answer:
[tex]3\frac{3}{8}[/tex]
Step-by-step explanation:
6 ÷ 2(1+2) ÷ 4(4+5) ÷ 6 =
----------------------------------------
By order of operations, parentheis comes first.
6 ÷ 2*(1+2) ÷ 4*(4+5) ÷ 6 =
6 ÷ 2*(3) ÷ 4*(9) ÷ 6=
----------------------------------------
Next comes multiplication and division. Now, we can remove the parentheis and solve from left to right.
6 ÷ 2*(3) ÷ 4*(9) ÷ 6=
6 ÷ 2*3 ÷ 4*9 ÷ 6=
3*3 ÷ 4*9 ÷ 6=
9 ÷ 4*9 ÷ 6=

Sherry uses the steps below to solve the equation x + (negative 8) = 3 x + 6.
Step 1 Add 1 negative x-tile to both sides and create zero pairs
Step 2 Add 8 positive unit tiles to both sides and create zero pairs.
Step 3 Divide the 14 unit tiles evenly among the 2 x-tiles.
Step 4 The solution is x = 7
Answer:
b
Step-by-step explanation:
took the test. just trust
Add 8 positive unit tiles to both sides and create zero pairs.
The correct option is (B).
What is Algebra?The part of mathematics that helps represent problems or situations in the form of mathematical expressions.
Given:
x + (- 8) = 3 x + 6
x- 8 = 3x +6
First,
Add 8 positive unit tiles to both sides
x- 8 + 8 = 3x +6 + 8
x= 3x +14
The, creates pair
3x-x = -14
x= -7
Hence, Add 8 positive unit tiles to both sides and create zero pairs.

Answer:
[tex]m=8x-5-4\Delta x[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=4x^2-5x-1[/tex]
And we want to use the difference quotient:
[tex]m=\frac{f(x+\Delta x)-f(x)}{\Delta x}[/tex]
To find the slope function.
So, let's substitute [tex]x+\Delta x[/tex] for our function. This yields:
[tex]m=\frac{(4(x+\Delta x)^2-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]
Let's square. Use the perfect square trinomial pattern. This yields:
[tex]m=\frac{(4(x^2+2x\Delta x-\Delta x^2)-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]
Distribute:
[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)-(4x^2-5x-1)}{\Delta x}[/tex]
Distribute the right:
[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)+(-4x^2+5x+1)}{\Delta x}[/tex]
Combine like terms:
[tex]m=\frac{(4x^2-4x^2)+(-5x+5x)+(1-1)+(8x\Delta x-4\Delta x^2-5\Delta x)}{\Delta x}[/tex]
The first three terms will cancel. This leaves us with:
[tex]m=\frac{8x\Delta x-4\Delta x^2-5\Delta x}{\Delta x}[/tex]
We can factor out a Δx from the numerator:
[tex]m=\frac{\Delta x(8x-4\Delta x-5)}{\Delta x}[/tex]
The Δx will cancel. So, our slope function is:
[tex]m=8x-5-4\Delta x[/tex]
And we're done!
