What is b - 3/16 = 5/16

Answers

If you would like to solve b - 3/16 = 5/16, you can do this using the following steps:

b - 3/16 = 5/16
b = 5/16 + 3/16
b = 8/16
b = 1/2

The correct result would be 1/2.

The solution to the equation b - 3/16 = 5/16 is b = 1/2.

To solve the equation b - 3/16 = 5/16, you need to isolate the variable b.

To eliminate the fraction, you can add 3/16 to both sides of the equation:

b - 3/16 + 3/16 = 5/16 + 3/16

Simplifying the equation:

b = 8/16

Now, you can simplify the right side of the equation:

b = 1/2

Therefore, the solution to the equation b - 3/16 = 5/16 is b = 1/2.

In basketball, Shaquille makes 40% of his free throw attempts. He goes to the free throw line to shoot one and one ( if he makes the first shot, he gets to shoot one more). He scores 1 point per free throw. What is the expected value of the number of points he will score?

Answers

Situations:
1) he makes 1st shot + he makes 2nd shot
P(A) = 0.4 · 0.4 = 0.16  ( 16 % )
2) he makes 1 st shot + he misses 2nd shot
P(B) = 0.4 · 0.6 = 0.24   ( 24 % )
3) he misses 1st shot and he has no more attempts
P (C) = 0.6 ( 60 %)
0.16 · 2 + 0.24 · 1 + 0.6 · 0 = 0.32 + 0.34 = 0.56
The expected value is 0.56 points.

.56 is the answer....

The sum of two numbers is 13. Two times the first number minus three times the second number is 1. If you let x stand for the first number and y for the second number, what are the two numbers?

Answers

x+y= 13 
2x-3y= 1
This can be found by using a system but I will try this method:
x=13-y
We replace it on the second one:
2(13-y) + y = 13
26-2y + y=13
-y= -13
y= 13

t = r + 13

VERY EASY QUESTIONMadison made a mistake when she combined terms. Explain what Madison did wrong? Explain and give an example of what she should have done.

What Madison did step by step:
7-3(4-2x)-10x
7-3(2x)-10x
7-6x-10x
7-16x

Answers

Her mistake is that she didn't distribute the terms correctly . She subtracted 4 and- 2x , which is incorrect . She had to multiply -3 and the numbers inside the parenthesis .
the mistake is in combining 4 with -2x because they're not like terms
7-3(4-2x)-10x
7-12-6x-10x
-5-16x
