Simplify the expression using the order of operations show all your work 150- (4²+4) ÷ 2
Answer:
65
Step-by-step explanation:
150-(4^2+4)/2
150-(16+4)/2
150-(20)/2
130/2=65
Answer:
140
Step-by-step explanation:
P: parenthesis
E: exponents
M: multiply
D: Division
A: add
S: subtract
150-(4^2+4)/2 exponent first 4^2= 4*4=16 you do this because it is
inside the parenthesis
150-(16+4)/2 you still have parenthesis so solve that next
150-20/2 next you divide because there is no multiplication
150-10 then subtract because there is no addition
140 is your final answer

Find the measure of each exterior angle.
Answer:
The answer is 137 degrees
Step-by-step explanation:
Add up the two angles you know already
93 + 44 = 137
Then you take that number and subtract it from 180 in order to find the other interior angle.
180 - 137 = 43
So angle LKJ is 43 degree
Now to find the exterior angle you take the missing angles measurement
Which is 43 and subtract it from 180 to get 137

is y=-3x+2 a function? why is it/is it not a function?
It is a function.
You can try plot the graph of that equation and then plot a vertical line. You will see that the graph will only intercept the vertical line only once. That is a function.
Or you can look at the equation. Functions have the equations that start with "y=". Rather say that if you see "y" only (not y² or y³ just only y) then that is mostly a function.
Write the word sentence as an equation. Then solve the equation.

Is anyone good with triangle inequalities? I provided a picture for the problem.
Answer:
1 < x < 19
Step-by-step explanation:
Triangle Inequality Theorem
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
We are given the measures y=10, z=9. The third side must satisfy:
10 - 9 < x < 10 + 9
1 < x < 19

\end{array}[/tex]
Step-by-step explanation:
The 2nd column of the table means that when x= -3, y= 6.
Since this table of values is for the equation of y= x² -x -6,
substitute the given values of x into the equation to find the respective values of y.
3rd column:
y= x² -x -6
When x= -2,
y= (-2)² -(-2) -6
y= 4 +2 -6
y= 0
4th column:
y= x² -x -6
When x= -1,
y= (-1)² -(-1) -6
y= 1 +1 -6
y= -4
6th column:
y= x² -x -6
When x= 1,
y= 1² -1 -6
y= 1 -1 -6
y= -6
7th column:
y= x² -x -6
y= 2² -2 -6
y= 4 -2 -6
y= -4
8th column:
y= x² -x -6
y= 3² -3 -6
y= 9 -3 -6
y= 0

The measure of the angle x in the right triangle is 67 degrees.
How to find the angle of a right triangle?A right angle triangle has one of its angles as 90 degrees.
The sum of angle in a triangle is 180 degrees.
Therefore,
x + 90 + 23 = 180
x + 113 = 180
x + 113 - 113 = 180 - 113

If you have $22 right now and $40 in the bank what % is the part you have from you total %62.
Answer:
35% on you
Step-by-step explanation:
22/62
Answer:
35.48% or 35.5% rounded
Step-by-step explanation:
So, let me just list the givens:
- You have $22 right now
- You have $40 in the bank
- You have a total of $62.
This is what we need to find:
- What percent is 22 of 62?
In order to get the what percent 22 is of 62, we need to divide 22 by 62.
[tex]\frac{22}{62} = .3548[/tex]
To change this to a percent we would move the decimal 2 times to the right so it will look like this:
.3548 --> 35.48%
Therefore, 20 is 35.48% of the total
I hope this is what you were asking for, if not let me know.

I NEED HELP!!! What is is this ----> 3x - 3y = 3 12x + 8y = -8
x = what
y = what
Answer:
3x = 3 + 2y -------------> 3x - 2y = 3 {subtracted 2y from each side of top equation}
(-4/3)x + y = -2/3 ------> -4x + 3y = -2 {multiplied bottom equation by 3}
3x - 2y = 3 ------> 12x - 8y = 12 {multiplied top equation by 4}
-4x + 3y = -2-----> -12x + 9y = -6 {multiplied bottom equation by 3}
12x - 8y = 12
-12x + 9y = -6
--------------
y = 6 {added the two equations}
3x = 3 + 2y {original top equation}
3x = 3 + 2(6) {substituted 6, in for y, into top equation}
3x = 3 + 12 {multiplied}
3x = 15 {added}
x = 5 {divided each side by 3}
x = 5 and y = 6

Wer +266. A bag contains $3$ balls labeled $2, 4$ and $8$. A ball is to be picked, the value on the label is to be recorded and then the ball is to be returned to the bag. This will be done three times and then the values will be added together. What is the sum of all of the possible distinct sums?
Answer:
The sum of all the possible distinct sum is 128
Step-by-step explanation:
The number of balls in the bag = 3
The ball labels, (the numbers written on the balls) = 2, 4, and 8
The number of balls selected with replacement = 1
Therefore, we have have, the number of ways of selecting 1 ball from 3 = 3 ways
The distinct combination of the selected balls are;
2, 2, 2 with sum 2 + 2 + 2 = 6
2, 2, 4 with sum 2 + 2 + 4 = 8
2, 2, 8 with sum 2 + 2 + 8 = 12
2, 4, 4 with sum 2 + 4 + 4 = 10
2, 4, 8 with sum 2 + 4 + 8 = 14
2, 8, 8 with sum 2 + 8 + 8 = 18
4, 4, 4 with sum 4 + 4 + 4 = 12
4, 4, 8 with sum 4 + 4 + 8 = 16
8, 8, 4 with sum 8 + 8 + 4 = 20
8, 8. 8 with sum 8 + 8 + 8 = 24
The distinct sums are therefore;
6, 8, 12, 10, 14, 18, 16, 20, 24
The sum of the distinct sum is 6 + 8 + 12 + 10 + 14 + 18 + 16 + 20 + 24 = 128.
Answer: 128
Step-by-step explanation:
Any sum formed by a combination of the numbers 2, 4, 8 and must be divisible by 2. The smallest possible value of such a sum is equal to 3*2=6 , and the largest possible value of such a sum is equal to 3*8=24 . After testing, we find that
6 = 2+2+2, 8=4+2+2, 10=4+4+2
12 = 4+4+4, 14 = 8+4+2, 16 = 8+4+4
18 = 8+8+2, 20 = 8+8+4, 24 = 8+8+8
However, we cannot find a combination that will add to be 22: if two of the numbers are not 8, then the maximum possible sum is 4+4+8 = 16. Thus, two of the numbers picked must be 8, but then the third ball must have the number 6, which is not possible. Thus, the answer is the sum of the even numbers from 6 to 24 excluding 22, which is 128 .
