Step-by-step explanation:
=8-5/3-4
=3/-1
=-3
Answer:
-3/1
Step-by-step explanation:
(3,8) 4,5)
5-8 divided into 4-3
-3/1
Mark the point (3,8) on the coordinate plan on graph paper. Then go 3 down,1 right, and you'll reach (4,5) (from left to right, from 3,8 to 4,5)
3 down means negative 3
1 right means positive 1

Answer:
C. 1/3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightStep-by-step explanation:
Step 1: Define
Identify
a = 2/3
b = 3/4
c = 1/2
a(b - c²)
Step 2: Evaluate
Substitute in variables: 2/3[3/4 - (1/2)²][Brackets] Exponents: 2/3(3/4 - 1/4)(Parenthesis) Subtract: 2/3(1/2)Multiply: 1/3Answer:
C. 1/3
Step-by-step explanation:
Replace each letter with their corresponding value and simplify using the order of operations:
a(b - c*c)
turns into:
[tex]\frac{2}{3} (\frac{3}{4}-(\frac{1}{2}*\frac{1}{2}))[/tex]
You want to remember that order of operations follows the rules of PEMDAS. The operations within the parentheses come first.
1/2 times 1/2 = 1/4
Now we have:
[tex]\frac{2}{3}(\frac{3}{4}-\frac{1}{4})[/tex]
Then 3/4 - 1/4 = 2/4 = 1/2
[tex]\frac{2}{3}(\frac{1}{2})[/tex] = 1/3
Therefore your answer is C. 1/3

104°
Answer:
∡1 = 64°
Step-by-step explanation:
∡3 = 180-104 which is 76°
∡1 = 180 - (40 + 76) = 180-116 or 64°
This question is about two positive numbers. Here are facts about these numbers:The numbers are consecutive even integers.The sum of the numbers is 38.
Now that we’ve learned how to solve word problems involving the sum of consecutive integers, let’s narrow it down and this time, focus on word problems that only involve finding the sum of consecutive even integers.
But before we start delving into word problems, it’s important that we have a good understanding of what even integers, as well as consecutive even integers, are.
Even Integers
We know that even numbers are integers that can be divided exactly or evenly by 22. Thus, the general form of the even integer nn, is n = 2kn=2k, where kk is also an integer.
In other words, since even numbers are the multiples of 22, we can represent an even integer nn by 2k2k, where kk is also an integer. So if we have the even integers 1010 and 1616,
Answer:
18 and 20
Step-by-step explanation:
x + x + 2 = 38
2x + 2 = 38
2x = 36
x = 18
x+2 = 20
find the mean and the median of the following data
number 1: 7, 6, 8, 12 ,15 ,7
number 2: 15 ,200 ,100, 130, 7
number 3: 60, 19, 12, 2 ,7 ,9
Answer:
Hope this helped! <3
Step-by-step explanation:
the median for number 1 is: 7.5 and the mean is 9.16667
the median for number 2 is: 100 and the mean is 90.4
the median for number 3 is: 10.5 and the mean is 18.16667
Answer:
Hi!
number 1: median: 8, 12 or 10
number 2: median: 100
number 3: median: 12, 2 or 7
number 1: mean: 9.16
number 2: mean: 90.4
number 3: mean: 18.16
Step-by-step explanation:
The mean is just all the numbers added up in a data set divided by how many numbers are in the data set. That gets you the average
The median is just the number in the middle of the data set.
Also for the first the median is either 10 or both 8 and 12 Because there's not 1 number in the middle it can be 8 and 12 of you want it averaged them it would be 10 I dont know which you want so you would have to figure that out
same with number 3
Also for the means it might vary depending if you need to round or not
If tests are worth 60% of your grade, and you have a 76.8% in that class, and you fail that test, what will be your grade?
Answer:
70
Step-by-step explanation:
it depends on the grade you make, so if you were to make a 65.47, your grade would be a 70, so any grade less than 70 should be the answer, hope this helps!

Step-by-step explanation:
The student put 5 in for y and 1 in for x. It should be x=5 and y =1
y = 3x+2
1 = 3*5 +2
1 = 15+2
1 = 17
This is not true so this is not a solution

At Anthony's school, 260 of the 500 students are girls. At Theresa's school, 360 of the 600 students are girls. Whose school has the greater percent of girls.
Answer:
Theresa school has greater % of girls
Step-by-step explanation:
Given
Number of girl in the Anthony school = 260
Total student in Anthony school = 500
% of girl in the Anthony school = 260/500 * 100 = 52 %
Number of girl in the Theresa school = 360
Total student in Theresa school = 600
% of girl in the Theresa school = 360/600 * 100 = 60%
Theresa school has greater % of girls
Three friends will run race. If three friends no ties, in how many distinct order can these 3 friends finish the race?
===========================================================
Explanation:
Let's name the friends A, B, C
If person A is first, then B or C could be second and third.
So we have ABC or ACB as two possible outcomes.
If B is first, then either A is second or C is second. Meaning we have BAC or BCA.
If C is first, then we have CAB or CBA
Overall here are the 6 different ways to have the runners finish
ABC ... A is firstACB ... A is firstBAC ... B is firstBCA ... B is firstCAB ... C is firstCBA ... C is firstNote how for the first slot we have 3 ways to pick the winner. Then after that selection is made, we have 2 choices left, then 1 choice for third place. Therefore, 3*2*1 = 6 different outcomes are possible.
We can use the factorial operation on the calculator to do this with one button press, so we'd say 3! = 6. The exclamation mark means "multiply from 3 down to 1, counting down the whole time".
Another example of a factorial is:
5! = 5*4*3*2*1 = 120

What is the value of A?
Answer:
a = 156
Step-by-step explanation:
24 and a form a straight line so they add to 180 degrees
24 +a = 180
Subtract 24 from each side
24+a-24 = 180-24
a = 156
Write an equation for the function that includes the points (1, 18) and (2, 54).
Answer:
y = 36x - 18
Step-by-step explanation:
(1,18) (2,54)
y2 - y1 / x2 - x1
54 - 18 / 2 - 1
36 / 1
= 36
y = 36x + b
18 = 36(1) + b
18 = 36 + b
-18 = b

the denominator of a rational number is greater then it's numerator is increased by 11 and the denominator is decreased by 1, the new number becomes 7/3. find the rational number.
Answer:
7/3
7 is increased by 11 so you decrease it by 11
7-11= -4
3 is decreased by 1 so you increase it by 1
3+1= 4
-4/4
In circle B with m
AC.
We need to find the angle measure of the minor arc which is [tex]\sf\widehat{AC}[/tex] . We note that the measure of a complete angle is 360 degree. So that ,
Using this :-
[tex]\sf : \implies \angle ABC + m\angle ABC = 360^o \\\\\sf: \implies 106^o + m\angle ABC = 360^o \\\\\sf: \implies m\angle ABC = 360^o - 106^o \\\\\sf: \implies \red{ m \angle ABC = 254^o }[/tex]
Hence the required answer is 254° .
Which expression is equivalent to 12n - 6x + 48 ?
A. 6 (2n - x + 8 )
B. 6nx +48
C. 2(6n + x ) +48
D. 12n - 6 (x + 4)
Answer:
A. 6 (2n - x +8)
Step-by-step explanation:
Answer:
6(2n-x+8)
Step-by-step explanation:
If a number is in front of the bracket it means times everything on the inside by that number.
So you times everything by 6.
6×2n=12n
6×-x= -6x
6×8=48
Then you put it into an equation:
12n-6x+48

Answer:
D
Step-by-step explanation:
According to the volume formula, you multiply length x width x height
Answer:
D; 1*9*4
Step-by-step explanation:
Since the formula for the volume of a rectangular prisim is L*W*H (length times width times height), it would be 9*4*1. However, since the order doesn't matter (due to the commutative property of multiplication) it would be D.
