There was 1/3 of a box of cereal left four brothers shared it evenly write an equation to represent this problem
Answer:
1/12
Step-by-step explanation:
It is given that :
Amount of cereal left = 1/3 of a box
Number of people amongst whom the box of cereal is to be divided equally = 4
Therefore, an equation representing this problem is :
[tex]$\frac{1/3}{4} = x$[/tex]
where x = is the amount of the share each brother gets.
Therefore solving the equation, we get :
[tex]$\frac{1/3}{4} = x$[/tex]
[tex]$\frac{1}{3} \times \frac{1}{4} = x$[/tex]
[tex]$\frac{1}{12}=x$[/tex]
So, each brother got 1/12th of the cereal left.

What number makes the equation true?
Charlie is 4 more than twice as old as Frank. Frank is 3 years younger than Bob,
If Bob is 9 years old, how old is Charlie?
Answer:
16
Step-by-step explanation:
x + 3= 9
x = 6
2x + 4= 2*6 + 4
2x + 4 = 12 + 4
2x + 4 =16
Charlies 16
hope it helps
Answer: he is 16
Step-by-step explanation:
Let x = Frank's age
2x+4+ = Charlie's age
x+3+ = Bob's age
9 = Bob's age
x+3=9
x=6
2x+4=2⋅6+4
2x+4=12+4
2x+4=16
Charlie is 16

Step-by-step explanation:
A fair four-sided spinner has the numbers 1 to 4 marked on its sides. It is spun twice and the two scores are added together.
Answer:
Probability of getting doubles = 1/4
Step-by-step explanation:
Given - A fair four-sided spinner has the numbers 1 to 4 marked on its sides. It is spun twice and the two scores are added together.
To find - Using a sample space diagram, find the probability of getting a double.
Proof -
Given that,
A four-sided spinner is spin twice.
So,
The Sample Space becomes
S = { (1, 1), (1, 2), (1, 3), (1, 4)
(2, 1), (2, 2), (2, 3), (2, 4)
(3, 1), (3, 2), (3, 3), (3, 4)
(4, 1), (4, 2), (4, 3), (4, 4) }
So,
n(S) = 16
Now,
Let A is the event Getting a double, So,
A = { (1, 1), (2, 2), (3, 3), (4, 4) }
and
n(A) = 4
So,
The Probability of getting doubles = n(A) ÷ n(S)
= 4 ÷ 16
= 1/4
∴ we get
Probability of getting doubles = 1/4

Answer:
Blue: y = x² + 3
Purple: y = (x + 4)²
Step-by-step explanation:
The parabolas are "transformed", meaning they have been shifted on the coordinate grid. All parabolas will have the equation of "y = x²", any additional transformation will add onto that.
Blue: Looking at the red parabola, its lowest point is only three units down from the blue's lowest points. Meaning the blue parabola went only three units up. So you only have to do the "+ 3" in the equation.
Purple: Like in blue, we're gonna look at the purple's lowest point and compare it to red's lowest point. The purple parabola seems to have shifted only four units to the left. Though, instead of adding onto the equation like in the blue parabola, any changes on the x-axis will be put into parenthesis. IN ADDITION, the sign will be the opposite of what it is on the coordinate grid. For example, the purple parabola is on the -4 of the x-axis. Instead of putting "(x - 4)", we put "(x + 4)".
Try the next two problems on your own. They will be similarly structured to the two answers above. If you need more help, lemme know. :)

What inverse operation is used to solve the equation?
2x=10
Addition Property: add 2 to both sides
Division Property: divide both sides by 2
Multiplication Property: multiply both sides by 2
Subtraction Property: subtract 2 from both sides
Answer:
Division Property: divide both sides by 2
Step-by-step explanation:
[tex]2x = 10[/tex]
[tex] \frac{2x}{2} = \frac{10}{2} [/tex][tex]x = \frac{10}{2} [/tex][tex]x = 5[/tex]
Hope it is helpful....The sides of a square are all increased by 2 in. The area of the new square is 49 in.^2 . What is the length of a side of the original square?
2 in.
4.5 in.
5 in.
9 in.
Answer:
5
Step-by-step explanation:
square root is 49 is 7
so
1 side is 7
so
original side is 7 - 2
which is
5
Answer:
The original side length was 5 in.
Step-by-step explanation:
Area of new square is (side length)^2. Here,
that area is (x + 2)^2 = 49 in^2, and we must find x.
Taking the square root of both sides, we get:
x + 2 = +√49 = +7
Subtracting 2 from both sides yields x = -2 + 7 or x = 5
Check: does (5 + 2)^2 = 49? YES
Solve the system of equations. \begin{aligned} & -2x+15y = -24 \\\\ & 2x+9y=24 \end{aligned} −2x+15y=−24 2x+9y=24
Answer:
(12, 0)
Step-by-step explanation:
Given the system of equations;
-2x+15y = - 24 .....1
2x + 9y = 24 ....2
Using Elimination method
Add both equations
15y + 9y = -24 + 24
24y = 0
y = 0/24
y = 0
Substitute y = 0 into 2
From 2;
2x + 9y = 24
2x + 9(0) = 24
2x = 24
x = 24/2
x = 12
Hence the solution to the system of equation is (12, 0)
What is the equation of the line that passes through (4, 3) and (-4,-1)?
Answer:
[tex]\implies y = \dfrac{1}{2}x + 1 [/tex]
Step-by-step explanation:
Given :-
Two points (4,3) and (-4,-1)And we need to find out the equation of the line passing through the given two points .So here we can use the two point form of the line as ,
[tex]\implies (y - y_1) = \dfrac{y_2-y_1}{x_2-x_1}(x-x_1) [/tex]
Let us take that ,
[tex](x_1,y_1)=(4,3) [/tex][tex](x_2,y_2)=(-4,-1)[/tex]Now substitute the respective values ,
[tex]\implies (y -3) =\dfrac{3+1}{4+4}(x-4) \\\\\implies y - 3 =\dfrac{4}{8}(x-4) \\\\\implies y -3=\dfrac{1}{2}(x-4) \\\\\implies y -3=\dfrac{1}{2}x - 2 \\\\\implies y = \dfrac{1}{2}x +3-2\\\\\implies y = \dfrac{1}{2}x + 1 [/tex]
Hence the correct option is (2) .

If Z1 and Z4 are adjacent and
supplementary, what reason would
support this statement?
Statement
Reason
21 + 24 = 180° [? ]
A. Addition property of equality
B. Linear pair postulate
C. Adjacency theorem
Explanation:
As the name implies, "linear pair" means the two angles combine to form a straight line of 180 degrees. Think of gluing the angles together.
As an example, let's say angle 1 was 50 degrees and angle 4 is 130 degrees. They combine to 50+130 = 180 which is a straight angle. I recommend using a protractor to help draw these angles.
