Three equal-sized cardboard boxes are stacked on top of each other. Each box is 56.4 cm in height.
What is the combined height of the 3 stacked boxes?
18.8 cm
59.4 cm
112.8 cm
169.2 cm
Answer:
169.2cm
Step-by-step explanation:
56.4cm + 56.4= 112.8+ 56.4= 169.2cm
The combined height of the 3 stacked boxes will be 169.2 cm so option (D) will be correct.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given that,
Height of one box = 56.4 cm
So,
Height of two boxes = Height of one box + Height of one box
It means
Height of three boxes = Height of one box + Height of one box + Height of one box
So,
Height of three boxes = 56.4 + 56.4 + 56.4
Height of three boxes = 169.2 cm
Hence "The combined height of the 3 stacked boxes will be 169.2 cm".

Segment EC bisects segment AD at C. Find the value of “x," AD = 6x - 4 and AC = 4x - 3, and the measure of CD.
Answer: The value of x=1.
Measure of CD =1 unit.
Step-by-step explanation:
Given: Segment EC bisects segment AD at C.
That means , EC divided AD into two equal parts AC and CD,
i.e. [tex]AC=\dfrac{AD}{2}[/tex]
Also it is given that [tex]AD = 6x - 4[/tex] and [tex]AC = 4x - 3.[/tex]
then, we have
[tex]4x-3=\dfrac{6x-4}{2}\\\\\Rightarrow\ 4x-3= 3x-2\\\\\Rightarrow\ 4x-3x=-2+3\\\\\Rightarrow\ x= 1[/tex]
So, the value of x=1.
Now, CD = AC = 4(1)-3 =4-3 =1 unit.
Hence, Measure of CD =1 unit.

9(x+3)=4x-3 can you guys help look for x
Answer: x=-6
Step-by-step explanation:
9(x+3)=4x-3
9x+27=4x-3 ⇔ distributive property (take off parentheses)
5x+27=-3 ⇔ subtraction property of equality (subtract 4x on both sides)
5x=-30 ⇔ subtraction property of equality (subtract 27 on both sides)
x=-6
Hope this helps!! :)
Please let me know if you have any question
Answer:
simplify both sides and get 9x+27=4x+−3 then subtract 4x and get 5x+27=−3 and subtract -27 and divide answer by 5 to get x=-6

Camden is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 5 points. What would be Camden’s test score out of 50 if he got 2 questions wrong? What would be his score if he got x questions wrong
Answer:
1. 40 points2. 50-x pointsStep-by-step explanation:
1. Given that the total number of points is 50
2. Each question is worth 5 points
We can now calculate the number of questions by dividing the total points by the worth of each question
the number of question is = 50/5= 10
hence there are 10 questions available
if he misses 2 questions, which will amount to 10 points his score will be
50-10 = 40 points
Hence if he got x questions wrong his score will be
50-x points

Last Sunday a certain store sold copies of Newspaper A for $1.00 each and copies of Newspaper B for $1.25 each, and the store sold no other newspapers that day. If r percent of the store's revenue from newspaper sales was from Newspaper A and if p percent of the newspapers that the store sold were copies of Newspaper B. Write an expression in terms of r and p.
Answer:
[tex]\mathbf{r = \dfrac{400p }{ 500 -p}}[/tex]
Step-by-step explanation:
Given that:
Last Sunday a certain store sold copies of Newspaper A for $1.00 each
A = 1
and copies of Newspaper B for $1.25 each,
B = 1.25
and the store sold no other newspapers that day. If r percent of the store's revenue from newspaper sales was from Newspaper A and if p percent of the newspapers that the store sold were copies of Newspaper B.
Then ;
[tex]r = \dfrac{A}{A+1.25B} \times 100[/tex] --- (1)
[tex]p = \dfrac{A}{A+B} \times 100[/tex] --- (2)
From (2)
[tex]A+B = \dfrac{A}{p} \times 100[/tex]
[tex]B = \dfrac{A}{p} \times 100-A[/tex]
[tex]B = \dfrac{A( 100-p)}{p}[/tex]
Substituting the value of B into equation (1), we have:
[tex]r = \dfrac{A}{A+1.25 \times { \dfrac{A( 100-p)}{p}}} \times 100[/tex]
[tex]r = \dfrac{A}{A+1.25 \times { A( 100-p)}} \times 100p[/tex]
[tex]r = \dfrac{100p}{p+125 -1.25 p}[/tex]
[tex]r = \dfrac{100p}{125 -0.25 p}[/tex]
multiplying both numerator and denominator by 4; we have
[tex]r = \dfrac{4(100p) }{ 4(125 -0.25) p}[/tex]
[tex]\mathbf{r = \dfrac{400p }{ 500 -p}}[/tex]
Ashley is looking for ways to save some spending money for her senior class trip to Mexico. She has decided to
stop eating chocolate for one whole year and instead save any money she would have spent on chocolate for the
trip. If Ashley typically spends $2.50 a week on chocolate, how much money, not accounting for interest, can she
expect to save for the trip in exactly one year? $|||
Answer:
She would have 130 dollars
Step-by-step explanation:
There are 52 weeks in a year. So multiply 2.50 by 52. She would have 130 dollars.
Ashley can expect to save $130 for the trip in exactly one year.
Ashley decided to stop eating chocolate for one whole year to save some spending money for her senior class trip to Mexico.
The amount Ashley typically spends a week on chocolate = $2.50.
We have to find how much Ashley can save in one year if we can save $2.50 per week.
How many weeks in a year?There are 365 days in a year and we have 7 days in a week.
If we divide 365 by 7 we get,
365 / 7 = 52.14.
which means 52 weeks.
So in one year, we have 52 weeks.
We can write this statement "Ashley typically spends $2.50 a week on chocolate" as :
1 week = $2.50
Multiply by 52 on both sides.
we get,
52 x 1 week = 52 x $2.50
52 weeks = $130
Thus, we can say that in one year Ashley can save around $130 if she saves $2.50 in a week.

Write an equation of line in point slope form containing (-1,1) and (4,-9)
Help!!!!!!!!!!!!!!!!!
9Answer: Y-1=-2(X+1) OR Y+9 = -2(X-4)
Step-by-step explanation:
Point slope form is Y-Y1=m(X-X1)
Slope (M) is (Y2-Y1)/(X2-X1)
SO M= (-9-1)/(4--1)
-10/5
M= -2
Answer:
y - 1 = -2 (x + 1)
Explanation:
point slope form: (y - y1) = m (x - x1)
m is the slope. To find m the formula is:
(y2 - y1) / (x2 - x1)
The given ordered pairs are: (-1,1) and (4,-9)
y2 is the y in the second ordered pair (-9)
y1 is y in the first ordered pair (1)
x2 is x in the second ordered pair (4)
x1 is x in the first ordered pair (-1)
= (-9 - 1) / (4 +1)
= -10/5
m = -2
Now plug m (-2), y1 (1), and x1 (-1) into the point slope form
y - 1 = -2 (x - -1)
y - 1 = -2 (x + 1)

4+x= 3(x + 2) - 2x
I really don’t get how to this at all like I really don’t get it I need some help
Answer:
no solution
Step-by-step explanation:
Given
4 + x = 3(x + 2) - 2x ← distribute and simplify right side
4 + x = 3x + 6 - 2x
4 + x = x + 6 ( subtract 4 from both sides )
x = x + 2 ( subtract x from both sides )
0 = 2 ← not possible
This indicates the equation has no solution

Answer:
32
Step-by-step explanation:
We are given the expression:
[tex]\frac{-8(13-37)}{6}[/tex]
and asked to evaluate the expression.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve inside the parentheses first. Subtract 37 from 13.
⇒ 13-37= -24
[tex]\frac{-8(-24 )}{6}[/tex]
Next, multiply -8 and -24.
⇒ -8*-24= 192
[tex]\frac{192}{6}[/tex]
Finally. divide 192 by 6.
⇒ 192/6 = 32
[tex]32[/tex]
When evaluated, the expression -8(13-37)/6 is equal to 32.

Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
r = [tex]\frac{5}{8}[/tex] t - 9 ← is in slope- intercept form
with y- intercept c = - 9
Function 2 has the ordered pair (0, - 9 )
This indicates that when t = 0 , r = - 9
This is the y- intercept at - 9
Thus both functions have the same y- intercept

what values of a and b would make shown below have infinitely many solutions aX +6=-3x+b
Answer:
a = -3, b = 6
Step-by-step explanation:
ax + 6 = -3x + b
If a = -3 and b = 6, then the equation would be -3x + 6 = -3x + 6, which would have infinitely many solutions.
If we isolate x, we have (a + 3) x = b - 6. We want the equation to be 0 = 0 for infinitely many solutions, so a has to be -3 and b has to be 6.
