Which word problems or inequalities could have a solution represented by the
number line?
Select all that apply.
A. Christopher has read for more than 32 minutes.
B. Christopher has read for less than 32 minutes.
C. Christopher has read for 32 minutes.
D. x < 32
E. x > 32
F. X = 32
Answer:
A -> E
B -> D
C -> F
Step-by-step explanation:
In all cases, we represent minutes that Christopher has read with variable x
Christopher has read for more than 32 minutes corresponds with the inequality: x > 32 ."More than" is equivalent to "greater than", which is symbolized by ">".
Christopher has read for less than 32 minutes, corresponds with the inequality: x < 32 . "Less than" symbolized by "<".
Christopher has read for 32 minutes corresponds with the equality: X = 32. Here the amount of time is fixed, so it agrees with an equality instead of an inequality.

Ava is making necklaces out of beads.
Ava bought 40
packages that each contain 100
beads.
Each necklace requires exactly 60
beads.
How many complete necklaces can Ava make?
Answer:
66 necklaces
Step-by-step explanation:
First determine how many beads Ava has
40 * 100 = 4000
Then divide by the number of beads per necklace
4000/60 =66.66666
Round down for complete necklaces

Shiva brought $37.00 to the art supply store. She bought a brush, a sketchbook, and a paint set. The brush was 1 3 as much as the sketchbook, and the sketchbook cost 1 2 the cost of the paint set. Shiva had $2.00 left over after buying these items. What was the cost of each item?
Answer:
b= 3.5
s= 10.5
p=21
Step-by-step explanation:
b for brush
s for sketch book
p for paint set
b=1/3s
s= 1/2 p
b+s+p=37-2
1/3 s +s+2 s =35
1/3 s +s +2 s =35
10/3 s=35
s= 35*3/10
s= 10.5
b=1/3 s = 10.5/3 = 3.5
s= 1/2 p so p= 2s = 2( 10.5) = 21
10.5+3.5 + 21 = 35
Solve the equation, –(x∕4) = 5, for x. Which of the following properties of equality did you apply? Question 7 options: A) Multiplication B) Multiplication and subtraction C) Division and addition D) Division
Answer:
A) Multiplication
The solution of given equation x= -20
Step-by-step explanation:
Step(i):-
Given equation - ( x /4) = 5
Multiply '-1' on both sides, we get
⇒ - ( (- x /4) ) = - 5
⇒ [tex]\frac{x}{4} = -5[/tex]
Step(ii):-
Multiply '4' on both sides, we get
⇒ [tex]\frac{x}{4} X 4= -5 X 4[/tex]
Cancellation '4' on left side , we get
x = -20
Conclusion:-

21. If the area of the plane shape below is
36cm, find its height.
Answer:
4 cm
Step-by-step explanation:
The figure is a parallelogram with area (A) calculated as
A = bh ( b is the base and h the perpendicular height )
Here A = 36 and b = 9 , thus
9h = 36 ( divide both sides by 9 )
h = 4 cm
Answer:
Step-by-step explanation:
considering the breadth of the shape as 5cm and length as 9cm...
now... for finding the height of the plane shape...
we need to use the formula for area of a trapezium...
so. area of a trapezium = 1/2 x height x sum of parallel sides
we are given area of trapezium = 36cm^2
SO SUBSTITUTING THE EQUATION...
36 = 1/2 x height x (9+9)
height = 4cm
help please would appreciate
Answer:
Ah! Thank you for a little challenge!
Step-by-step explanation:
To do this, we need to first find our new lengths!
Height= [tex]50+x[/tex]
Radius= [tex]20+x[/tex]
Now, to find the Volume!
Using the volume formula for a cylinder(v=pi*r^2*h)
[tex]v=\pi(20+x)^{2} (50+x)[/tex]
So, we have our equation! let's solve!
[tex]V=\pi*(x^{2}+40x+400)(50+x)\\V=\pi(x^{3} +90x^{2}+2400x+20000)[/tex]
Now, I'm guessing you had trouble with it because it looked really scary.
So what I did in the first step was expand (20+x)^2, and I used the special formula(forgot what else it was called, (a+b)^2=a^2+2ab+b^2)
Next, I multiplied the expand form of that with (50+x), and the way to do that is by multiplying each term in the parentheses with every term in the next parentheses(distributive property).
So, uh, that's it! Not very scary, just a bit of in-head math!

There is a group of $5$ children, where two of the children are twins. How many ways can I distribute $6$ identical pieces of candy to the children, if the twins must get an equal amount of candy?
Answer:
50
Step-by-step explanation:
Suppose that the kids get $x_1,x_2,x_3,x_4,x_4$ pieces of candy, respectively (each twin received $x_4$ pieces). Then we seek all quadruples $(x_1,x_2,x_3,x_4)$ satisfying
\[x_1+x_2+x_3+2x_4 = 6.\]We proceed by casework, based on the number of candies the twins receive.
If $x_4 = 0$, then there are 6 candies to distribute to 3 kids. This is like arranging 6 C's and 2 |'s (dividers), so there are $\binom{8}{2} = 28$ possible distributions.
If $x_4 = 1$, there are 4 candies remaining for the other 3 kids, so there are $\binom{6}{2} = 15$ possible distributions.
If $x_4 = 2$, there are 2 candies remaining, so there are $\binom{4}{2} = 6$ possible distributions.
If $x_4 = 3$, there are 0 candies remaining, for 1 possible distribution.
Adding all of these results from the separate cases, there are a total of
\[28 + 15 + 6 + 1 = \boxed{50}\].

Answer:
13 clay for each person
Step-by-step explanation:
Add all the clay to find the total.
15+10+13+14+13= 65 clay in total
There are 5 people in total.
Divide 65 by 5 to find the distribution for each person.

Answer:
c = 27
Step-by-step explanation:
If c divided by 9 equals to 3, then the other way around would be 3 times 9 equals to c, which is how you would get 27. If you look at PEMDAS, multiplication and division are together and work the other way around when used with each other, just like addition and subtraction.

What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of ∠ACB = measure of ∠BAC = 45°
And , the measure of ∠ABC = 90°
So , the triangle is a 45-45-90 triangle
Now , the measure of the sides be AB = BC = 1 unit
And , From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
The measure of side AC ( hypotenuse ) = √ ( AB )² + ( BC )²
The measure of side AC ( hypotenuse ) = √ ( 1 + 1 )
The measure of side AC ( hypotenuse ) = √2 units
Hence , the measure of the hypotenuse of 45-45-90 triangle is √2 units

|18-x|, if x<18. Pls help
Answer:
I18 - xI such that x < 18.
ok, first let's what happens if x = 18:
I18 - xI = I18 - 18I = 0
So, at the moment we have the condition:
I18 - xI > 0.
now, if x is a really large negative number, suppose, x = -100
I18 + 100I = I118I = 118
So, as x can freely move in the negative range, we can see that I18 - xI can be any positive number, so the only restriction that we have is:
I18 - xI > 0.
This means that the domain is:

Two bottles of water and three small bags of fruit cost a total of £2.55. If a bottle of water costs 15p more than a bag of fruit, what is the cost of a bag of fruit?
Answer:
The cost of a bag of fruit is 45p
Step-by-step explanation:
Let w be the number of water bottles.
Let f be the number of bags of fruits.
"Two bottles of water and three small bags of fruit cost a total of £2.55"
2w + 3f = 2.55
"a bottle of water costs 15p more than a bag of fruit"
w = 0.15 + f
Substitute the second formula to the first and solve.
2w + 3f = 2.55
2(0.15 + f) + 3f = 2.55
0.3 + 2f + 3f = 2.55
0.3 + 5f = 2.55
5f = 2.55 - 0.30
5f = 2.25
f = 2.25 ÷ 5
f = 0.45
Substitute to the second formula again and solve for w.
w = 0.15 + 0.45
w = 0.6
Now verify:
2w + 3f = 2.55
2(0.6) + 3(0.45) = 2.55
1.2 + 1.35 = 2.55
2.55 = 2.55 (Correct)
