11 + 22x = 9 + 30x
(Please provide the steps to complete the equation)
Answer:
x = 4
PLS LOOK AT THE PIC I HAVE SENT YOU, HOPE THIS WILL HELP YOU!
Answer:
x = 1/4
Step-by-step explanation:
11 + 22x = 9 + 30x
subtract 22x from both sides
11 = 9 + 8x
subtract 9 from both sides
2 = 8x
divide both sides by 8
2/8 = x
simplify
1/4 = x

Step-by-step explanation:
(-32)^-1.2
*answer needs to be in fraction form*
Answer:
[tex]\dfrac{1}{64}[/tex]
Step-by-step explanation:
[tex](-32)^{-1.2} = \dfrac{1}{(-32)^{\frac{6}{5}}} = \dfrac{1}{(\sqrt[5]{-32})^6}} = \dfrac{1}{(-2)^{6}} = \dfrac{1}{64}[/tex]
How do you figure this out?
Let the red cat be represented by x.
Let the yellow cat be represented by y.
Let the white cat be represented by z.
Which means :
[tex] \tt (1) \: \frac{4}{5} (20x - 5)[/tex]
[tex]\tt = \frac{4}{5} \times 20x - \frac {4 }{5} \times 5[/tex]
[tex] \tt= \frac{80x}{5} - \frac{20}{5} [/tex]
[tex]\tt = 16x - 14[/tex]
Thus, the first statement is correct.
[tex]\tt(2) \: \frac{3}{5} ( \frac{1}{3} z - 10)[/tex]
[tex]\tt = \frac{3}{5} \times \frac{1}{3} z - \frac{3}{5} \times 10[/tex]
[tex]\tt = \frac{3}{15} z- \frac{30}{5} [/tex]
[tex]\tt = \frac{1}{5} z - 6[/tex]
Thus, the second statement is a lie.
[tex]\tt(3) \: \frac{1}{9} ( - 9y - 27x)[/tex]
[tex] \tt= \frac{1}{9} \times - 9y - \frac{1}{9} \times 27x[/tex]
[tex]\tt = \frac{ - 9}{ \: \: 9} y - \frac{27}{9} x[/tex]
[tex]\tt = (- y) - 3x[/tex]
Thus, the third statement is correct.
Therefore, the second one is a lie.
Answer:
Let the money with Miguel be x.
Then :
Money with Kira = x - 9
Money with Charlie = 4x
Total money in their wallet = $105
This can be written in an equation as :
= \tt \: x + x - 9 + 4x = 105=x+x−9+4x=105
= \tt2x + 4x - 9 = 105=2x+4x−9=105
= \tt 6x - 9 = 105=6x−9=105
= \tt6x = 105 + 9=6x=105+9
= \tt6x = 114=6x=114
= \tt x = \frac{114}{6}=x=
6
114
= \tt x = 19=x=19
Which means :
Money with Miguel = $19
Money with Kira :
= 19 - 9
Thus, Kira has $10 in her wallet.
Money with Charlie :
= 4 × 19
= 76
Thus, Charlie has $76 in his wallet.
Therefore,
Money with Kira = $10
Money with Charlie = $76
Money with Miguel = $19
∠A and \angle B∠B are complementary angles. If m\angle A=(2x-10)^{\circ}∠A=(2x−10) ∘ and m\angle B=(x-2)^{\circ}∠B=(x−2) ∘ , then find the measure of \angle A∠A.
Answer:
118°
Step-by-step explanation:
Two angles are called complementary when their measures add to 90 degrees.
From the question,
Angle A=(2x-10)°
Angle B=(x-2)°
Both Angles are complementary.
Therefore
Step 1
(2x - 10)° + (x - 2)° = 180°
2x + x - 10 - 2 = 180°
3x - 12 = 180°
3x = 180° + 12
3x = 192°
x = 192/3
x = 64°
Step 2
We are to solve for Angle A
(2x-10)°
Angle A = 2(64 ) - 10
Angle A = 128 - 10
Angle A = 118°
The measure of Angle A = 118°

The table above shows the height of a plant
at the end of each week. The height
increases by the same amount each week. If
this pattern continues, what will be the
height, in inches, of the plant at the end of
the 7th week?
(A) 1.25 in
(B) 1.50 in
(C) 1.75 in
(D) 2.00 in
Answer:
(C) 1.75 in
Step-by-step explanation:
It give you a clue in the question that the height increases by the same amount each week. This means that if you add 0.25 you will get a constant answer. What I mean by constant is this :-
0.25 + 0.25 = 0.5 in
I can also do it by multiplying it by 2.
2 × 0.25 = 0.5 in
If you add 0.25 every time or if you multiply 0.25 by the number of weeks you will get your answer same. So,
7 × 0.25 = 1.75 in
Hope this helps, thank you !!

When x = 0.8, D. is correct
2.01 > 2.5(0.8)
2.01 > 2 √
Answer:
D.

What are the zeros of f(x)=(x+5)(x-9)?
Answer:
x= -5
x= 9
Step-by-step explanation:
Answer:
x = - 5, x = 9
Step-by-step explanation:
To find the zeros equate f(x) to zero, that is
(x + 5)(x - 9) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 9 = 0 ⇒ x = 9

solve for x joe thank you Joe Joe mama
The first step that we must take before attempting to solve almost any problem is to determine what the problem statement is asking us to do and what they are giving to us to help finish the problem. Looking at this question we can see that they have requested for us to solve for x and we were provided with a figure.
After understanding what the problem is asking for us to do we can attempt to solve the problem. We can see that there are two angles on a straight line and this is known as supplementary angles. Let us define what supplementary angles are.
Supplementary Angles ⇒ Supplementary Angles are two angles that are formed on a straight line causing them to add up to 180 degrees. Therefore, an expression can be made where the two angles add up to 180 and it can be solved for the unknown.In this case we don't have a missing angle but rather a variable that makes up each of the angles. Using a similar concept we can create an expression with 4x - 6 and 2x and have them combined to equal to 180. After that we can solve for the unknown which in turn would give us x.
Create an expression
[tex]Angle_1 + Angle_2 = 180[/tex][tex](2x) + (4x - 6) = 180[/tex]Combine like terms
[tex]2x + 4x - 6 = 180[/tex][tex](2x + 4x) - 6 = 180[/tex][tex](6x) - 6 = 180[/tex]Add 6 to both sides
[tex](6x) - 6 + 6 = 180 + 6[/tex][tex](6x) = 180 + 6[/tex][tex]6x = 186[/tex]Divide both sides by 6
[tex]\frac{6x}{6} = \frac{186}{6}[/tex][tex]x = \frac{186}{6}[/tex][tex]x = 31[/tex]Therefore, after creating an expression and then simplifying it down all the way to just have the value of x equal to something we were able to determine that the unknown variable of x is equal to 31.
[tex]\huge\text{Hey there!}[/tex]
[tex]\text{Your equation: }\rm{(2x) + (4x - 6) = 180^\circ}\\\large\text{SOLVING for the x-value}\\\rm{2x + 4x - 6 = 180^\circ}\\\large\text{COMBINE the LIKE TERMS}\\\rm{(2x + 4x) + (-6) = 180^\circ}\\\rm{2x + 4x - 6 = 180^\circ}\\\rm{6x - 6 = 180^\circ}\\\large\text{ADD 6 to BOTH SIDES}\\\rm{6x - 6 + 6 = 180 + 6}\\\large\text{SIMPLIFY IT!}\\\rm{6x = 180 + 6}\\\rm{6x = 186}\\\large\text{DIVIDE 6 to BOTH SIDES}\\\rm{\dfrac{6x}{6} = \dfrac{186}{6}}\\\large\text{SIMPLIFY IT!}\\\rm{x = \dfrac{186}{6}}\\\rm{x= 31}[/tex]

Today, Reza ate 20 grapes, which was 400% as many
grapes as he ate yesterday. Explain how to use
equivalent ratios to find the number of grapes Reza ate
yesterday. (help plz)
its not a sin to want to win cant see meflying like a bee i see a dreamer other there by the water but i
LOL
Answer:
What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.
To do it, let:
x: number of grapes that Reza ate yesterday
(x / 20) = (100/400).
Clearing x we have:
x = (100/400) * (20) = 5
answer
the number of grapes Reza ate yesterday was 5

Answer:
Assuming you're talking about the angles of a triangle, X would be [tex]34^{.}[/tex]
Step-by-step explanation:
The sum of the angles in a triangle is 180, 180 - 32 - 80 = 68, [tex]\frac{68}{2}[/tex] is 34, so X is equal to [tex]34^{.}[/tex].
the following cylinder has a volume of 55pi cubic units and a height of 5 units. the cone has the same base area and height, and it has a slant height of 6 units. what is the volume of the cone?
Question:A cone and a cylinder have the same base area. They also have the same curved surface area. If the height of the cylinder is 3m, then the slant height of the cone (in m) is
Answer:
Given the radius of cylinder and cone are the same because there base areas are same.
Curved surface of cylinder = curved surface area of the cone
∴2πrh=πrl
∴l=2h
Given, height of cylinder =3 cm
Therefore, slant height of cone =6 cm
The volume of the cone is 22π.
How to calculate the volume?Volume of a cylinder = πr²h
55π = πr²(5)
55π = 5πr²
r² = 55π/5π
r² = ✓11
r = 3.3
The volume of the cone will be:
= 1/3πr²h
= 1/3 × π × 3.3² × 6
= 1/3 × 11 × 6 × π
= 22π
