Answer:
Option 4
Step-by-step explanation:
So we know that the area of a square is found by s^2. This means that we can just look for (6r)^2, since 6r is our side length! Let's see...We know that (6r)^2 is equal to 6^2 times r^2 because of the distributive property of exponents. Therefore, option 4 is our right answer. 36 is 6^2 and r^2 is r^2.
A rectangle is 12 cm long and 5 cm wide.
Work out the length of a diagonal of the rectangle.
Answer:
diagonal=13cm
Step-by-step explanation:
a² + b²=c²
(12cm)² + (5cm)²=c²
144cm² + 25cm²=c²
169cm²=c²
√169cm²=√c²
13cm=c

-x-6y=-18
-8x+y=3
What is the coordinates
Answer:
on a graph here is the answer
Step-by-step explanation:
Answer:
(0, 3 )
Step-by-step explanation:
Given the 2 equations
- x - 6y = - 18 → (1)
- 8x + y = 3 → (2)
Multiplying (2) by 6 and adding to (1) will eliminate the y- term
- 48x + 6y = 18 → (3)
Add (1) and (3) term by term to eliminate y , that is
- 49x + 0 = 0
- 49x = 0 , thus
x = 0
Substitute x = 0 into either of the 2 equations and solve for y
Substituting into (2)
- 8(0) + y = 3
y = 3
solution is (0, 3 )

Answer:
The value of x = 4
Step-by-step explanation:
Given the equation
[tex]5 + 9 = 6x - 10[/tex]
switch sides
[tex]6x-10=5+9[/tex]
Add 10 to both sides
[tex]6x-10+10=14+10[/tex]
Simplify
[tex]6x=24[/tex]
Divide both sides by 6
[tex]\frac{6x}{6}=\frac{24}{6}[/tex]
Simplify
[tex]x=4[/tex]
Therefore, the value of x = 4
Answer:
6x−10=5+9
6x−10=14
6x=14+10

A watercolor painting is 23 inches long by 11 inches wide. Ramon makes a border around the watercolor painting by making a mat that adds 1 inch to each side of the length and the width. What is the area of the mat?
Answer:
288 inches ²
Step-by-step explanation:
Water color painting
Length = 23 inches
Width = 11 inches
Mat that adds 1 inch to each side of the length and the width
Mat
Length = 23 + 1 = 24 inches
Width = 11 + 1 = 12 inches
What is the area of the mat?
Area of the mat = length × width
= 24 inches × 12 inches

What percent of 180 is 45?
4.5
18
22
25
Answer:
it is 25 hope this helped
Step-by-step explanation:
Hi there! :)
Answer:
The answer is D. 25% of 180 is 45.
Step-by-step explanation:
Let's replace "what percent" with the letter "x" because it's what we are looking for.
The word "of" is the same thing as a multiplication sign, which means that the sentence "What percent of 180 is 45?" can turn into "x times 180 is 45".
The word "is" is the same thing as an equation sign, wich means that you can write this as an equation:
x × 180 = 45
180x = 45
Now all you have to do is solve this equation by isolating "x" to find your answer:
180x = 45
Divide each side of the equation by 180 → 45 ÷ 180 = 0.25
x = 0.25
0.25 = 25 ÷ 100 = 25%
There you go! I really hope this helped, if there's anything just let me know! :D

こんにちは！ :)
回答：
答えはDです。180の25％は45です。
ステップバイステップの説明：
「何パーセント」を文字「x」に置き換えましょう。これが私たちが探しているものだからです。
「of」という単語は乗算記号と同じです。つまり、「180の何パーセントが45ですか？」という文です。 「x×180は45」になります。
「is」という単語は方程式の記号と同じものです。これは、これを方程式として記述できることを意味します。
x×180 = 45
180x = 45
今、あなたがしなければならないのはあなたの答えを見つけるために「x」を分離することによってこの方程式を解くことです：
180x = 45
方程式の各辺を180→45÷180 = 0.25で割ります
x = 0.25
0.25 = 25÷100 = 25％

The product of two consecutive odd numbers equals 55 plus ten times the even number which is between them. Find the even number.
Answer:
14
Step-by-step explanation:
The product of two consecutive odd numbers equals 55 plus ten times the even number which is between them. Find the even number.
Let the two odd consecutive integer be x and x+2
Let the even number between then be x+1
If the product of two consecutive odd numbers equals 55 plus ten times the even number, then;
(x)(x+2) = 55 + 10(x+1)
Expand
x² + 2x = 55 + 10x + 10
x² -8x -65 = 0
x² - 13x+5x - 65 = 0
x(x-13)+5(x- 13) = 0
(x-13) (x+5) = 0
x = 13 and -5
Since the even number is x + 1
Even number = 13 + 1 = 14

What is the measure of ∠ACV shown in purple?
Using the angle addition postulate, the measure of angle ACV shown in purple is given by:
<ACV = 224º.
What is the angle addition postulate?The segment addition postulate is a geometry axiom that states that an angle, divided into a number of smaller angles, has the measure given by the sum of the measures of the smaller angles.
For this problem, angle ACV is divided into:
Angle ACD.Angle DCV.Hence:
<ACV = <ACD + <DCV.
The measures are given as follows:
<ACD = 136º.<DCV = 88º.Hence the measure is given as follows:
<ACV = <ACD + <DCV = 136º + 88º = 224º.

Select all of the equations that have a solution of 4.
A.5x=20
B.8x-32
C.-4x=16
D.x/2=2
E.x/4=16
Answer:
a and d
Step-by-step explanation:
5x = 20
5/5x = 20/5
x = 4
8x = -32
x = -4
-4x = 16
x = -4
x/2 = 2
2*x/2=2*2
x = 4
x/4 = 16
4*x/4 = 16*4
x = 64
The equations 5x = 20 and x/2 = 2 are that have a solution of 4 which is the correct answer would be options (A) and (D).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have to determine the solution of all the given equations.
5x = 20
x = 20/5
Apply the division operation, and we get
x = 4
This is the required solution.
8x = -32
x = -32/8
Apply the division operation, and we get
x = -4
-4x = 16
x = 16/4
x = -4
x/2 = 2
2×x/2=2×2
x = 4
This is the required solution.
x/4 = 16
4×x/4 = 16×4
x = 64
Therefore, the correct answer would be options (A) and (D).
