Answer:
four
Step-by-step explanation:
the associative property is when what ever is in the parentheses can be moved around and it won’t matter because I’ll give the same answer. One dosent have parenthese, two does but the x will distribute into the equation, three there is no parentheses, and four has parentheses and you can’t distribute.

A rectangle has a perimeter of 38+x 38+x centimeters. The rectangle has a length of 3x−2 3x−2 centimeters and a width of x centimeters. What is the length of the rectangle? A. Substitute the dimensions of the rectangle info the perimeter formula P=2w+2l P=2w+2l b. Solve for x. C. Find the length of the rectangle.
Answer:
The length of the rectangle is 6 centimeters
Step-by-step explanation:
The perimeter of a rectangle =
P = 2L + 2W
A rectangle has a perimeter of 38+x centimeters. The rectangle has a length of 3x−2 centimeters and a width of x centimeters.
Hence:
38 + x = 2(3x - 2) + 2(x)
38 + x = 6x - 4 + 2x
Collect like terms
38 + 4 = 6x + 2x - x
42 = 7x
x = 42/7
x = 6 centimeters
The length of the rectangle is 6 centimeters
help me find x is this question
Answer:
12.25
Step-by-step explanation:
You have to work it out like if it was a ratio.
basically you need to make 7/x equal to 4/7
to do this you divide 4 by 7 and the divide 7 by the answer. This will make x equal to 12.25

PLEASE GIVE ME AN ANSWER QUICKLY! Hiroshi spends 30 minutes on history homework , 60 minutes on English homework, and x minutes on math homework. One fourth of his total homework time is spent on math. Which equation can be used to find the amount of time Hiroshi spends on his math homework?
A. 1/4 (x+30+60)=x
B. 1/4 (x)=x(30+60)
C. 1/4x(30+60)=x
D. 1/4(x)=(30+60)
Answer:
A
Step-by-step explanation:
He spends:30 mins on History60 mins on Englishx mins on mathso the total time he spends is [tex](TotalTime)minutes=(30+60+x)minutes[/tex] one fourth of this is his math time, since x is math time, then we have [tex]\frac{1}{4}(TotalTime)minutes=(x)minutes[/tex] But we know what totaltime in minutes is so [tex]\frac{1}{4}(30+60+x)minutes=(x)minutes[/tex] or simply: [tex]\frac{1}{4}(30+60+x)=x[/tex]n − 23 ≥ 19 solve the inequality
Answer:
N greater than or equal to 42
Step-by-step explanation:
You have to look at the equation and then add 23 to both of the sides. After you will get 42 and drop down everything.

The ice cream shop sells sundaes for $2 each and banana splits for $3 each. One day, the shop sold 8 more sundaes than banana splits and also made a total of $156. Which system of equations represents the situation?
Answer:
[tex]s = 8+b\\2s+3b=156[/tex]
Step-by-step explanation:
To find which systems of equation represents the situation, we can break down the key information and create two variables:
Variables:
Let [tex]s[/tex] = number of sundaes sold.
Let [tex]b[/tex] = number of banana splits sold.
Given information:
Sundae: [tex]\$2[/tex]
Banana Splits: [tex]\$3[/tex]
8 more sundaes sold than banana splits. This can be expressed by [tex]s=8+b[/tex].
Total sold was [tex]\$156[/tex]. This can be expressed as [tex]2s+3b=156[/tex].
∴ The systems of equation that expresses this situation are [tex]s=8+b[/tex] and [tex]2s+3b=156[/tex].
Hope this helps :)

Jane made a mistake when writing down a mutliplication , and she multiplied by 54 instead of 45. Her answer was 198 more than it should have been. What number did she multiply 54 by?
Answer:
22
Step-by-step explanation:
Given that:
Let number multiplied by 54 = x
Let output = y
x * 54 = y + 198
x * 45 = y
54x = y + 198 - - - (1)
45x = y - - - (2)
Put y = 45x in (1)
54x = 45x + 198
54x - 45x = 198
9x = 198
x = 22
Number multiplied by 54 is 22

give the new coordinates. Square WXYZ with vertices W(1,7), X(6,5),
Y(4,0), and Z(-1, 2): (x, y) = (x-7, y-6)
Given:
The vertices of square WXYZ are W(1,7), X(6,5), Y(4,0), and Z(-1, 2).
Consider the rule of transformation is [tex](x, y)\to (x-7, y-6)[/tex].
To find:
The new coordinates.
Solution:
We have,
[tex](x, y)\to (x-7, y-6)[/tex]
Using the above rule of transformation, we get
[tex]W(1, 7)\to W'(1-7, 7-6)=W'(-6,1)[/tex]
[tex]X(6, 5)\to X'(6-7, 5-6)=X'(-1,-1)[/tex]
[tex]Y(4, 0)\to Y'(4-7, 0-6)=Y'(-3,-6)[/tex]
[tex]Z(-1, 2)\to Z'(-1-7, 2-6)=Z'(-8,-4)[/tex]
Therefore, the new vertices are W'(-6,1), X'(-1,-1), Y'(-3,-6) and Z'(-8,-4).

I start with 100 and subtract 3 repeatedly. (100 - 3, 97 - 3, 94 - 3 and so on). How many subtractions would I have to do to get the FIRST single-digit number?
Using an arithmetic sequence, it is found that you would need to do 32 subtractions
In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem:
Starts with 100, which is the first term, hence [tex]a_1 = 100[/tex].Subtracts 3, which is the common difference, hence [tex]d = 3[/tex]Then:
[tex]a_n = a_1 + (n - 1)d[/tex]
[tex]a_n = 100 - 3(n - 1)[/tex]
[tex]a_n = 103 - 3n[/tex]
To get a single-digit number, we need that:
[tex]a_n \leq 9[/tex]
Hence, solving the inequality:
[tex]103 - 3n \leq 9[/tex]
[tex]-3n \leq -94[/tex]
[tex]3n \geq 94[/tex]
[tex]n \geq \frac{94}{3}[/tex]
[tex]n \geq 31.3[/tex]
Rounding up, 32 subtractions need to be done.

What is the equation of the line that passes through the point (7,−3) and has an undefined slope
Answer:
The equation of the line that passes through the point (7,−3) and has an undefined slope will have the equation: x = 7.
Step-by-step explanation:
As the line has an undefined slope, meaning the line is vertical.
As we know that the vertical line passes through (7, -3), so it can never pass through any x-value other than x = 7, although it can pass through infinite y-values.
so the equation of line will be: x = 7
Therefore, the equation of the line that passes through the point (7,−3) and has an undefined slope will have the equation: x = 7.
