solve 3-(3x-4)=2x+3(3x-7)
pls help and show steps will mark brainliest
Answer: x=2
Step-by-step explanation:Step 1: Simplify both sides of the equation.
3−(3x−4)=2x+3(3x−7)
3+−1(3x−4)=2x+3(3x−7)(Distribute the Negative Sign)
3+−1(3x)+(−1)(−4)=2x+3(3x−7)
3+−3x+4=2x+3(3x−7)
3+−3x+4=2x+(3)(3x)+(3)(−7)(Distribute)
3+−3x+4=2x+9x+−21
(−3x)+(3+4)=(2x+9x)+(−21)(Combine Like Terms)
−3x+7=11x+−21
−3x+7=11x−21
Step 2: Subtract 11x from both sides.
−3x+7−11x=11x−21−11x
−14x+7=−21
Step 3: Subtract 7 from both sides.
−14x+7−7=−21−7
−14x=−28
Step 4: Divide both sides by -14.
−14x
−14
=
−28
−14
x=2

The length of a rectangular room is 7 feet longer than twice the width. If the room's perimeter is 146 feet what are the room's dimensions?
Width - 22 ft: length - 51 ft
Width - 33 ft: length - 40 ft
Width - 27 ft: length - 61 ft
Width - 44 ft: length - 102 ft
Answer:
width- 22ft : length-51 ft
Step-by-step explanation:
if you add 22+22 its 44 +7 it will give you 51.
that is twice the width+ the 7 feet
The dimensions of the room will be 22 feet and 51 feet. Then the correct option is A.
What is the perimeter of the rectangle?The sum of all the sides of the rectangle will be known as the perimeter of the rectangle. Let L be the length and W be the width of the rectangle.
Then the perimeter of the rectangle will be
Perimeter of the rectangle = 2(L + W) units
The length of a rectangular room is 7 feet longer than twice the width. Then we have
L = 2W + 7
If the room's perimeter is 146 feet. Then the dimension of the rectangle will be
P = 2(L + W)
146 = 2(2W + 7 + W)
73 = 3W + 7
3W = 66
W = 22 feet
Then the length of the rectangle will be
L = 2 x 22 + 7
L = 44 + 7
L = 51 feet
The dimensions of the room will be 22 feet and 51 feet. Then the correct option is A.

This sounds dum but I don't know what the line on top is for. (step-by-step explanation would be appreciated)
Answer:
C: 5/11
Step-by-step explanation:
The top line over the numbers usually mean the numbers are recurring (occurring again and again)
So 0.45 with the dash over the 45 means 0.454545454545... (goes forever, hence why we use the dash)
To solve you convert each option to a decimal and find one that has 0.45 recurring.
A: 4/5 =0.8
B: 5/9 = 0.55...
C: 5/11 = 0.45...
D: 4/9 = 0.44...
Hence, our answer is C.
Answer: It means that the numbers the bar is over repeats. Answer is C
Step-by-step explanation:
For example:
Example 1: [tex]0.123 \overline {4}[/tex] → The bar is only over the number 4 so only the number 4 repeats. [tex]0.123 \overline {4} = 0.123444444444444444444444...[/tex] with the number 4 repeating forever.
Example 2: [tex]0.12 \overline {34}[/tex] → This time the bar is over the 3 and the 4, so 34 and 4 repeat. [tex]0.12 \overline {34} = 0.12343434343434...[/tex]
Example 3: [tex]0.1 \overline {234}[/tex] = 0.1234234234234234234...
Example 4: [tex]0. \overline {1234}[/tex] = 0.123412341234123412341234...\
To solve your problem, it will be easiest to use a calculator and test each answer.
Choice A: [tex]\frac{4}{5} = .8 \neq . \overline{45}[/tex]
Choice B: [tex]\frac{5}{9} = 0.55555556 \neq 0. \overline{45}[/tex]
Choice C: [tex]\frac{5}{11} = 0.454545454545... = 0. \overline {45}[/tex]
Choice D: [tex]\frac{4}{9} = .44444444444... = 0. \overline {4} \neq 0. \overline {45}[/tex]

Given the following least-squares regression line, how many seconds does this model predict a 7-foot pendulum would take to complete one period?
Answer:
the answer is the 1 with the check on it
11.2 seconds given model predicts a 7-foot pendulum that would take to complete one period.
The correct answer is option (D)
What is regression?"It is statistical model which is used to determine the relationship between variables."
What is least square method?"The least squares method is a mathematical regression analysis used to determine the line of best fit for a set of data."
Logarithm property:If log x = b, then x = (10)^b
Given : the least-squares regression line,
log Time = 0.699 + 0.500 log(Length)
We need to find the time when given model predict a 7 foot pendulum would take to complete one period.
Here, Length = 7 ft
Using given model,
⇒ log Time = 0.699 + 0.500 log(7)
⇒ log Time = 0.699 + (0.5 × 0.8451)
⇒log Time = 0.699 + 0.423
⇒ log Time = 1.122
⇒ Time = [tex]10^{1.122}[/tex]
⇒ Time = 13.2 seconds
Therefore, the correct answer is option (D) 13.2 seconds.

Elena wants to make a scale drawing of her bedroom. Her bedroom is a rectangle with length 5 m and width 3 m. She decides on a scale of 1 to 50. Draw and label the dimensions of a scale drawing of Elena's bedroom, using a scale of 1 to 50. Elena's bedroom door is 0.8 m wide. How wide should the door be on the scale drawing? Explain how you know. Elena's bed measures 4 cm by 3 cm on the scale drawing. What are the actual measurements of her bed? How would I draw this out
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Actual length of rectangular bedroom = 5m
Actual width of rectangular bedroom = 3m
Scale = 1 to 50
Scaled length of bedroom = 5m/50 = 0.1m = 0.1 * 100= 10cm
Scaled width of bedroom = 3m/50 = 0.06m = 0.06 * 100= 6cm
If width of door = 0.8m wide
Scaled width of door : 0.8m/50 = 0.016m = 0.016 * 100 = 1.6cm
Bed measures : 4cm by 3cm on scale drawing ;
Actual bed dimension:
4cm * 50 = 200cm ; 200/ 100 = 2m
3cm * 50 = 150cm ; 150 / 100 = 1.5m
Ricky is inviting 8 friends to a party. If each friend will get 6 cookies and in each box are 10 cookies, how many boxes will Ricky need to get?
Answer:
5
Step-by-step explanation:
8 times 6 is 48. 5 boxes times 10 in each one is 50 cookies.
Number of boxes Ricky needs to get to a party is equals to 5 boxes.
What is word problem?
" A word problem is a mathematical problem in which we represents the real life examples with the help of mathematical operation."
According to the question,
Number of friends invited in a party = 8
Number of cookies given to each friend = 6
Total number of cookies required for 8 friends = 8 × 6
= 48 cookies
Number of cookies in each box = 10 cookies
Number of boxes for 1 cookie = 1 / 10
Number of boxes for 48 cookies = (1 / 10) × 48
= 4.8
= 5 boxes (Number of boxes cannot be
in decimals)
Hence, number of boxes Ricky needs to get to a party is equals to 5 boxes.

write an equation of the quadratic function that has x-intercepts 5-i√2 and 5+i√2
Answer:
f(x) = x² - 10x + 27
Step-by-step explanation:
Given the x- intercepts of f(x) are x = a and x = b, then the factors are
(x - a) and (x - b) and f(x) is the product of the factors, that is
f(x) = (x - a)(x - b)
Here the x- intercepts are 5 - i[tex]\sqrt{2}[/tex] and 5 + i[tex]\sqrt{2}[/tex] , thus the factors are
(x - (5 - i[tex]\sqrt{2}[/tex] )) and (x - (5 + i[tex]\sqrt{2}[/tex] )) , that is
(x - 5 + i[tex]\sqrt{2}[/tex]) and (x - 5 - i[tex]\sqrt{2}[/tex] , then
f(x) = (x - 5 + i[tex]\sqrt{2}[/tex] )(x - 5 - i[tex]\sqrt{2}[/tex] ) ← expand using FOIL
= (x - 5)² - 2i² ← i² = - 1
= x² - 10x + 25 + 2

A metal worker has 57 grams of an alloy that is 37% gold. She also has a large supply of an alloy that is 17% gold. How many grams of the 17% gold alloy does she need to add to the 37% gold alloy to obtain an alloy that is 25% gold? Write your answer as a whole number or as a decimal rounded to the nearest tenth.
Answer:
85.5 grams of 17% gold alloy is added.
Step-by-step explanation:
A metal worker has 57 grams of an alloy that is 37% gold.
And let x grams of an alloy which is 17% gold.
Let's add them to get 25% of (x+57)grams of alloy.
So, we can set up equation as
57(37%) +x(17%) =(x+57)(25%)
Simplify and solve the equation for x.
21.09+0.17 x= 0.25 x+14.25
Subtract both sides 0.25 x
21.09-0.08 x =14.25
Subtract both sides 19.95
-0.08 x=-6.84
Divide both sides by -0.08
x=85.5 grams
