Answer:
x = 3
Step-by-step explanation:
6x - 7 = 11
First, add 7 to 11 which gets you 6x = 18
Then, divide 18 by 6 to solve for x which gets you 3
This means that x = 3
(hope this helps)
Answer:
Step-by-step explanation:
6x-7+11
(add 7 to both sides, canceling out the negative 7 on the left, and resulting in a sum of 18 on the right)
6x=18
(divide both sides by 6, which should isolate x because the sixes will cancel each other out, and give you a quotient of 3 on the right side)
x=3

You are making a blueprint of your bedroom and you plan to use a scale factor of 1/8. The actual width of your room is 12 feet and the actual length of your room is 10 feet. Determine the width and length of your room on the blueprint.
Answer:
The width will be 1.5 feet and the length will be 1.25 feet.
Step-by-step explanation:
12/8=1.5
10/8=1.25
Find the equation of the line that contains the point (-5,-3) and is parallel to the line 5x+6y=11. Write the equation in slope-intercept form,if possible.
Answer:
y = -5x/6 - 33/6
Step-by-step explanation:
The standard form of equation of a line in point slope form is y - y0 = m(x - x0)
m is the slope
(x0, y0) is the point on the line
First we need the slope of the given equation 5x+6y=11.
Rewrite in standard form;
5x+6y=11
6y = -5x + 11
y = -5/6 x + 11/6
Hence the slope is -5/6
Since the unknown line is parallel to this line, they will have the same slope, hence the slope of the required line is -5/6
Substitute m = -5/6 and the point (-5,-3) into the point-slope expression;
y - y0 = m(x - x0)
y - (-3) = -5/6 (x - (-5))
y + 3 = -5/6(x+3)
6(y+3) = -5(x+3)
6y+18 = -5x - 15
6y+5x =-15 -18
6y+5x =-33
Express in slope intercept form
6y = -5x - 33
y = -5x/6 - 33/6
In circle M, diameters JL and HK each measure 16 centimeters. What is the approximate length of minor arc JH? Round to the nearest tenth of a centimeter. 3.5 cm 6.9 cm 21.6 cm 46.8 cm
Answer:
3.5 cm
Step-by-step explanation:
The computation of the approximate length of minor arc JH is as follows
As in the attached picture we can see that circle M is shown also the minor arc measures 25 degrees
Now the circle length is
= π × 16
= 50.26 cm.
Now this length would be proportional to 360 degrees
Let us assume the minor length arc JH be x
So, the equation would be
50.26 cm ÷ x cm = 360° ÷ 25°
x = 50.26 × 25 ÷ 360
x = 3.5 cm
Answer:
A. 3.5 cm
Step-by-step explanation:
In the picture attached, circle M is shown.
From the picture, minor arc JH measures 25°.
The length of the circle is π*Diameter = π*16 = 50.26 cm. This length is proportional to 360°. To find the length of minor arc JH, we have to use the next proportion:
50.26 cm / x cm = 360° / 25°
x = 50.26*25/360
x = 3.5 cm

look at the cups shown below (images are not drawn to scale). how many more cubic inches of juice will cup B hold than cup A when both are completely full? round your answer to the nearest tenth.
Answer:
18.8 cubic inches
Step-by-step explanation:
✔️Amount of juice Cup B will hold than Cup A = Volume of cup B - volume of cup A
✔️Volume of Cup B = Volume of cylinder = πr²h
radius (r) = ½ of 2 = 1 in.
height (h) = 7 in.
Volume of cup B = π*1²*7 = 21.99 in.³
✔️Volume of Cup A = Volume of cone = ⅓πr²h
radius (r) = ½ of 2 = 1 in.
height (h) = 3 in.
Volume of cup B = ⅓*π*1²*3 = 3.14 in.³
✔️Amount of juice Cup B will hold than Cup A = 21.99 in.³ - 3.14 in.³ = 18.8 in.³ (nearest tenth)
Answer:
18.8 cubic inches

Answer:
B. y=7x+3
Step-by-step explanation:
You find the changes of y over the changes of x. y sub 2 - y sub 1 divided by x sub 2 over x sub 1. So, 17 - 10 over 2 - 1 = 7. 3 is the y-intercept. y=7x+3

Answer:
[tex]f[2-f^{-1}(x)]=x[/tex]
Step-by-step explanation:
Given function is,
f(x) = [tex]\frac{x-1}{2}[/tex]
Equation form of the function will be,
y = [tex]\frac{x-1}{2}[/tex]
Interchange x and y,
[tex]x=\frac{y-1}{2}[/tex]
Solve for y,
y = 2x + 1
Therefore, inverse of the function 'f' will be,
[tex]f^{-1}(x)=2x+1[/tex]
Now [tex][2-f^{-1}(x)][/tex] = 2 - [2x + 1]
= -2x + 1
Value of [tex]f[2-f^{-1}(x)][/tex] = f(2x + 1)
From the given function,
f(2x + 1) = [tex]\frac{(2x+1)-1}{2}[/tex]
= x
Therefore, value of [tex]f[2-f^{-1}(x)]=x[/tex]

Jerry is paid twice a month. Last month, his first paycheck was for $52. He paid $18 for gasoline and $20 for food. His next paycheck was for $65. He paid $16 for gasoline and $25 for food. What is his balance?
Answer:
Jerry's current balance is $41.
Step-by-step explanation:
We need to subtract what he spent, and add what he gained.
So:
(Money spent)
$18 + $20 = $38
(Current balance)
$52 - $30 = $22
(Current balance)
$65 + $22 = $87
$25 + $16 = $41
Current balance: $41

Can someone explain this problem to me?? After a price reduction of x%, an item has its price increased to its original value. What was the percent of increase? Express your answer as a common fraction in terms of x.
Answer:
[tex]\frac{-100(100+x)}{(x-100)}[/tex]
Step-by-step explanation:
Let the original price of the item = p
Let there was q% of increase on the original value, so
the printed price of the item, [tex]C= p+p \frac{q}{100}=p(1+\frac{q}{100})[/tex]
After a price reduction of x%, the has its price increased to its original value, so,
[tex]C-C\times \frac {x}{100} =[/tex] original price + increased price
[tex]p(1+\frac{q}{100})-p(1+\frac{q}{100})\times \frac {x}{100} = p+p[/tex]
[tex](1+\frac{q}{100})-(1+\frac{q}{100})\times \frac{x}{100} =2[/tex]
[tex]-(1+\frac{q}{100})\times \frac{x}{100} =2-1-\frac{q}{100}[/tex]
[tex]-(1+\frac{q}{100})\times \frac{x}{100} =1-\frac{q}{100}[/tex]
[tex](1+\frac{q}{100})\times \frac{x}{100} =\frac{q}{100}-1[/tex]
[tex]\frac{x}{100}+\frac{q}{100}\times\frac{x}{100}-\frac{q}{100}=-1[/tex]
[tex]x+x \times \frac{q}{100}-q=-100[/tex]
[tex]q(\frac{x}{100}-1)=-100-x[/tex]
[tex]q=\frac{-100(100+x)}{(x-100)}[/tex]
Hence, the percent of the increase is [tex]\frac{-100(100+x)}{(x-100)}[/tex]
