Answer:
Let the number be x.
8 times that number would be 8x, and taking away 18 from it 8x - 18. Knowing the result of doing this is 30, we can write the following equation:
8x - 18 = 30
And solve it. First we pass the -18 to the sight umming:
8x = 30 + 18
8x = 48
Then the 8 which is multiplying to the right dividig:
x = 48/8 = 6
Now we verify we have done it preporly:
8x - 18 = 30
8 * 6 - 18 = 30
48 - 18 = 30 TRUE
Answer:
x =6
Step-by-step explanation:
Translate into algebraic equation =
[tex]8(x)-18= 30\\= 8x-13=30[/tex]
Let's solve for x
[tex]\mathrm{Add\:}18\mathrm{\:to\:both\:sides}\\8x-18+18=30+18[/tex]
Simplify
[tex]8x=48[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}=\frac{48}{8}[/tex]
Simplify
[tex]x =6[/tex]
George is putting trim around his rectangular deck, including the gate. He will need 44 feet of trim to do the entire deck. If the deck is 12 feet long, how wide is the deck?
20 feet
8 feet
22 feet
10 feet
Answer:
10 feet
Step-by-step explanation:
perimeter of the deck=44 feet
P=2 length+ 2 width
44=2(12)+2w
44=24+2w
2w=44-24
w=20/2 ⇒ w=10 feet
check: P=2l+2w ⇒ 2(12)+2(10) ⇒ 24+20=44 feet

Which ratios are equivalent to 10:16? Check all that apply. 30 to 48 25:35 StartFraction 40 Over 64 EndFraction 8:32 5 to 15
Answer:
30 to 48, 40/64
Step-by-step explanation:
Which ratios are equivalent to 10:16, and they gave us 30 to 48, 25:35, 40/64, 8/32 and 5 to 15.
For 30 to 48, we can mulitply the 10:16 by 3 to give us 30:48, so it is equal.
For 25:35, we simplify it to 5:7, while 10:16 is 5:8, so they are not equal.
For 40/64, we can take 10:16 and multiply them by 4, getting the same number. Therefore, it is equal.
For 8/32, we can simplify it down to 1/4, while 10:16 simplifies down to 5:8, it is not equal.
Lastly, for 5 to 15, w can simplify that to 1/3, and get 5:8 for 10:16, so it won't be equal.
Jack read 20 pages of a book in 60 minutes. How many pages can he read in 75 minutes at the same rate? Write a proportional equation. Please help me answer this equation!!
Answer:
25 pages
Step-by-step explanation:
Create a proportion:
[tex]\frac{pages}{minutes}[/tex] = [tex]\frac{20}{60}[/tex] = [tex]\frac{x}{75}[/tex]
Cross multiply and solve for x, the number of pages in 75 minutes:
60x = 1500
x = 25
So, he can read 25 pages in 75 minutes at the same rate
I need help arranging cards in a 4 x 4 grid with numbers 1-9 so that the sum of each row and each column is 20. This what the grid looks like:
Answer:
8, 2, 8, 2
7, 3, 7, 3
6, 4 6, 4
9, 1, 9, 1
Step-by-step explanation:
In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.
So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.
Since there are 18 numbers, I'm assuming we don't have to use all of them.

A sample of 257 adults is selected. The adults are classified according to voter registration status ("registered" or "not registered"). They are also classified according to preferred source of current events information ("television", "newspapers", "radio", or "internet sites"). The results are given in the contingency table below. What is the relative frequency of adults in the sample who are not registered to vote? Round your answer to two decimal places.
The relative frequency of adults in the sample who are not registered to vote is 0.47.
What is the relative frequency?Relative frequency is a statistical concept that refers to the proportion or percentage of observations or events in a given sample or population that fall into a particular category or have a particular characteristic.
We have,
To find the relative frequency of adults in the sample who are not registered to vote, we need to sum up the number of adults who are not registered:
22 + 39 + 21 + 39 = 121 and divide it by the total sample size which is 257.
Relative frequency of adults who are not registered to vote
= (number of adults who are not registered) / (total sample size)
Relative frequency of adults who are not registered to vote.
= 121/257
Relative frequency of adults who are not registered to vote
= 0.47 (rounded to two decimal places)
Therefore,
The relative frequency of adults in the sample who are not registered to vote is 0.47.

What is a pre-image??? SaberXTooth bro answer me!!!
Answer:
Step-by-step explanation:Much is usually anticipated about the fierce and decidedly bloody clashes between Wolverine and Victor Creed, the man known as Sabretooth, even though these men are arguably two sides of the same coin. Each of them has deadly claws that rend and draw blood; each has a generous amount of fear and intimidation working for them; each has a healing factor that prevents them from being mortally wounded (eventually reaching preposterous levels of effectiveness); and each has killed and will kill if the situation calls for it. Yet there are differences, as well: Logan's skeleton, as well as his claws, are made of the unbreakable metal known as adamantium; and while there have often been instances where he's been shown to be merciless, he's not nearly as sadistic as Creed, who will not hesitate to kill even when there is no reason for it. Perhaps the difference that keeps us engaged, however, is the fact

What value of x satisfies the equation?
Answer: The answer is D
Step-by-step explanation: First you distribute the 2 by x and 2 so you get 2x + 4 then you distribute -3 by x and -1 so you get -3x + 3 then you add up the two equations then yo get -x + 7 = 9 then you subtract the 7 on both sides so you get x = -2

Answer:
61
Step-by-step explanation:
13 - 1 = 1212 ÷ 2 = 6Put 6 and 1 together: 61Therefore, the number is 61
Let's check:
6 × 2 = 1212 + 1 = 13The sum of the two digits is 13, and we got that, so we are correct. The number is 61.
Answer:
49
Step-by-step explanation:
let unit digit=x
ten's digit=y
then x+y=13
x=13-y
also x=2y+1
13-y=2y+1
13-1=2y+y
3y=12
y=12/3=4
x=13-4=9
so number =10×4+9=49
if a $1000 investment earns %20 interest compounded annually, then the investment will double in value in how many years?
Answer:
In four years.Step-by-step explanation:
End of first year:
1000 + 20%•1000 = 1000 + 200 = $1200
End of second year:
1200 + 20%•1200 = 1200 + 240 = $1440
End of third year:
1440 + 20%•1440 = 1440 + 288 = $1728
End of fourth year:
1728 + 20%•1728 = 1728 + 345.6 = $2073.6 >2•$1000
surface area of composite figures
Answer:
408 cm²
Step-by-step explanation:
You can find the total area by dividing the figure into two different parts. You have one large rectangle and two smaller triangles that have the same given dimensions, meaning that the triangles will have the same area. Find the area for the divided figures first.
Rectangle
The length is 24 cm (6 + 8 + 10). The width is 15 cm.
A = lw
A = (24 cm)(15 cm)
A = 360 cm²
Triangle
The height is 6 cm. The base is 8 cm.
A = 1/2bh
A = 1/2(6)(8)
A = 3(8)
A = 24 cm²
Now, add the areas together. Since there are two triangles, make sure to account for that in your calculations.
360 cm² + 24 cm² + 24 cm² = 408 cm²
Answer:
408 cm^2
Step-by-step explanation:
You would just find the surface area of all of the shapes and then add them all together so for the 2 triangles you would just multiply 6 and 8 and divide by 2 so you would get 24 for both of then so then you would find the area of all of the rectangles so for the smallest one you would do 15 times 6 which is 90 then you would multiply 15 and 8 for the middle triangle and that would be 120 and for the last rectangle, you would multiply 15 and 10 which is 150 and then you would add all of them up. The numbers would be 24,24,90,120,150 and when you add them up you would get 408 cm^2
