Answer:
[tex]x + \frac{2}{5} \times x = 70 \\ x + \frac{2}{5} x = 70[/tex]
Answer:
Let it be x the number.
We have to sum to x two fifths of him and we know the result is 70, so:
[tex]x + \frac{2}{5}x = 70[/tex]
We could also solve it:
[tex]\frac{5x}{5}+\frac{2x}{5}=\frac{350}{5}[/tex]
[tex]5x + 2x = 350[/tex]
[tex]7x = 350[/tex]
[tex]x=\frac{350}{7}=50[/tex]

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

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.

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

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

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

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.
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.
