Helppppp which one is it?

If Abigail reads 180 words per minute, and she reads 30 minutes per day, we need to multiply 180 by 30 to figure out how many words she reads per day.

180 × 30 = 5,400

Abigail reads 5,400 words per day.

Then, we divide 32,400 by 5,400 to figure out how many days it would take Abigail to read 32,400 words.

32,400 ÷ 5,400 = 6

It would take Abigail six days to read 32,400 days.

Hope that helped!

Anne and Willow are reading the copy of the same magazine for an assignment.

Kamila [148]

Answer:

Page number 74

Step-by-step explanation:

Let

x ---> the number of days

y ---> the number of pages read

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

The slope is equal to

$m=20\ \frac{pages}{day}$

The y-intercept is equal to

$b=14\ pages$

substitute

$y=20x+14$ ----> equation A

<em>Willow</em>

The slope is equal to

$m=22\ \frac{pages}{day}$

The y-intercept is equal to

$b=8\ pages$

substitute

$y=22x+8$ ----> equation B

equate equation A and equation B

$22x+8=20x+14$

solve for x

$22x-20x=14-8\\2x=6\\x=3\ days$

Find the value of y

substitute the value of x in equation A or equation B

equation A

$y=20(3)+14=74\ pages$

equation B

$y=22(3)+8=74\ pages$

Caps hock Guess and Check (or use Algebra) to solve #3 & # 4 3. Plato has 36 coins in nickels, dimes, and quarters. The numb

Sedaia [141]

Answer:

Part 1:

Let the nickels be = n

Let the dimes be = d

Let the quarters be = q

Plato has 36 coins in nickels, dimes, and quarters. So, equation forms:

$n+d+q=36$ .....(1)

The number of nickels is three less than twice the number of dimes.

$n=2d-3$ ....(2)

The total value of the coins is $5.20.

$0.10d+0.05n+0.25q=5.20$ .... (3)

Substituting n=2d-3 in (1) and (3)

$2d-3+d+q=36$

=> $3d+q=39$ ....(4)

$0.10d+0.05(2d-3)+0.25q=5.20$

=> $0.10d+0.10d-0.15+0.25q=5.20$

=> $0.20d+0.25q=5.35$ ...(5)

Multiplying (4) by 0.25 and subtracting (5) from (4)

$0.75d+0.25q=9.75$ now subtracting (5) from this we get;

$0.55d=4.4$

=> d = 8

Substituting d = 8 in $3d+q=39$

$3(8)+q=39$

$24+q=39$

=> q = 15

Substituting values of d and q in $n+d+q=36$ , we get n

$n+8+15=36$

$n=36-23$

=> n = 13

Therefore Plato has 13 nickels, 15 quarters and 8 dimes.

Part 2:

Let the original price of the ski hat be = x

Original price was marked down by 35% means value was lowered by 35%.

So, we can calculate as:

$x-\frac{35x}{100}=15.60$

=> $\frac{65x}{100}=15.60$

=> $65x=1560$

x = 24

Hence, the original price was $24 but after 35% marking down, it was available for $15.60.
