hallie has 10 times as many pages to read for her homework assignment as janet, altogether , they have to read 264 pages. how many pages does each girl have to read

Answers

Answer 1

Answer: they read all together you divide then the quotient you divide it by 10 that's how u get ur answer13.2

Answer 2

Answer: Let $j$ be the number of pages Janet has to read.
so Hallie has $10j$ pages to read.
Altogether, they must read $10j + j$ pages, which is $11j$ . So this means that $11j$ must be equal to $264$ .
If you divide both bits by $11$ , you get $j = (264)/(11) = 24$ .
So, Janet has to read $j$ pages, which is $24$ , and Hallie has to read $10j$ pages, which is $240$ .

Ari had 3/4 bag of popcorn his friends ate 1/2 of his popcorn what fraction of the whole bag of popcorn did Ari's friends eat?

Answers

It helps to find a common denominator. 8 would be a good one for this problem. You just change the form of each fraction and subtract.

6/8 - 4/8 = 2/8

His friend ate 2/8 (or 1/4) of his popcorn.

6/8-4/8=2/8 and simlify 1/4.I hope this answer helps:))))))

How do you find the perimeter of a rectangle

Answers

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

Answer:

By adding up all the sides.

Step-by-step explanation:

An example of this is if you had a rectangle with the sides of 2, 5, 2, and 5 you would add all of those numbers up 2 + 5 + 2 + 5 = 14. The perimeter of the rectangle would be 14.

−7x+2y=5
3x−5y=−5

Answers

The solution for given equations $-7x+2y=5$ and $3x-5y=-5$ are x = -0.517 and y = 0.6896.

Step-by-step explanation:

The given is,

$-7x+2y=5$ ..........................(1)

$3x-5y=-5$ ........................(2)

Step:1

Equation (1) is multiplied by 5 ( Eqn(1) × 5)

$-35x+10y=25$ .........................(3)

Equation (2) is multiplied by -2 ( Eqn (2) × -2 )

$-6x+10y=10$ .........................(4)

Step:2

Subtract the equation (3) and (4),

$-35x+10y=25$

$-6x+10y=10$

( - )

$(-35x+6x)+(10y-10y)=(25-10)$

$-29x=15$

$x = - (15)/(29)$

x = -0.517

From the x value equation (2) becomes,

$3(-0.517)-5y=-5$

$-1.551-5y=-5$

$-5y = (-5+1.551)$

$-5y= -3.449$

$y =(3.449)/(5)$

y = 0.6898

Step:3

Check for solution,

$-7x+2y=5$ ..........................(1)

$(-7)(-0.517)+(2)(0.6898)=5$

$3.619+1.3796=5$

5 = 5

Result:

The solution for given equations $-7x+2y=5$ and $3x-5y=-5$ are x= -0.517 and y = 0.6896.

a machine uses 2.5 liters of fuel each hour it runs,its fuel tank was filled with 10 L but 1.5 L have already been used how

many more hours will the machine run

Answers

The number of hours machine runs with 8.5 L fuel is 3.4 hours.

Given that, a machine uses 2.5 liters of fuel each hour it runs, its fuel tank was filled with 10 L but 1.5 L have already been used.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now, 10 - 1.5 = 8.5 L

So, the number of hours = 8.5/2.5

= 3.4 hours

Therefore, the number of hours machine runs with 8.5 L fuel is 3.4 hours.
