Daniel [21]

Amy: (3 pages/min)(x min) + 9 pages
Sam: (2 pages/min)(x min) + 47 pages

Equate these: 3x+9 = 2x + 47

Then x = 38. The two friends will have covered the same number of pages after 38 minutes. How many pages would that be? 3(38)+9 = 123 pages.

Helppppppppppppppp pleaseeeeee!

stepan [7]

Answer and Explanation:

You got the first one right!

2. You do the same as you did for the first one: to combine the exponents, you multiple 2 by 9 = 18, and now 18 is your new exponent.

$3^{2*9} = 3^{18}$ , which is the answer

3. Here, you can split up the inside so that you have:

$2^5*(y^2)^5= 32*y^{2*5}=32y^{10}$ , which is the answer

Hope this helps! Please give me brainliest if possible.

There are some hens and some sheeps are in a farm,total number of animals are 10 and total number of their legs are 32 1.Find nu

Serhud [2]

Answer: The number of hens are 4 and number of sheeps are 6

Step-by-step explanation:

Given : Total animals = 10

Total number of legs = 32

Let number of hens = h and number of sheep = s

Thus h+s = 10 (1)

Now each hen has two legs and each sheep has 4 legs : $2\times h+4\times s=32$ (2)

Solving for h and s we get:

s = 6 , h =4

Thus number of hens are 4 and number of sheeps are 6
