Answer:

He bought 544 oranges and 1,360 apples

Step-by-step explanation:

Here, we want to know the number of oranges and apples bought

Let the number of oranges be x and the number of apples be y

Looking at their ratios;

x:y = 2:5

so;

x/y = 2/5

2y = 5x ••••••(i)

Now, he lost 3/4 of the apples ( by giving out)

What would be left with him is (1-3/4) = 1/4 * y = 0.25y

What is left with him out if the oranges will be; x-34

So now;

0.25y/x-34 = 2/3

3(0.25y) = 2(x-34) •••••••(ii)

From i, y = 5x/2 = 2.5x

Putting this into ii above, we have

3(0.25)(2.5x) = 2x - 68

1.875x = 2x-68

2x-1.875x = 68

0.125x = 68

x = 68/0.125

x = 544

But y = 2.5x

y = 2.5 * 544 = 1,360

Small notebooks cost $3.50 and large notebooks cost $5.00. She needs to buy 31 notebooks, and she has $134 to spend. How many sm
Darina [25.2K]

Let's assume

number of small notebooks =x

number of large notebooks =y

we are given

total number of notebooks =31

so, we get

x+y=31

now, we can solve for y

y=31-x

we have

Small notebooks cost $3.50 and large notebooks cost $5.00

she has $134 to spend

so, we get

3.50x+5y=134

now, we can plug y

3.50x+5(31-x)=134

3.50x+5*31-5x=134

-1.5x+155=134

-1.5x+155-155=134-155

x=14

now, we can find y

y=31-14

y=17

so,

number of small notebooks is 14

number of large notebooks is 17.............Answer

Answer:

Step-by-step explanation:

dy/dx = d/dx log root under x-1 / root under x+1

dy/dx = root under x+1 / root under x-1 * 1/(x+1)^2/3 * 1/root under x-1

dy/dx = (x+1)^2/ x-1
