Answer:

16 in first and 8 in second

Step-by-step explanation:

Let the number of apples be x in the first box then the number in the second box will be 24-x

if we half the number of apples in first box we get  \frac{x}{2}

And we add 4 apples in the second box we get 24-x+4=28-x

Since the apples in the two boxes were 20  we get

\frac{x}{2}+28-x=20

x+56-2x=40

After simplification we get:

x=16

Hence, number of apples in first box were x that is 16

And number of apples in second box were 24-x that is 24-16 is 8

Is 16to 14 and 64to60 equivalent
stiks02 [169]
NO. They are not.

We can prove this by turning those numbers into fractions:

16 / 14 = 1.1428  ;  64 / 60 = 1.0667

Or simply:

64 / 16 = 4
60 / 14 = 4.29

To get the equivalent of 16 to 14; we must multiply both numbers by 4.

16 * 4 = 64
14 * 4 = 56

The equivalent of 16 to 14 is 64 to 56.

2x+y=4                  4x+2y=8

2x     =/2                     2y= /2

y=2                          4x=4

Differentiate the following function.<br> y=x(x^2+5)^2
dalvyx [7]
First, expand to make it easier
y=x(x^2+5)(x^2+5)
y=x(x^4+10x^2+25)
y=x^5+10x^3+25x
differentiation
y'=5x^4+30x^2+25 is the derivitive

Answer:

The hypotenuse is square root of 65

Step-by-step explanation:

a^2 + b^2 = c^2

legs of the right triangle are a and b. Just substitute 4 for a and 7 for b and solve.

4^2+7^2=16+49=65

c^2=65

Find the square root of both sides to get

c=the square root of 65
