Answer:

x = 13

Step-by-step explanation:

There are two ways to do this. You could use the Pythagorean Theorem because you are given that the triangles are right angled triangles.

Method One

a^2 + b^2 = c^2

a = 5

b = 12

c = ?

c^2 = 5^2 + 12^2

c^2 = 25 + 144

c^2 = 169

sqrt(c^2) = sqrt(169)

c = 13

x = 13

Method Two

You can do this problem with similar triangles.

48/12 = 52/x                    Cross multiply

48x = 12 * 52                   Combine the right  

48x = 624                        Divide by 48

48x/48 = 624/48              Do the division

x = 13

using the numbers 3, 5, and 8, can you write nine proper fractions and nine improper fractions? You may use each number only onc
Bond [772]

Answer:

First, we can write a fraction as a/b

Where a is the numerator, and b is the denominator.

A proper fraction is a fraction where the numerator is smaller than the denominator.

Using only the given numbers (only once per fraction), some examples of proper fractions are:

3/5

3/8

5/8

3/85

3/58

5/83

5/38

8/35

8/53

You can see that in all of them the denominator is larger than the numerator.

The improper fractions are those where the numerator is equal or larger than the denominator.

The 9 examples using the given numbers are:

5/3

8/5

8/3

35/8

38/5

53/8

58/3

83/5

85/3

Can someone plz help? Only have a hour...I'll make crown the best and triple the points!!!
kykrilka [37]

Answer:

x= 3.57

Step-by-step explanation:

32 ( x + 2.5) = 114.24

32* x + 32* 2.5= 114.24

32x + 80= 114.24

        -80      -80

32x= 114.24

/ 32    /32

x= 3.57

for the part that says convince me, we can use the eqution

/= divide
