Answer:

Any c answer that fits 5 <c<37 is correct.

Step-by-step explanation:

Say the three sides of the triangle are  

a

,

b

and  

c

. Here,  

a

=

16

and  

b

=

21

. We must find the possible values of  

c

.

Since  

a

+

c

>

b

, we can input:

16

+

c

>

21

c

>

5

.

So the lower bound of  

c

is everything above  

5

.

We also know that  

a

+

b

>

c

. Inputting:

16

+

21

>

c

37

>

c

.

So  

c

must be less than, but not including  

37

.

In conclusion, the side length  

c

must satisfy the following inequality:

2.<br> - 4x + 9y = 14<br> 12x – 10y = -8<br> ;<br> multiplication
NeTakaya

Answer:

Step-by-step explanation: (Equation 2) = 12(-12+9y/4) - 10y = -8

-144+108y/4 - 10y = -8

-144 + 108y - 40y/4 = -8

-144 + 108y - 40y = -32

108y - 40y = -32+144

68y = 112

Y= 1.64

2-4x+9y=14

12x-10y= -8

2-14+9y = 4x

-12 + 9y = 4x ( equation 3)

(Put in equation 2)

The average of three numbers is 45. two of the numbers are equal. the last number is 89. what are the two missing numbers?
trasher [3.6K]
The average of a set of data is equal to the sum of the values divided by the number of data present. So, if we have three numbers, the average would be:

let x, y and z represent the three numbers
average = x + y + z / 3 = 45

Two number are equal in value, so let x = y. Substituting the value to the expression of average,

45 = x + x + z / 3
45 = 2x + z / 3

It said that the last number is 89 so z is equal to 89.

45 = 2x + 89 / 3
135 = 2x + 89
46 = 2x
x = 23

Therefore, the two numbers are both 23.
