Question

if k +7=10then find the value 9k-50​

Answer 1

Answer:

Value = -23

Step-by-step explanation:

k= 10-7=3

k=3

= 9(3)-50

= 27-50

= -23

Answer 2

The value of (9k-50) is -23

Given : The given equation is, k+7=10

To find : The value of (9k-50)

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the value of 9k-50)

First of all, we have to calculate the value of k.

So,

k+7 = 10

k = 10-7

k = 3

Now, putting the value of k in the algebraic expression of which we have to calculate the value.

So,

= 9k-50

= (9×3) - 50

= 27 - 50

= -23

(This will be considered as the final result.)

Hence, the value of (9k-50) is -23
