Evaluate each expression for the given values of the variable: 8z + 3;z = 8

67

Step-by-step explanation:

8z + 3

Let z =8

8*8+3

64+3

67

67

Step-by-step explanation:

This question is based on substitution in which a specific number will be given to replace a letter, hope you understand

Then back to the question

8z+3 and z is given to be 8

Let's substitute

8(8)+3

64+3

67

Therefore the final answer is 67

I believe you understand how we get this final answer

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
