Answer 1

3) a. 16

b. 30

c. 22

4) 1

Explanation:

3) To solve this problem you must substitute the values of a and b into each expression, as you can see below:

a.
`a+2b=2+(2*7)=16`

b.
`6(b-a)=6(7-2)=6(5)=30`

c.
`3(a+b)-5=3(2+7)-5=3(9)-5=27-5=22`

4) To solve this exercise you must substitute the values of x, y and z into the given expression, as following:

`xz+y=(3*0)+1=0+1=1`
