1. y + 5 = ??

2. z - 2x = ??

3. 2z - 2y = ??

4. 2.6y - 2x =??

5. 4(y - x) = ??

6. 4(2 + z) + 5 = ??

Answer 1

1. 11

2. 20

3. 34

4. 12.6

5. 18

6. 105

Explanation:

We are told that ---> t = 0, x = 1.5, y = 6, and z = 23

1. y + 5

= 6 + 5

= 11

2. z - 2x

= 23 - 2(1.5)

= 23 - 3

= 20

3. 2z - 2y

= 2(23) - 2(6)

= 46 - 12

= 34

4. 2.6y - 2x

= 2.6(6) - 2(1.5)

= 15.6 - 3

= 12.6

5. 4(y - x)

= 4(6 - 1.5)

= 24 - 6

= 18

6. 4(2 + z) + 5

= 4(2 + 23) + 5

= 8 + 92 + 5

= 105
