What is the value of the expression below when z = 10 and w = 7
10z + 9w

Answers

Answer 1

Answer:

163

Step-by-step explanation:

10(10)+9(7)=

100+63=163

Answer 2

Answer:

163

Step-by-step explanation:

If z=10 and w=7.

10z+9w [writing the equation again for reference purposes]

10(10) + 9(7) [we substitute each variable with its defined value]

100 + 9(7) [we multiply 10 and 10, aka 10 and z]

100 + 63 [we multiple 9 and 7, aka 9 and w]

163 [we add 100 and 63 to get our final answer]
