Is the open sentence 3z = 2z +5 true or false when z=5?

1 answer:

8 0

If 3z=2z+5 and z=5, then you’d just plug the 5 in.

3(5)=2(5)+5 —> 15=10+5 —> 15=15

This statement is TRUE because 15 does equal 15.

I hope this helps. :)

The formula that we will use is:
C × {{1 - [1/(1 + r)t]}/r} +c

C = 100,0000
r = .12
t = 20

= 100000 * {{1 - [ 1/ (1 + .12)^19]}/ .12} + 100000
approximately 836,577.69

I am using a scientific calculator so just insert right the number and you will come up with the correct answer. The answer in this question is $836,577.69
