Answer:
-24.
Step-by-step explanation:
0.8*-23+0.8*-7
Use order of operation. Here we have 2 multiplications and one addition The multiplications are done first:
0.8*-23 + 0.8*-7
= -18.4 + -5.6
= -18.4 - 5.6
= -24.
It'd be 0.033 with 3 going till infinity
213_5 = 2*5^2 + 1*5 + 3 = 58 base 10
1111_5 = 5^3 + 5^2 + 5 + 1 = 156 base 10
