1a 2a
Step-by-step explanation:
n × (−2+5 ) = −8+20
n × 3 = 12
n = 4
2 + (n+6) = −1+6
n + 8 = 5
n = -3
Answer:
686 becomes 700
Step-by-step explanation:
367+319 = 686
hundreds tens one
6 8 6
We are rounding to the hundreds places
We have to look at the tens place
8>=5 so we will round up
6 becomes 7
686 becomes 700
3 + (2 + 8)^2 / 4 * (1/2)^4
3 + 10^2 / 4 * (1/2)^4
3 + 100/4 * (1/2)^4
3 + 25 * 1/16
3 + 25/16
48/16 + 25/16
73/16
4 9/16 <==
