Answer:
69.5 and 70.5
Step-by-step explanation:
consecutive numbers mean they are one up from the other
- e.g. 2 and 3,
- 15 and 16
if the first one is x, we can write the second consecutive number as x + 1
The info tells us the sum of these two numbers is 140, so we can write an equation and solve for x.
x + (x + 1) = 140
2x + 1 = 140
2x = 139
x = 139/2 = 69.5
(now we find the next number)
69.5 + 1 = 70.5
Step-by-step explanation:
a^2 + 8^2 = 10^2
a^2 =10^2 - 8^2
a^2 =100-64
a^2 =36
(square root it)
a =6
200,000 + 10,000 + 8,000 + 300 +70 + 5 = 218,375
