Answer:
-16
Step-by-step explanation:
Represent the number by n.
Then:
8(n + 18) = 16
Performing the indicated multiplication, we get:
8n + 144 = 16
Subtracting 144 from both sides results in 8n = -128.
Dividing both sides by 8: n = -128/8 = -16
The number was -16.
Answer:
either 81 or 81.8
Step-by-step explanation:
Answer:
2/9
Step-by-step explanation:
Total outcome = 36
Sum of 7 = 6
Prob of sum of 7 = 6/36
Sum of 11 = 2
Prob of sum of 11 = 2/36
Prob of sum of 7 or 11 = 6/36+2/36
Prob of sum of 7 or 11 = (6+2)/36
Prob of sum of 7 or 11 = 8/36 = 2/9
Surface area of a cuboid
= [2(length)(width)] + [2(width)(height)] + [2(height)(length)]
= {[2(4)(2.5)] + [2(2.5)(2)] + [2(2)(4)]} units²
= (20 + 10 + 16) units²
= 46 units²
