6*(10+25)
60+150
210 is your answer
Answer:
33 and 34
Step-by-step explanation:
Let the integers be x and x+1 respectively.
4x = 3(x+1) + 30
x = 33
therefore, the integers are 33 and 34

Answer:
- 6.045×10^40 ergs
- 1.8×10^-2 mm
Step-by-step explanation:
A) Your scientific or graphing calculator can tell you the product:
(3.9×10^33 erg/s)(1.55×10^7 s) = 6.045×10^40 ergs
__
B) 10^2 mm is 100 mm, about 4 inches, so 1.8×10^2 mm is about 7 inches. This is somewhat larger than the diameter of a human hair (and about the same size as the diameter of a human <em>head</em>).
1.8×10^-2 mm = 18 μm is a more reasonable estimate of hair diameter
(The range of hair diameters is reportedly about 17 to 181 μm, so the given dimension is on the low end.)
Answer: x= -7/5 procedure: -2x-8-1=3x-6+4 -2x-9=3x-2 -2x-3x= -2+9 -5x= 7 answer: x= -7/5
Here is the answer of the given problem above.
In order to get the speed, we need to use the formula s= d/t (Speed = distance over time). Given that the distance is 170 kilometers and the time is 2.5 hours, we divide 170 by 2.5 and we get 68. Therefore, the speed that he traveled is 68km/hr. Hope this answer helps.
