Answer:
2x + 15 = 37 - 2
Step-by-step explanation:
we know his age is the variable x
so (Two times his age plus fifteen equals thirty seven minus two) turns into:
2x (plus fifteen equals thirty seven minus two)
plus fifteen is +15 so now we have:
2x + 15 (equals thirty seven minus two)
equals is =, so now we have:
2x + 15 = (thirty seven minus two)
thirty seven is 37, so now we have:
2x + 15 = 37 (minus two)
minus two is -2, so now we have:
2x + 15 = 37 - 2
2+6+8+12+12=40
40 divided by 5=8
6+2+0+4+4=16
16 divided by 5=3.2
MAD=3.2
1,400 is 1,427 rounded to the nearest hundred because everything in front of what you have to round to stays the same and the number next to 4 is a 2 so you let it rest and stay a 4 and everything after that becomes a 0
You are doing an experiment in science and you need to add exactly 250 mL to a beaker. But the markings on the container have rubbed off from so much use. But you have a ruler. By figuring out the volume of the cylinder, you can figure out where the 250 mL line is. :)
Answer:
-4
Step-by-step explanation:
-2i times (-2i) can be rewritten as (-2)^2*i^2.
Recalling that i^2 = -1, we then have (-2)^2*(-1)
Completing this evaluation, we get -4.
