38.9 is the answer. because it is rounded to the nearest tenth.
-3 is an integer and a rational number.
Natural numbers and while numbers refer to positive numbers, so -3 cannot be either of those.
40 mins left! total time= 60 mins x 3 hours =180 mins. 180 divided by 9 is 20. 20 times 7 is 140. 180-140 equals 40. yay!
Answer:
Step-by-step explanation:
2*x + 3 = 1/2x + 30 Subtract 3 from both sides
<u> - 3 -3</u>
2x = 1/2x + 27 Subtract 1/2 x from both sides
<u>1/2 x -1/2 x</u>
1 1/2 x = 27 change 1 1/2 to 3/2
3/2 x = 27 Multiply by 2/3
2/3 * 3/2x = 27 * 2/3
x = 18
The distributive property is...
a(b + c) = ab + ac
or
a(b - c) = ab - ac
So...
root6 (root30 - 2)
= root6 x root30 - root6 x 2
= root180 - 2root6
= 6root5 - 2root6
6root5 means 6 x root5
2root6 means 2 x root6
