Answer:
D. 2x²
Step-by-step explanation:
Ok, so the first thing to do is remember the first number in parentheses is x, and the second number is y.
You're trying to figure out which expression turns x into y in each set.
Just by plugging in the numbers into each expression I found that the answer is 2x².
I'll prove this starting with (1, 2).
1² = 1
2 x 1 = 2
So, y = 2x²!
Next, (2, 8).
2² = 4
2 x 4 = 8
So, y = 2x²!
I'm not going to demonstrate with the other two but I hope you understand. Just plug the values of x and y into the equation and see which is correct.
Would it be 33/10? If you are multiplying and then division you would use the inverse of the divided fraction and multiply. So you could invert 2/5 to 5/2 and add to 4/5. After finding the common denominator it would be adding 8/10 + 25/10 = 33/10.
Answer:
30 3
Step-by-step explanation:
30 is 27 numbers more than 3
4x and 2x line along a straight line, their sum then must be 180° so
6x=180
x=30
So the angles in there are:
3(30)-5=85°
2(30)=60°
4(30)=120°
If Nick began with three clients, you would do basic math to get here.
January / 3
February / 3•2 = 6
March / 6•2 = 12
April / 12•2 = 24
May / 24•2 = 48
June / 48•2 = 96
July / 96•2 = 192
August / 192•2 = 384
September / 384•2 = 768
October / 768•2 = 1,536
November / 1,536•2 = 3,072
December / 3,072•2 = 6,144
Nick would start with 3 clients and end with 6,144 clients.
