It is a random sample of the green balls in a bag because it never states that he is doing it someone.
<span>The question is asking us to "find the missing number ___:7 = 12:21
First, let's see how similar are 7 and 21 - 21 is 7 multiplied by 3. So the gap will be filled in by something that multiplied by 3 will give us 12. So we have : x*3=12, and also: x=12/4=4, so the answer is
C.4</span>
Answer:
1) y = 30x (same thing as y = 30x + 0)
2) y = 24x (same thing as y = 24x + 0)
3) 270
4) 216
Step-by-step explanation:
Hope this helps :)
-3 • (5x + 2y = 7)
-15x - 6y = -21
-2x + 6y = 9
__________
-17x = -12
x = 12/17
5(12/17) + 2y = 7
2y = 7 - 60/17
2y = 3.47
y = 1.735
