We have
1G = 12.05 - 3D;
Then,
2D + 3( 12.05 - 3D) = 15.50;
2D + 36.15 - 9D = 15.50;
- 7D = - 20.65;
D = 2.95;
Finally, G = 12.05 - 3 x 2.95;
G = 3.20;
Since 3 squared is 9 and 4 squared is 16, the square root of 13 will fall somewhere between 3 and 4
Answer:
75
Step-by-step explanation:
Scores for his first tests were 65, 67, 69.
Rate of change: +2
y=2x+63; 63 is the 0th test he took, his first test was 65, so 65-2=63. 2x is the rate of change, his tests scores increase by 2 each time.
x=6, 6th test score
y=2(6)+63
y=12+63
y=75
So, on his 6th test he will get a score of 75
