3.9 can be rounded to 4.
5.3 can be rounded to 5.
4 x 5 = 20
That tells you that 3.9 x 5.3 has a digit in the tens place.
Then you can proceed to multiply 39 and 53, which equals 2067.
(Note: I removed the decimals on purpose)
Now we know that in 2067, the 2 should be in the tens place. That means 0 is in the ones place and that 6 is in the tenths place. That leaves 7 to be in the hundreths place.
Therefore, 3.9 x 5.3 = 20.67
You would add up the ones taking math, science, and both. Then subtract that from 147. Then divide that by 147, then times by 100. This wouldn't work because 95 + 73 = 168.
There you go. I explained in the picture hope it helps
Answer:
m = 1 (since the gradient of parallel lines is the same)
Then substitute point (-1;2)
C = 3
y = x+3
Since the line 3y = 2x+6 can be simplified to
y = 2/3 x + 2, this would lead it to have a y of 6 when it has an x of 6
Using this, it's possible to subtract 6 from the y value to get to 0, and subtract another 4 to get to -4 (while x is six)
In the equation, this would mean just subtracting:
y = 2/3 x - 4 (after subtracting six from other)
- 4
Equation and answer:
y = 2/3 x - 8
To check : Substitute x with 6;
2/3(6) - 8
4 - 8
-4
When X is 6, Y is -4;
