Answer:
25
Step-by-step explanation:
The value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286
Rational numbers are numbers written as the ratio of two integers. For example, the fraction 2/7 given is a rational number.
Expressing 2/7 as a decimal number will give;
2/7 = 0.2857142... (It gave repeated decimal values)
Truncating the repeating decimal to the nearest thousandth means writing the decimal to 3 decimal places
0.2857142 = 0.286 (to the nearest thousandth)
Hence the value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286

If you distribute -4 through (5k-7), it equals -20k + 28. Then put on the other -2k on that side of the equals sign and you should have -22k + 28 = -2(9k+5) Then you need to distribute -2 through (9k+5) which equals -18k - 10. You then should have -22k+28=-18k-10. Add 22k to both sides to cancel it out, then you should have 28=4k-10. Add 10 to both sides to get the 4k by itself, which will be 38=4k, then divide both sides by 4 to get k by itself. 38/4 = 19/2. k = 19/2

Answer:
Step-by-step explanation:
y = 3x + 4
Plugin x = 3 in the equation,
y = 3*3 + 4
= 9 + 4
y = 13
Plugin x = 4 in equation,
y = 3*4 + 4
= 12 + 4
y = 16
Plugin x = 5 in the equation,
y = 3*5 + 4
= 15 + 4
y = 19
2) y =x - 7
Plugin x = 10 in the equation
y = 10 - 7
y = 3
Plugin x = 15 in the equation
y = 15 - 7
y = 8
Plugin x = 20 in the equation
y = 20 - 7
y = 13
