Answer:

Step-by-step explanation:

2n - 6

a) n = 1 ;   2n - 6 = 2*1 - 6  = 2 - 6 = -4

  n = 2 ;   2n - 6 = 2*2 - 6 = 4 - 6 = -2

  n = 3 ;   2n - 6 = 2*3 - 6 = 6 - 6 = 0

b) n=10;  2n - 6 = 2*10 - 6 = 20 - 6 = 14

Jane is making a suit which requires 2 5⁄8 yards for the jacket and 1 3⁄4 yards for the skirt. What's the total amount of materi
Ann [662]
The answer is B. 4 3⁄8 yards. The amount of material needed for the jacket is: x = 2 5/8 yd = 2 + 5/8 = 16/8 + 5/8 = (16+5)/8 = 21/8 yd. The amount of material needed for the skirt is: y = 1 3/4 yd = 1 + 3/4 = 4/4 + 3/4 = (4+3)/4 = 7/4 yd. The total amount of material Jane needs is: x + y = 21/8 + 7/4 = 21/8 + 14/8 = (21+14)/8 = 35/8 = (32+3)/8 = 32/8 + 3/8 = 4 + 3/8 = 4 3/8 yd.

Q #7 please solve the equation
pishuonlain [190]
The relation between a and s is given to be:

a = 640s

where,

a = number of acres
s = number of square miles

We are to find the number of acres for 7.5 square miles.

This means, s = 7.5

Using the value in the formula, we get:

a = 640 x 7.5 = 4800 acres

So the answer to this question is option B
