Answer:

Choice C

Step-by-step explanation:

3 3/4 would be a better benchmark than all other fractions. Although 3.05 would look realistic, it would be unreasonable.

16, 12, 8    17. 14, 11   op = -4,-3

3, 7, 15     24, 16. 12  op 4,4    because difference = op 4, 8 = 4   op -8, -4 = 4

Step-by-step explanation:

9+ 2 = 11, 13,15  ordered pair 2

5+ 3 = 8, 11, 14   ordered pair  3

20-4 = 16, 12, 8  ordered pair -4

20-3 = 17. 14, 11  ordered pair -3

1 x 2 +1  = 3, 7, 15 ordered pair  4, 8 = 4

three times the sum of a number and 4 is 8 less than one-half the number. write and solve an equation to find the answer
garri49 [273]

3(x + 4) = 1/2x - 8

...multiply 3

3x + 12 = 1/2x - 8

...subtract 1/2x

2.5x + 12 = -8

...subtract 12

2.5x = -20

...divide by 2.5

x = -8
