Well, 1/2*7=3.5. So you have to do each equation to see which ones are not equal to 3.5. A) 1*7=7/2=3.5 so A is not the right answer. B) 1/2*7=1/14=.07, so B is one of the correct answers. C) 1*7=7*2=14, so C is another one of the correct answers. D) 1*7/2=7/2=3.5, so D is not a correct answer. E) 14 is not equal to 3.5, so E is another correct answer. So the correct answers are B, C, and E.

Solve the following system by the substitution method.<br>1/4x+2/3y=-17/4<br>3x-y=3
madam [21]
3x - y = 3.....3x - 3 = y

1/4x + 2/3(3x - 3) = -17/4
1/4x + 2x - 2 = -17/4 ...multiply everything by 4
x + 8x - 8 = -17
9x = -17 + 8
9x = - 9
x = -1

3x - y = 3
3(-1) - y = 3
-3 - y = 3
-3 - 3 = y
-6 = y

solution is (-1,-6)

If yo travel56mph how far will you go in2hr15min how long does it take to cover 168 miles
Alex73 [517]
2 hr 15 min = 2 \frac{1}{4} hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 = 126 miles

"how long" means time ... so using the same formula 
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time
