52.5 divide by 121 is .43, so that means each person represents .43% of the 7th grade population. so by multiplying 231 by .43 you get 100%. the number of students in 7th grade is 231
A) 2x - 7 = -1
Add 7 to both sides of the equation.
2x = 6
x = 3
Choice A is not the answer.
B) 3x + 8 = 1
Subtract 8 from both sides.
3x = -7
Divide both sides by 3.
x = -2.3 repeating
Choice B is not the answer.
C) 1/2x + 8 = 10
1/2x = 2
Divide both sides by 1/2.
x = 4
Choice C is not the answer.
By process of elimination, choice D is the answer.
D) 1/2(2x - 6) = -6
x - 3 = -6
Add 3 to both sides.
x = -3
40 x 0.35 = 14
40 - 14 = 26
The price is $26.
0=41
