Easy 7th grade math for free points 1. Solve for x: 4x+2=18

2. what is 32+4x if x=9

3. what is 3+(5x6)-2x= if x=8

4. What is 9x2+(4x5)x= if x=2

5. Solve for x: 9x9-(9+4)=

6. Solve for x: 9+4x=17

1. 4x + 2 = 18

4x = 18 - 2

4x = 16

x = 4

2. 32+4x if x = 9

32 + 4×9 = 32 + 34 = 70

3. 3+(5×6)-2x= if x=8

3+ 30 - 16 = 33-16= 17

4. 9×2+(4×5)x = if x=2

9×2+(4×5)×2 = 18+20×2 = 18+40=58

5. 9×9-(9+4)= 81 - 13 = 68

6. 9+4x=17

4x = 17-9

4x = 8

x = 2

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
