D. Plug in the options to both equations and find which makes both true.
Answer:
3=1/5x+7
Step-by-step explanation:
when it says "Of a number" it means to add a variable, so i added a x. and when it says "more than" it means to add, so 3=1/5x+7 is the answer
I would think you would have to walk the 4 spaces out on the X axis. I would then turn and walk 5 spaces on the Z axis before turning up to walk the last 3 steps on the Y axis.
I think any other way would cause you to move in a negative direction. I hope this helps.
Let’s say the unknown number is x.
therefore,
(2x)^2/3 - 30= 18
4x^2/3 -30 = 18
4x^2-90/ 3 = 18
multiply 18 by 3, and 4x^2-90 by 1
hence,
4x^2-90 = 54
4x^2=144
x^2= 144/4
x^2= 36
x=+ or - 6
hope it helps:)
