Answer:
x³+3
Step-by-step explanation:
Answer: x=18
im assuming that this is a right angle
so if it is then that means the total of the angle should be 90 degrees. so 2x+3x should be equal to 90. Just combine like terms to get that 5x=90 and then isolate the variable (divide by 5 on both sides) so x ends up equaling 18.
so x=18
Answer:
Step-by-step explanation:
We have the equation of the position of the object
We need to solve the equation for the variable a
Subtract 
and 
on both sides of the equality
multiply by 2 on both sides of equality
Divide between 
on both sides of the equation
Finally
Answer:
There are 12 sections, out of the 12 sections the third section is marked. So that would be, 3/12 which simplifies to 1/4
To solve this problem, first let x=0.933333(repeating). Then, you want to multiply both sides by 10 to get 10x = 9.33333 (repeating). Next, take equation 2 and minus equation 1 from it giving you 9x = 8.4. Finally, multiply both sides by 10 and you will get 90x = 84. Divide both sides by 90 giving x=84/90. Answer is 84/90. 84/90 can reduce to 14/15.
