2x - 10 = 10 - 3x
Simplifying
2x + -10 = 10 + -3x
Reorder the terms:
-10 + 2x = 10 + -3x
Solving
-10 + 2x = 10 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
-10 + 2x + 3x = 10 + -3x + 3x
Combine like terms: 2x + 3x = 5x
-10 + 5x = 10 + -3x + 3x
Combine like terms: -3x + 3x = 0
-10 + 5x = 10 + 0
-10 + 5x = 10
Add '10' to each side of the equation.
-10 + 10 + 5x = 10 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 10 + 10
5x = 10 + 10
Combine like terms: 10 + 10 = 20
5x = 20
Divide each side by '5'.
x = 4
Simplifying
x = 4
(350-126)/(5-3)=112m/s
This is the average speed in the time from 3 to 5 seconds...
dd/dt 98,126,154
d2d/dt2 28,28
She actually had a constant acceleration over the entire time period.
The function for that table is:
d(t)=14t^2
Her actual velocity at any point is v(t)=28t (you can see that if you take the mid point of the interval, 4s, you will get the average velocity found earlier)
<span>−<span>1/<span><span>(<span>y+1</span>)</span><span>(<span>y<span>−1</span></span>) is the answer</span></span></span></span>
Answer: The value of x is 22
5x-5=6x-27
5x-6x=-27+5
-x=-22
x=22
Brainliest pwease if I give you the correct answer!~ <3
One meter would equal 2.23694 miles per hour.
