Y = 3/4x - 5/2....subtract 3/4x from both sides
-3/4x + y = -5/2 ....multiply everything by common denominator of 4
-3x + 4y = -10
So we start off by subtracting 137.3 from 180 getting 42.5. If you add the ratios up (3+4) you get 7 and 7 should equal 42.5. thus,
42.5/7= 85/14
(85/14)*3=18.2 or (255/14 to be exact)
(85/14)*4= 24.29 or (170/7 to be exact)
You need PEMDAS
do 3·6 and then 12/6
when you subtract the product and quoetient you get 16 for the answer
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
