if you divide 7 into 9 you get the decimal of the fraction. so 7 divided by 9 is 0.777777778
<span>The correct answer to this question is 3.0
Explanation:
Since the displacement is defined to be the change in position of an object.
Displacement is a vector. This means it has a direction as well as a magnitude and is represented visually as an arrow that points from the initial position to the final position.
Displacement = âš3^2+(4-4)^2) = 3</span>
Equation: (Not sure if it's the right order...)
468 = 40x + 18(x - 3)
The fee Micheal charges each suscriber is $6
Work:
468 = 40x + 18(x - 3)
468 = 40x + 18x - 54
Mutilpy 18 & x and 18 & 3
468 = 58x - 54
Add 40x amd 18x
468 + 54 = 58x - 54
Add 54 to 468 to have -54 gone in 58x - 54
522 divide by 58 is 9
x = 9
9 - 3 = 6
× = .5 or 1/2 because .5×4=2
Here's how you solve this. So, x+y=2, right? Let's isolate x. x+y-y=2-y. x=2-y. NOW, if x=2-y, in 3x+2y=5, we can REPLACE x with 2-y and use it to solve for y! 3x+2y=5. 3(2-y)+2y=5. (3*2)+(3*-y)+2y=5. 6+(-3y)+2y=5. 6+(-y)=5. 6+(-y)-6=5-6. -y=-1. -y/-1=-1/-1. y=1.
So, if y=1, we can substitute that back into either equation--but let's go with the easier one, x+y=2. x+1=2. x+1-1=2-1. x=1. 1+1=2, so that works; let's check the other equation. 3(1)+2(1)=5. 3+2=5. 5=5. That's correct!
Answer: x=1, y=1
