Hey there!
d/2 = 2/8
FIRST: you have to CROSS MULTIPLY both of your given numbers
d(8) = 2(2)
d(8) = 8d
2(2) = 4
NEW EQUATION: 8d = 4
SECOND: DIVIDE 8 to BOTH SIDES
8d/8 = 4/8
CANCEL out: 8/8 because that gives you 1
KEEP: 4/8 because it helps you solve for you d-value
NEW EQUATION: d = 4/8
4/8 = d
4/8 = 1/2 = 0.5
Therefore, your answer is: d = 1/2 OR d = 0.5
(NOTE: any of those could work as your “answer” because they are both EQUIVALENT (equal to) to each other)
Good luck on your assignment and enjoy your day!

Answer:
x = 6
Step-by-step explanation:
Here it's sayin that Q is a point in between the end-points P & R. If we join P & R , it forms a line segment & Q is in the line segment PR. Hence PQ & QR are also line segments which combine to form line segment PR. So ,
PR = PQ + QR
Putting the given values of PQ ,QR & PR
=> 4x - 12 + 2x + 7 = 31
=> 6x - 5 = 31
=> 6x = 31 + 5
= 36
=> x = 36/6 = 6
Answer:
Step-by-step explanation:
Point-slope equation for line of slope m that passes through (x₀,y₀):
y-y₀ = m(x-x₀)
In your case, m=5 and (x₀,y₀)=(1,9):
y-9 = 5(x-1)
Answer:
1500 = original price
Step-by-step explanation:
New price of computer = original price - original price * percent off
Factoring out the original price
New price of computer = original price (1- percent off)
We know the new price = 1200 and the percent off =20
Substituting these value in
1200 = original price (1-.2)
1200 = original price (.8)
Divide each side by .8
1200/.8 = original price*.8/.8
1500 = original price
- 4x + 5y = 24; y = 7x + 11y = 7x + 11
= -2,3
