x=2 and y = 6 for your awnser hope it helped
X = 2y + 7 ...............(1)
2x + 2y = 200 ........(2)
Substituting the expression for x in equation (1) into equation (2) gives
2(2y + 7) + 2y = 200 .....(3)
Equation (3) simplifies to
6y = 186
Therefore y = 31 feet.
Substituting the value for y into (1) gives
x = 69 feet.
Answer:
y = 1.5
Step-by-step explanation:
Given x is inversely proportional to 
, then the equation relating them is
y = 
← k is the constant of proportion
To find k use the condition when x = 8, y = 2
2 = 
= 
= 
( multiply both sides by 3 )
6 = k
y = 
← equation of proportion
When x = 15 , then
y = 
= 
= 
= 
= 1.5
Answer:
x = -3/4
Step-by-step explanation:
<u>Step 1: Identify the equation</u>
8x + 3 = 4x
<u>Step 2: Move x's to one side and number to the other side</u>
8x + 3 - 4x - 3 = 4x - 4x - 3
4x = -3
<u>Step 3: Make x by itself</u>
4x / 4 = -3 / 4
x = -3/4
Answer: x = -3/4
