the answer is
x=8y/3(1-8y)
y=3x/8(1+3x)
hope this helped l used cymath to solve this problem.
good day : )
($3.91)(0.09) = $0.3519
$3.91 + 0.3519 = $4.2619 per gallon
if you're looking for the total expense next year:
($4.2619)(370 gallons) = $1,576.903
Answer:
By plotting in the number in the equation (aka where all the x’s are variables are) and seeing if it works.
Step-by-step explanation:
For example, let’s use the problem:
3x + 4 = 16
if the given number is 4, we fill it in for x-
3 (4) + 4= 16
solve to see if true:
12 + 4 = 16
16 = 16
hence, the given number 4 makes the equation true!
hopes this helps, have a great day :)
Answer:
3x - y = 8
y = 3x - 8
y = 3*2.5 - 8 = -0.5 --> (2.5, -0.5)
y = 3*5 - 8 = 7 --> (5, 7)
Answer C is correct.
Given that GI = 53, and
• GH = 3x - 11
• HI = 2x + 4
We can establish the following equality statement to solve for x:
GH + HI = GI
3x - 11 + 2x + 4 = 53
Combine like terms:
5x - 7 = 53
Add 7 to both sides:
5x - 7 + 7 = 53 + 7
5x = 60
Divide both sides by 5 to solve for x:
5x/5 = 60/5
x = 12
Substitute the value of x into the equality statement to verify if it is the correct value for x:
GH + HI = GI
3x - 11 + 2x + 4 = 53
3(12) - 11 + 2(12) + 4 = 53
36 - 11 + 24 + 4 = 53
53 = 53 (True statement. Thus, x = 12 is the correct value).
Therefore:
GH = 3x - 11
GH = 3(12) - 11
GH = 25
HI = 2x + 4
HI = 2(12) + 4
HI = 28
