Answer:
Step-by-step explanation:
5x + 8y = 24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation.
5x + 8y + -8y = 24 + -8y
Combine like terms: 8y + -8y = 0
5x + 0 = 24 + -8y
5x = 24 + -8y
Divide each side by '5'.
x = 4.8 + -1.6y
Simplifying
x = 4.8 + -1.6y
Answer:
$0.80/oz
Step-by-step explanation:
$4 for 5 ounces
unit cost = price/weight = $4/(5 oz.) = $0.80/oz
Answer:
Ok, I have 2 answers
1. Use Desmos to solve for them or
2. For one of them the y-intercept is 4 so you begin the line at 4 and you go up 2 over 1. For the second -3.5 is the y-intercept so start at -3.5 and go down 1 over 1.
Answer:
The value of x is 5.
The value of y is 4.
Step-by-step explanation:
From the figure, the lengths of the lines with equal number of markings are equal.
So, we will have the length of 7x - 4 = 31.
We solve for 'x'.
We get: 7x = 35
⇒ x = 5
Similarly, 4y + 8 = 24
⇒ 4y = 24 - 8
⇒ 4y = 16
⇒ y = 4
Therefore, the value of x = 5 and y = 4.
Hence, the answer.
-/7? imagine that there is an -1 as the numerator. so now -/7 turns into -1/7
