Here is a linear equation in two variables: 2x + 4y - 31 = 123.
Solve the equation, first for x and then for y.
Answers
Answer:
x = -2y+77
y = -x/2+77/2
Step-by-step explanation:
The equation for x variable is x = 77 - 2y and for y variable it is; y = 77- x/2
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
WE have been given linear equation in two variables: 2x + 4y - 31 = 123.
Solve for x and for y
2x + 4y - 31 = 123.
Add 31 to both sides
2x + 4y - 31 + 31 = 123 + 31
2x + 4y = 154
Solving for x then Subtract 4y from both sides
2x + 4y -4y = 154 - 4y
2x = 154 - 4y
Divide by 2
x = 77 - 2y
y = 77- x/2

The equation 4 (x - 2) = 100 is a true equation for a particular value of x. Explain why 2 (x - 2) = 50 is also true for the same value of x.
Answers
Answer:
Step-by-step explanation:
i. 4 (x - 2) = 100
x-2= 100/4
x-2=25
x=25+2
x=27
ii. 2 (x - 2) = 50
x-2= 50/2
x-2=25
x=25+2
x=27
The equation 4 (x - 2) = 100 is a true equation for x when x = 27
4 (x - 2) = 100
4x - 8 = 100
Collect like terms
4x = 100 - 8
4x = 92
Divide both side by 4
4x/4 = 92/4
x= 27
Also the equation 4 (x - 2) = 100 is the same as 2 (x - 2) = 50 when the former equation is being divided by 2.
Therefore, the equation 4 (x - 2) = 100 is a true equation for x when x = 27

Answers
Answer:
1 gallon is the better deal
Step-by-step explanation:
If you divide 3.99/4 you get 0.9975. Therefore, a quart of apple juice costs 0.9975. If you divide 3.59/3, you get 1.19 which is more expensive than 0.9975. The answer is 1 gallon of apple juice for 3.99 is the better deal.

A tree is casting a shadow of 28 ft. At the same time, a 7ft statue was casting a shadow of 2ft. How tall is the tree? Remember, I don't want the answer just an explanation
(●'◡'●)
Answers
Answer:
Step-by-step explanation:
You have to find ratio for feet for a shadow.
In your case, a 7ft statue was casting a shadow of 2ft. You divide 7/2 and it results in 3.5 feet in real life vs. 1 foot shadow. You do the same for the tree. Since it is 3.5 feet:1 foot statue, you have to multiply 3.5 by 28 to get the full height of the tree. (In this example the shadow is smaller than the tree that's why you multiply).
