How can we use variables and equations to help us
solve problems?
Answer:
Variables help show the numbers and equation show the numbers
Step-by-step explanation:
Answer:
If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

What is the equation of the line that passes through the point (5,6) and has a slope of 2?
PLZ HELP AND EXPLAIN HOW YOU SOLVE!!! THANK YOU AND HAVE A GREAT DAY!!
Answer:
Answer is at the bottom!!
Step-by-step explanation:
y = - \frac{2}{5} x - 2
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 5y = 10 into this form
subtract 2x from both sides
5y = - 2x + 10 ( divide all terms by 5 )
y = - \frac{2}{5} x + 2 ← point- slope form with slope m = - \frac{2}{5}
Parallel lines have equal slopes hence
y = - \frac{2}{5} x + c is the partial equation of the parallel line
to find c, substitute ( 5, - 4 ) into the partial equation
- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2
y = - \frac{2}{5} x - 2 ← equation of parallel line
Hope this helps!!

9. Three minutes after a hot tub starts to fill, the tub contains 24
gallons of water. After 5 minutes the tub contains 40 gallons of water.
The relationship between the number the number of gallons in the hot
tub and the time in minutes is a proportional linear relationship.
Determine the number of gallons of water the tub increases per minute.
Answer:
8 gallons per minute
Step-by-step explanation:
24 gallons in 3 minutes
you divide 24 by 3 which is 8
40 gallons in 5 minutes
you divide 40 by 5 which is 8
the relationship is that in both the answer was 8 as in 8 gallons per minute

Joe goes to the store to buy milk that cost x + $3, bread that cost x + $2.25, and 3 bags of potato chips that cost x + $1.50 each. Write an equivalent expression to represent what he spent.
Given:
Milk cost = x + $3,
Bread cost = x + $2.25,
3 bags of potato chips cost = x + $1.50 each.
To find:
The equivalent expression to represent what he spent.
Solution:
1 bag of potato chips cost = x + $1.50
3 bag of potato chips cost = 3(x + $1.50).
Total cost = Milk cost + Bread cost + Cost of 3 bags of potato chips
[tex]\text{Total cost}=(x+\$3)+(x+\$2.25)+3(x+\$1.50)[/tex]
[tex]\text{Total cost}=x+\$3+x+\$2.25+3x+\$4.50[/tex]
[tex]\text{Total cost}=(x+x+3x)+\$(3+2.25+4.50)[/tex]
[tex]\text{Total cost}=5x+\$9.75[/tex]
Therefore, the required expression is 5x+$9.75.

Given: 4d=1/3(c-d) Proof= c=13d
Proof:
Multiply both of the sides by 3. You would get 12d = c - d. Add d on both sides, and you would get c = 12d
Here, we are required to proof c = 13d from 4d=1/3(c-d)
Ultimately, c = 13d (proof)
We have;
4d=1/3(c-d)Cross product
4d × 3 = c - d
therefore, By collecting like terms;
C = 12d +d
and Ultimately, c = 13d ......

A cement path consists of six equal-sized cement squares arranged in a row to form a rectangle. If the total area of the path is 96 square feet, what is the length in feet of the path?
Answer:
24 feet
Step-by-step explanation:
Given that:
The length of the rectangle is 6 times the side of a cement square.
Now, this rectangle is formed from 6 squares;
The total area of the path of this square = 96 square feet;
The area of each square now = 96/6 = 16 square feet
Recall that:
Area of a square = S²
where S is the side length
16 = S²
S = [tex]\sqrt{16}[/tex]
S = 4 ft
The length of the path in feet now is: L × w
= 6 × 4
= 24 feet.
