3 scoops of powder lemonade mix are required to make to courts of lemonade have many scoops of powder eliminate mix are required to make 3 gallons of lemonade
Answer:
I guess that the question should say:
You need 3 scoops of powder lemonade mix to make two quarts of lemonade. How many scoops of powder lemonade mix are needed to make 3 gallons?
3 gallons = 12 quarts
if you need 3 scoops top make 2 quarts, then you will need (12/2) x 3 = 18 scoops of lemonade powder mix to make 3 gallons of lemonade.
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.

a rope of length 13 1/2 m has been divided into 9 pieces of the Same length what is the length of each pice
Answer:
When 13 1/2 into proper fraction it will be 27/2=13.5
Then divide 13.5 by 9
It becomes 1.5, so that means the ropes are 1.5 meters each
Step-by-step explanation:
I hope this helps, please give me brainliest
if we divide the 13.5 by 9 we will get the answer 1.5 and so we have 9 pieces of the length 1.5

Find the equation of the line that passes through (4,4) and is parallel to
y=3x+4 Leave your answer in the form y=mx+c
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + y + 2 = 0 ( subtract 3x + 2 from both sides )
y = - 3x - 2 ← in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + c ← is the partial equation
To find c substitute (3, - 4) into the partial equation
- 4 = - 9 + c ⇒ c = - 4 + 9 = 5
y = - 3x + 5 ← equation of line in form y = mx + c
The equation of line which parallel to given line is, [tex]y=3x-8[/tex]
Slope intercept form:The equation of line in slope intercept form is,
[tex]y=mx+c[/tex]
Where m is slope of line and c is y-intercept.
Equation of line given that,
[tex]y=3x+4[/tex]
So that, slope of line is [tex]3[/tex]
We have to find the equation of the line that passes through (4,4) and is parallel to given lines.
Since, slope of all parallel lines are same.
Equation of required line is,
[tex]y=3x+c[/tex]
Substitute point (4,4) in above line.
[tex]4=12+c\\\\c=4-12=-8[/tex]
So that, equation of line become,
[tex]y=3x-8[/tex]

Molly estimated the her car insurance was going to be $250 each month. It was actually going to be $230 each month. What is the percent error? *
Answer:
8.69%.
Step-by-step explanation:
Estimated value = $250
Actual value = $230
We need to find the percent error. It can be calculated as follows :
[tex]\%=\dfrac{|\text{estimated-actual}|}{\text{actual}}\times 100\\\\=\dfrac{250-230}{230}\times 100\\\\=8.69\%[/tex]
So, the percent error is 8.69%.

2(x+7) 2x + 20
- 2 =
x+4
2x + 8
Answer:
x = 0
Step-by-step explanation:
2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing
2(x+7) would be 2x+14
4(2x+8) would be 8x+32
2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms
2x and 2x can be combined on the left side
x and 8x can be combined on the right side
4x + 14 + 20 - 2 = x + 8x + 32
4x + 32 = 9x + 32 you can now solve this equation
start by subtracting 4x on both sides
32 = 5x +32 now subtract 32 on both sides
0 = 5x so x = 0
Answer:
x = 0
2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing
2(x+7) would be 2x+14
4(2x+8) would be 8x+32
2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms
2x and 2x can be combined on the left side
x and 8x can be combined on the right side
4x + 14 + 20 - 2 = x + 8x + 32
4x + 32 = 9x + 32 you can now solve this equation
start by subtracting 4x on both sides
32 = 5x +32 now subtract 32 on both sides
0 = 5x so x = 0

y = -10x + 91
Write an equation in point-slope form for the line with a slope of 1/4 that passes through the point (-1, -8)
Answer:
y = 1/4 x - 31/4
Step-by-step explanation:
Slope (m) = 1/4
Point A (-1, -8)
y = mx + b
-8 = 1/4 (-1) + b
-8 + 1/4 = b
b = -32/4 + 1/4
b = -31/4
y = mx + b <-- this is a linear equation, continuing line, so there are infinite values for x and y. Therefore we don't have to plug the values of x and y in
y = 1/4 x + - 31/4
y = 1/4 x - 31/4

Please help me with this one please, I've been having trouble figuring this one out.
Answer:
y = - 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (2, - 3)
m = [tex]\frac{-3-5}{2+2}[/tex] = [tex]\frac{-8}{4}[/tex] = - 2
The line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 ← equation of line
