Answers
If your solving for R the answer is r= -1/5 -6/5v v€r here’s the solving steps to solve for r 4-5 (1r) -2=3+6 v so when the term has a coefficient of 1 it doesn’t need to be written so 4-5r-2=3+6v then subtract the numbers so 2-5r=3+6v then 5r=3+6v-2 then subtract so then 5r=1+6v then
Henry incorrectly said the rate 1/3 pound / 1/9 gallon can be written as the unit rate 1/27 pound per gallon. What is the correct unit rate? What was Henry´s likely error?
Answers
Answer:
The unit rate is 3 pounds per gallon.
Henry's likely error could have been that he multiplied instead of dividing.
Step-by-step explanation:
Given the rate 1/3 pound / 1/9 gallon, this can be written in the unit rate by dividing 1/3 pound by 1/9 gallon. First, we will evaluate 1/3 divided by 1/9 and the unit will be in pound per gallon.
1/3 divided by 1/9 can be written as
[tex]\frac{1}{3} \div \frac{1}{9}[/tex]
This then becomes
[tex]\frac{1}{3} \times \frac{9}{1}[/tex]
[tex]\frac{1}{3} \times \frac{9}{1} = \frac{9}{3} = 3[/tex]
Hence, the unit rate is 3 pounds per gallon.
Henry's likely error could have been that he multiplied instead of dividing. That is, he multiplied 1/3 by 1/9, Such that he gets
[tex]\frac{1}{3} \times \frac{1}{9}[/tex]
[tex]\frac{1}{3} \times \frac{1}{9} = \frac{1}{27}[/tex]
Hence, the 1/27 pound per gallon he got.

How can you look at the equation of two lines and determine if they will be perpendicular?
Answers
Answer:
By looking at the slope
Step-by-step explanation:
Let's use these equation: y = 2x + 3 and y = 2x - 9
You know that those two equations are parallel because the slope is the exact same!
But, if we rewrite those equations to: y = -2x + 3 and y = 1/2x - 9
You can now see that the equations are perpendicular because the slopes are Opposite Reciprocal. The slopes have opposite signs (pos./neg.) and are reciprocal numbers: 2 = 1/2
Use a translation rule to describe the translation that is 3 units to the right and 6 units down
1. (x, y) --> (x + 3, y + 6)
2. (x, y) --> (x + 3, y - 6)
3. (x, y) --> (x - 3, y - 6)
4. (x, y) --> (x - 3, y + 6)
Answers
Step-by-step explanation:
Translation that is 3 units to the right and 6 units down translate the point (x,y) into the point (x+3,y-6). Example: if you translate the origin (0,0) 6 units to the left and 5 units up, then you obtain point (-6,5)

Alejandra correctly wrote the equation y – 3 = y minus 3 equals StartFraction 1 Over 5 EndFraction left-parenthesis x minus 10 right-parenthesis.(x – 10) to represent a line that her teacher sketched. The teacher then changed the line so it had a slope of 2, but still went through the same point. Which equation should Alejandra write to represent the new line?
Answers
Answer:
The equation Alejandra should write to represent the new line should be
y-3 = 2(x-10)
Step-by-step explanation:
The equation Alejandra wrote for the line her teacher sketched is
y-3 = 1/5 (x-10).
This can be related to the equation of a line in point slope form. The equation of line in point slope form
is
y - y₁ = m (x - x₁)
Where (x₁, y₁) is a point on line
and m is the slope of the line.
Hence, for the equation Alejandra wrote
The line went through point (3,10) and the slope of the line is 1/5.
Now, from the question
The teacher changed the line so it had a slope of 2, but still went through the same point. That is, the line still went through point (3,10).
In the new line the teacher sketched, the values of x₁ and y₁ remain the same but the value of the slope (m) has changed.
The slope of the new line is 2, that is, m =2.
Therefore,
The equation that represents the new line is
y-3 = 2(x-10)
Hence, the equation Alejandra should write to represent the new line should be y-3 = 2(x-10).
Question Category: Writing Linear Functions and Equations

Answer:
1. One solution
2. No solution
Step-by-step explanation:
1.Step 1: Subtract 2x from both sides.
5x+3−2x=2x−3−2x
3x+3=−3
Step 2: Subtract 3 from both sides.
3x+3−3=−3−3
3x=−6
Step 3: Divide both sides by 3.
3x + -6
3 2
x=−2
Answer:
1)One solution
2)No solutions
Step-by-step explanation:
To solve this for the first one you should add both sides by three to get the constants on one side.
5x+3+3=2x
Combine like terms.
5x+6=2x
Get x to one side by subtracting 5x on each side.
6=-3x
Solve for x.
x=6/-3 or x=-2
Which means one solution.
To solve the second one you should o all the steps above, but to find:
8=3
Which is not true, so no solutions.
A boat travled 27 miles in 2 hours. At this rate, how many miles will the boat travel in 1/2 hour ?
Answers
Answer:
54 miles
Step-by-step explanation:
Just divide the 27 miles to the half hour and you will see how many miles the boat travelled. In 27 miles in 2 hours is 13.5 miles so we figured out what we get in two hour so to find out for the half an hour you do the same thing
Answer:
6.75 miles.
Step-by-step explanation:
1/2 is 1/4 of 2 hours, so you'd take 1/4 of 27 (which is 27/4) and you would get 6.75.
If that explanation is a little difficult to understand, let me know and I will rephrase!

D) 5
Answers
Answer:
for the second part its d+2.5d+d-4
Step-by-step explanation:
The part of the expression represents the total amount each friend pays is d+2.5d+d-4.
What is Expression?An expression is combination of variables, numbers and operators.
Each friend pays for the entrance fee, a booklet of ride tickets, and a meal ticket.
The entrance fee costs d dollars.
A booklet of ride tickets costs 2.5 times the entrance fee, which is 2.5d dollars.
A meal ticket costs $4 less than the entrance fee, which is (d - 4) dollars.
Therefore, the total amount each friend pays is:
d + 2.5d + (d - 4)
Simplifying the expression, we get:
4.5d - 4
Hence, d+2.5d+d-4 is the part of the expression represents the total amount each friend pays.
