How do i solve 3x/3 = 6/3
Answer: 2=x
Step-by-step explanation: Multiply both sides by three then divide both sides by three.
3x=6
x=2
Answer:
x = 2
Step-by-step explanation:
3x/3 = 6/3
cross-multiply:
9x = 18
divide both sides by nine:
x = 2
On a bicycle, you can travel 20 miles in 4 hours. At this
same rate, what distance can you travel in 6 hours?
Answer:
30miles
Step-by-step explanation:
You go 5 miles everyone 1 hour (you can find this out by dividing 20 by 4)
5 multiplied by 6 equals 30
20÷4=55×6=30
Write the equation of a line through the point (7,-10) and
perpendicular to 5y + 3x = 15.
Step-by-step explanation:
In order to find the equation I used the following formula:

The parallelogram pictured below has a perimeter of 129. Find the value of y.
Answer:
y = 2½ = 2.5
Step-by-step explanation:
From the question given above, the following data were obtained:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
The perimeter of a parallelogram can be obtained by using the following formula:
Perimeter = 2(a + b)
Thus, with the above formula, we can obtain the value of y as shown below:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
Perimeter = 2(a + b)
Perimeter = 2a + 2b
129 = 2(10y – 9) + 2(17y + 6)
Clear bracket
129 = 20y – 18 + 34y + 12
Collect like terms
129 + 18 – 12 = 20y + 34y
135 = 54y
Divide both side by the coefficient of y i.e 54
y = 135/54
y = 2½ = 2.5
Thus, the value of y is 2½ or 2.5
At which point does the graph of the equation 2x+y=4 cross the x-axis
Answer: It crosses the x-axis at 2
Step-by-step explanation:
Hope this helped!
Answer:
easy, x=2 or (2,0)
Step-by-step explanation:
Since you are solving for x, you need to make y 0. So 2x+y(0)=4, 2x+0=4, 2x=4,x=2. So there you have it. x=2 or (2,0)
3(2a+5b)+5(a-2b)
Who can tell me the answer for this one please
Answer:
11a + 5b
Step-by-step explanation:
3(2a + 5b) + 5(a-2b)
First, distribute 3 to 2a and 5b, and distribute 5 to a and -2b
6a + 15b + 5a - 10b
Combine like terms
11a + 5b
Have a good day, be safe

What is
-3/4 + 2 3/4
Answer:
2
Step-by-step explanation:
ok so let's start
were starting off with -3/4 and were adding 2 3/4 to that and it's equal to 2 3/4 subtract 3/4
-3/4 + 2 3/4 = 2 3/4 - 3/4
2 3/4 - 3/4 = 2
-3/4 + 2 3/4 = 2

Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
When you combine like terms you see the ones that are similar then you add or subtract, depends on what the signs are. For this one -7x is similar to x so in this case you would add x to the -7x which will give you -6x.

Error Analysis: Isabel says that the equation x-2=-(x-2) has no solution because a number can never be equal to its opposite. Explain the error Isabel made. "MP.3"
Look for Relationship: You are solving an equation with a variable on each side. Does the side on which you choose to isolate the variable affect the solution? Why might you choose one side over the other? "MP.7"
Answer:
Zero is a number that can be equal to its opposite.
So, the given equation has solution for which LHS=RHS=0.
Step-by-step explanation:
The answer to the equation is 2

John bought 3 pants for 25 dollars each and paid with a one hundred-dollar bill. Write a numerical expression to represent this situation and then find how much money John gets back from the cashier?
What is the slope of the two points (-2,7) and (4,-8)
Answer:
-15/6
Step-by-step explanation:
If you look at the first number in each point, the x coordinate, you see the 2nd point is 6 forward from the 1st point. Now the 2nd number is the y coordinate, and you can see it goes down 15 from the 1st coordinate. So y/x is the slope.
Answer: -2 1/2
Step-by-step explanation:
Slope= Yb-Ya/Xb-Xa
In this case= (-8-7)/(4- -2)
This equals -15/6
Simply to -2 1/2

What is the slope of a line perpendicular to the line whose equation is
12x – 3y = 81. Fully reduce your answer.
Answer:
slope of perpendicular line is -1/4
Step-by-step explanation:
slope of standard equation of line that is ax+ by = c is
slope m = -a/b
given equation is
12x – 3y = 81
comparing it with ax+ by = c
a = 12
b = -3
thus
slope of given line = -12/-3 = 4
we also know product of slope of two perpendicular line is -1
let the slope of other line be m
thus,
product of given line line and perpendicular line is -1
4*m = -1
m = -1/4
Thus,
slope of perpendicular line is -1/4

Answer:

Step-by-step explanation:
Answer:
Step-by-step explanation:
First you have to figure out n. Let's say it's 1, then you would multiply it by 4. That would be 4. Then subtract 32. In this case, then the answer would be - 28.
For this one, first you have to figure out w. Let's make w = 2. Then multiply is by 3 so it would be 6. Then add 66. In this case, it would be 72.
I hope this helps!
