Answer: choice B) 2 by 6</h3>
===============================================
How I got that answer:
Opposite sides of the rectangle are the same length, so
y = 2x-4 (horizontal sides)
3y = x+3 (vertical sides)
-----------
Start with the second equation. Replace the 'y' with (2x-4) which is from the first equation. This replacement will allow us to solve for y
3y = x+3
3(2x-4) = x+3 .. replaced y with (2x-4)
6x-12 = x+3 ... distribute
6x-12+12 = x+3+12 ..... add 12 to both sides
6x = x+15
6x-x = x+15-x ..... subtract x from both sides
5x = 15
5x/5 = 15/5 ........ divide both sides by 5
x = 3
----------
Now we know the value of x, which means we can find the value of y
y = 2x-4
y = 2*3-4 .... replace x with 3
y = 6-4
y = 2
So the horizontal side is 2 units long
The vertical side is therefore 3y = 3*2 = 6
or we can say x+3 = 3+3 = 6 getting the same answer
Answer:
-1/3x+3 = x-1
Step-by-step explanation:
The solution is (3,-2)
Check and see if the point solves the equation
-1/3x+3 = x-1
-1/3(3) +3 = 3-1
-1+3 = 3-1
2=2 yes
Answer:
There's multiple answers
Step-by-step explanation:
The value of a mixed fraction can be found multiple ways. it can be found on a pie chart, a decimal, or a smaller fraction. perhaps a mixed number.
To write a number into the scientific notation, we need to move the decimal point of the number to the right if the decimal point is before the value or left up if the point is after the the last number of the value. We need to count how many places we moved the point. Then, we write the value after moving and multiply this by 10 to the power of the number you moved the decimal point. If you moved it to the right, then the power would be a negative value. If moved to the left, then the power is positive. We do as follows:
.10316455696
1.0316455696 x 10^-1 = 1.03 x10^-1
