Answer:
x = 2/5, y= -22/5
Step-by-step explanation:
4x−y=6;3x−2y=10
Step: Solve4x−y=6for y:
4x−y+−4x=6+−4x(Add -4x to both sides)
−y=−4x+6
-y/-1 = -4x +6 over -1 (Divide both sides by -1)
y=4x−6
Step: Substitute4x−6for y in 3x−2y=10:
3x−2y=10
3x−2(4x−6)=10
−5x+12=10(Simplify both sides of the equation)
−5x+12+−12=10+−12(Add -12 to both sides)
−5x=−2
-5x/-5 = -2/5 (Divide both sides by -5)
x= 2
/5
Step: Substitute 2/
5 for x in y=4x−6:
y=4x−6
y=4 (
2/
5
) −6
y= −22
/5
(Simplify both sides of the equation)
x = 2/5, y= -22/5
When converting decimals to a percentage, simply move the decimal point 2 places to the right
example: .45 to percent
move decimal(or dot) to the right 2 times and you get....
45%
I hope this helps!
Lets do this.
so when you decompose 740 you first get
700
and then you get
40
so your numbers are
700 and 40
or
7 hundreds, 4 tens
Yess it is !!!
You are correct!!
Option A: is the area of the rectangle
Explanation:
Given that the length of the rectangle is
The width of the rectangle is
<u>Area of the rectangle:</u>
The area of the rectangle can be determined using the formula,
Substituting the values of length and width, we get,
Multiplying each term within the parenthesis, we get,
Adding the like terms, we get,
Thus, the area of the rectangle is
Hence, Option A is the correct answer.
