x = 3 + y Eqn(1)
y = -2x + 9 Eqn(2)
Let us solve the system of equations with the substitution method
x - 3 = y (Subtracting 3 from both sides of the Eqn(1))
Replacing y = x - 3 in Eqn (2), we have:
x - 3 = -2x + 9
x = -2x + 9 + 3 (Adding 3 to both sides of the equation)
x + 2x = 9 + 3 (Adding 2x to both sides of the equation)
3x = 12 ( Adding like terms)
x = 12/3 (Dividing by 3 on both sides of the equation)
x = 4
Replacing x=4 in Eqn(1), we have:
4 = 3 + y
4 - 3 = y (Subtracting 3 from both sides of the equation)
y=1
The answers are:
x= 4 and y=1
Answer: 10 over 69 or 10/69
Step-by-step explanation: convert the expression 5 divided by 34.5 then convert the decimal into a fraction 5÷ 69/2. To divide by a fraction, multiply by the reciprocal of the fraction 5× 2/69. By calculating the product you end up with 10/69
Assuming the 100 people sampled are representative of the population as a whole, the answer is choice B. Most people who own a cat would dislike dogs according to the survey. We can only talk about cat owners since the 100 people selected are cat owners. We can't say anything about pet owners in general.
Hi there!
First of all simplify x+5(x-1)=(x-3)4-1.
This would make 6x-5=4x-13.
Next, subtract 4x from both sides.
6x-5-4x=4x-13-4x
2x-5=-13
Then add 5 to both sides.
2x-5+5=-13+5
2x=-8
Finally divide by 2 on both sides.
2x/2=-8/2
x=-4
Your answer is -4.
Hope this helped!
