The resulting equation will be x + y = 4 and 4y =20
<h3>System of equation</h3>
GIven the system of equation given as:
x + y = 4
-3x + y = 8
If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:
3x + 3y = 12
-3x + y = 8
Adding both equation
3y + y = 12 + 8
4y = 20
Hence the resulting equation will be x + y = 4 and 4y =20

Answer:
The probability that an item selected for inspection is classified as defective is 0.01485.
Step-by-step explanation:
Denote the events as follows:
A₁ = an item produced by the company is defective.
A₂ = an item produced by the company is not defective.
X = an item is classified as defective by the inspector.
Given:
P (X|A₁) = 0.99
P (X|A₂) = 0.005
P (A₁) = 0.01
P (A₂) = 1 - P (A₁) = 1 - 0.01 = 0.99
The law of total probability states that:
Use this law to compute the probability that an item selected for inspection is classified as defective as follows:
Thus, the probability that an item selected for inspection is classified as defective is 0.01485.
The theater sold a total of 1,026 tickets. You have to find 80% of 600 and 91% of 600. 91% x 600= 546 and 80% x 600= 480. You add the two numbers to get the total.
Answer:The value of w cannot be a negative number, substitution is used to replace the variable L with a value of 20, the subtraction property of equality is used to isolate the term with the variable w.
