See the photo attached below, answer is D
Answer:
x = 3
y = 8
Step-by-step explanation:
ok we will substitute
y = x + 5
into the second equation
4x + y = 20
4x + (x + 5) = 20
5x + 5 = 20
5x = 15
x = 3
y = x + 5 = 3 + 5 = 8
The value of x is 1
Explanation:
The equation is 
Subtracting both sides by 3, we get,

Taking log on both sides, we get,

Rewriting the equation by 
Thus, we have,

Applying log rule, if
, then 
Thus, 
Substituting
in
, we get,

Also, since,
, then 
Thus, 
Hence, the value of x is 1

While multiplying decimals by 10, 100, 1,000 and so on, just move the decimal to the right by how many zeros you have in the number. Let’s say I have 7.9 x 10. Move the decimal one place to the right because you have ONE zero. Then your answer would be 79.
