Answer:
B. -1
Step-by-step explanation:
STEP 1: Simplify 3x+2(x−9).
STEP 2: Add 8x and x.
STEP 3: Move all terms containing x to the left side of the equation.
STEP 3: Move all terms not containing x to the right side of the equation.
STEP 4: Divide each term by −4 and simplify.
Hey there!
To start, first let's assign a variable to each person:
A to represent the miles biked by Albert
B to represent the miles biked by Bob
Now, let's set up a system of equations:
A=3B
A + B = 72
Next, use substitution (plug 3B in for A in the second equation since A is equal to 3B):
3B + B = 72
Then, simplify and solve:
3B + B = 72
(combine like terms)
4B = 72
(divide both sides by 4)
B=18
Now that you know the amount that Bob biked, you can plug his miles into the equation for Albert: A=3B
B=18
A=3(18)
A= 54
Your final answer would be that Albert biked 54 miles.
Hope this helps!

Answer:
Algebraically, f is even if and only if f(-x) = f(x) for all x in the domain of f. A function f is odd if the graph of f is symmetric with respect to the origin. Algebraically, f is odd if and only if f(-x) = -f(x) for all x in the domain of f brainliest ?
(x•19)4=752
x would be multiplied by 19 then after it’s getting multiplied by 4.
