Answer: 11
Step-by-step explanation: if x is equal to 3 then you do 4 times 3 which is 12 then because y is equal to 1 you do 12 minus 1 which is 11
I don’t really know what it is but you can cross out A, B, and F for sure.
New York Boat
Distance = 3470 miles
rate = x + 5
time = 50 hours
London Boat
Distance = 3470 miles
rate = x
time = 50 hours
50(x + 5) + 50x = 3470
Take it from here.
Answer:
216 yds
Step-by-step explanation:
Solve either equation for either variable. Since the second one has y on its own, the easiest choice is to solve that for y.
-5x + y = 13 ⇒ y = 5x + 13
Now substitute this into the other equation to eliminate y and rewrite it entirely in terms of x :
-3x + 3y = 3 ⇒ -3x + 3 (5x + 13) = 3
Simplify and solve for x :
-3x + 15x + 39 = 3
12x = -36
x = -3
Substitute this into either original equation to solve for y. Plugging x = -3 into the first equation would give
-3 (-3) + 3y = 3
9 + 3y = 3
3y = -6
y = -2
So the solution to the system of equations is (x, y) = (-3, -2).
