Answer:
6=y
Step-by-step explanation:
5y + 6 = -3y +54
isolate y
+3y
8y +6 =54
subtract 6 to isolate y.
8y = 48
divide by 8 so y is alone w no coefficient other than 1
y=6
Substitution method is one of the ways to solve this system.
-5x+y=4 and 4x-4y=16.
First we will divide the second equation with number 4 and get
x-y=4 => x=y+4 than we will replace x in the first equation
-5(y+4)+y=4 => -5y-20+y=4 => -4y=4+20 => -4y=24 => y=-6
x-(-6))=4 => x+6=4 => x=4-6=-2 (x,y)=(-2,-6)
Good luck!!!
add Them all together and divide by the largest

Answer: 125 inches
Step-by-step explanation:
8 3/4 x 2 6/7 = 25
25 x 5 = 125
Answer:
none of the above
Step-by-step explanation:
All of the answer choices agree that the magnitude of the components is 150/√2 ≈ 106.1. The units of these components should be "mph", the same as the units of the magnitude of the given vector.
We only know the angle with respect to horizontal. We don't know whether that angle is measured with respect to the positive x-axis or the negative x-axis. Both of those are horizontal, and there is nothing in the problem statement that restricts the airplane to be traveling in one direction or the other.
Possible answers are ...
<106.1 mph, -106.1 mph> . . . . . . "horizontal" is +x direction
<-106.1 mph, -106.1 mph> . . . . . "horizontal" is -x direction
(The units are not degrees (°).)
