Answer:
460 minutes, or 7 hours and 20 minutes.
Step-by-step explanation:
Your formula is 0.14x+23=0.19x
X represents your minutes.
0.14*460+23=87.4
0.19*460=87.4
I’m pretty sure an equivalent expression would be 2x + 4y
Answer: 90 degrees
============================
Explanation:
Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.
Consequently, we can replace y with x and solve for x like so:
x+y = 180
x+x = 180 .... y is replaced with x since y = x
2x = 180
2x/2 = 180/2
x = 90
This means y = 90 as well. As a check, note how
x+y = 90+90 = 180
which verifies our answer.
.93 * 24 = 22.32
