From the given times in Riyadh and Manila, it may be concluded that time is Riyadh is 5 hours earlier than in Manila. When you land on Manila by 2:00 am on Monday, the time in Riyadh was just 9:00 pm on Sunday. Since the total time the travel took is 11 hours and 40 minutes, the time in Riyadh when you left is
9:20 a.m Sunday
Thus, the answer is letter B.
The easiest way to remember this is to do pmbas .
P stands for parenthesis
M stands for multiplication
D stands for division
A stands for addition
S stands for subtraction
you start at parenthesis then you look for division or multiplication after you solve those you do either addition or subtraction finally you find your answer
Answer:
x=9 and y=3
Step-by-step explanation:
Let's solve your system by substitution.
−4x+6y=−18 and y=−2x+21
Rewrite equations:
y=−2x+21;−4x+6y=−18
Step: Solve y=−2x+21for y:
y=−2x+21
Step: Substitute−2x+21foryin−4x+6y=−18:
−4x+6y=−18
−4x+6(−2x+21)=−18
−16x+126=−18(Simplify both sides of the equation)
−16x+126+−126=−18+−126(Add -126 to both sides)
−16x=−144
−16x
−16
=
−144
−16
(Divide both sides by -16)
x=9
Step: Substitute9forxiny=−2x+21:
y=−2x+21
y=(−2)(9)+21
y=3(Simplify both sides of the equation)
Answer:
x=9 and y=3
Answer:
value of x is 4
Step-by-step explanation:
12x-3=17+7x
