Answer:
9a+76
Step-by-step explanation:
4 + 9 (a+8)
Distribute the 9 to (a+8)
4 + 9a + 72
Combine like terms
76 +9a
No more like terms, so 9a+76 is your answer
Ryan: y=10x+25 Alex: y=11x+20
a) Mr. Smith should choose Alex because the price would be $42 compared to Ryan which would be $45
b) Mr.Smith could choose either Ryan or Alex because they would both charge $75
So think of |x+6| as a single object. Move the -6|x+6| to the left side and move the 8 to the right side to get 11|x+6| = 0. Then divide both sides by 11 to get |x+6| = 0 and in this instance the || can be dropped because +0 and -0 are the same. so x + 6 = 0 or x=-6
Answer:
angle 1 = angle 2
Step-by-step explanation:
1 and 2 are corresponding angles meaning if they are equal but on opposite sides. If you now for example angle 1 = 20 , 2= is also 20. This is helpful to know if you want to solve for x on one of these angles
Answer:
Let's define:
A = distance traveled before deploying the landing gear
B = distance traveled after deploying the landing gear.
We must have that the sum of those two distances must be equal to 600 yards.
A + B = 600 yd.
And we know that:
" the plane will travel half the distance with the landing gear than without the landing gear."
Then we have that:
B = A/2.
Now we can replace this last equation in the first one:
A + B = 600yd
A + A/2 = 600yd.
(3/2)*A = 600yd.
A = (2/3)*600yd = 400yd.
Ohama should deploy the landing gear 400 yd into the runway.
