A. 13
Step-by-step explanation:
What we are given....
∠A = 26° + x
∠B = 38° + x
∠A and ∠B are complementary
If complementary angles add up to equal 90° and ∠A and ∠B are complementary to each other
Then 26 + x + 38 + x = 90
^ ( Note that we just created an equation that we can use to solve for x )
Now its just basic algebra
26 + x + 38 + x = 90
step 1 combine like terms
26 + 38 = 64
x + x = 2x
we now have 64 + 2x = 90
step 2 subtract 64 from each side
64 - 64 cancels out
90 - 64 = 26
we now have 26 = 2x
step 3 divide each side by 2
26 / 2 = 13
2x / 2 = x
we're left with x = 13
Y=2/3x-2
the answer to your question is as written above.
Answer:
Washington plane = 500 mph
LA plane = 600 mph
Step-by-step explanation:
Speed of Washington plane(mph) = w
Speed of LA plane(mph) = w + 100
2700 - 2(w + w + 100) = 500
2700 - 2(2w + 100) = 500
2200 - 4w - 200 = 0
4w + 200 = 2200
4w = 2000
w = 500
w + 100 = 600
