Answer:
x = 12
Step-by-step explanation:
Given: the overall angle m∠ADC = (16x − 55) and m∠ADB = 5x - 13.
To solve for x , you can make another equation where
90° (right angle) + m∠ADB = m∠ADC; substitute with terms given
90 + (5x - 13) = (16x - 55); remove parenthesis and combine numbers
5x + 77 = 16x - 55; subtract 5x from both sides
77 = 11x - 55; add 55 to both sides
11x = 132; divide by 11
x = 12
4^3
you can write it like 4 × 4 × 4
you can also call it "Four to the Third power".
Answer:50 cents
Step-by-step explanation:
1 dollar for 2 cans so 50 cents for 1
To find f(4) (i.e. f(x) for x=4), replace all x's with 4 and simplify.
f(x)=1/3x
f(4)=1/3*4
f(4)=4/3=1 1/3=1.333...
