Answer:
The measure of the unknown angle is 15°.
Step-by-step explanation:
Represent this angle by A. Then the complement of A is 90° - A.
"Angle whose complement is five times its measure" would be expressed as
90° - A = 5A
Solve this for A by adding A to both sides:
90° = 6A. Then A = 90°/6, or 15°
Answer:
53/5
Step-by-step explanation:
since 10 is the denominator of the denominator we can move it to the numerator, giving us 10n/5-3n = 1/5
multiply all sides by 5-3n, giving us 10n = (5-3n)/5
now multiply by 5 to get rid of the final denomintor, 50n = 5-3n
move 3n to the other side 53n = 5, n = 53/5
Answer:
Step-by-step explanation:
(3x – 5)(–x + 4)
(3x)(–x) + (3x)(4) + (–5)(–x) + (–5)(4).
-3x^2+12x +5x -20
-3x^2+ 17x -20
Answer:
Step-by-step explanation:
cuz 7 is greater then 5
Answer:
I have solved the question in the picture in two different ways : simplification and factorisation I hope you find it useful bye:)
