Answer:
21
Step-by-step explanation:
42% of 42 is 84% of what number
Let the number be y
42% of 42 is 84% of y
NOTE: Of means multiplication
42/100 × 42 = 84 /100 × y
1764/100 = 84y/100
cross multiply over the equal sign
176400 = 8400y
divide by 8400
176400/8400 = 8400y/8400
y = 21
To verify
42% of 42 is 84% of a number
42% of 42 is 84% of y
42/100 × 42 = 84/100 × 21
1764/100 = 1764/100
17.64 = 17.64
Answer: x= 17°
Step-by-step explanation:
The two measures have to add up to 180 degrees.
(7x -1) + (5x -23) = 180 combine like terms on the left side
12x - 24 = 180 add 24 to both sides
+24 +24
12x = 204 Divide both sides by 12
x = 17
