Answer: a = 15
Step-by-step explanation:
6a + 10 = 3a + 55
Subtract 10 from both sides
6a = 3a + 45
Subtract 3a from both sides
3a = 45
Divide each side by 3
a = 15
1800 divided by 25 is 72. He types 72 words per minute.
32+20=52 so there are 52 people in all.
32/52 people are men.
we now have to subtract 1 from this fraction like so 32-1/52-1 since the magician took away 1 man from the audience (therefore reducing the amount of men as well as the audience as a whole) resulting in 31/51
we multiply 32/52 with 31/51 to get 248/663. simply turn this fraction into a percent by multiplying the quotient by 100 and rounding it to the nearest tenth to get 37.4%
Answer:
Area = length x width
width = 1/2 length = 12/2 = 6 = width
area = 6x 12 = 72
