Answer:
0.08 or 8%
Step-by-step explanation:
to find probability, number of left handed/total
this would be (9+3)/(90+60), which simplifies to 12/150 = 0.08.
Answer:
$1210
Step-by-step explanation:
Let x be total amount
First John spent $110 on a radio and 4/11 of what was left on presents for his friends so he was left with
Then he put 2/5 of his remaining money into a checking account
Rest he donated to charity
Hence total amount of money John originally had was $1210
The terms would be 4a and another would be 6b squared.
The coefficient (a number or quantity placed before the variable, which is the letter) of 4a is 4. The coefficient of 6b squared would be 6
If the perimeter is known / given and is 6x, you can find the length of the unknown side by adding up the lengths of the other two sides and subtracting this sum from 6x:
6x - (x+3 + 2x + 4) = 6x - x - 3 - 2x - 4
Combining like terms, 3x - 7 represents the length of the unknown 3rd side.<span />
$45 is 20% of $225
45 x 100 = 4,500 / 225 = 20
