Answer:
each number in the ratio 4:5:7 is worth 6 sweets. add 4,5, and 7 to get 16 then multiply it by 6 to get 96 sweets.
Step-by-step explanation:
add the ratios = 4+5+7= 16
1 number = 6 so
4x6= 24
5x6=30
7x6=42
Frank gets 24 sweets
Mary gets 30 sweets
Seth gets 42 sweets
The total number of sweets they shared is 24+30+42= 96
The share 96 sweets altogether.
The check your answer; do 42-24= 18
Therefore, now we know that the difference between Seth and Frank's amount of sweets is 18.
Therefore, this is correct.
2x^2+2xy+2x
The ^ means exponent
In an equilateral triangle all the sides are equal. This means that all the angles add up to 180 degrees.
Divide 180 by 3 and you get 60.
You want an exterior angle so you cut the angle in half ( it is now 30 )
Because the base and the line are parallel (form right angle if drew line connecting them) x is equal to
90-30=60
$676.
If the sale price of the coat is $169, you are looking for the original price. I like to think about it in the sense that if an item is 75% off, you are paying 25% of the original amount. Using that logic, in order to determine the sale price you would use the equation
Original price * 25% = $169
To solve for the original price:
Original price = $169/.25 = $676.
