Answer: A)
B) 75%
C) She bought 1.5 dozen of plain bagels and 0.5 dozen of sesame bagels.
Step-by-step explanation:
Given: The ratio of the number of sesame bagels to the number of plain bagels is 1:3.
Let the number of sesame bagels be x and the number of plain bagels be 3x.
Then total bagels=x+3x=4x
A) The fraction of bagels are plain
B) The percent of bagels are plain
C) If ill bought 2 dozen bagels, the number of plain bagels
The number of sesame bagels
Hence, she bought 1.5 dozen of plain bagels and 0.5 dozen of sesame bagels.

v=8
2.)x/3-10=-12
x/3-10=-12
x/3=-2
x=-6
3.) x/4+10=14
x/4=4
x=16
Monthly amount, M = $102×4 = $408.
Also, yearly amount, Y = M×12 = $408×12 = $4896
It is given that 25% of the cost is contributed by Marcus.
Amount Marcus paid
Therefore, his employer contribution annually for coverage is $( 4896 - 1224)=$3672.
Hence, this is the required solution.
Answer:
C. (3x2 - 10) (x - 2)
Step-by-step explanation:
3x^2 - 16x +20
Step 1: Sum = - 16x
Product = 60x^2
Step 2: Find 2 numbers that their sum is -16 and their product is 60. If you do that correctly, then you will get two numbers: 10 and -6
Step 3: Replace -16x with the two numbers found in step 2, then you will have; 3x^2 - 6x - 10x + 20
Step 4: Factorise the equation in step 3, like so;
(3x^2 - 6x)(- 10x + 20)
3x(x - 2) -10(x - 2)
(3x - 10)(x - 2)
To check if the answer is correct, expand the bracket: (3x - 10)(x - 2)
If the bracket is opened properly, you will get 3x^2 - 16x + 20
