Which statement best describes the expression 2y ÷ 7?

A. 2 times y divided by 7

B,C and D are obviously wrong.It doesn't related on the equation given.A is the right answer

The work of a student to find the dimensions of a rectangle of area 8 + 16x and width 4 is shown below:

A. Step 1: 8 + 16x
B. Step 2: 4(4) + 4(12x)
C. Step 3: 4(4 + 12x)
D. Step 4: Dimensions of the rectangle are 4 and 4 + 12x

In which step did the student first make an error and what is the correct step?

C. Step 2; 4(2) + 4(4x)

The first error is at the step 2.It doesn't show the right solution.4(4x),not 4(12x).That is obviously wrong.How could 16 can be 12 even the expression not multiply by any number yet ! that obviously WRONG. C is the right answer

In the following you may leave your answer as a binomial or multinomial coefficient. In each case give a brief justification for

Simora [160]

Answer: a) 792 ways b) 13⁷.

Step-by-step explanation:

Since we have given that

Number of apples to be given = 5

Number of bananas to be given = 7

Number of people = 12

So, Number of ways that each person gets a pieces of fruit is given by

$\dfrac{12!}{7!\times 5!}\\\\=792\ ways$

b) If the number of people = 13

Number of apples to be given = 7

So, Number of ways would be

$13\times 13\times 13\times 13\times 13\times 13\times 13\\\\=13^7$

Hence, a) 792 ways b) 13⁷.

Bryan and his son, and Elton and his son all went fishing. Bryan caught as many fish as his son and Elton caught three times as

Annette [7]

Answer:

The answer is explained below

Step-by-step explanation:

This is a word problem, therefore to solve it the statement have to be writing in form of an equation and then solved.

Let the number of fishes caught by Bryan's son be x fishes. Since Bryan caught as many fish as his son, Bryan caught x fishes

Let the number of fishes caught by Elton's son be y fishes. Since Elton caught three times as many fish as his son, Bryan caught 3y fishes

All together, they caught 25 fish

Therefore it can be represented by the equation:

x + x + y + 3y = 25

2x + 4y = 25

2x = 25 - 4y

x = (25 - 4y)/2

The number of fish caught by Bryan is half of the difference between the total fish caught and four times the number of fish caught by Elton son
