Answer:

Hailey's Work

Step-by-step explanation:

Hailey's work is the correct option for this one because:

- The statement specifies that we need to find the quotient of a number and 7, in that order, and Hailey has written it like this: n/7, making the statement valid.

- Quotient represents division, you will need to divide n by 7 in order to get the quotient.

Based on your formatting, I didn't get quite what you wrote, but I did the best I could.

In each of the following ,make y the subject and hence find the value of y when a=2, b=3 ,and c=4.
zvonat [6]

Part i


\dfrac{2a-7}{6y} = \dfrac{3b-5}{2c}


y = \dfrac{ 2c(2a-7)}{6(3b-5)} = \dfrac{c(2a-7)}{9b-15}


Substituting,

y = \dfrac{4(2(2)-7)}{9(3)-15} = \dfrac{ -12}{12} = -1


Answer: -1


Part ii


I'm not sure that one's typed in correctly but I'll solve it as written.


3-34y + 2a = \dfrac{3b-5}{2c + 1}


34y  = 3+2a-\dfrac{3b-5}{2c + 1}


y = \frac 1 {34}\left(3+2a-\dfrac{3b-5}{2c + 1} \right)


We're not asked to simplify it so I wont. Substituting,


y = \frac 1 {34}\left(3+2(2)-\dfrac{3(3)-5}{2(4) + 1} \right) = \frac 1 {34}(7-4/9) = \dfrac{59}{306}


Answer: 59/306

Answer:

right

neither

straight

neither

Step-by-step explanation:

The first angle is a right angle.  The box in the corner indicates a 90 degree angle

The second angle is less than 90 degrees so it is an acute angle

The third angle is a straight line so it is a straight angle.

The fourth angle is wider than 90 degrees  it is an obtuse angle

V125BC [204]
Lets assume the whole pie is 1, that is all fractions added together have to sum 1.
If Victor eats 1/6 out of 5/6, then the rest is 4/6 of the pie, that is the subtraction of those fractions.
