Answer:

It is impossible to know the solution of this expression unless you know how much a is worth or some information on the other side of the equation. If you don't know what I mean then I'll explain it a bit more. An equation is 2 expressions that are equal to each other but here I don't know anything about the other side of the equation. For example, an equation like this: 3a - 15= 6 is solvable because I know enough information to solve this.

3a - 15 + 15= 6 + 15

3a = 21

Therefore I can now find out what the answer is but your equation does not have enough information for it to be solved.

A total of 715 tickets were sold for the school play. They were either adult tickets or student tickets. There were 65 more stud

Sergeeva-Olga [200]

Answer:

There were 423 adult tickets sold.

Step-by-step explanation:

Let x = the number of adult tickets sold

Let x + 65 = the number of student tickets sold

x + x + 65 = 715

2x = 715

x = 357.5

x + 65 = 422.5 (round up)

Answer: -0.5.

Step-by-step explanation:

The constant of variation k for the direct variation is given by:-

$k= \dfrac{f(x_2)}{x_2}=\dfrac{f(x_1)}{x_1}$

The given table:

x f( x )

0 0

2 -1

4 -2

7 -3.5

Then,

$k=\dfrac{-1}{2}=\dfrac{-2}{4}=\dfrac{7}{-3.5}=-0.5$

Hence, the constant of variation k for the direct variation is -0.5.

Draw a model to represent the ratio 1 to 3. Describe how to use the model to find an equivalent ratio. Please help I'm really st

Gnesinka [82]

Answer: See below

Step-by-step explanation:

Make a table with first set of numbers as 1,3. Multiply both the numbers of this set sequentially by natural numbers to get the following table

1 2 3 4 5 6 7 8 9 10......

3 6 9 12 15 18 21 24 27 30......

We see that in each set of numbers the 2nd number is 3 times the first number.

If we plot these sets of numbers on a graph paper, we get a model depicting all the points which satisfy this ration requirement.
