Which ordered pair is the solution to the system of linear equations y=-7X+2 and y = 9%-14?

Dmitriy789 [7]

Answer:

y = -7x + 2

y = 9x - 14

-7x + 2 = 9x - 14

14 + 2 = 9x + 7x

16 = 16x

1 = x

y = -7x + 2

y = -7(1) + 2

y = -7 + 2

y = -5

solution is : (1,-5)

There are 450 seats in the lower level of a concert hall with b balcony seats in the upper level. So far, 170 tickets have been

slamgirl [31]

There are 400 balcony seats in the concert hall.

<u>Step-by-step explanation</u>:

Step 1 :

The number of lower seats = 450 seats

Total seats = Lower seats + balcony seats

Step 2 :

Tickets sold = 170 tickets
Total tickets = x

Tickets sold = 1/5 of total tickets.

⇒ 170 = (1/5)x

⇒ x = 5 $\times$ 170

⇒ x = 850 tickets

∴ Total seats in the concert hall is 850.

Step 3 :

Total seats = 450 + balcony seats

850 - 450 = balcony seats

∴ balcony seats = 400

Caroline was thinking of a number. Caroline halves the number and gets 7.3. Form an equation with x from the information.

Damm [24]

Answer:

The equation is: $\frac{x}{2} = 7.3$

Step-by-step explanation:

Caroline was thinking of a number.

We are going to call this number x.

Caroline halves the number and gets 7.3.

To find half of a number, we multiply by 1/2. So

$\frac{1}{2} \times x = 7.3$

$\frac{x}{2} = 7.3$
