Please help me with this question!!!

Rasek [7]

The unit rate is $2.75

If you divide the cost by Movies/week you would always get $2.75

For example:

11÷4=2.75

13.75÷5=2.75

19.25÷7=2.75

22÷8=2.75

Hope this helps you :))

Elina [12.6K]

You need do like 25$--------100% of real price
x$---------70%

25x70=100x
1,750=100x
 x=1750divided by 100=17.5$

Solve the system of linear equations. separate the x- and y- values with a coma.

kobusy [5.1K]

Solve the following system:
{7 x - 3 y = 37 | (equation 1)
{14 x + 11 y = 23 | (equation 2)
Swap equation 1 with equation 2:
{14 x + 11 y = 23 | (equation 1)
{7 x - 3 y = 37 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{14 x + 11 y = 23 | (equation 1)
{0 x - (17 y)/2 = 51/2 | (equation 2)

Multiply equation 2 by 2/17:
{14 x + 11 y = 23 | (equation 1)
{0 x - y = 3 | (equation 2)

Multiply equation 2 by -1:
{14 x + 11 y = 23 | (equation 1)
{0 x+y = -3 | (equation 2)
Subtract 11 × (equation 2) from equation 1:
{14 x+0 y = 56 | (equation 1)
{0 x+y = -3 | (equation 2)

Divide equation 1 by 14:
{x+0 y = 4 | (equation 1)
{0 x+y = -3 | (equation 2)
Collect results:
Answer: {x = 4
{y = -3

What is the value of x? Enter your answer in the box.

Liono4ka [1.6K]

Answer:

x = 80 degree

Step-by-step explanation:

As sum of all angles in a triangle is equal to 180

so:

According to the given figure:

70 + 30 + x = 180

By simplifying

100 + x = 180

x = 180 - 100

x = 80 degree

i hope it will help you!
