Mathematics
1 answer:
Lelu [443]3 years ago
6 0

Answer:

Step-by-step explanation:

The equations that she wrote are

6x+8y=133

2x=y

The following statements about the system are true

1.Since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133

5. The second equation is correct because there are more 6 inch pies and 2 times a number is always more.

The following statements are wrong because,

2. Because there was no relationship between the number of pipes sold and the size of each pipe.

3. x=2y shows that there are more 8 inches pipes

4. 6 and 8 are just size descriptions. It is only the cost of each size of pipe that related to the total cost

Can someone please help me solve this? <br><br> 2x+5y=-1 <br><br> -10x-25y=5
fredd [130]

this is system of equations

2x + 5y = -1   times this one by 5 to make the y's opposite

-10x -25y = 5

10x - 25y = -5  (this is it times by 5, now add them)

__________

0 + 0       = 0    

now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.

padilas [110]

The  expressions that could represent how much Leila pays in total for the model

\dfrac{107}{100}x

100 107 Option A is correct.

This is further explained below.

<h3>Which of the following expressions could represent how much Leila pays in total for the model?</h3>

The price of the model is  x

Now we are given that she also has to pay a 7  tax.

Amount of tax =7 % x

=\frac{7}{100} x

the Total cost=x+\frac{7}{100} x

=\frac{107}{100} x

In conclusion, the statement might signify Leila's overall cost for the model. \frac{107}{100} x
