Answer:

Therefore the Final Solution is  x = 2 and y = 7  

i.e (2 ,7)

Step-by-step explanation:

Given:

-2x+y=3                ...............Equation ( 1 )

-3x+y=1                 ...............Equation ( 2 )

y=3x+1                   ..............Equation ( 3 )

To Find:

x = ?

y = ?

Solution:

Substituting Equation  ( 3 ) in Equation ( 1) we get

-2x+3x+1=3\\\\x=3-1\\\\\therefore x =2

Now Substituting x = 2 in Equation ( 3 ) we get

y=3\times 2+1=6+1\\\\\therefore y=7

Therefore the Final Solution is  x = 2 and y = 7  

i.e (2 ,7)

Ben has 50 drinks and paid 2$ for each. What is 67% of the final price ?
Debora [2.8K]

67% of final price is $67.

Step-by-step explanation:

Given,

Number of drinks Ben has = 50

Amount paid for each drink = $2

Amount paid for 50 drinks = 50*2

Amount paid for 50 drinks = final price = $100

67% of final price = \frac{67}{100}*100

67% of final price = \frac{6700}{100}

67% of final price = $67

67% of final price is $67.

Help me plz thank you
nevsk [136]

Answer:

1) Distance=Speed*time

90=(x+1)*(x)+(2x+5)(x-1)

90=x^2+x+2x^2-2x+5x-5

3x^2+4x-95=0

2) 3x^2+4x-95=0. Using quadratic formula, we get

x=(-4±sqrt(16-4*3*(-95)<u>)</u>)/6, x=5 or - 19/5 but since x also represents time, it can't be negative.

3) Total time take she took for the journey is x+x-1=2x-1=2*5-1=9 hours

Amber got a raise, and her hourly wage increased from $8 to $9.50 what is the percent increase
I am Lyosha [343]

Answer:

The percent increase is <u>18.75%</u>.

Step-by-step explanation:

Given:

Amber got a raise, and her hourly wage increased from $8 to $9.50.

Now, to find percent increase.

Previous wage = $8.

Wage raised = $9.50.

So, to get the increased wage we subtract the previous wage from the wage raised:

\$9.50-\$8=\$1.50.

Now, to get the percent increase:

\frac{1.50}{8} \times 100

=\frac{150}{8}

=18.75\%.

Therefore, the percent increase is 18.75%.
