I need 10x+3y=19 and y=2x+5 solved algebraically

taurus [48]

Y=2x+5
sub 2x+5 for y in other equaiton
10x+3(2x+5)=19
distribute
10x+6x+15=19
minus 15 from both sides
16x=4
divide both sides by 16
x=1/4
sub back

y=2x+5
y=2(1/4)+5
y=1/2+5
y=5.5=11/2

solution is (1/4,11/2) or in decimal, (0.25,5.5)

Let x represent the regular price of any book in the store. Write an expression that can be used to find the sale price of any b

arsen [322]

Answer:

(a) The sale price of any book in the store is 0.70 <em>x</em>.

(b) The regular price of the book bought by Jerome was $12.80.

Step-by-step explanation:

The complete question is:

All books in a store are being discounted by 30%. Let x represent the regular price of any book in the store. (a) Write an expression that can be used to find the sale price of any book in the store. (b) Jerome bought a book on sale at the store. The sale price of the book was $8.96. Write an equation to determine the regular price of the book Solve your equation to find the regular price of Jerome's book to the nearest cent.

Solution:

The regular price of any book in the store is denoted by, <em>x</em>.

(a)

The discount percentage is: <em>d</em>% = 30%.

The sales price of the book is:

Sales Price = Regular Price - Discount

$SP =x-(x\times 30\%)$

$=x-0.30x\\=0.70x$

Thus, the sale price of any book in the store is 0.70 <em>x</em>.

(b)

The sales price f book bought by Jerome is, SP = $8.96.

Jerome bought the book at the same discount, i.e. 30%.

Compute the regular price of the book bought by Jerome as follows:

$SP =x-(x\times 30\%)$

$8.96=0.70x$

$x=\frac{8.96}{0.70}$

$=12.80$

Thus, the regular price of the book bought by Jerome was $12.80.

A track star in Arizona ran the 100 meter dash event is six track meets. Her average time for all six meets was 11.8 seconds. Sh

natima [27]

Answer:

A track star in Arizona running time in the last meet was 11.5 seconds.

Step-by-step explanation:

Given:

average time for all six meets = 11.8 seconds.

Time for 1st meet = 11.7 seconds.

Time for 2nd meet = 11.6 seconds.

Time for 3rd meet = 12 seconds.

Time for 4th meet = 12.1 seconds.

Time for 5th meet = 11.9 seconds.

We need to find the running time for her last meet.

Solution:

Let the running time for her last meet be 'x'.

So we can say that;

average time for all six meets is equal to sum of Time for 1st meet, Time for 2nd meet, Time for 3rd meet,Time for 4th meet, Time for 5th meet and time for her last meet and then divided by 6.

framing in equation form we get;

$\frac{11.7+11.6+12+12.1+11.9+x}{6}=11.8\\\\\frac{59.3+x}6 =11.8$

Now Multiplying both side by 6 we get;

$\frac{59.3+x}{6}\times 6= 11.8\times6\\\\59.3+x=70.8$

Now Subtracting both side by 59.3 we get;

$59.3+x-59.3=70.8-59.3\\\\x=11.5 \ s$

Hence A track star in Arizona running time in the last meet was 11.5 seconds.
