(a) System of equations are

2x+4y=14794\\3x+5y=19892\\

(b) The cost of MacBook is $2,799

The cost of iMac is $2,299

Given :

Firm purchased 2MacBook Pro notebooks and 4iMac desktops for a total order price of $14,794

they purchased 3MacBook Pro notebooks and 5 iMac desktops for a total order price of $19,892.

Let x be the cost of MacBook Pro

and y be the cost of iMac

Now frame the equation using given information

2 MacBook +4 iMac= 14794

2x+4y=14794

3 MacBook +5 iMac= 19892

3x+5y=19892

System of equations are

2x+4y=14794\\3x+5y=19892\\

To solve for x  and y , Lets solve the second equation for x

3x+5y=19892\\3x=19892-5y\\x=\frac{19892-5y}{3}

Substitute x in first equation and solve for y

2\cdot \frac{19892-5y}{3}+4y=14794\\\frac{39784+2y}{3}=14794\\\frac{3\left(39784+2y\right)}{3}=14794\cdot \:3\\39784+2y=44382\\2y=4598\\y=2299

Substitute y value in the x equation

\mathrm{\:}x=\frac{19892-5y}{3}\\x=\frac{19892-5\cdot \:2299}{3}\\x=2799

The cost of MacBook is $2,799

The cost of iMac is $2,299

Answer:

H. 260

Step-by-step explanation:

We'll begin this problem by first figuring out how many students will be able to sit at the first fourteen tables.

14 tables * 14 students = total students

196 = total students ( for those fourteen tables)

Now we also know that sixteen students can sit on the rest of the cafeteria tables.

We need to find the number of tables can hold sixteen students.

To do this, we'll lead with a simple equation:

18 tables total - 14 tables = # of remaining tables

4 = # of remaining tables

Now we're going to do the same thing we did with the original tables:

4 tables * 16 students = total students

64 = total students

Finally, we add both of the tables max values together:

64 + 196 = 260

Solve 9,159 divided by 7
aniked [119]

Answer:

(9159 / 7 = 1308.429)

Step-by-step explanation:

Simply multiply the last digit by 2 and then subtract the product from the remaining digits.

If that difference is divisible by 7, then 9159 is divisible by 7.

The last digit in 9159 is 9 and the remaining digits are 915. Thus, the math to determine if 9159 is divisible by 7 using our alternate method is:

915 - (9 x 2) = 897

Since 897 is not divisible by 7, 9159 is also not divisible by 7.

Therefore, the answer to "Is 9159 Divisible By 7?" is no.

(9159 / 7 = 1308.429)
