(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:

c

Step-by-step explanation:

Two sum of any two side lengths of a triangle will always be greater than the length of the remaining side

a doesn't work because 8+12=20 and 20 is not greater than 20

b doesn't work because 4+5=9 and 9<10

d doesn't work because 6+6=12 and 12 is not greater than 12

c is the only option where you can take any two sides, add them, and the sum will be greater than the remaining side.

For example, for c,

6+8=14, and 14>10

8+10=18, and 18>6

10+6=16, and 16>8
