Answer:
x = 11.2
Step-by-step explanation:
-5x - 12y = -8
5x + 2y = 48
you can combine all like terms from both equations together:
0x-10y=40
simplified:
-10y=40
y=-4
now you plug in the value of y into either equation:
5x+2(-4)=48
simplify
5x-8=48
add 8
5x=56
divide by 5
x=56/5=11.2
Use the pythagoras theorem to find the number of blocks between Shakillah's and Reyna's house
= sqrt (12^2+ 5^2) = aqrt 169 = 13 blocks
distanc,e from school to Shaquilla's house = 12 - 0 = 12 blocks
.. .. .. .. .. ... .. Reyna's house = 5 -0 = 5 blocks
So total number of blocks in entire trip = 5 + 12 + 13 = 30
Answer:
C(s) = total cost function
$5,500 base price to rent trucks
$250 per ton of sugar to be transported
Total Cost = Price per ton of sugar * # of tons + total cost to rent trucks
C(s) = $250s + $5,500
For 14 tons of sugar the total cost would be:
C(s) = $250(14 tons) + $5,500
C(s) = $9,000
Total cost to transport 14 tons of sugar would cost $9,000
