In second equation add 0.74 and y to both sides: 3.25x+0.74=y;
Substitute y in the first equation: -4.5x-2(3.25x+0.74)=-12.5;
Distribute multiplication over addition:
-4.5x-6.50x -1.48=-12.5;
Combine like terms and add 1.48 to both sides:
-11x= -12.5+1.48;
-11x= 11.02 divide both sides by -11;
X= -11.02/11= -1.00(18)
Y= 3.25• -1.00(18)+.74= -2.515(90)
Answer: 87m
Step-by-step explanation:
This problem can be solved by using a simple ratio and proportion.
The way you figure this out is:
Model = 12 m/ 1 cm = x/7.25 cm
Solve for x and you should receive this answer:
x = 87 m

Answer:
Howdy! Let me see if I can be of assistance.
This is a triangular prism that we must solve for, and there are a few steps that can guarantee you land on the right answer.
1) Plug the base and height numbers into the formula, where V is volume:
V= 1/2 × base × height
which becomes
V= 1/2 × 6 × 10
Note that either of the base numbers will work, since the ratio is the same.
2) multiply both of those numbers by 1/2 and you will have your answer! I leave that to your capable hands.
P.S. remember to put the answer down as centimeters squared
