Answer:
m = 5
Step-by-step explanation:
We are told that the two triangles are similar. Thus, each side of the larger triangle is the same multiple of the corresponding side in the smaller triangle.
Thus, 12 = k(7.2), where k is the constant of proportionality.
Solving this for k, we get
k = 12/7.2 = 1 2/3
Thus, side m is 1 2/3 times 3, or 5/3 times 3, or just 5.
m = 5
Answer:
So lets isolate y
we have
-2x+3y=9
2/3x +2y=0
Im gonna do the first equation
so -2x + 3y = 9
Add 2x on both sides
3y= 9+ 2x
Now divide by 3 to isolate y
y= 3+ 2/3x
Now we can subsitute y into any eqaution (I’m gonna do the second one) to solve.
2/3x+ 2(3+ 2/3x)= 0
Solve:
2/3x+ 6 + 4/3x = 0
6/3x +6= 0
2x+6=0
2x= -4
x= -2
Now we can subsitute this for any equation.
so I’m gonna do the first equation
-2(-2)+3y=9
4+3y=9
3y= 5
y= 5/3
y= 1 2/3
Final answer:
x=-2
y= 1 2/3
Answer:
<u>The dimensions of the real store are 80 times bigger as per scale:</u>
- 1.875 in * 80 = 150 in = 150/12 ft = 12.5 ft
- 2.25 in * 80 = 180 in = 180/12 ft = 15 ft
<u>The area of the real store:</u>
- 150 in * 180 in = 27000 in²
- 12.5 ft * 15 ft = 187.5 ft²
