Use the quations 2L + 2W = Area
and L = 3W -4
Plug the second equation into the first and solve for W
2(3W-4) + 2W = A
6W - 8 + 2W= A
8W - 8 = A
8W = 8
W = 1
Then plug that into the second equation
L = 3(1) -4
L = 3 -4
L = -1
Then plug both of the answers into the first equation
2(-1) + 2(1) = A
-2 + 2 = A
0 = A
That should be the answer, but since there was no given Area, i'm not sure.
I hope this helped though!
Answer:
Given that A cereal manufacturer decides to offer a new family-sized box based on the regular-sized box. They want the volume of the family-sized box to be three times the volume of the regular-sized box. However, they want the length of the family-sized box to be the same as the regular-sized box.
If original dimensions are l,w and h then volume = lwh
Volume of new box is= 3lwh
But here w becomes 2w and l remains the same. Let h' be the new height
Then we have
So by 1.5 factor height should be dilated.

Answer:
x = 9, y = 2 is the solution of the given system.
Step-by-step explanation:
Here, the given set of equation is :
2 x - 3 y = 12
x = 4 y + 1
Now, from equation (2) we see that x = 4 y + 1.
Substitute the value of y from (2) in the first equation. we get:
2 x - 3 y = 12 ⇒ 2 (4 y + 1) - 3 y = 12
or, 8 y + 2 - 3 y = 12
or, 5 y = 12- 2 = 10
or, y = 10/ 5 = 2
or, y = 2
Now, x = 4 y + 1 ⇒ x = 4(2) + 1 = 8 + 1 = 9, or x = 9
Hence, x = 9, y = 2 is the solution of the given system.

Answer:
$4
Step-by-step explanation:
30+20=50
50-48=2
2+20+=22
22-18=4
if she has 30 then gets 20 she has 50. Then she spends 48 dollars leaving her with only 2 dollars. She then makes another 20 dollars so she now has 22 dollars. She spends 18 dollars leaving her with 4 dollars.
