3w)w = 24in^2 (Tossing out the negative solution for unit measure)
3w^2 = 24
w^2 = 8
w = 2√2in and L = 6√2in L+=+3w
P = 2L + 2w = 16√2in
<span>7x-4y=-7
5x+y=22
multiply 4 on the 2nd equation
</span>20x+ 4y=88
now you have
7x -4y = -7
20x + 4y = 88
--------------------add
27x = 81
x = 3
7x-4y=-7
7(3)-4y=-7
-4y = -28
y = 7
answer (3, 7) is the solution

Greetings!</h2>
If x = the first number (equal to 1x) then the second number is 75% more than this.
This means the value of the bigger number is 100 + 75 (because 100 is the starting number and 75 is the percent bigger)
This can be shown with the following equation:
Amount * 
x *
= 1.75x
1.75x is the value of the bigger number.

Answer:
-2.3 repeating
Step-by-step explanation:
30/150 = 80/x
Reduce the fraction:
1/5 = 80/x
Cross multiply:
x = 5 x 80
x= 400
Answer: 400 zebras.
