There are 4 quarts in a gallon, so multiply 20 x 4 to get 80.
The aquarium can hold 80 quarts.
Hope I helped!
Answer:
x=-20
Step-by-step explanation:
1. Expand 3(x+8) : 3x+24
2.Expand -3(7-1/4x): -21*3/4x
3. 3x+24= -21*3/4x
4.<em>Subtract 24 from both sides</em>
3x+24-24= -21*3/4x-24
5.3x= 3/4x-45
6.<em>Subtract 3/4 from both sides</em>
3x-3/4= 3/4x-45-3/4
7.9/4x=-45
8<em>.Multiply both sides by 4</em>
9/4x*4=-45*4
9.9x=-180
10.<em>Divide both sides by 9</em>
9x/9=-180/9
11. x=-20

Answer:
Step-by-step explanation:
Two angles each =x because both are equal.
All triangles have angles adding to 180 degrees
The angle that isn't = x is 82 degrees.
x + x + 82 = 180 Subtract 82 from both sides
2x + 82 - 82 = 180 - 82 Combine
2x = 98 Divide by 2
2x/2 = 98/2
x = 49
angle 1 = 49
angle 2 = 49
angle 3 = 82
