Step-by-step explanation:
You certainly cannot. This is because you can really only determine size from how many gallons it holds, and shape can differ as long as it can hold the amount needed. Hope this helps.
Answer:
<h2>2.3 < x < 8.7</h2>
Step-by-step explanation:
Look at the picture.
We have a = 5.5, b = x and c = 3.2.
Substitute:
(1)
5.5 + x > 3.2 <em>subtract 5.5 from both sides</em>
x > - 2.3
(2)
5.5 + 3.2 > x
8.7 > x
(3)
x + 3.2 > 5.5 <em>subtract 3.2 from both sides</em>
x > 2.3
From (1), (2) and (3) we have:
2.3 < x < 8.7
Answer:
y = -4
Step-by-step explanation:
Combine the y terms. To do this, add 0.3y to both sides, which results in:
5.1y + 0.3y = -21.6, or
5.4y = -21.6
Dividing both sides by 5.4 yields the desired result:
y = -21.6/5.4 = -4
