Answer:
You know that a value is a soloution to a problem when you add the value into the problem to check if it solves the problem. :)
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
You would divide it by pie r squared to get h then flip the equation around so it would be
h= v/ pie r squared
All 3 of these would result in the same answer. You can see this by looking at the cross products that would be created for each of them.
In each proportion, you would get a variation of 37 times 7 = 4 times x, when you multiply the numerator of the first by the denominator of the second and the denominator of the first by the numerator of the second.
Answer:
x = -2, 1/2
Step-by-step explanation:
Step 1: Isolate everything to 1 side
2x² + 3x - 2 = 0
Step 2: Factor
(2x - 1)(x + 2) = 0
Step 3: Find roots
2x - 1 = 0
2x = 1
x = 1/2
x + 2 = 0
x = -2
Answer:
63?
Step-by-step explanation:
2 times 12 times 8 is 192.
192 -3= 189
189 divided by 3 = 63
