Answer:
16x=1 x=1/16 or 0.0625
2/5x=1 x=5/2 or 2.5
Step-by-step explanation:
for 16x=1 divide both sides by 16, 1 divided by 16 is 1/16 or 0.0625
for 2/5x=1 multiply by the reciprocal of 2/5 which is 5/2. 5/2 times 1 is just 5/2 or 2.5.
(x+6)(x+2)
Simplifying
(x + 6)(x + 2)
Reorder the terms:
(6 + x)(x + 2)
Reorder the terms:
(6 + x)(2 + x)
Multiply (6 + x) * (2 + x)
(6(2 + x) + x(2 + x))
((2 * 6 + x * 6) + x(2 + x))
((12 + 6x) + x(2 + x))
(12 + 6x + (2 * x + x * x))
(12 + 6x + (2x + x2))
Combine like terms: 6x + 2x = 8x
(12 + 8x + x2)
Answer:
D 28 inches
Step-by-step explanation:
mean : average
So to find the mean add all of the numbers in April and divide by the total number of different heights there were:
(12+15+23+11+12+19+20+12+11+14+12+13) ÷ 12 = 14.5
Do the same for the heights in June:
(42+45+44+39+45+45+40+43+41+40+45+41) ÷ 12 = 42.5
Then subtract the means to find the difference:
14.5 - 42.5 = -28
Since its a real world problem the answer can’t be negative
Therefore the answer is D 28 inches
The answer is D because they must extract 14 tons to meet their obligations. If they extract 2 tons per hour, they must work at least 7 hours.
