A - 3b = 4 . . . . (1)
a = b - 2 . . . . . (2)
Putting (2) into (1), we have
b - 2 - 3b = 4
-2b = 4 + 2 = 6
b = 6/-2 = -3
From (1), a = b - 2 = -3 - 2 = -5
Hence, solution = (-5, -3)
25/28 - 2/7
it doesn’t need to be solved because it asked for an expression and not an equation, so no equal sign either
Use the formula a^(x/n) = (n)√a^x (note it is a small n)
(5x^4y^3)^(2/9) = Small 9
Convert.
is your answer
hope this helps
Answer:
The top right answer choice is correct.
2.3 x 12 = 27.6
27.6 > 27.1
Step-by-step explanation:
Well first off, we know that:
1 foot = 12 inches
To compare the two, we first want to covert 2.3 feet into inches.
2.3 x 12 = 27.6 inches
Now that we have our two values, we need to decide which is greater than the other.
27.6 or 27.1
Both values have a decimal that shows tenths. In this problem, 6 tenths is larger than 1 tenth. Therefore:
27.6 inches > 27.1 inches
