Answer:
x = 5.75
Step-by-step explanation:
4^(x+7) = 8^(2x-3)
But; 4^(x+7) = 2^2(x+7)
8^(2x-3) = 2^3(2x-3)
2^2(x+7) = 2^3(2x-3)
Since the bases are the same;
2(x+7) = 3(2x-3)
2x + 14 = 6x -9
14 + 9 = 6x - 2x
23 = 4x
x = 23/4
<u>x = 5.75</u>
Let's define each choice to differentiate which is the answer
A. Equivalent - equivalent equations may not look exactly the same on face value. But they are equivalent because they have the same exact solution.
B. Expressions - expression is a general term for equations that are formed from word problems
C. Equal - equal equations are the exact duplicate of each other
D. Similar - this term is only used on geometric shapes to tell that the two shapes have a fixed ratio of their similar sides or angles
E. Radical - radical equations are those involving fractions
Therefore, from their descriptions, the answer is A.
Answer:
3/4
Step-by-step explanation:
dividing by a fraction is the same as multiplying by its reciprocal.
Therefore,
(1/2) / (2/3) = (1/2) * (2/3) = (3/4)
Answer:
black
Step-by-step explanation:
because
The answer is: "
27.5 pages " ; or, write as: "
27
pages " .
____________________________________________________________5.5 pages / 12 minute = ? pages / 60 minutes;
12 * 5 = 60 ;
5.5 * 5 = ?
5.5 * 5 = 27.5
____________________________________________________________The answer is: "
27.5 pages " ; or, write as: "
27
pages " .
