<span>To write algebraic expressions to model quantities is you base the algebraic expressions or mathematical values declared in words by the manner of how the sentence illustrates the said problem. For example, one minus a number is the difference of zero shall be </span>
<span>1. 1 – n = 0. </span>
<span>Other same examples, John bought 25 apples while Julia bought only 15 from the market. If Niccole bought twice as much as Julia’s, how many was Niccole’s apples? </span><span><span>
1. </span>You state the problem by the sequence of the said problem and understanding the possible structure.</span> <span><span>
2. </span>Solution will be</span><span> Julia = 15 apples Niccole = 2Julia </span>
<span>Hence, 2Julia = 2(15) = 30 apples.<span>

Answer:
8 29/42
Step-by-step explanation:
5/6 + 7 6/7 = 35/42 + 7 36/42 = 7 71/42 = 8 29/42
Answer:
A=52.8 miles (approximately)
Step-by-step explanation:
We can assume that this triangle is not a right angle, therefore we cannot use Pythagorean theorem. Let's use the Law of Sines:
Where A is unknown, a=28 miles, b=32 miles, B=87°
Therefore by law of sines we have:
By multiplying 28 to Isolate sin(A) we have:
To cancel out sine on the right, we must multiply both by the inverse sine and so:
Answer:
C.0, 500
Step-by-step explanation:
Answer:
All real numbers except the number zero
Step-by-step explanation:
we know that
Observing the graph
The range is the interval
(-∞,0) U (0,∞)
The number zero is not included in the range
therefore
All real numbers except the number zero
