Divide the second price by the second pounds. 9.95 / 5 = 1.99
So for every pound you get you pay 1.99 dollars. The second deal is better.
Answer is the first, second and the fourth one.. replace a number with variable, two operation are multiplication and addition, then the expression is written as 4n+7...
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
1. 1 – n = 0.
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>
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> Julia = 15 apples Niccole = 2Julia
Hence, 2Julia = 2(15) = 30 apples.
Four points which lie at (0,0) ; (0,2) ; (2,2) ; (2,0)
What is the figure formed?What is the area of the figure?
The given points lie on graph as per the order given in the attachment.
Which shape?
As the points lie 2 units apart from their adjacent sides. It can be a square or rhombus.
The opposite pairs of sides are also parallel to each other. The adjacent sides of the figure formed are also perpendicular to each other.
<u>Hence! the figure formed is a square.</u>
What is the area?
