Rashaj has $37.25 in his wallet. He would
Butoxors [25]

I agree. From the calculation, the total <em>amount spent </em><em>is </em><em>less than</em><em> (<)the amount in his pocket</em>, this means that <em>Rashaj can buy 5 boxes of candy. </em>

Inequalities are expressions that are not always equal to each other. The inequality signs are <, > ≤ and ≥

Given the following

Amount Rashaj has in his wallet = $37.25

Amount spent

A movie ticket = $7.25

5 boxes of candy at $3.75 per box = 5($3.75) = $18.75

Taking the sum of the total amount spent

Amount spent = $7.25 + $18.75

Amount spent = $26

Since the total <em>amount spent </em><em>is </em><em>less than</em><em> (<)the amount in his pocket</em>, this means that <em>Rashaj can buy 5 boxes of candy. </em>

A rectangular bedroom is 4 ft longer than it is wide. Its area is 140 ft2. What is the width of the room? ft
steposvetlana [31]

Answer: width = 10 ft

Step-by-step explanation:

Area = length × width

Let l be length and w be width

l = w + 4 ........equation (1)

From above formula

140 = l × w. ........equation (2)

Substitute equation (1) into equation (2)

140 = (w+4) × w

w^2 + 4w= 140

w^2 + 4w - 140= 0

By factorization method

(w+14)(w-10)= 0

w=-14 or w= 10

So now width is 10 ft

From equation(1)

l=w+4

l= 10+4

l= 14 ft

Width = 10 ft and length = 14 ft
