The given statement written in symbolic language is x = 3y + 4 and x + y = 72 where "x" is the cost of one book and "y" is the cost of another book
<em><u>Solution:</u></em>
Given that Bruce bought two books
One book costs $ 4.00 more than three times the other
Let the two books be denoted as Book A and book B
Let "x" be the cost of book A
Let "y" be the cost of Book B
From given,
One book costs $ 4.00 more than three times the other
Let Cost of book A = $ 4.00 more than three times the other book B
x = 4 + 3 times cost of Book B
x = 4 + 3y
x = 3y + 4 --- (i)
Also given that Together, the two books cost him $72
cost of book A + cost of Book B = 72
x + y = 72 ------- (ii)
Therefore the given statement written in symbolic language is:
x = 3y + 4 and x + y = 72
Answer:
-16
Step-by-step explanation:
it's right I promise
29. 5/2× 2/5×=5/2×7 multiply the equation by the reciprocal of the coefficient
x= 5/2×7/1 <span> reduce the numbers with 5,2. convert the expression into a fraction
</span><span>
x= 5</span>×7/2×1
<span>
x= 35/2
32. a= 19/6
2 3/4a = 19 1/4 divide both sides of the equation by 1/4
2</span>×3a=19 calculate the product <span>
</span>
6a=19 divide both sides by 6
a=19/6
