Answer:
40. 3+2x4-1=10
39. 3+2x4+1=12
38. (3+2)x4+1=21
37. 2+3x4-1=13
Step-by-step explanation:
a.) 1/2n 4=3−5/n b.) 1/2(n 4)=5/n−3 c.) 1/2(n 4)=3−5/n d.) 1/2n 4=5/n−3
Let's assume the number be n.
So, sum of number and four can be written as n+4.
Now one-half of n+4 will be
.
Quotient of five and the number can be written as
.
Now three less \frac{5}{n} can be written as \frac{5}{n} -3.
So, one-half the sum of a number and four is three less than the quotient of five and the number can be converted into equation as follows:

So, b is the correct choice.
X5 • (3x3 - 2) • (4x + 5)
