Write an expression for: the product of 3 and the quantity of a number minus 7

"The product" immediately suggests multiplication; we're going to be multiplying two quantities together, "3" and "a number minus 7"

"A number" just describes an unknown value, so we'll pick the letter n to be that unknown in our expression. "A number minus 7" then could be written as n - 7.

We can now write the product of 3 and (n - 7) as the expression

3 × (n - 7)

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
