Greetings!
"Write and solve an equation to determine how many servings of this item ...exactly 45 grams of cholesterol"...
The
variable in this equation would be the
amount of servings she can eat of the items.
Lets represent this as

;

=amount of servings
The item has
30 mg of cholesterol and she wants to only consume
45 mg.
The equation would be:

Solve for
x.
Divide both sides by
30.

Simplify.

Alisa can consume
1.5 servings of the item each day.
Hope this helps.

ok, we need to factor the expression

since the expression divisible by y-2, then

since 6=2k, then k=c=3
Answer:
D. 27 square feet per hour
Step-by-step explanation:
Step 1:
Find the unit rate. Since 18 tiles are per 2/3 of an hour, we can divide 18 by 2 to get 9 tiles layed per third hour.
Step 2:
Multiply the 9 per third of an hour by 3 to find how many are per hour,
square feet per hour
This is called finding the unit rate of a scenario.
