"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 $x$ ; $x$ =amount of servings

The item has 30 mg of cholesterol and she wants to only consume 45 mg.

The equation would be:
$30x=45$

Solve for x.
Divide both sides by 30.
$(30x)/30=(45)/30$
Simplify.
$x=1.5
$

Alisa can consume 1.5 servings of the item each day.

Hope this helps.

The price of a TV rose from $350 to $371 in one<br> month. By what percent did the TV price rise?

lesantik [10]

6% increase

To calculate the percentage increase:
First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

If your answer is a negative number, then this is a percentage decrease.

well, we know the ceiling is 6+2/3 high, and Eduardo has 4+1/2 yards only, how much more does he need, well, is simply their difference, let's firstly convert the mixed fractions to improper fractions and then subtract.

$\stackrel{mixed}{6\frac{2}{3}}\implies \cfrac{6\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{20}{3}} ~\hfill \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{20}{3}-\cfrac{9}{2}\implies \stackrel{using ~~\stackrel{LCD}{6}}{\cfrac{(2\cdot 20)-(3\cdot 9)}{6}}\implies \cfrac{40-27}{6}\implies \cfrac{13}{6}\implies\blacktriangleright 2\frac{1}{6} \blacktriangleleft$
