Let n be the first integer, then n+2 is the following integer. Then,

(n+n+2)/4=189.5

Solve the equation to find n=378

189.5= (n+n)÷4 you would set up sort of like a proportion to solve
189.5 = (n+n)÷4. you would divide each side by 4 because you are doing pemdas backwards so 189.5÷4= 47.37
47.37 = n+n
and you know n and n are the same so divide 47.37 by 2 to get 23.68
23.68=n

Paula got $10.50 from her grandparents on her birthday. She earned $4.45 by babysitting. How much money is this in all? c HAPPY

Aloiza [94]

We have the following:

To calculate the total money, you have to add the amounts that Paula won, as follows

$\begin{gathered} T=10.5+4.45 \\ T=14.95 \end{gathered}$

Which means that in total they are $ 14.95

Estimate the limit.

Bezzdna [24]

Answer:

a. 0.25

Step-by-step explanation:

The given expression is

$\lim_{x \to 2} \frac{x-2}{x^2-4}$

Factor the denominator using difference of two squares.

$\lim_{x \to 2} \frac{x-2}{(x-2)(x+2)}$

Cancel out common factors;

$\lim_{x \to 2} \frac{1}{(x+2)}$

We plug in 2 to get

$\lim_{x \to 2} \frac{1}{(x+2)}=\frac{1}{2+2}$

$\lim_{x \to 2} \frac{1}{(x+2)}=\frac{1}{4}=0.25$
