Answer:

No Ms Chen is not correct and the price is $1.99 per pound

Step-by-step explanation:

Ms Chen is not correct because she did the division wrong. She was supposed to divide the price by the pounds but she divided the pounds by the price. The correct way of doing this would be dividing $12.95 by 6.5 which gets you 1.99230769 but since this is money that rounds to $1.99 per pound

Two complementary angles are represented by x and x+14 . find the value of x

qaws [65]

Answer:

$x=38\textdegree$

Step-by-step explanation:

Remember that complementary angles <em>always </em>add up to 90°.

We know that the two complementary angles are represented by (x) and (x+14). In other words:

$(x)+(x+14)=90$

So, let's solve for x.

First, combine like terms:

$2x+14=90$

Let's isolate the x by subtracting 14 from both sides:

$(2x+14)-14=(90)-14$

The left cancels. Subtract on the right:

$2x=76$

Divide both sides by 2:

$\frac{2x}{2}=\frac{76}{2}$

The left side cancels. Divide on the right:

$x=38\textdegree$

So, the value of x is 38°.

And we're done!
