A wire 23 cm long is cut into two pieces. The longer piece is 7 cm longer than the shorter piece.

Flura [38]

Length of a wire = 23 cm

Given that :

▪︎The wire was cut into two pieces.

▪︎The longer piece of wire is 7 cm longer than the shorter piece of wire.

Let the shorter piece of wire be x.

Then, the longer piece of wire = x+7

An equation that can be derived from these statements :

▪︎x + x + 7 = 23

Let us solve this equation :

$= \tt x + x +7 = 23$

$= \tt 2x + 7 = 23$

$= \tt 2x = 16$

$= \tt x = \frac{16}{2}$

$\color{plum} \hookrightarrow \color{plum}x = 8$

Thus, the value of x = 8.

Which means :

Length of the shorter piece of wire = 8 cm

Length of the longer piece of wire = 8 + 7 = 15 cm

Since the length of the two wires add up to form 23 cm(8+15=23), we can conclude that we have found out the correct measures of each wire.

Therefore, the length of the shorter piece of wire = <u>8 cm</u>

Y is seven times the value of x.

ANTONII [103]

Answer:

$y = 7x$

Step-by-step explanation:

Look at the term:

"y is seven times the value of x."

This term means that whatever x is, y is always going to be 7 times greater than that number. Meaning that x needs to always be multiplied by 7 to get y, easy.

Make 7 the coefficient.

$7x$

$7x = y$

Henry wants to avoid interest capitalization on his $7,800 unsubsidized Stafford loan. Henry will graduate in four years, and th

hichkok12 [17]

<span>Interest capitalization means adding the interest to the principal balance. To avoid that you need to keep the balance at or below $7800. Let's assume Henry wants to pay the minimum amount necessary to avoid interest capitalization. Then, since it compounds monthly at an APR of 5.6%, each month a certain amount is added to the balance. That amount should be the yearly interest rate divided among the months in the year. Multiply that number by the principal to see how much interest accrues at the end of each month. That's what Henry needs to pay.</span>
