Measure of angle ABD, and you know measure of angle ABC = 4x-1.

4(1)-1 = 4-1 = 3

A 14​-foot piece of string is cut into two pieces so that the longer piece is 2 feet longer than twice the shorter piece. If the
Maurinko [17]
We are given that the shorter piece is x
From your description, the longer piece is 2x + 2
The total length is
x + 2x + 2 = 14
ie
3x + 2 = 14
3x = 12
x = 4

So the length of the shorter piece is 4 ft
Therefore the length of the longer piece must be
(14 - 4) ft = 10 ft

Seiji and Gavin both worked hard over the summer. Together they earned a total of $525. Gavin earned $25 more than Seiji.
Korolek [52]

<u>Answer:</u>

Seiji’s earning = $250;

Gavin’s earning = $275

<u>Explanation:</u>

Consider Seiji’s earning to be $x

According to question, Gavin earned $25 more than Seiji

Then, Gavin’s earning = x + $25

According to question, total earning is $525

Then, x + x + 25 = 525

Solving for x,

2x + 25 = 525

2x = 500

x = 250

Therefore, Seiji’s earning, x = $ 250

Gavin’s earning = 250+25 = $275
