Intersecting chord rule:
DK x KB = AK x CK
12 x 4x+1 = 14 x 3+3x
Simplify:
48x +12 = 42x +42
Subtract 12 from each side:
48x = 42x + 30
Subtract 42x from each side:
6x = 30
Divide both sides by 6:
x = 5
Now find the length of KB: 4x +1 = 4(5) +1 = 20 +1 = 21
Now add KB and AK:
21 + 14 = 35
The answer is D. 35
A1) Using estimate, the solutions to the following are:
A) is -14.
B) is 31.
C) is 38.
D) is -74.
1. The remaining amount in Brock's account after writing the checks is <u>$2,290</u>.
2. Linda put <u>$831</u> in her savings account after meeting her expenses.
<h3>What is an estimate?</h3>
An estimate is a rough calculation.
To do an estimate, the figures may be appropriated or rounded up.
<h3>Estimates:</h3>
A. –42.3 ÷ 3.4
= -14 (–42 ÷ 3)
B. 16.1 – (–14.7)
= 31 (16 – (–15)
C. –15.52 + 54.25
= 38 (–16 + 54)
D. ‐67.8 ‐ 5.72
= -74 (‐68 ‐ 6)
<h3>Brock:</h3>
The amount in Brock's checking account = $3,084
<u>Checks</u>:
Rent $350
Auto repair $275
Loan payment of $169
Total amount for checks = $794
Remaining amount = $2,290 ($3,084 - $794)
<h3>Linda:</h3>
The total amount of the paycheck = $2,312
<u>Expenses</u>:
Rent $157
Food $322
Child care $478
Transportation $234
Miscellaneous expenses $290
Total expenses = $1,481
Savings account = $831 ($2,312 - $1,481)

Put them all over a common denominator
So 13/4 - 22/4 + 9/4 = 0/4 or just 0
27= 3n? Im confused because normally I would say ''3n'' but the 'y' is included. Look back at the notes?
