180-3x =x (corresponding angles are equal)
x=45°
11)180-5x=3x ( same reason)
x=10°
12)180-6x=3x(same reason)
x=20°
Answer: See explanation
Step-by-step explanation:
10) Same side interior angles add up to 180°
3x + x = 180
4x = 180
x = 45
11) Same side interior angles add up to 180°
5x + 3x = 180
8x = 180
x = 22.5
12) 6x is vertical to an angle that has a relationship with 3x (same side interior angles) which means 6x and 3x have to add up to 180° as well
6x + 3x = 180
9x = 180
x = 20

If Debbie starts a retirement account with 10,000 dollars that has an annual rate of return of 12%, how long (in years) would it take for her to have at least 100,000 dollars if interest is compounded continuously?
Answers
Answer:
19.2 years
Step-by-step explanation:
The formula to find the time in a compound interest that is compounded continuously is given as:
t = ln(A/P) / r
Where:
t = time in years = ??
A = Amount after Interest is compounded continuously = $100,000
P = Initial Amount in the retirement account = $10,000
r = Rate of return = 12%
First, convert R percent to r a decimal
r = R/100
r = 12%/100
r = 0.12 per year,
Then, solve our equation for t
t = ln(A/P) / r
t = ln(100,000.00/10,000.00) / 0.12
t = 19.188 years
Approximately t = 19.2 years

Chihuahuas and Yorkies. There are four
times as many Chihuahuas as Yorkies.
Using c for Chihuahuas and y for Yorkies,
determine which equation may be
used to represent this situation.
c=4+y
y=4+c
y=4c
c=4y
Answers
Answer:
c = 4y
Step-by-step explanation:
Are there more, Chihuahuas or Yorkies?
Does the word 'times' mean add, subtract, multiply or divide?
The way I look at it, there are more Chihuahuas and 'times' means multiply. Do you agree?
Therefore, I need to multiply 4 times the no. of Yorkies to get the no. of Chihuahuas
So, c = 4y
Now, I don't see an equation in the list to choose from. So, I don't know what to do from here. I am guessing that c = 4y is what you want.

Chazmire purchases 14 bags of flour for her bakery.Each bag of flour cost $2.47. How much does chazmire soend for flout
Answers
Answer:
$34.58
Step-by-step explanation:
If each bag of flour cost $2.47, then;
1 bag = $2.47
To calculate the cost of 14bags;
14 bags = x
x is the cost of 14 bags
Divide both expressions
1/14 = 2.47/x
cross multiply
1 * x = 14 * 2.47
x = $34.58
Hence Chazmire spent $34.58 on flour

*5. Gina's sister is 9 years older than Gina. Their combined ages add up to
49. How old is Gina? *
A. 29 years
B. 20 years
C. 19 years
D. 9 years
Answers
Answer:
B. 20 years
Step-by-step explanation:
By using the process of trial and error, if Gina is 20 years old, that would mean her sister is 29 years old. This is because 20+9 is equal to 29. 29+20 sums up to 49.
Answer: B. 20 years
Step-by-step explanation:
we will represent Gina sister's age by x and Gina's age by y.
Now were know that the age of Gina sister is 9 years older than Gina's so we can represent that by the equation x = y + 9
If we add their ages it is 49 so we can also represent that by the equation,
x + y = 49.
x = y + 9
x + y = 49
Using both equations, substitute x in the first equation into the second equation and solve for y.
(y + 9) + y = 49 solve for y , by first combining like terms.
2y + 9 = 49 subtract 9 from both sides
-9 -9
2y = 40 divide both sides by 2
y = 20
Since y was used to represent the age of Gina then Gina will be 20 years old.
