Answer:
$374
Step-by-step explanation:
First you need to find how much money does the back pay per year
$200*7.25
=1450
1450/100
=14.5
Secondly you need to find how much does Catherine have in 12 years
14.5*12 years
=$174
Lastly add the money she already had 12 years ago to how much the bank payed in that 12 years
$200+$174
=$374

However, I'm able to rearrange the question as:
[tex]\left[\begin{array}{ccc}1&1&1|-1\\-2&3&5|3\\3&2&4|1\end{array}\right][/tex]
Operations:
[tex]2R_1 + R_2 ->R_2[/tex]

Please note that the above may not reflect the original question. However, you should be able to implement my steps in your question.
Answer:
[tex]\left[\begin{array}{ccc}1&1&1|-1\\0&5&7|1\\0&-1&1|4\end{array}\right][/tex]
Step-by-step explanation:
The first operation:
[tex]2R_1 + R_2 ->R_2[/tex]
This means that the new second row (R2) is derived by:
Multiplying the first row (R1) by 2; add this to the second row
The row 1 elements are:
[tex]\left[\begin{array}{ccc}1&1&1|-1\end{array}\right][/tex]
Multiply by 2
[tex]2 * \left[\begin{array}{ccc}1&1&1|-1\end{array}\right] = \left[\begin{array}{ccc}2&2&2|-2\end{array}\right][/tex]
Add to row 2 elements are: [tex]\left[\begin{array}{ccc}-2&3&5|3\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}2&2&2|-2\end{array}\right] + \left[\begin{array}{ccc}-2&3&5|3\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}0&5&7|1\end{array}\right][/tex]
The second operation:
[tex]-3R_1 +R_3 ->R_3[/tex]
This means that the new third row (R3) is derived by:
Multiplying the first row (R1) by -3; add this to the third row
The row 1 elements are:
[tex]\left[\begin{array}{ccc}1&1&1|-1\end{array}\right][/tex]
Multiply by -3
[tex]-3 * \left[\begin{array}{ccc}1&1&1|-1\end{array}\right] = \left[\begin{array}{ccc}-3&-3&-3|3\end{array}\right][/tex]
Add to row 2 elements are: [tex]\left[\begin{array}{ccc}3&2&4|1\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}-3&-3&-3|3\end{array}\right] + \left[\begin{array}{ccc}3&2&4|1\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}0&-1&1|4\end{array}\right][/tex]
Hence, the new matrix is:
[tex]\left[\begin{array}{ccc}1&1&1|-1\\0&5&7|1\\0&-1&1|4\end{array}\right][/tex]

The measures of the angles of a triangle are shown in the figure below. Solve for x
75°
63°
Answer:
x = 20
Step-by-step explanation:
The sum of angle of a triangle is 180. Taking the sum of the angles and equating to 180 will give:
75 + 63 + 4x+2 = 180
138+2+4x = 180
140+2x = 180
2x = 180=140
2x = 40
x = 20
Hence the value of x is 20

for the figure shown below, find the value of the variable and the measures of the angles.
x=
measure of angle P=
measure of angle Q=
measure of angle R=
Answer:
p=58
q=84
r=38
Step-by-step explanation:
x+46+2x-18+x=180 degree ( angle sum property )
4x + 28 = 180 degree
4x = 180 - 28
4x = 152
x = 152 /4
x= 38
angle p = 2x -18 = 2 *38 -18 = 58 degree
angle q = x + 46 = 38 +46= 84 degree
angle r = x = 38 degree
Answer:
x= 38°
measure of angle P= 58°
measure of angle Q= 84°
measure of angle R=38°
Step-by-step explanation:
Equations
The sum of the internal angles of a triangle is 180°. We are given the three angles as a function of x, thus:
2x - 18 + x + 46 + x = 180
Simplifying:
4x + 28 = 180
Subtracting 28:
4x = 180 - 28 = 152
x = 152/4 = 38
x = 38°
Angle P=2x-18=2*38-18=58°
Angle Q=x+46=38+46=84°
Angle R=x=38°

Answer:
1). Area = 37 cm²
2). Area = 120 cm²
Step-by-step explanation:
Figures in the picture attached are the examples of composite figures.
1). Area of the composite figure = Area of rectangle A + Area of rectangle B
Since area of rectangle = Length × width
Area of rectangle A = 8 × 2 = 16 cm²
Area of rectangle B = 3 × 7 = 21 cm²
Area of the composite figure = 16 + 21 = 37 cm²
2). Area of the composite figure = Area of C + Area of D
= (3×4) + (9×12)
= 12 + 108
= 120 cm²

Find the x-intercept and y-intercept of the linear equation: 3x+2y=6*
Algebra
Answer:
-3/2
Step-by-step explanation:
You randomly select one card from a 52-card deckFind the probability of selecting the eight of spades or the seven of hearts
→ Probablity of getting the 8 spades = 1/52
→ Probablity of getting the 7 hearts = 1/52
Both are mutually exclusive event's.So,
⇒ Probablity of getting 7 hearts or 8 spades = Probablity of getting the 7 hearts + Probablity of getting the 8 spades
⇒ Probablity of getting 7 hearts or 8 spades = 1/52 + 1/52
⇒ Probablity of getting 7 hearts or 8 spades = 2/52
⇒ Probablity of getting 7 hearts or 8 spades = 1/26
The probability of selecting the eight of spades or the seven of hearts is 1/26.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of cards = 52
Number of eight of spades in the deck of cards = 1
Number of seven of hearts in the deck of cards = 1
The probability of selecting the eight of spades or the seven of hearts.
= 1/52 + 1/52
= 2/52
= 1/26
Thus,
The probability of selecting the eight of spades or the seven of hearts is 1/26.

solve the equation: the booster club of the baseball team bought pizza to sell at a concession stand. the school donated three pies to the sale. each pie was then cut into 8 pieces and sold . there were a total of 64 pieces to sell. how many pies did the booster club purchase
Answer:
they bought 5 pies
Step-by-step explanation:
.................
Five pies were bought by the booster club of the baseball team.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Three pies were provided for sale by the school. After that, each pie was divided into 8 pieces and sold. 64 pieces in all were available for purchase.
Let "p" be the number of pies the booster club purchased.
The school donated 3 pies, so the booster club purchased a total of p + 3 pies.
Each pie was cut into 8 pieces, so there were a total of (p + 3) × 8 = 64 pieces to sell.
This equation can be simplified to p + 3 = 8, or p = 5.
Therefore, there was a booster club that purchased 5 pies.

first, combine the like terms.
add -4x and -13x
-13-17x=-14+15x
now, add 13 to both sides

Answer:
x = 0.84375
Step-by-step explanation:
-13 - 4x - 13x = 14 + 15x
-13 - 17x = 14 + 15x
-13 - 17x + 17x = 14 + 15x + 17x
-13 = 14 + 32x
-13 - 14 = 32x
-27 = 32x
-27 / -32 = 32x / 32
0.84375 = x
Isabella and Angel are reading the same book. At the beginning of the month, Isabella was on page 35 and Angel was on page 5. Isabella will read 10 pages per day and Angel will read 20 pages per day. Let I represent the page of the book that Isabella is on at the end of t days into the month, and let A represent the page of the book that Angel is on at the end of t days into the month. Graph each function and determine after how many days, t, Isabella and Angel will be on the same page of the book.
Answer:
3 days
Step-by-step explanation: (See Annex)
According to the problem statement, both readings (Isabela and Angel) are models for a straight line:
10 and 20 are the slopes of I and A respectively
I = 35 + 10*t
A = 5 + 20*t
The common point of the two lines will be the day when they both will be on the same page ( see annex)
then:
35 + 10*t = 5 +20*t
35 - 5 = 20*t - 10*t
10*t = 30
t = 3
