The number 4 is apart of the sequence, but it has been taken away by 3.
3+4=7. Since it was taken away by 3, we have to add 7 by 3 to get 9. So on and so forth.

Not long after he begins to study algebra he will likely meet with the "tank" problems, the "labor" problems and many other puzzle problems. He finds these problems carefully phrased in the language of practical mathematics. However, a study of the original problems and the fanciful way in which they were stated will reveal the fact that they were originally intended mostly for puzzles. The present-day student of algebra would doubtless work as industriously over the so-called practical problems if he were told they were puzzle problems that his predecessors had worked on for the past 1600 years.
The problems given below are selected from a collection made by Metrodorus about 310 A. D. found in The Greek Anthology. It is not known how much farther back they date. It will not be difficult for the reader to trace many of the problems found in the present-day algebras back to their original source. He may judge for himself as to whether the modern text-book writer has improved the problems by leaving off the little fanciful touches of rhetoric, found in the original.
The original problems were solved by rhetorical algebra as our symbols, +, -, ×, ÷, etc., were introduced many centuries later, about 1540.

Step-by-step explanation:
Marco went to the cafeteria to buy chicken sandwiches, C, worth $2.00, and hamburgers, h, worth $2.50.
He bought a total of 9 items and spent a total of $20.50. How many hamburgers and chicken sandwiches
did Marco buy?
HELP
Answer:
5 Hamburgers = $12.50 4 Chicken sandwiches $8.00( $12.50 + $8.00 = $20.50
Step-by-step explanation:
Answer:
Marco bought 5 hamburgers and 4 chicken sandwiches.
Step-by-step explanation:
Set up a system of equations:
2c + 2.5h = 20.5
c + h = 9
Solve by elimination by multiplying the bottom equation by -2:
2c + 2.5h = 20.5
-2c - 2h = -18
Add the equations together and solve for h:
0.5h = 2.5
h = 5
So, he bought 5 hamburgers. Plug in 5 as h into the second equation to solve for c:
c + h = 9
c + 5 = 9
c = 4
So, Marco bought 5 hamburgers and 4 chicken sandwiches.

Answer:
50
Step-by-step explanation:
120 +angle1 = 180 angle 1 is 60 70+60+angle2 should be equals 180 so 2 is 50 degree
1 is 60 degree 3 is 80 degree 4 is 100 degree 2 is 50 degree
60+40 +angle3 = 180 angle3 is 80
3+4 should be equal 180 3 is 80 180-80= 100 4 is 100
number 10?? please help.
Answer:
∠GFM= 124°
Step-by-step explanation:
∠GFH= 180° -90° -(5x +9)° (∠ sum of △FGH)
∠GFH= 90° -5x° -9°
∠GFH= (81 -5x)°
∠GFM +∠GFH= 180° (adj. ∠s on a str. line)
25x -1 +81 -5x= 180
20x +80= 180 (simplify)
20x= 180 -80 (-80 on both sides)
20x= 100
x= 100 ÷20 (÷20 on both sides)
x= 5
∴∠GFM
= 25x -1
= 25(5) -1
= 124°
The ratio of the sides of two similar rectangles is 3:5. The larger rectangle has an area of 36 sq. cm. What is the area of the smaller rectangle?
Answer:
21.6 sq cm
Step-by-step explanation:
3:5
x:36
cross-multiply because they are in proportion
x*5=3*36
divide both sides by 5
x= 3*36/5=21.6

Jose can use the rule m(x)=10+3x to find m(x) , the amount of money he will have after a week of doing x additional hours of chores. Evaluate m(20), What does this mean?
Answer:
70
Step-by-step explanation:
Given:
m(x) = 10 + 3x
where,
m(x) = the amount of money he will have after a week of doing x additional hours of chores
x = additional hours of chores
Evaluate m(20), What does this mean?
m(x) = 10 + 3x
m(20) = 10 + 3(20)
= 10 + 60
= 70
m(20) = 70
m(20) means additional hours of chores is 20

Kyle plans to make 15 hamburger patties, each weighing 14 pound, for a cookout. At the store, hamburger meat is priced at $3.66 per pound. If Kyle orders the exact amount of meat he needs, how much will it cost, rounded to the nearest cent?
Answer:
Total cost= $768.66
Step-by-step explanation:
Giving the following information:
Production= 15 units
Standard quantity= 14 pounds per unit
Standard cost= $3.66 per pound
First, we need to calculate the total pounds required to make the hamburgers:
Total pounds= 14*15
Total pounds= 210 pounds
Now, the total cost:
Total cost= 210*3.66
Total cost= $768.66

Claire wants to build a patio outside her café. The rectangular space outside of Claire's café is three times as long as it is wide. The area of the space is 48 m2. Claire
would like to build a patio with dimensions 3.5 m by 12.5 m in this space. Will it fit? Explain.
pls help
Answer:
Step-by-step explanation:
It will fit in the space but it won't cover the entire space. the area is 48m2, but the patio in question will cover 43.75 of the 48m2. Also, it stated that the rectangular space is 3 times as long, and the patio is 3.57x as long as the width. So yes, it will fit, but it will not be a picture perfect fit, there will be some obscenities.
Step-by-step explanation:
Let length of space be lm and width be wm.
l = 3w --(1)
lw = 48 --(2)
sub (1) into (2):
3w(w) = 48
3w^2 = 48
w^2 = 16
w = ± 4 (rej -4 since w > 0)
when w = 4, l = 3(4) = 12
Since dimensions of the patio is 3.5m by 12.5m, and the dimensions of the space is 4m by 12m it does not fit
