For three consecutive years, Sam invested some money at the start of the year. The first year, he invested x dollars. The second year, he invested $2,000 less than times the amount he invested the first year. The third year, he invested $1,000 more than of the amount he invested the first year.
During the same three years, Sally also invested some money at the start of every year. The first year, she invested $1,000 less than times the amount Sam invested the first year. The second year, she invested $1,500 less than 2 times the amount Sam invested the first year. The third year, she invested $1,400 more than of the amount Sam invested the first year.
If Sam and Sally invested the same total amount at the end of three years, the amount Sam invested the first year is $?
and the amount Sally invested the last year is $?
.
Answers
Answer:
sam invested 4000 dollars the third year
Answer:
To answer we let x be the amount of money that Sam invested during the first year.
Below are the expressions translated from the given word forms for the amount invested.
Sam:
2nd year : amount = 5x/2 - 2000
3rd year : amount = x/5 + 1000
The sum of money invested by Sam is:
x + (5x/2 - 2000) + (x/5 + 1000)
Similarly, we derive the expressions that we use for the amount that Sally invested.
Sally
1st year : amount = 3x/2 - 1000
2nd year : amount = 2x - 1500
3rd year : amount = x/4 + 1400
The total amount that Sally invested is,
total = (3x/2 - 1000) + (2x - 1500) + (x/4 + 1400)
Equating the two equations:
(x) + (5x/2 - 2000) + (x/5 + 1000) = (3x/2 - 1000) + (2x - 1500) + (x/4 + 1400)
Solving for x,
x = 2000
For Sally's investment in the third year:
amount = x/4 + 1400 = (2000/4 + 1400) = 1900
ANSWERS:
Sam's first year = $2000
Sally's third year = $1900
At a magazine, the ratio of
• artists to photographers is 3:2.
• photographers to writers is 1:3.
• writers to editors is 2:1.
There are 9 artists. How many
photographers, writers, and
editors does the magazine have?
Answers
Answer: 33
Artists : photographers = 3 : 2, and there are 9 artists, so there are 6 photographers. Then, the ratio of photographers to writers is 1 : 3, so there are 18 writers. Finally, there are half as many editors as writers, so there are 9 editors.
There are 6 + 18 + 9 = 33 photographers, writers and editors total.

when it was new?
Answers
Answer:
$18,760.76
Step-by-step explanation:
16000 * 0.0545 = 872
16000 + 872 = 16872
16872 * 0.0545 = 919.52
16872 + 919.52 = 17791.52
17791.52 * 0.0545 = 969.64
17791.52 + 969.64 = 18760.76

Step-by-step explanation:
Congruent: If two figures are congruent, they have the same shape and the same size.
Therefore, if the given triangles are congruent, the measures of their angles and sides will be the same (equal).
To find the value of x that will result in ΔLMN≅ΔPQR, equate the measure of angle P and angle L, then solve for x:
⇒ m∠P = m∠L
⇒ (7x - 4)° = (4x + 17)°
⇒ 7x - 4 = 4x + 17
⇒ 7x - 4 + 4 = 4x + 17 + 4
⇒ 7x = 4x + 21
⇒ 7x - 4x = 4x + 21 - 4x
⇒ 3x = 21
⇒ 3x ÷ 3 = 21 ÷ 3
⇒ x = 7
Substitute the found value of x into the expression for angle L to find m∠L:
⇒ m∠L = (4(7) + 17)°
⇒ m∠L = (28 + 17)°
⇒ m∠L = 45°
Interior angles of a triangle sum to 180°.
Therefore, to find the value of y, sum the angles of ΔLMN and equate to 180° to find the measure of angle N:
⇒ m∠L + m∠M + m∠N = 180°
⇒ 45° + 84° + (2x + y)° = 180°
⇒ 129° + (2x + y)° = 180°
⇒ 129° + (2x + y)° - 129° = 180° - 129°
⇒ (2x + y)° = 51°
⇒ 2x + y = 51
Substitute the found value of x and solve for y:
⇒ 2(7) + y = 51
⇒ 14 + y = 51
⇒ 14 + y - 14 = 51 - 14
⇒ y = 37
Conclusion
The value of x that will result in congruent triangles is [tex]\boxed{\sf 7}[/tex] .
The value of y that will result in congruent triangle is [tex]\boxed{\sf 37}[/tex] .

Find the scope by counting
Answers
Answer:
-6
Step-by-step explanation:
to find slope by counting you just count rise over run
to get from (1,-4) to (0,2) you must go up 6 and back 1
6/-1 (negative cause you went back)
Answer:
Step-by-step explanation:
How is the slope (or gradient) usually found?
[tex]m = \frac{\Delta y}{\Delta x}[/tex]
In other words, this means that the slope is found by dividing the change in y by the change in x.
How many units change in regards to y? We can count! Let's start counting from the y-intercept (the red dot that on the y-axis). 2,1,0,-1,-2,-3,-4. We counted -6 since we went down.
Now let's count the change in x, if we start from the y-intercept once more, how many units do we have to move to get to the second red dot? Well that's 1! We only have to move one square to the right to get to the second red dot.
Let's plug this into the equation I stated at the start of this answer
[tex]m = \frac{-6}{1}[/tex]
And we know that [tex]\frac{-6}{1}[/tex] is just equal to -6.
Therefore, the slope of this line is -6!
Good luck!

the ratio of birth to the population of a certain town last year was 32:1000
I) if the number of birth in the town was 384 children, what was the number of population in that town
Answers
Answer and Step-by-step explanation:
We are told that the birth-population ratio last year was 32:1000
This year, it is 384. This number was multiplied by 12 from 32.
So, we should multiply 1000 by 12, which results us with 12000.
So, the ratio would be:
384:12000

if Santiago is 5 feet tall and 11 inches tall and Michael is 5 feet tall and 2 inches tall, what is their total height in centimeters rounded to the nearest centimeter? There are 2.54 centimeters in 1 inch
Answers
Answer:
337.82 cm
Step-by-step explanation:
Santiago is 5 feet tall and 11 inches tall and Michael is 5 feet tall and 2 inches tall.
We need to find total height in cm.
1 inch = 2.54 cm
1 feet = 30.48 cm
5 feet 11 inches = 5(30.48) + 11(2.54)
= 180.34 cm
5 feet 2 inches = 5(30.48) + 2(2.54)
= 157.48 cm
Total height = Santiago's height + Michael's height
= 180.34 cm + 157.48 cm
= 337.82 cm
Hence, their total height is 337.82 cm.

Explanation:
Numerator: a^2 - b^2 = (a+b)(a-b) in this case a = x and b = 5
Denominator: a times c (2 times 15 equals) 30, b is equal to 13... we must find numbers that goes equals both of these, we will use 10 and 3. 10 times 3 equals 30 and 10 plus 3 equals 13. Therefore we get 2x^2 + 10x +3x +15 which goes to 2x(x+5) + 3(x+5) which then goes to (2x+3) + (x+5)
