2x=28
4x-9=47
you solve for x after you add all the sides
Greetings from Brasil...
The perimeter is the sum of all sides of the triangle. In this case
P = (2X) + (X) + (4X - 9)
as P = 89
89 = (2X) + (X) + (4X - 9)
89 = 7X - 9
7X = 98
X = 98/7
X = 14X:
X meters = X = 14
---------------------------------------------
2X:
2X meters = 2 · X = 2 · 14 = 28
---------------------------------------------
(4X - 9):
(4X - 9) meters = (4 · X - 9) = (4 · 14 - 9) = (56 - 9) = 47

According to the model, Leo's initial deposit was $0
According to the model, how many dollars was Leo's initial deposit?The model is given as
a = 18t + 5
When he makes his initial deposit, the value of t is
t = 0
i.e. this represents his balance before he starts saving on a weekly basis
Substitute 0 for t in the equation a = 18t + 5
So, we have
a = 18 * 0 + 5
Evaluate
a = 5
Hence, Leo's initial deposit was $0

Andrea, Dina, and Lindsay invested in a partnership in the ratio of 7:9:14, respectively.

nearest dollar.
b. What percent of the business did Andrea own after she bought out Dina? Round to
the nearest tenth of a percent.
c. What was the new ratio of ownership once the business was owned by only Andrea
and Lindsay?
ina
Answers
The new ratio of ownership once the business was owned by only Andrea and Lindsay is 8 : 7
a. How much did Andrea pay Dina for her share of the partnership?The ratio is given as:
Andrea : Dina : Lindsay = 7 : 9 : 14
The partnership worth is given as
Worth = $1,800,000
The amount received by Dina is:
Dina = Dina Ratio/Total Ratio * Worth
So, we have
Dina = 9/(7 + 9 + 14) * 1800000
Evaluate
Dina = 540000
Hence, Andrea pays Dina $540,000 for her share of the partnership
What percent of the business did Andrea own after she bought out Dina?Initially, we have:
Andrea : Dina : Lindsay = 7 : 9 : 14
So, the new ratio is
Andrea : Lindsay = (7 + 9) : 14
Evaluate
Andrea : Lindsay = 16 : 14
As a percentage, we have
Andrea = 16/(16 + 14) * 100%
This gives
Andrea = 53.33%
Hence, Andrea owns 53.33% of the business after she bought out Dina
What was the new ratio of ownership once the business was owned by only Andrea and Lindsay?In (b), we have:
Andrea : Lindsay = 16 : 14
Simplify
Andrea : Lindsay = 8 : 7
Hence, the new ratio of ownership once the business was owned by only Andrea and Lindsay is 8 : 7

B)
x = 3∕7, –7∕3
C)
x = 7∕3, –7∕3
D)
x = 7∕9, –7∕9
Answers
The solutions to the quadratic equation, -9x² + 49 = 0, are: C. x = 7∕3, –7∕3.
How to Find the Solutions to a Quadratic Equation?Given the quadratic equation, -9x² + 49 = 0, we can factorize to find the roots (the values of x) as shown below:
-9x² + 49 = 0
-(9x² - 49) = 0
Divide both sides by -1
-(9x² - 49)/-1 = 0/-1
9x² - 49 = 0
9x² - 49 + 49 = 0 + 49
9x² = 49
Divide both sides by 9
9x²/9 = 49/9
x² = 49/9
Take the square root of both sides
√x² = √(49/9)
x = ±7/3
Therefore, the solutions to the quadratic equation, -9x² + 49 = 0, are: C. x = 7∕3, –7∕3.

What's the current temperature? 5 + (-12) = ?
Answers
Answer:
-7
Step-by-step explanation:
To add a positive number, 5, and a negative number, -12, take the absolute value of both numbers.
You get 5 and 12.
Subtract the smaller absolute value from the larger absolute value.
12 - 5 = 7
The sign of the answer is the same sign as the number that has the larger absolute value. The absolute of 5 is 5. The absolute value of -12 is 12. -12 has the larger absolute value, and -12 is negative, so the answer is negative.
5 + (-12) = -7

Find the slope of (8,9) and (23,9)
Answers
Step-by-step explanation:
you mean the slope of the line between (8, 9) and (23, 9).
we can see that right away, as the y value does not change. it means it is a flat line, and that means the slope is 0.
now, formally :
the slope of a line is (y coordinate change / x coordinate change) when going from one point on the line to another.
the direction does not matter, but once we pick one for the comparison of one coordinate, we have to use the same direction also for the other.
I prefer to go from left to right.
so, from (8, 9) to (23, 9).
x changes by +15 (from 8 to 23).
y changes by 0 (from 9 to 9).
the slope is therefore 0/+15 = 0.

150 is 96 percent of what number
Answers
Answer:
Step-by-step explanation:
Comment
Let the unknown number = x
You should try and figure out if x is bigger than 150 or less than 150.
The equation will tell you.
96/100 * x = 150 96/100 = .96 So you will get something larger than 150 for x
Combine
96/100 = 0.96
Equation
.96*x = 150 Divide by 0.946
.96x/.96 = 150/0.96
Answer
x = 156.25
And as predicted, the answer is larger than 150, because you were dividing by a number less than 1
the peremiter of a parallelogram is 56 meters The width of the parallelogram is 4 meters less than its length find the length and the width of the parallelogram
Answers
The length of the parallelogram is 16 m and the width of the parallelogram is 12 m.
We are given that the perimeter of a parallelogram is 56 m.
Let the length of the parallelogram be x meter.
So, we get that the width of the parallelogram will be = x - 4 meter.
We also know that:
Perimeter of parallelogram = 2 ( l + b )
Substituting the values in this, we get that:
56 = 2 ( x + x - 4 )
56 = 2 ( 2 x - 4 )
28 = 2 x - 4
2 x - 4 = 28
2 x = 28 + 4
2 x = 32
x = 16
Length = 16 m
Width = 16 - 4 = 12 m
Therefore, the length of the parallelogram is 16 m and the width of the parallelogram is 12 m.
