how many solutions does x + 2x + 7 = 3x - 7
Answers
Answer:
No solutions! :)
Step-by-step explanation:
To find the number of solutions in a problem we must solve it.
x+2x+7=3x-7
Firstly, combine common terms:
3x+7=3x-7
We can subtract 3x from both sides:
7=-7
The solution is 7=-7, which is no solution.
When a number is equal to a number in a solution, it has no solutions!

In this formula, what is the meaning of the term (1-0.125)?
Α. The value of the system will decrease by 12.5% each year.
.
В. The value of the system will be $0 in 12.5 years.
С The value of the system will decrease by $12.50 each year.
DThe value of the system will continue to decrease for 125 years.
Answers
Answer: c
Step-by-step explanation:
The term ( 1 -0.125) is a decay factor which means the value of system decreased by 12.5% each year.
What is exponential decay?The process of reducing an amount by a consistent percentage rate over a period of time is called exponentially decay.
Exponentially decay rate formula[tex]y = a(1-r)^{x}[/tex]
a is initial amount
1-r is decay factor
x is time period
According to the given question.
We have a exponential function.
[tex]V = 100,00(1-0.125)^{y}[/tex]
If we compare the above function with exponential decay rate formula i.e.
[tex]y = a(1-r)^{x}[/tex]
We get,
a = 100,000
r = 0.125
In [tex]V = 100,000(1-0.125)^{y}[/tex], the term ( 1 -0.125) is a decay factor which means the value of system decreased by 12.5% each year.
Thus, option A is correct.

[tex]\text{State Income Tax Rate: }6.65\%, \\\text{Deduction: }\$7,702.03[/tex]
Answer:
State income tax: [tex]6.65\%[/tex]
Step-by-step explanation:
Based on the interface, it seems like you have chosen lawyer as a career with the given salary of $115,820.
The chart given for state income tax is broken into two categories:
$21,400-$80,650 => 6.45%
$80,651-$215,400 => 6.65%
Since the chosen career's salary is $115,820, the career falls into the second range of 6.65% state income tax.
The deduction is simply the amount of money taxed. For a 6.65% state income tax, the deduction can be found from:
[tex]115,820\cdot 0.0665=\boxed{\$7,702.03}[/tex]

5(y+25)=−13 what is y
Answers
Answer:
y = -27.6
Step-by-step explanation:
To solve for y, you need to isolate the variable on one side of the equation. [tex]5(y+25)=-13[/tex] ⇒ [tex]y + 25 = -2.6[/tex] ⇒ [tex]y = -27.6[/tex].
Answer:
-27.6
Step-by-step explanation:
[tex]5(y + 25) = -13[/tex]
First, distribute the problem.
[tex]5y + 125 = -13[/tex]
Secondly, subtract 125 from -13 and 125.
[tex]125 - 125 = 0[/tex]
[tex]-13 - 125 = -138[/tex]
Now, we are left with 5y = -138.
Lastly, we divide -138 by 5.
[tex]-138 / 5 = -27.6[/tex]
Therefore, y is -27.6.

Answers gotten wrong = 11
answers gotten right = 40 - 11 = 29

The vertex angle of an isosceles triangle is three times the measure of either base angle. Find the area if the measure of the congruent sides are 14 in
Answers
Answer:
[tex]Area = 93.21in^2[/tex]
Step-by-step explanation:
Given
[tex]\theta \to[/tex] vertex angle
[tex]\alpha \to[/tex] base angle
[tex]\theta = 3\alpha[/tex]
[tex]l = 14in[/tex] -- congruent sides
Required
The area of the triangle
First, calculate the angles
[tex]\theta + \alpha + \alpha = 180^o[/tex] ----- angles in an isosceles triangle
Substitute [tex]\theta = 3\alpha[/tex]
[tex]3\alpha + \alpha + \alpha = 180^o[/tex]
[tex]5\alpha = 180^o[/tex]
Divide both sides by 5
[tex]\alpha = 36^o[/tex]
Recall that: [tex]\theta = 3\alpha[/tex]
[tex]\theta = 3 * 36^o[/tex]
[tex]\theta = 108^o[/tex]
The area is then calculated as:
[tex]Area = \frac{1}{2}l^2 \sin(\theta)[/tex]
[tex]Area = \frac{1}{2}*14^2 \sin(108^o)[/tex]
[tex]Area = \frac{1}{2}*196 *0.9511[/tex]
[tex]Area = 93.21in^2[/tex]

Answers
then the straight line that h and 92° is on =180 so we can use that to solve for h. so 180-92=88. so h =88.
same rules apply to the lower intersection. k=91° and 91+m=180. so m=89°
Answer:
g. 92*
h. 88*
m. 89*
k. 91*
Step-by-step explanation:
To find h and m: All of the angles on a straight line added up equals 180*. So if there are two angles, the sum of them must equal 180* (angle A + angle B = 180*)
So in this case we have angle h + 92* = 180* using algebra, we subtract 92 from both sides and we get angle h = 88*
If you want to check, add 92 + 88 = 180.
Also angle m + 91* = 180*. Same thing as above, subtract 91 from both sides and we get angle m = 89*
If you want to check, add 91 + 89 = 180.
When you have two straight lines intersecting (crossing), the opposing angles at that crossing are going to be equal. So in this case angle g is opposite from the anbgle that we know is 92*, so angle g is also 92*. Same thing for angle k, we know the angle opposite angle k is 91*, so we know that angle k is also 91*.

The answer to your question is 26.75
Step-by-step explanation:
Top triangle = 3.5 x 9 = 31.5. Since it is a triangle, it has to be split in half (15.75).
Bottom left triangle = 2 x 2 = 4. Since this is also a triangle: 4 split in half is 2.
Bottom square = 2 x 2 = 4.
Bottom right triangle = 5 x 2 = 10. Since it is a triangle, 10 / 2 = 5.
After you get the area of each individual shape, add them together to get 26.75.
