Someone Plsss Help - Find X

Answers

Answer 1

Answer:

96 + 150 + 2x + x = 360⁰

240 + 3x = 360⁰

3x = 120

x = 40⁰ hope it's help you

Answer 2

Answer: 58

Step-by-step explanation:

Since the shape has 5 sides, the sum of the internal angles is (5-2)*180 = 3*180 = 540 degrees.

Therefore, 96+150+120+2x+x = 540

386 + 4x = 540

3x = 174

x = 58

Solve the system by substitution.
y = -7x+ 3
y = -8x

Answers

Answer:

x = -3, y = 24

Step-by-step explanation:

y=−7x+3;y=−8x

Step: Solve y=−7x+3 for y:

y=−7x+3

Step: Substitute−7x+3 for y in y=−8x:

y=−8x

−7x+3=−8x

−7x+3+8x=−8x+8x(Add 8x to both sides)

x+3=0

x+3+−3=0+−3(Add -3 to both sides)

x=−3

Step: Substitute−3 for x in y=−7x+3:

y=−7x+3

y=(−7)(−3)+3

y=24(Simplify both sides of the equation)

Answers

Answer:

Step-by-step explanation:

We know the formula for area (for triangles) is: 1/2bh.

We can write the equation 10=1/2(4)(h). 1/2*4 = 2, so 10=2h. Divide 2 from both sides, and we get 5.

What is the value of z?

Answers

Answer: z=4
explanation: in order to find z you need to add all of the angles given together, and all triangles equal to 180 . so 8z+12^+19z+15z=180
42z+12=180
subtract 12 from 180 then your left with
42z=168
divide 42 on both sides
and you get 168/42 = 4
z=4

Alina is an ecologist who studies the change in the bear population of Siberia over time.
The relationship between the elapsed time, t, in years, since Alina began studying the population, and the total
number of bears, N(t), is modeled by the following function:
t
N(t) = 2187 - (0.67)
Complete the following sentence about the yearly percent change of the bear population.
Every year,
% of bears are
added to / subtracted from
the bear population in Siberia.

Answers

Answer:

Subtracted from 33

Step-by-step explanation:

Every year, the bear population shrinks  by a factor of  2/3.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The exponential model is: N(t)=2187.(2/3)t

Let's analyze that function.

When t = 0, (2/3)⁰ = 1 and N(0) = 2,187 × 1 = 2,187

Thus, the population of bears starts with 2,187 individuals.

For t = 1, the population will be N(1) = 2,187 × (2/3).

For t = 2, the population will be N(2) = 2,187 × (2/3)²

And so on, every year the population of bears is multiplied by a factor of 2/3.

Since, 2/3 is less than 1, every year the population will be decreasing (decaying), by a factor of 2/3.

Thus, the answer, i.e. the complete sentence, is:

Every year, the bear population shrinks  by a factor of  2/3.

Hence, Every year, the bear population shrinks  by a factor of  2/3.

Answers

Answer: $37

Step-by-step explanation:
The remaining balance, B (in dollars), on the card after buying x prints is given as $50.00 - 0.15x.


Therefore, the remaining balance on the card if Jane bought 20 prints will be:
= $50.00 - 0.15x.
= $50.00 - 0.15(20)
= $50.00 - $3.00

To rent a certain meeting room, a college charges a reservation fee of $16 and an additional fee of $6 per hour. The chemistry club wants to spend less than $82 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?
