Answer:
x=-8
Step-by-step explanation:
First you should add 5x+67 and 5x+61 together which is 10x+128
Then you set that equal to 3x+72 which would be: 10x+128=3x+72
After that subtract 3x from both sides which leaves you with: 7x+128=72
Then subtract 128 from 72 which gives you: 7x=-56
Then divide by 7 which gives you x equals negative eight

This triangle is a right triangle, which means One angle measure of the triangle is 90 degrees. And the given angle is 40 degrees. The total sum of all the angles in a triangle is 180 degrees.
So if you add 40 + 90 + x = 180
You get 130 + x = 180
If you subtract 180 - 130
You get 60.

The angles of a quadrilateral are in the ratio 1:2:3:4. Find the measure of each angle
Answers
Answer:
Let us consider that the smallest angle is 'x'.
According to the given ratio, the four angles are:
x2x3x4xNow, for any quadrilateral, the sum of the all four angles should be equal to 360°.
So,
x + 2x + 3x + 4x = 360°
10x = 360°
x = 36°.
Thus, the four angles are:
x = 36° 2x = 2 × 36 = 72° 3x = 3 × 36 = 108° 4x = 4 × 36 = 144°H (n) = 3n ;find h (6)

Step-by-step explanation:
PIN stands for Personal Identification Number. Option d is correct.
What is a Personal Identification Number.?An alphanumeric or numeric string called a personal identification number (PIN) is used to verify a person's identity in a system.
Automated Teller Machines (ATM) for a bank, are the primary use cases for PINs (ATM). PINs are frequently used in place of more complex passwords to unlock mobile devices and authenticate users to applications.
Along with the development of the ATM, PINs were invented in the UK. In 1967, Barclays debuted ATMs as a convenient way for consumers to obtain cash. They also introduced ATM check deposits, which made use of codes printed on checks to help correctly account for such transactions.

Answer:
E. People once thought animals were individually create by some superior.
But the solid creation of theory of origin of species by the naturalist Charles Darwin demonstrated a different theory.
Step-by-step explanation:
Before Charles Darwin several scientists were discussing the hypothesis of a theory of evolution. But it was Darwin whom put together all the information with reliable explanation and correlation between animal specialization and environment accordyinly with time.
He spent almost five years on board the ship HMS Beagle, crossing several continents, starting with South America. From there, he returned with dozens of specimens of living species, illustrations and fossils. Those specimens helped Darwin in his discoveries which originated the book On the Origin of Species published in 1859.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second. y=-16x^2+157x+124 y=−16x 2 +157x+124
Answers
Answer:
Rocket will hit the ground in 10.55 seconds.
Step-by-step explanation:
Let be [tex]y = -16\cdot x^{2}+157\cdot x +124[/tex], where [tex]x[/tex] and [tex]y[/tex] are time after launch and the height of the rocket, measured in seconds and meters, respectively. To find the time that the rocket will hit the ground, we need to equalize height to zero and solve the resulting expression:
[tex]-16\cdot x^{2}+157\cdot x + 124 = 0[/tex]
The quadratic function can be solved analitically by Quadratic Formula, that is to say:
[tex]x = \frac{-157\pm \sqrt{157^{2}-4\cdot (-16)\cdot (124)}}{2\cdot (-16)}[/tex]
Roots of the polynomial are, respectively:
[tex]x_{1} \approx 10.55\,s[/tex], [tex]x_{2}\approx -0.74\,s[/tex]
Only first root offers to us a reasonable solution. Hence, we conclude that rocket will hit the ground in 10.55 seconds.
Derrick's Doggie Day Care charges a $12 registration fee plus $5 per hour for pet sitting. Pauline's Pooch Park charges $3 per hour plus an $18 registration fee. Which inequality can be used to find the number of hours, h, for which the cost of Derrick's Doggie Day Care is at most the cost of Pauline's Pooch Park? 12+5h≥3h+18 12 plus 5 h is greater than or equal to 3 h plus 18 5h+12>18+3h 5 h plus 12 is greater than 18 plus 3 h 12+5h<3h+18 12+5h<3h+18 12+5h≤18+3h 12 plus 5 h is less than or equal to 18 plus 3 h
Answers
Answer:
[tex]12 + 5h \leq 18 + 3h[/tex]
Step-by-step explanation:
Given
Represent Derrick's with D and Pauline's with P
For D
Registration Fee = $12
Hourly Charges = $5
For P
Registration Fee = $18
Hourly Charges = $3
Required
Represent as an inequality such that D is at most of P
First, we need to represent both as an expression:
For D
[tex]D: 12 + 5h[/tex]
For P:
[tex]P:18 + 3h[/tex]
Since D is at most of P;
This implies that:
[tex]D \leq P[/tex]
So, we have:
[tex]12 + 5h \leq 18 + 3h[/tex]

If the sum of the square of the number and 4 time the number is 21,
what is the number?
Answers
Answer:
I think there is a missing “and” there: “If the sum of the square of the number and 4 times the number is 21, what is the number?”
If so, then we have: x² + 4x = 21, or x² + 4x - 21 = 0.
This factors as (x+7)(x-3) = 0, so x = -7 or x = 3.

Step-by-step explanation:
cc HB buggy CFB
The value of "x" will be "7".
Given:
[tex]m_2 = 6x+8[/tex][tex]m_6=8x-6[/tex]When "m" is parallel, then
→ [tex]m_2=m_6[/tex]
By substituting the values, we get
→ [tex]6x+8=8x-6[/tex]
By adding "6" both sides, we get
→ [tex]6x+8+6=8x-6+6[/tex]
→ [tex]6x+14=8x[/tex]
By subtracting "6x" from both sides, we get
→ [tex]6x+14-6x=8x-6x[/tex]
→ [tex]14=2x[/tex]
[tex]x = \frac{14}{2}[/tex]

Angles B and D are corresponding angles. This means D = B since corresponding angles are congruent when we have parallel lines.
Then note how D+E = 180 as these two angles form a straight angle.
Replace D with B getting B+E = 180 (this is the substitution property).
Alternatively, you can say that G = E and B+G = 180 to lead to B+E = 180. There are many other routes to take as well.

Find x so that the distance between the points (-2,5) and (x,-7) is 13
Answers
Distance between both points = 13
We have to find value of x[tex].[/tex]
Distance between two points can be measured by using this formula :
d = √[(x₂ - x₁)² + (y₂ - y₁)²]⭆ d = √[(x₂ - x₁)² + (y₂ - y₁)²]
⭆ 13 = √[(x - (-2))² + (-7 - 5)²]
⭆ 13² = (x + 2)² + (-12)²
⭆ 169 = (x + 2)² + 144
⭆ (x + 2)² = 169 - 144
⭆ (x + 2)² = 25
⭆ x + 2 = 5
⭆ x = 5 - 2
⭆ x = 3
