What is X?[tex]\frac{x-2}{3} = \frac{-7}{18}[/tex]
Answer:
x = 5/6
Step-by-step explanation:
Cross multiply.
18(x - 2) = 3(-7)
Divide both sides by 3.
6(x - 2) = -7
Distribute the 6.
6x - 12 = -7
Add 12 to both sides.
6x = 5
Divide both sides by 6.
x = 5/6
Answer: x = 5/6
[tex]\dashrightarrow\:\:\sf \dfrac{x - 2}{3} = \dfrac{-7}{18} \\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf (x - 2) \times 18= -7 \times 3 \\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf 18x - 36 = -21 \\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf 18x = -21 + 36\\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf 18x = 15\\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf x = \dfrac{15}{18} \\ \\ \\ [/tex]
[tex]\dashrightarrow\:\:\sf x = \dfrac{5}{6} \\ \\ \\ [/tex]

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 9N acts on a certain object, the acceleration of the object is 3 m/s2 . If the force is changed to 6N , what will be the acceleration of the object?
Answer:
The acceleration is 2m/s^2
Step-by-step explanation:
Given
Variation: Direction Variation
Represent Force with F and Acceleration with A
When
[tex]F= 9N; A=3m/s^2[/tex]
Required
Find A when F =6N
The variation can be represented as:
[tex]F \alpha A[/tex]
Convert to an equation
[tex]F = kA[/tex]
Where
[tex]k = variation\ constant[/tex]
When
[tex]F= 9N; A=3m/s^2[/tex]
We have:
[tex]9N = k * 3m/s^2[/tex]
Solve or k
[tex]k = \frac{9N}{3m/s^2}[/tex]
[tex]k = 3kg[/tex]
When
[tex]F = 6N[/tex]
We have:
[tex]F = kA[/tex]
Substitute 6N for F and 3kg for k
[tex]6N = 3kg * A[/tex]
Solve for A
[tex]A = \frac{6N}{3kg}[/tex]
[tex]A = 2m/s^2[/tex]

Use the graph of f to estimate the local maximum and local minimum. (5 points)
A piecewise graph is shown with a line increasing to 0,-2 terminating at that point and a curve starting at 0,0 and intercepting the x axis at 0, pi, and 2pi.
a) Local maximum: (0,-2); local minimum: (0,0) and (π,0)
b) Local maximum: pi ; local minimum: three pi over two, negative 1
c) Local maximum: (0,0) and pi over two, 1 ; local minimum: (0,0) and three pi over two, negative1
d) Local maximum: (0,0) and pi over two,1 ; local minimum: three pi over two, negative1

If y < -2x + 10 which of the following are viable solutions?
Answer:
y < 12x
....................
The shaded region in the graph of y < -2x + 10 represents the viable solution ordered pairs.
What is a expression? What is a mathematical equation? What is inequality?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. An inequality is used to compare two or more mathematical expressions.
We have the following inequality -
y < -2x + 10
We can write -
y < -2x + 10
Refer to the graph of the inequality attached. The shaded region represents the viable solution ordered pairs.
Therefore, the shaded region in the graph of y < -2x + 10 represents the viable solution ordered pairs.

Suppose there is a 1.8 Farenheit drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 62.4 farenheit , what will be the temperature when the plane reaches an altitude of 8,000 ft. ?
Answer:
48° FStep-by-step explanation:
Let the altitude on the ground be 0 ft
Temperature at 8000 ft is:
62.4 - 1.8°*(8000 - 0)/1000 = 62.4 - 1.8*8 =62.4 - 14.4 =48° FAnswer:

During a Middle School basketball season, Antonio made 17 of his free throws out of 20. What percent of his free throws did he make?
I see a fraction. Don't you. Here it is 17/20. Now, let's divide 17 by 20 to get a decimal number, which is 0.85. Next, we multiply 0.85 by 100 to get the percent because that is what the question desires for us to express our answer. As a result, we get 85%, and Antonio made 85% of his free throws. By the way, I hope my response helps you.
Step-by-step explanation:
1 way is to do 17/ 20 using long division...
0. 85
20⟌1700 ( I tried my best)
- 160
100
So the answer would be 85%
Another way to do it is by bringing the denominator to 100
Since 20 is 1/5 of 100, you would have to multiply the numerator and denominator by 5
17/ 20 = 17*5/ 20*5 = 85/ 100
And you get 85%
Hope this helps!!!

Two savings accounts earn simple interest. Account A has a beginning balance of $500 and grows by $25 per year. Account B has a beginning balance of $750 and grows by $15 per year.
Answer:
After 25 years both the accounts will have the same balance.
Step-by-step explanation:
Let t years, both the account will have the same balance.
As account A has a beginning balance of $500 and grows by $25 per year.
So, the total balance of account A after t years = 500+25t
Similarly, account B has a beginning balance of $750 and grows by $15 per year.
So, the total balance of account A after t years = 750+15t
As both the accounts has the same balance, so
500+25t= 750+15t
25t-15t=750-500
10t=250
t=250/10
t=25 years
Hence, after 25 years both the accounts will have the same balance.
Nicholas wants to buy a new computer that is on sale for $899. His parents will loan him the money if he repays them. He has $225 in his savings account and plans to work as a camp counselor to earn money during the summer. If he earns $35 per day, how many days will Nicholas have to work in order to fully repay his parents?
Answer:
20 days
Step-by-step explanation:
899- 225= 674
674÷ 35= 19.257....
which you would round it up to 20 because he would have to work the extra day because you need more than less.

Which of the points shown below are on the line given by the equation Y = X +3? Check all that apply. A). Point A : (-1, 2) B). Point B : (-1, -2) C). Point C : (2, 5) D). Point D : (-3, 0) Please No jokes I really need help :))
Answer:
Point APoint CPoint DStep-by-step explanation:
The points are in the format (x , y) so given x which is the first figure, you can find y by following the formula.
Y in the point needs to satisfy the criterion of X + 3.
Point A
x = -1
y = x + 3
= -1 + 3
y = 2
Point A satisfies the equation as y from the equation is y in the point given.
Point B
x = -1
y = x + 3
= -1 + 3
y = 2
Point B does not satisfy the equation and so is not on the line.
Point C
x = 2
y = 2 + 3
y = 5
Point C satisfies the equation as y from the equation is y in the point given.
Point D
x = -3
y = -3 + 3
y = 0
Point D satisfies the equation as y from the equation is y in the point given.
