x/2−5=−12
I need to know how to get the answer to what X is
Answer:
-14
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x/2-5=-12
1/2x+-5=-12
1/2x-5=-12
Step 2: Add 5 to both sides.
1/2x-5+5=-12+5
1/2x=-7
Step 3: Multiply both sides by 2.
2*(1/2x)=(2)*(-7)
x=-14
Answer:
-14
Step-by-step explanation:
x/2 = -12 + 5 << add both sides by 5
x/2 = -7 << Combine -12 + 5
x = -14 << Multiply both sides by 2
This revolves around the idea of inverse operations
To get x by itself we needed to bring the other numbers to the other side of the equation.
Inverse operations is bring the numbers to the other side by doing the opposite operation it shows.
ex: if the number is +5 on one side, it will be -5 on the other

Jada rewrites 5•3^x as 15x. Do you agree with Jada that these are equivalent expressions? Explain your reasoning. Help me pleasee
Answer:yes
Step-by-step explanation:
5*3=15
5*3x=15x
The expression 15x is not the equivalent of the expression 5•3ˣ.
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
It is a relation of the form y = aˣ in mathematics, where x is the independent variable
Jada rewrites 5•3ˣ as 15x.
We do not agree with Jada that these are equivalent expressions because she made the mistake.
As per the given obtained expression, we can see that here write 15 as the coefficient of variable x which is actually the power of an argument. the original expression was an exponential function that has 3 representing the base. thus, it cannot be multiplied the 5 by 3.
Thus, the expression 15x is not the equivalent of the expression 5•3ˣ.

Answer:
x = 65, y = 63
Step-by-step explanation:
∠ EGA = ∠ HBG = 52° ( corresponding angles )
ED is a straight angle, thus
52 + y + 65 = 180, that is
y + 117 = 180 ( subtract 117 from both sides )
y = 63
-------------------------------------
∠ HGB = y = 63° ( vertical angles )
The sum of the 3 angles in a triangle = 180°, thus
x + 63 + 52 = 180
x + 115 = 180 ( subtract 115 from both sides )
x = 65
Ratnam hired a car from a car renting agency which charges a flat amount of Rs. x for travelling up to 50 kilometres and Rs. y per km for every kilometer travelled thereafter. How much should Ratnam pay the agency for a journey of 70 kilometres?
a x + 70y
b x +20y
c 50x +20y
d 50 + 2y
Answer:
Correct option: b -> x + 20y
Step-by-step explanation:
From the first 50 kilometers, the price is a flat amount of x, and for the kilometers travelled thereafter, the price is y per kilometer.
If Ratnam travelled 70 kilometers, he needs to pay 'x' because of the first 50 kilometers, and (70 - 50) = 20 times y for the rest of the travel.
So the final price is:
x + 20y
Correct option: b
The correct option is b x + 20y
Given that,
Ratnam hired a car from a car renting agency which charges a flat amount of Rs. x for travelling up to 50 kilometres and Rs. y per km for every kilometer travelled thereafter.Based on the above information, the equation is as follows:
x + (70 - 50)y

What is the least common multiple of the two denominators?
6/8 4/32
A.18
B.12
C. 8
D.32
Answer:
d.32
Step-by-step explanation:
To get the Least Common Multiple (LCM) of 8 and 32 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:
8: 222
32: 22222
LCM: 22222
The Least Common Multiple (LCM) is: 2 x 2 x 2 x 2 x 2 = 32
The least common multiple is = 32
The denominators are 8 and 32.
The multiples of 8 are = 8, 16, 24, 32, 40, ....

The expresssion is also equivalent to the cost of the item? c-0.25 c which expression is also equivalent to the cost of the item? 1-0.25c 0.25c 0.75c 1-0.75c
Answer:
0.75c
Step-by-step explanation:
If we have an expression as:
a*x + b*x
We can see that both terms in the expression, a*x and b*x have an x, so we can call the x a common factor and we can write an equivalent expression as:
a*x + b*x = (a + b)*x
If we replace, for example, a by 2, b by 3 and x by 4, we can test the expression as:
2*4 + 3*4 = (2 + 3)*4
8 + 12 = (5)*4
20 = 20
Therefore, if we have the following expression:
c - 0.25*c
The expression that is equivalent is 0.75c and it is calculated as:
c - 0.25*c = (1 - 0.25)*c
c - 0.25*c = 0.75*c

A coin is tossed and a die is rolled. What is the probability that a tail was tossed and an even number was rolled?What is the probability that a head was tossed and a number larger than 4 was rolled?
Please Show Work! Thanks!
Answer:
First problem: 1/4 chance
Second problem: 1/6 chance of happening
Step-by-step explanation:
To find the probability we need to multiply the chance of each separate thing happening by each other in each example.
In the first example we have a 1/2 chance that a tail was tossed and 3/6 chance that an even number was rolled.
[tex]\frac{1}{2} *\frac{3}{6} = \frac{3}{12} =\frac{1}{4}[/tex]
So in the first example we have 1/4 chance of happening or 0.25
Same thing with the second example:
[tex]\frac{1}{2} *\frac{2}{6} = \frac{2}{12} =\frac{1}{6}[/tex]

Find the surface area and volume of the figure.
Answer:
Surface area: 310.86 sq ft
Step-by-step explanation:
First, find the surface area of the cylinder. This can be found by finding the area of the circle at its base, and then the area of its mid-region.
The area of the circle can be found using the formula: a = pi(r^2). r stands for radius, which is 3 in this problem. 3^2 equals 9, which, multiplied by pi (3.14), equals 28.26.
The area of the cylinder's mid-region is equal to the circumference of the circle multiplied by the height of the cylinder. The circumference of the circle is equal to c = 2pi(r), or in this case: 18.84. Now, multiply this value by the height to get 226.08 as the area of the mid-region.
Lastly, find the surface area of the sphere. This can be found using the equation a =4πr^2. r is, again, radius, which in this problem can be represented by 3. The surface area of a sphere with a radius of 3 is 113.04. However, this figure only shows half a sphere, which can be found by dividing 113.04 in half. This gets you 56.52.
Now, simply add all the areas together to get the total surface area!
In a certain city with a working population of 10,500 , 8925 people and less than $75,000 per year what is a percentile rank of someone who earns $75,000 per year
Answer:
The percentile rank of someone who earns $75,000 per year is the 85th percentile.
Step-by-step explanation:
Meaning of percentile:
When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.
In this question:
Working population of 10,500
8,925 people earn less than $75,000 per year.
8925/10500 = 0.85
0.85*100 = 85
The percentile rank of someone who earns $75,000 per year is the 85th percentile.

A jar contains 5 popsicle sticks, numbered 1-5. A stick is drawn, then a letter in the word SPRING is chosen at random. What is the probability the number is greater than 2, then P?
Answer:
10% probability that the number is greater than 2, then P
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Event A: Number greater than 2.
Event B: Letter P.
These events are independent, so:
[tex]P(A \cap B) = P(A) \times P(B)[/tex]
P(A)
There are 5 numbers.
3, 4 or 5, that is, 3 numbers greater than 2.
3/5 = 0.6. So P(A) = 0.6.
P(B)
6 letters, one of which is P. So
P(B) = 1/6 = 0.1667.
What is the probability the number is greater than 2, then P?
[tex]P(A \cap B) = P(A) \times P(B) = 0.6 \times 0.1667 = 0.1[/tex]
10% probability that the number is greater than 2, then P

Step-by-step explanation:
The "zeros" of the quadratic equation simply refers to what x equals when q(x) = 0.
Set the equation equal to zero as so: 0 = x^2 - 9, and solve!
9 = x^2
+/- 3 = x, when q(x) = 0.
This means that the two points you are trying to find are (-3, 0) and (3, 0)!
Solve for the zeros of the quadratic function f(x) = 9.2 + 6x +1. Write the answer as a fraction.
Answer:
x = -1.7, or x = -17/10
Step-by-step explanation:
f(x) = 9.2 + 6x + 1 is a linear function and as such (and because the slope is not zero) has only one solution. Combining like terms, we get
f(x) = 10.2 + 6x = 0 (you must set this equal to zero if solving for zero(s).
Then 6x = -10.2, and x = -1.7, or x = -17/10
