If x = -12, then solve:
-X =
(Please help me need answer by 1pm)
Answer:
-x = 12
Step-by-step explanation:
x = -12
if you multiply both sides of the equation by -1, you get
-1x = -12 * -1
-x = 12
Answer:
12
Step-by-step explanation:
So what we know is that x is equal to negative 12. To make this easier you can say that -x is the same as -1 times x like shown below,
-1 × [tex]x[/tex] is the same as -X
We can replace the x with -12 and a negative times a negative is a positive so the answer would be 12.
If you want me to explain it more let me know, but hopefully this helps and have a great day!

The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.27°F and a standard
deviation of 0.54°F. Using the empirical rule, find each approximate percentage below.
a. What is the approximate percentage of healthy adults with body temperatures within 1 standard deviation of the mean, or
between 97.73 °F and 98.81°F?
Answer: follow this you'll be able to solve it
Step-by-step explanation: mean = 98.11F
standard deviation = 0.56F
99.79 – 98.11 = 1.68 = 3 standard deviations
96.43 – 98.11 = –1.68 = –3 standard deviations
96.43F and 99.79F are 3 standard deviations from the mean 98.11F.
By the empirical rule we know that 99.7% of the data lies within 3 standard deviation of the mean.
Approximately 68% of healthy adults in this group have body temperatures within 1 standard of the mean, or between 97.55F and 98.67F.

Solve for x.
√10x−29=x−2
Enter your answers in the boxes.
Answer:
x = 11, 3
Step-by-step explanation:
√(10x - 29) = x - 2
(√(10x - 29))² = (x - 2)²
10x - 29 = x² - 4x + 4
-10x + 29 -10x + 29
x² - 14x + 33
(x - 11) (x - 3)
x - 11 = 0; x - 3 = 0
+ 11 +11 +3 +3
x = 11 x = 3

Find the measure of the missing angels.
Answer:
'b' and 'c' = 119 degrees
Step-by-step explanation:
Given that this is a basic intersection of straight lines, we can assume 'b' and 'c' are equal as well as the given angle and it's opposite. Given 61 degrees and and two straight lines we can just take 180 degrees - 61 degrees and we get 119 degrees, I solved for 'b', but this will give the same answer for 'c', as 'b' and 'c' are equal.
Answer:
B = 119°
C = 119°
Step-by-step explanation:
The value of back to back angles are the same when the lines are straight.Therefor there are two 61° they add together to make 122°You can then subtract 122 from 360 to get 238.Then take 238 and divide it by 2, to get your answer which is 119° for both.is -7 a solution to the equation 8(1/4x+3/4)-3+17?

Given that r = 9.2 m and = 17", work out AB rounded to 3 SF
Answer:
2.813 m
Step-by-step explanation:
x = 9.2 θ = 17 AB=?
Looking at our angle we have an adjacent side & need to find the opposite side.
So tan θ = opp/adj
tan 17 = AB/9.2
AB = 9.2tan17
AB = 2.813 m
Which of the following are factor pairs for 72? You will select two.
2 x 36

6 x 12
8 x 8
Answer:
The two factor pairs for 72 are the following:
2 × 366 × 12Step-by-step explanation:
Of you take the answer to each equation only these two equal 72, leaving them as factors.
3 × 18 is equal to 54
8 × 8 is equal to 65

Do these ratios form a proportion?
$30 per 46 pounds
$15 per 23 pounds
Answer: Yes!
Step-by-step explanation:
a proportion is when to ratios are equivalent to each other and that they are set equal to each other
If you see, $30 is divided by 2 to get $15. Same goes for the pounds, 46 is divided by 2 to get 23. They follow the same proportion
Hello can someone please answer this question i will mark you the Brainliest
Answer:
A) 310 cm²
Step-by-step explanation:
The surface area is the area of the two-dimensional surfaces of this three-dimensional figure.
Start by multiplying each 5x4 rectangle. There are four of them that are visible from the front.
4(5 · 4) 4(20) = 80 cm²Now, find the surface area of the large rectangle in the back and the left side of the figure.
2(10 · 4) = 80 cm²Find the surface area of the top of this figure.
10 · 5 = 50 cm²5 · 5 = 25 cm²Find the surface area of the bottom of this figure (it's the same as the area of the top).
50 + 25 = 75 cm²Add all of the surface areas together to find the total surface area of the figure.
80 + 80 + 75 + 75 = 310 cm²help please
find the value
Answer:
t = 9 cm
Step-by-step explanation:
Use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs and c is the hypotenuse of a right triangle)
Given:
a = 12b = tc = 15a² + b² = c²⇒ 12² + t² = 15²
⇒ 144 + t² = 225
⇒ t² = 225 - 144
⇒ t² = 81
⇒ t = √81
⇒ t = ±9
⇒ t = 9 only as length is always positive
Solution:
Pythagoras theorem can only be used in:
Right trianglesScalene right trianglesIsosceles right triangles.Since this is a scalene right triangle, we can use Pythagoras theorem to solve the missing length of the triangle.
=> The formula for Pythagoras theorem is a² + b² = c².Finding a, b, and c:
Let "a" be 12 cm and "b" be "t" cm."c" is the largest side of the triangle. This means that "c" is 15 cm, as it is the largest side of the triangle.Setting up the equation:
a² + b² = c²=> 12² + t² = 15²Simplifying the squares:
=> (12)(12) + t² = (15)(15)Subtracting (12)(12) both sides:
=> t² = -(12)(12) + (15)(15)=> t² = -144 + 225=> t² = 81Taking a square root both sides:
=> √t² = √81=> t = ±9Since the length cannot be negative, the value of t must be positive.
The final answer is...
t = 9Suppose a jar contains 9 red marbles and 15 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same time, find the probability that both are red.
Answer:
[tex] \frac{3}{23} [/tex]
Step-by-step explanation:
Since we start with 24 marbles, 9 of which are red, the probability of selecting a red marble is 9/24. The red marble is not put back, so there are now 23 marbles, 8 of which are red. It follows that the probability of selecting a second red marble is 8/23. So the probability of selecting a red marble and then another red marble is
[tex] \frac{9}{24} \times \frac{8}{23} = \frac{3}{8} \times \frac{8}{23} = \frac{3}{23} [/tex]
