For what values of "x" is the inequality 3(x+2)-x<8 true?
x > 1
x < 1
x < 7
x > 7
We can't determine right off the bat what values of x make this inequality true, so we should solve it first.
First, use the distributive property and distribute 3 :
3(x+2)-x<8
3x+6-x<8
Now subtract 6 on both sides :
3x-x<8-6
3x-x<2
now , subtract the x's :
2x<2
Divide by 2 on both sides :
x<1
So the values of x less than 1 make this inequality true.Let's try -1 (-1 is less than 1)
Plug it in ↓
3(-1+2)-(-1)<8
3(1)+1<8
3+1<8
4<8
4 is less than 8.
Therefore, the values of x that make this inequality true are indeed less than 1.hope helpful ~
Answer:
x < 1
Step-by-step explanation:
Expand the brackets: 3 * x = 3x and 3 * 2 = 6
Current inequality: 3x + 6 - x < 8
Collect like x terms: 3x - x = 2x
Current inequality: 2x + 6 < 8
Collect like integer terms: subract 6 from both sides
Current inequality: 2x < 2
Convert 2x to x: divide both sides by 2
Final answer = x < 1

The function P(x)=2x+1 is dilated by the function I(x)=1/2P(x). Which function rule represents I(x)?
We will see that we can write the function I(x) as:
I(x) = x + 1/2.
How to get the function I(x)?
We know that I(x) is a vertical dilation of scale factor 1/2 of P(x), where:
P(x) = 2x + 1.
The vertical dilation will be written as:
I(x) = (1/2)*P(x).
If we replace P(x) by the actual function, we will get:
I(x) = (1/2)*(2x + 1) = x + 1/2.
Then we can conclude that the function I(x) is:
I(x) = x + 1/2.

For a 12-month period, the numbers of inches of snow per month in Chicago
were:
11, 10, 6, 1,0,0,0,0,0, 1, 2, 9
What is the range of the data values?
O A. 6.
B. 1
C. 11

Step-by-step explanation:
Calculating range is subtracting the highest data value(11) from the lowest data value(0)
11 - 0 = 11
An altitude is drawn from the vertex of an isosceles triangle, forming a right angle
and two congruent triangles. As a result, the altitude cuts the base into two equal
segments. The length of the altitude is 18 inches, and the length of the base is
17
inches. Find the triangle's perimeter. Round to the nearest tenth of an inch.
Answer:56.8 inches
Step-by-step explanation:
For perimeter we must find the lengths of the 2 diagonal sides of the triangle which are the same because it is isosceles.
the triangle is cut directly in half so both halves of the base are 17/2
17/2 = 8.5
solve through pythagoren theorum
altitude^2 + (half of base)^2 = (diagonal length)^2
18^2 + (8.5)^2 = (diagonal length)^2
324 + 72.25 = (diagonal length)^2
396.3 = (diagonal length)^2
[tex]\sqrt{396.3}[/tex] = diagonal length
diagonal length = 19.9
diagonal length + diagonal length + base = perimeter
19.9 + 19.9 + 17 = perimeter
56.8 inches = perimeter
Find the value of x. 5x° 65°
Answer:
B. 23
Step-by-step explanation:
Total = 180° for a supplementary angle.
5x + 65 = 180
5x = 180 - 65
5x = 115
x = 115/5
x = 23
Answer:
B. 23
Step-by-step explanation:
The sum of the angles that creates a straight line is 180 degrees. So we can write the equation
5x + 65 = 180
Solve for x by first subtracting 65 on both sides
5x = 115
Then divide both sides by 5
x=23
Solve the equation. -2=6/7p
HURRY!
Answer:
[tex]\boxed{\sf{p=-\dfrac{3}{7}=-0.42 }}[/tex]Step-by-step explanation:
Isolate the term of p from one side of the equation.
-2=6/7pFirst, multiply by 7p from both sides.
-2*7p=6/7p*7p
Solve.
-14p=6
Then, you divide by -14 from both sides,
-14p/-14=6/-14
Solve.
p=-3/7
Dividing is another option.
-3/7=-0.42
Therefore, the correct answer is p=-3/7=-0.42.I hope this helps you! Let me know if my answer is wrong or not.

A high school basketball coach was searching through records and found that the average height of high school basketball players is 73 inches with a standard deviation of 2.1 inches. The distribution of heights is an approximately normal distribution.
a. The typical basketball team usually has around 16 players. Describe the sampling distribution for samples of size n = 16.
b. Is it surprising to find a random sample of size n = 4 to have an average height over 75 inches? Give appropriate statistical evidence
c. Suppose the population described in the problem was clearly NOT normal. Could the question in part (b) still be answered? Explain why it could still be answered. If not, explain why.
Answer:
The heights of basketball players have an approximate normal distribution with mean, μ = 79 inches and a standard deviation, σ = 3.89 inches.

Evaluate -2x^2-4x+3 when x=-2
Answer:
3
Step-by-step explanation:
A polynomial is sometimes easier to evaluate if it is first written in Horner form:

For x = -2, this is ...
(-2(-2) -4)(-2) +3 = 0(-2) +3 = 3
The value is 3 when x = -2.

5.52 = 2.4 x 1 x d
multiply l and w, which is 2.4 x 1
5.52 = 2.4 x d
divide 5.52 by 2.4
2.3 = d
Answer: 2.12
Step-by-step explanation: Okay, you first add 2.4+1, which is obviously 3.4.
Then you subtract 5.52 by 3.4.
You should get 2.12.

A child runs 200 meters in 40 seconds. Calculate the average speed of the child in m/s
Please explain this to me step by step. Thanks!
Answer:
Step-by-step explanation:
14) Amount in Harper's school lunch account = $ 75
Cos of one meal = $ 3.25
Cost of 'm' meals = 3.25 * m = 3.25m
Balance amount in Harper's account after getting 'm' meals = $ 19.75
Total amount - Cost of 'm' meals = 19.75
75 - 3.25m = 19.75
To find the value of 'm', isolate m. To isolare m subtract 75 from both sides
-3.25m = 19.75 - 75
-3.25m = -55.25
Now divide both sides by (-3.25)
m = -55.25/(-3.25)
m = 17
15) Starting height = 24 ft
Height after t seconds = 4.5*t = 4.5t
To see the river, the drone should reach the height atleast 330 ft above the ground. ⇒ It should be at the height greater than or equal to 330 ft
Initial height + height after 't' seconds ≥ 330
24 + 4.5t ≥ 330
Subtract 24 from both sides
4.5t ≥ 330 - 24
4.5t ≥ 306
Divide both sides by 4.5
t ≥ 306/4.5
t ≥ 68
He will be able to see the river from 68 seconds ( 1 minute 8 seconds) and above.
No, Imani will not be able to the river after the drone has been raising for one minute. At 1 minute 8 seconds Imani will start seeing the river. So at one minute, the drone will not have reached the required height .

Rachel had a total of 854 local and foreign stamps. 3/7 of the stamps were foreign stamps. After her father gave her more foreign stamps, the fraction of the stamps that were foreign stamps became 2/3. How many foreign stamps did Rachel’s father give her?
Answer:
27 other stamps
Step-by-step explanation:
if you take the 88 percent and turn it into a decimal you get .88 Than you multiply .88 times the 225 stamps and that gives you 198 stamps. But that is not the answer because that is the number for foreign stamps and its asking how many other stamps are there. so you would do 225-198 stamps and get the left over 27 stamps!
