X+17>36 how would I solve this
Answer:
x > 19
Step-by-step explanation:
Hey there!
To solve this equation, you would solve it like any other equation.
Imagine that the inequality sign isn't there, and it's replaced with an equal sign. (I'm still going to use >, I just want you to pretend)
Solve:
x + 17 > 36Subtract 17 from both sides
x > 36 - 17x > 19That's it! there's your solution!

Answer:
30m/sec
Step-by-step explanation:
v=s/t
given s= 10m
t=1/3 sec
v= 10/(1/3)=10×3/1= 30 m/s
Answer:
10 meters per 1/3 second equals
30 meters per second and multiplying this by 60 makes it
900 meters per minute or .9 kilometers per minute
multiplying this by 60 makes it
54 kilometers per hour

The crossword style worksheet has problems that provide a simplified answer for the puzzle. See more ideas about high school math, middle school math, ...LMNP is a rectangle. Find the value of x and the length of each diagonal.
LN= 4x + 3 and MP = 8x -9
X=
Solution:
We know that:
Given diagonals: LN and MPLN and MP must be equal because they are diagonals of LMNP.LN = 4x + 3MP = 8x - 9Since LN and MP must be equation, equation formed: 4x + 3 = 8x - 9
Let's simplify the equation to find x.
Subtracting 4x both sides.
[tex]4x + 3 = 8x - 9[/tex]=> [tex]4x - 4x + 3 = 8x - 9 - 4x[/tex]=> [tex]3 = 4x - 9[/tex]Add 9 both sides.
=> [tex]3 = 4x - 9[/tex]=> [tex]3 + 9 = 4x - 9 + 9[/tex]=> [tex]12 = 4x[/tex]Divide 4 both sides.
=> [tex]12 = 4x[/tex]=> [tex]\frac{12}{4} = \frac{4x}{4}[/tex]=> [tex]x = 3[/tex]Now, let's find the length of each diagonal.
[tex]LN = 4x + 3 = 4(3) + 3 = 12 + 3 = 15 \space\ units[/tex][tex]MP = 8x - 9 = 8(3) - 9 = 24 - 9 = 15 \space\ units[/tex]Diagonals are equal
[tex]\\ \rm\Rrightarrow 4x+3=8x-9[/tex]
[tex]\\ \rm\Rrightarrow -4x=-12[/tex]
[tex]\\ \rm\Rrightarrow x=-12/-4[/tex]
[tex]\\ \rm\Rrightarrow x=3[/tex]

You take music lessons that cost $45 a month plus an additional amount for lessons during the month. If you spent $325 in music lessons in one month, how much did you spend on lessons? Select the equation and the solution (2 answer choices).
Group of answer choices
45 + n = 325
45n = 325
$280
$7.22
Answer:
45 + n = 325
n = $280
Step-by-step explanation:
total cost = monthly cost plus the cost of lessons
total cost = $325
monthly cost = $45
number of lessons = 'n'
45 + n = 325
n = 280
The essential difference between an experiment and an observational study is that:
a. Observational studies may have confounded variables, but experiments never do.
b. In an experiment, people must give their informed consent before being allowed to participate.
c. Observational studies are always biased.
d. Observational studies cannot have response variables.
e. An experiment imposes treatments on the subjects, but an observational study does not.
Answer: e. An experiment imposes treatments on the subjects, but an observational study does not.
Step-by-step explanation:
Experiment is scientific procedure that is undertaken by an individual or a researcher in order for the person to either make a discovery, or test a hypothesis.
Observational studies are the studies whereby the researchers just observe the impact of a treatment or risk factor e.g. cohort studies. In observational study, the researchers just collect data based on what they've either heard or seen and they've no control over such variables collected whole for an experiment, treatments are applied to a group and the effects are recorded.

Mary works at the Elementary School, but has to go to the airport to pick up her father. Her father works at City Hall. She drops her father at City Hall and then returns to the Elementary School. How far did Mary travel if she took the shortest route?
A. 32 miles
B. 36 miles
C. 64 miles
D. 96 miles
Answer:
D. 96 miles
Step-by-step explanation:
So, first, to get to the airport, we can take the shortest route, which is Elementary School to City Hall (21), then to High School (12), then to Airport (15).
This adds up to 48 miles.
Then, we go back to City Hall, through the High School, which is 27 miles (15+12)
Then, we go to the Elementary School from City Hall, which is 21 miles.
Add up all the miles and you get:
48 + 27 +21 = 96
6th grade math I mark as brainliest
Answer: 21 units
Step-by-step explanation: Since the y-coordinates are the same, you need to find only the difference in the x-values.
Since one is positive and one is negative, (on different sides of the y-axis) you add the distances of each coordinate from there.
Or, remember that finding the difference between two numbers is a subtraction equation, and subtracting a negative is the same as adding a positive.

Step-by-step explanation:
- 2p + 8 = 6 - (7p + 7)
Answer:
p=1
Step-by-step explanation:
first you need to get rid of the parenthesis
-2p+8=6-7p+7
then combine everything you can on their respective sides
-2p+8=13-7p
then get the variable on one side and for this, it can be done 2 different ways but both ways get the same answer
-2p+8=13-7p
+7p +7p
5p+8=13
or
-2p+8=13-7p
+2p +2p
8=13-5p
then, depending on which way you decide to solve it, you would then solve for x like you would in any regualar equation
first way shown above:
5p+8=13
-8 -8
5p=5
divide them both by 5 and p=1
or the other way shown above
8=13-5p
-13 -13
-5=-5p
divide both sides by -5 and then p=1

you start at (2, 4). You move down 4 units and up 4 units. Where do you end?
Answer:
(2, 4)
Step-by-step explanation:
the same spot because 2 - 4 = -2, and the back up -2 + 4 = 2. we do not move left or right so there is no need to change the y value of 4
Answer:
(2, 4)
Step-by-step explanation:
We are given the points (2, 4) and we are told to move down four units, and then up 4 units. Since it's up and down not left and right it's telling us that we are moving the point on the y axis, which is the four, now all we have to do is subtract four units, and then add four more units on the y axis.
4 - 4 + 4 = 4
Leaving the points unchanged, your answer is "(2, 4)."
Hope this helps.
