Step-by-step explanation:
4-2x+8/3 = 6x+15/2
12-2x+8/3= 6x+15/2 ( taken LCM. of 1,3,3 in LHS)
20-2x/3=6x+15/2
Do cross multiplication
2(20-2x) = 3(6x+15)
40-4x=18x+45
-4x-18x=45+40
-22x= 85
-x= 85/22
x= - 3.86..

Answer:
I believe its c
Step-by-step explanation:
just for reference I can't guarantee
The best described compass tool is a metal instrument with two legs-one with a point and one for a pencil option (c) a metal instrument with two legs-one with a point and one for a pencil.
What is a magnetic field?The magnetic field is defined as the field the magnetic materials generate or when an electric charge moves in a field region that generates the magnetic field.
It is given that:
A tool is a compass tool which is an indicating the north direction.
As we know,
The magnetic field is defined as the field the magnetic materials generate.
A metal object with two legs, one for a pencil and one with a tip.
Thus, the best describes compass tool is a metal instrument with two legs-one with a point and one for a pencil option (c) a metal instrument with two legs-one with a point and one for a pencil.

Question: 7 = x + 2x - 5 - 5x
Please include your steps and make sure it is accurate! Brainiest for correct answer/good answer!
Answer:
please mark me brainliest
Step-by-step explanation:
7=3x-5-5x
7=3x-5x-5
7=-2x-5
7+5=-2x
12=-2x
x=12/-2
×=-6
Answer:
-6 = x
Step-by-step explanation:
7 = x + 2x - 5 - 5x
~Combine like terms
7 = -2x - 5
~Add 5 to both sides
12 = -2x
~Divide -2 to both sides
-6 = x

So the answer is H
Step-by-step explanation:
They could be situated as
x y z
in which case xy 5 and yz = 3
The total would be 8.
if they are situated like this
x z y
then xy = 5 and yz = 3 but its going the opposite way.

Rotate ΔCAR if C(-1,-4), A(2,3), R(-3,-2) 180° about the origin
Answer:
C(1,4) , A(-2,-3), R (3,2)
Step-by-step explanation:
the formula thing for rotating 180° about the origin is (x,y) -> (-x,-y)
this doesn't mean make the number negative, but make it the opposite if that makes sense
e.g. F(2,-4) -> F(-2,4)

The data set and some summary statistics are listed.
11.5, 12.3, 13.5, 15.6, 16.7, 17.2, 18.4, 19, 19.5, 21.5
Mean: 16.52
Median: 16.95
Standard Deviation: 3.11
IQR:5.5
How does adding 5 to each of the values in the data set impact the measures of variability?
Answer:
see below:
Step-by-step explanation:
the median will become a larger, different number. The mean will also become a larger number, since it will still be dividing by the same amount of numbers in the equation, only the quantity will become larger. Same with standard deviation. The IQR will change, because the amount of the two numbers you'll be subtracting will end up greater than before.

5) What is the result of subtracting (x2 + 3x)from the polynomial (-2x2 + 4x + 5)?
Answer:
- 3x² + x + 5
Step-by-step explanation:
- 2x² + 4x + 5 - (x² + 3x) ← distribute by - 1
= - 2x² + 4x + 5 - x² - 3x ← collect like terms
= - 3x² + x + 5
Hi
Golden rule to know by heart : you can only add or substract element of the same kind.
so X^2 with X^2 , X with X , numbers with numbers...
exemple : 2X^2 +3X^2 = 5X^2
but 5X^2 -3X remains that way as 5X^2 is a " X^2" and " 3X" is a " X" so I can't substract two elements of different kind.
Now you have to translate what is ask of you into a calculus.
so : you have
A ) ( 2x^2+4x +5) - ( x^2+3x)
Math is a sport of the mind. You will only progress and become stronger if you train.
So I let you have a shot. beware of signs rules. If you still have trouble, ask in comment section..

Evaluate the function rule for the given value.
f(x)= 3× for x= -4
A. –12
B. 1/81
C. –64
D. 1/243
Answer:
B. 1/81
Step-by-step explanation:
f(-4) = 3(-4)
f(-4) = -12
Hope that helps.
-12,1/243,-64 or 1/81
1/81 would be the correct answer to the equation hope this helps
evaluate the function rule for the given value.
f(x)=3^x for x=-4
-----
f(-4) = 3^(-4)

the ground line is 12 cm and width is 10 cm find out the area of the ground and parameter of the ground
Answer:
2(x+6) + 2(x) =40
2x +12+2x=40
4x+12=40
4x=28
x=7
Now to find area it is LxW
7x13=91
So the area of the rectangle is 91 meters squared
Step-by-step explanation:
Answer:
Area=120[tex]cm^{2}[/tex]
Perimeter =44[tex]cm^{2}[/tex]
Step-by-step explanation:
area=length(l)*width(w)
=12*10
=120[tex]cm^{2}[/tex]
perimeter=2(length+width)
=2(12+10)
=2*22
=44[tex]cm^{2}[/tex]

Help me with number 23 plsssssss
The Answer is:
p=15
5x3=15
So that must mean 15/5=3
Hi! I'm happy to help!
To make this equation easier, we can use the inverse operation, multiplication (instead of division).
p÷5=3
3×5=p
Doing this will give you the same answer, it just makes it easier. 3 times 5 is 15, so p=15
We can double check our answer by putting in 15 for p.
p÷5=3
15÷5=3, this is true, so our answer is correct.
I hope this was helpful, keep learning! :D

[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]
I assume the following equation is the question you asked.
[tex] \rightarrow \sf \: 2(x - 1)(x + 2)[/tex]
If yes, these are the following are the steps to reach your answer :-
[tex]\sf \: 2(x - 1)(x + 2)[/tex]
Use the distributive property to multiply 2 by x - 1.
[tex] \sf \: \left(2x-2\right)\left(x+2\right) [/tex]
Apply the distributive property by multiplying each term of 2x - 2 by each term of x + 2.
[tex] \sf \: 2x^{2}+4x-2x-4 [/tex]
Combine 4x and - 2x to get 2x.
[tex] \boxed{ \bf \: 2x^{2}+2x-4 }[/tex]
=> The answer will be 2x² + 2x - 4.
