Answer:
[tex]-\frac{6}{4}[/tex]
Step-by-step explanation:
The first 2 numbers cancel, and -15/4+9/4 is the same as 9/4 - 15/4
Please mark me as brainliest if I am correct
Answer:
6
Step-by-step explanation:
In the equation, [tex]\frac{23}{4} + -\frac{23}{4} --\frac{15}{4} + \frac{9}{4}[/tex], we can see that [tex]\frac{23}{4} + -\frac{23}{4}[/tex] cancel each other out
This leaves us with [tex]--\frac{15}{4} + \frac{9}{4}[/tex]. The negatives "negate" themselves giving us [tex]\frac{15}{4} + \frac{9}{4} = \frac{24}{4}[/tex] or [tex]6[/tex]
Hopefully (some part of) this explanation makes sense (or at least somewhat). If this doesn't make sense, please tell me and I will try to make it more understandable as soon as possible.
It would help if you marked my answer as Brainliest, if I'm correct, so I can help even more people! (I would really appreciate it!)
K is between J and M. L is
between K and M. M is
between K and N. If JN = 14, KM = 4, and JK = KL = LM, what is NL?
(do step-by-step fully pls)
Step-by-step explanation:
given,
K is between J and M, L is between K and M, M is between K and N. JN = 14, KM=4 and JK= KL= LM
NL=?
according to the question,
J-------K-------L------M--------N
We know,
KM= 4
KL+LM=4
KL+KL=4 (LM=KM)
2KL=4
KL=2
SO,
JK=KL=2 and LM=KL=2
we have ,
JN=14
JK+KM+MN= 14
2+4+MN=14
MN=8
Now,
NL=LM+MN= 2+8= 10

Can someone explain how to do solve this?
Answer:
-8r
Step-by-step explanation:
-5r - 3r
Combine like terms
Factor out r
r( -5-3)
-8r
Answer:
like bases combine under add/subtract
-5 minus 3 is -8
-8r would be the solution

Which shape fits the description below?
A three-sided figure with angle measures of 60°, 60°, and 40°.
X.
Y.
Z.
OA. Y
OB. Z
OC. X
OD. The shape is nonexistent.
Answer:
OD for a triangle to exist it must equal 180 degrees as a final and this one only equals 160
Answer:
D. The shape is nonexistent.
Step-by-step explanation:
A triangle's angles must add up to 180 degrees.
60+60+40 is 160.

If A/B and C/D
are rational expressions, then
AxC/BxD = AxD/BxC
A. True
B. False
Answer:
True
Step-by-step explanation:
If A/B and C/D are rational expression then
A/B*C/D
Or
A/B*C/D=A/C*B/D
It means that if A/B and C/D are rational expression then their product with each other will also be a rational expression.

????????????
Answer:
143 = EFD
Step-by-step explanation:
The two angles form a straight line
AFD = 180
AFD = AFE + EFD
180 = 37+ EFD
180 -37 = EFD
143 = EFD

In a rotation, pairs of corresponding points are on parallel lines?
Step-by-step explanation:
Corresponding angles are congruent if the two lines are parallel. All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs.
The figure below shows a rope that circles the Earth. The radius of the Earth is 6371 kilometers. Assuming the rope makes a perfect circle, what is the length of this rope? Give your answer in terms of pi. kilometers

2. Find the domain of the function (f/g)(x) where f (x)= x^2 – 9 and g(x)= x^2 - 4x+3
A (-infinity, infinity)
B (-infinity, 1) (1, infinity)
C (infinity, 1) (1,3) (3, infinity)
D (-infinty, -3) (-3,-1)(-1, infinity)
Answer:
I think you mean C.
Step-by-step explanation:
f(x) / g(x) = (x + 3)(x - 3)
==========
(x - 3)(x - 1)
f(x)/g(x) = (x+3) / (x - 1)

Find three consecutive even integers such that five times the second is six more than twice the sum
of the first and third integers
Answer:
The first number = 4The second number = 6The third number = 8Step-by-step explanation:
Let all unknown numbers be represented by the variable x.So;x = first number
x + 2 = second number
x + 4 = third number
placing in a form as demanded by the question.5(x + 2) = 6 + 2x + 2 ( x + 4)
5x + 10 = 6 + 2x + 2x +8
5x - 4x = 14 - 10
x = 4
Therefore;The first number (x) = 4
The second number ( x + 2) = 4 + 2 = 6
The third number (x + 4) = 4 + 4 = 8
Answer:
2x + 2x +2 + 2x +4 = 6x +6 =Sum
5 * (2x +2) = 2 * (2x + 2x +4) +6
10x + 10 = 8x + 8 + 6
2x = 4
x = 2
So the numbers are:
2x or 4
2 x + 2 = 6
2x + 4 = 8
Double-Check
5 * 2nd integer = 30
2 * (1st + 3rd integers) = 24
30 is 6 more than 24

Evaluate each expression for the given values of m and n. 2m - 4n(3m – 4) if m= 1 and n= -3 (2)
Answer: -22
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
m = 1
n = -3 (2) = -6
Given expression
2m - 4n (3m - 4)
Substitute values into the expression
=2(1) - 4(-6) (3(1) - 4)
Simplify by multiplication
=2 + 24 (3 - 4)
Simplify values in the parentheses
=2 + 24 (-1)
Simplify by multiplication
=2 - 24
Simplify by subtraction

Determine if v 49 is rational or irrational and give a reason for your answer.
The number 49 is rational
because
Step-by-step explanation:
If a number is rational, we can represent it as a fraction.
[tex] \frac{a}{b} [/tex]
Where a and b are intergers.
First, we know that
[tex] \sqrt{49} = 7[/tex]
We can represent 7 as
[tex] \frac{7}{1} ..... \frac{14}{2} .... \frac{21}{3} ..... \frac{n}{y} = 7[/tex]
Where n and y are two numbers that when divided equal 7.
So
[tex] \sqrt{49} [/tex]
is a rational number

In cashing a check for $220, Christina asked for the whole amount in $10 and $20 bills. She received a total of 13 bills, four of them being $10 bills.
O True
O False
Hi
if she recieived 13 bills and 4 are 10 $? then we have 13-4= 9 20$ bills
so 4x10 +9x20 = 40+180 = 220
So yes it's true
