what is the answer for 23/4 + -23/4 - -15/4 + 9/4

Answers

Answer 1

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 2

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!)

Evaluate each expression for the given values of m and n. 2m - 4n(3m – 4) if m= 1 and n= -3 (2)​

Answers

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

Find three consecutive even integers such that five times the second is six more than twice the sum
of the first and third integers

Answers

Answer:

The first number = 4The second number = 6The third number = 8

Step-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

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)

Answers

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
