Answer:

6

Step-by-step explanation:

You can do this algebraically:

Step 1: Write the unknown number as x

<em>The directions say subtract four from the number, and is equal to 2, so</em>

x - 4 = 2

Step 2: Add four to both sides

x = 6

Answer:

-2 - (-4) = 2

Step-by-step explanation:

? - (-4) = 2

The double negative makes a positive. So in reality, you're adding a positive.

? + 4 = 2

In this step, many can just guess the number just by looking at the equation, but here's the long way:

? + 4 = 2

Subtract 4 from both sides

? = 2 - 4

and the answer is ...

-2 = 2 - 4

or <u>-2 - (-4) = 2</u>

Evaluate 10 m + n 2 4 10m+ 4 n 2 ​ 10, m, plus, start fraction, n, squared, divided by, 4, end fraction when m = 5 m=5m, equals,
Bond [772]

Answer:

\therefore10m+\frac{n^2}4 =54

Step-by-step explanation:

Variables : The value of a quantity which can be changed.

Monomial : Monomial contains only one term.

Example 3x, 4,6y² etc.

Binomial: Binomial contains two terms.

Example 3+4y, 20+7z etc

Trinomial: Trinomial contains 3 terms.

Example 5x-2y+5, 7z-3y+4x etc.

Given that,

10m+\frac{n^2}4  [ It is a binomial.]

Putting m =5 and n=4

= (10\times 5)+\frac{4^2}4

=50+\frac{4\times4}{4}

=50+4

=54

\therefore10m+\frac{n^2}4 =54

A farmer planted 3 types of trees on 22 acres of land. He planted 48 trees per acre. What is the total of trees the farmer plant
antoniya [11.8K]
Hey there! :D

He planted 48 trees per acre. Ignore the '3 types of trees' part. I think the question is trying to confuse you. Multiply 48 by 22.

48*22= 1056

The farmer has planted 1056 trees.

I hope this helps!

Is the relationship shown by the data linear? x -9, -5, -1, 3 y -2,-7,-12, -17
Temka [501]
                x               y
            ------           -----
              -9              -2
             -5               -7
             -1              -12
              3               -17

ur x's all have a difference of 4, and ur y's all have a difference of -5...so yes, this is linear with a slope of (-7+2) / (-5 + 9) = -5/4
