Do you multiply when you have an x right after a math number like this: 3x+4x= What would it equal?

Mathematics

Answer:

3x+4x=7x

Step-by-step explanation:

basically 3x+4x means 3*x+4*x

thus, we can take x out as a common factor of both

x(3+4)= x*7=7x

or

you can sum the variables with the same element (x is our element in here)

thus,

3x+4x=7x

if it would be 3x+4y you cannot sum them since the elements are different (x and y)

What is the value of the expression? ( 5/2 ) ^2 +3/4 ^3
NeX [460]

5/2 ^2 =  6 1/4 = 6.25

3/4^3 =  27/64 = 0.4201875

6 1/4 + 27/64 = 6 43/64  (mixed number)

6.25 +0.421875 = 6.671875 (decimal)


 not sure what format you need, since the question was in fraction form, I think you need to answer using a mixed number though.

105 + 35m = expression . Apply the distributive property and the greatest common factor to write an equivalent
andrey2020 [161]

Answer:

<h2>35 × (3 + m)</h2>

Step-by-step explanation:

The distributive property:

<em>a × (b + c) = a × b + a × c</em>

105 = 35 × 3

35m = 35 × m

105 + 35m = 35 × 3 + 35 × m = 35 × (3 + m)

Jeff and his family are driving to visit his grandmother.they have driven about 30 miles, which is about 2/3 of the way. ow much
finlep [7]
Say you have 3 cakes. How many cakes would you have eaten if you ate 1/3 of the three cakes? One, you have eaten one cake, out of the three you have.

How many cakes do you have left if you eat 2/3 of the three cakes? Two, you have eaten 2 cakes, and have 1 cake left.

It is a similar approach here, except the confusing part is working "forward", when you really have to work "backward". If you have driven 30 miles, and you have driven 2 parts out of the trip when there is 3 parts of the trip, how many miles have you driven? Hint: Dividing 30 by 2 gives you what fraction of the distance to Jeff's grandmother?

What are the coordinates of the point that is one half the distance between A(-1, -2) and B(6, 12)?
MA_775_DIABLO [31]

The coordinates of the point that is one-half the distance between A(-1,-2) and B(6,12) is (2.5,5)

What is the midpoint?

The mid-point lies midway between the two ends. Its x value lies in the middle of the other two x values. Its y value lies in the middle of the other two y values.

Given, A(6,12) = (x_{1}, y_{1} )

           B(6,12) = (x_{2}, y_{2} )

Let M is a midpoint of AB, then

M(x,y)=(\frac{x_{1}+x_{2}  }{2} ,\frac{y_{1} +y_{2}}{2} )= (\frac{-1+6}{2} ,\frac{-2+12}{2} )=(2.5,5)

The midpoint of point AB is M(2.5,5)

Therefore, the coordinates of the point which is one-half the distance between A(-1,-2) and B(6,12) is M(2.5,5).
