Answer:

36/5

Step-by-step explanation:

First, we need to isolate the x.

7+x/3=2x-5

x/3=2x-12

x=6x-36

-5x=-36

x=36/5

Hoped this helped!

Answer:

Step-by-step explanation:

7+X/3 = 2x - 5

7 + x = 3( 2x - 5) [ cross multiplication]

7 + X = 6x - 15

Move variable to LHS and change its sign

X - 6x + 7 = -15

Move constant to R.H.S and change its sign

X - 6x = -15 - 7

Collect like terms

-5x = -15 - 7

Calculate the difference

-5x = -22

The difference sign(-) will be cancelled in both sides

5x = 22

divide both sides of the equation by 5

5x/5 = 22/5

calculate

X = 22/5

Hope this helps..

Good luck on your assignment...

The width of a rectangle is the length minus 3 units. The area of the rectangle is 10

sergeinik [125]

Answer:

w=2

Step-by-step explanation:

A=length times width (A=lw)

w= l-3

A=10

Substituting in, we get:

10= l(l-3)

Now, solve the equation.

10= $l^{2}$ -3l

$l^{2}$ -3l-10=0

(l+2) (l-5)=0 (factoring the equation)

Therefore, l= -2 or 5

Throw out the negative value because a length of rectangle will never be negative.

Now let's solve for width

Remember w=l-3

therefore

(5)-3=2

so, w=2

(honestly, this is easier to just do in your head. But here is the long form math if you happen to run into more complicated problems.)

How to found the volume

never [62]

The formula to find the volume is 1/2(l*w*h)
Height= 7.6
Width=9
Length=13
So, 1/2(7.6*9*13) and you will get the answer

Multiply 3i(−1 + 2i). What is the simplified version written in standard form, a + bi, where a and b are real numbers?

Sholpan [36]

3i (- 1 + 2i) Remove the brackets.
3i (-1) + (2i)(3i) Look at the first set of brackets around the -1
-3i + 6i^2 But i^2 = - 1[ I hope that's the way you are using it]
-3i - 6 or -6 - 3i or -3(2 - i) <<<<< answer
