Answer:

x=2

Step-by-step explanation:

3(x-2)-6x=4(x-5)

Distribute

3x -6  -6x = 4x -20

Combine like terms

-3x-6 = 4x-20

Add 3x to each side

-3x-6+3x = 4x-20+3x

-6 = 7x-20

Add 20 to each side

-6+20 = 7x-20+20

14 = 7x

Divide by 7

14/7 =7x/7

Answer:

<h2>x = 2</h2>

Step-by-step explanation:

3(x - 2) - 6x = 4(x - 5)

Distribute 3 through the parentheses

3x - 6 - 6x = 4(x - 5)

Distribute 4 through the parentheses

3x - 6 - 6x = 4x - 20

Collect like terms

- 3x - 6 = 4x - 20

Move variable to L.H.S and change it's sign

- 3x - 4x - 6 =  - 20

Move constant to RHS and change it's sign

- 3x - 4x =  - 20 + 6

Collect like terms

- 7x =  - 20 + 6

Calculate

- 7x =  - 14

Divide both sides of the equation by -7

\frac{ - 7x}{ - 7}  =  \frac{ - 14}{ - 7}

Calculate

x = 2

Hope this helps..

Best regards!!

The midpoint, M , of segment AB has coordinates (2,−1) . If endpoint A of the segment has coordinates (−3,5) , what are the coor
lbvjy [14]

the coordinates of endpoint B are (7,7)

Answer:

Solution given:

M(x,y)=(2,-1)

A(x_{1},y_{1})=(-3,5)

Let

B(x_{2},y_{2})=(a,b)

now

by using mid point formula

x=\frac{x_{1}+x_{2}}{2}

$ubstituting value

2*2=-3+a

a=4+3

a=7

again

y=\frac{y_{1}+y_{2}}{2}

$ubstituting value

-1*2=5-b

b=5+2

b=7

the coordinates of endpoint B are (7,7)

7. Jena has a triangular garden with a perimeter that can be represented by 25r ^ 2 - 9r + 14 . The sum of two sides of the gard
galben [10]

Answer: 15r^2-21r+5

Step-by-step explanation:

Given: Perimeter of triangular garden = 25r^2 - 9r + 14

The sum of two sides of the garden = 10r^2 + 12r + 9

Perimeter is the sum of all sides of a triangle.

Third side = Perimeter of triangular garden - sum of two sides of the garden

=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5

The expression represent the third side = 15r^2-21r+5.

The tax rate is 3.9%<br> What is the tax on 42$? <br> Round to the nearest hundredth
mafiozo [28]
To find the total price, we use this equation:
42 + 0.039(42)
We can make it simpler:
1.039(42)
Multiply:
43.638
Because we're rounding
The total price is $43.64

What is the slope of the line?<br> 3x-4y=7
Vinvika [58]

Answer:

3/4

Step-by-step explanation:

3x - 4y = 7.....subtract 3x from both sides

-4y = -3x + 7 ...now we divide both sides by -4

(-4/-4)y = (-3/-4)x + (-7/4)...simplify

y = 3/4x - 7/4

y = mx + b

y = 3/4x - 7/4.....so the number in the m position is 3/4 <== ur slope
