Answer:

Step-by-step explanation:

E is the midpoint of Ac & D is the midpoint of AB

DE = (1/2)BC {Midpoint theorem}

$x +1 = \dfrac{1}{2}(4x - 6)\\\\\\
Multiply \ the \ whole \ equation \ by 2\\\\
2*(x+1) =2*\dfrac{1}{2}*(4x - 6)$

2*x + 2*1 = 4x - 6

2x + 2 = 4x - 6

Add 6 to both sides

2x + 2 + 6 = 4x

2x + 8 = 4x

Subtract 2x from both sides

8 = 4x - 2x

2x = 8

Divide both sides by 2

x = 8/2

x = 4

Write an equation that represents degrees fahrenheit in terms of degrees celsius. let xx represent the temperature in degrees ce

IgorC [24]

As we know Conversion from fahrenheit to celsius is
$F - 32 = \frac{9C}{5}$

We can write it also as

$F = \frac{9C}{5}+32$

F as y and C as x then we can write it as

$y = \frac{9x}{5} + 32$

I need help. how do i write 4=(-8)+3x as a decimal

Vanyuwa [196]

This is an equation, you can't write equations as decimals. I think you're asking for x (as a decimal)?

Add 8 to each side: 4+8= 8+(-8)+3x
12=3x
x=4
This is a whole number so it's already in decimal form
