If B is the midpoint of AC and AB = 4x + 14 and BC = x + 20, determine how long AC is.

Serhud [2]

Answer:

44 units

Step-by-step explanation:

Since B is the mid-point of AC

AB=BC

or,4x+14=x+20

or, 4x-x=20-14

or 3x=6

or,x=6/3=2

AC=AB+BC

= 4x+14+x+20

= 4(2) + 14 +2 +20

= 8+14+22

=44 units

Rewrite <img src="https://tex.z-dn.net/?f=%5Cfrac%7B200x%20-%20300%7D%7Bx%7D" id="TexFormula1" title="\frac{200x - 300}{x}" alt=

lord [1]

Answer:

We can rewrite this as $\frac{200x}{x} + \frac{-300}{x}$ .

$\frac{200x}{x}$ simplifies to 200 after eliminating x from the numerator and denominator and $\frac{-300}{x}$ becomes $-\frac{300}{x}$ so the final answer is $200 - \frac{300}{x}$ .

For each problem below put the lettered measures in order for greatest to the least

Len [333]

Angles can be used to estimate the side lengths of a shape.

The letters in order of greatest to least are (a), (b) and (c)

The sum of angles at side (a) is:

$a = 30 + 50$

$a = 80$

The sum of angles at side (c) is:

$c = 50 + 90$

$c = 140$

The sum of angles at side (b) is:

$b = 40 + 90$

$b = 130$

So, we have:

$a = 80$

$b = 130$

$c = 140$

The smaller the base angles, the longer the side.

Hence, the letters in order of greatest to least are (a), (b) and (c)
