n200080 [17]3 years ago
6 0

Answer:

x = 4

Step-by-step explanation:

<em>To solve, we need to isolate </em><em>x</em><em>.</em>

<em>Start by moving the </em><em>20</em><em> to the other side by subtracting it from both sides.</em>

2x = 8

<em>Since </em><em>x</em><em> is being multiplied by </em><em>2</em><em>, we need to </em><u><em>divide</em></u><em> both sides by </em><em>2</em><em> to move it to the other side.</em>

x = 4

45) lí the midpoint of AB is (4,3) and point A has coordinates (-2,6),
sweet [91]
Midpoint has a formula x plus x2 divided by 2 and vice versa for y
So to solve you need to fill in numbers
You can replace x with negative 2 since you know that the coordinates for point A are -2,4
Solve to get 10
And vice versa for the y coordinate you solve the filled in equation to get 0
Your end result is 10,0

The top of an off shore oil rig has an elevation of 199.2 m and its base has an elevation of -9.6 m and observation deck is loca
matrenka [14]

Answer: 57.6m

Step-by-step explanation:

That's a lot of words that questions usually use to try to trip us up but not this time so lets pull all relevant information

199.2m= top of off shore oil rig

-9.6 m is the base of the rig

observation deck is 1/6 of the total height

helly pad is 22.8m above the observation deck

First lets try to find the total height of the rig. We can do this by adding the absolute value of the top and base of the oil rig. So 199.2 + 9.6 = 208.8m

So the total height is 208.8m now lets find the observation deck. We know the observaition is 1/6 of the total height which is 208.8m right so lets multiply. 1/6*208.8m= 34.8m

Now we know the observation deck is 34.8m high. Finally we can find the helly pad which is 22.8 m above the observation deck.

Since the observation deck is 34.8m and the helly pad is 22.8 above observation deck (34.8m) all we have to do is add so 22.8+34.8= 57.6m

So we know the total height is 208.8m

The observation deck is 34.8m

And the helly pad is 57.6m
