Answer:
2x - 1 = -45.
Step-by-step explanation:
2x - 1 = -45 is the required equation.
x is the number.
17 + x = 26
17 +n = 26
n + 17 = 26
something like those, you didn't give options to choose from.
Solve;
If each cm = 4 meters, then you multiply.
4*2
= 8
There are 2 cm, each cm = 4 meters, so you multiply to get your answer.
The final height of the door is 8 meters.
First, you need to get the denominators (the bottom number) the same. The smallest number to get them to is 15.
So, what you need to do is take 2/5 and multiply the bottom by 3 to get 15, and since you did it to the bottom, you need to do it to the top too. So you would get, 6/15.
Then, for 1/3, take the bottom number and multiply it by 5. Then, since you did it to the bottom, do it to the top as well. You would get 5/15.
Then, you need to put them side by side. You don't add the bottom, so your denominator would remain 15, but your numerator (top) would get added.
<u> 6</u> + <u>5</u> = <u>11</u>
15 15 15
