Short answer: 100
I assume you want to find x.
We want an equation that says that x is equal to 105cm, minus that 5 percent, because that is his height before the 5% was added. That looks like:
x + 0.05x = 105
(0.05 is 5% in decimal form, which is necessary in equations like this).
x + 0.05x = 1.05x
1.05x = 105.
Isolate x by dividing both sides by 1.05
1.05x / 1.05 = x, 105 / 1.05 = 100
x = 100, so he was 100cm tall before summer
My original answer was 99.75. This is wrong because I used the 5% of 105, which is wrong because in the question it says his original height (which is x) had 5% added to it. So its 5% of x, not 5% of 105. This changes the whole equation.
Exceseuor if im wrong sorry
The total area of the pentagon should be 144 inches!!!
I know you were trouble when u walked in by Taylor swift? Right
Answer:
Please see attached image.
Step-by-step explanation:
The best way to find the location of the number line for this point is to use ticks every 1/4 (instead of the standard one unit). See how the number line is subdivided marking ticks every 1/4 (one fourth) of the unit instead of a whole unit in the attached image. That way it is easy to move exactly 5 one fourths to the left of the origin (zero) and place a "dot" in that location (this process is marked with orange arrows in the attached image)
