Find the number if: 4.5% of it is 23% of 45

Usimov [2.4K]

Well, let's say the number is "x", so "x" is the 100%.

now, what the dickens is 23% of 45 anyway?

if we take 45 to be the 100%, what is its 23%?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
45&100\\
a&23
\end{array}\implies \cfrac{45}{a}=\cfrac{100}{23}\implies \cfrac{45\cdot 23}{100}=a\implies 10.35=a$

ok, well, we know then that 4.5% of "x" is 10.35, we also know that "x" is the 100%, what is "x" anyway?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
x&100\\
10.35&4.5
\end{array}\implies \cfrac{x}{10.35}=\cfrac{100}{4.5}\implies x=\cfrac{10.35\cdot 100}{4.5}$

X/6+1=3 what is x please help

belka [17]

Answer:

X = 12

Step-by-step explanation:

First you subtract 1. That gives you:

x/6 = 2.

Then you multiply by 6 to cancel out the denominator under the x. That gives you:

x = 12.

That is the value of X.

Find the value of x in the figure below.<br><br><br><br> Please help me, Thank you!!

kirill115 [55]

I can answer this, but it is all based on assuming that both parts of that line are equal, so if you know otherwise then please don't use this answer.
3x + 5 = 5x - 7
- 3x
5 = 2x - 7
+ 7
12 = 2x
÷ 2
6 = x
So you get x as 6, I hope this helps!
