Answer these questions.<br> 45% of 40 is 18% of what number?
Furkat [3]

Answer:

45% of 40 is 18% of <em>100</em>

Step-by-step explanation:

Let 45% of 40 = 18% of <em>x</em> .

Taking LHS (Left Hand Side):

45% of 40

\Rightarrow \dfrac{45}{100} \times 40\\\Rightarrow \dfrac{1800}{100}\\\Rightarrow 18 ...... (1)

Taking RHS(Right Hand Side):

18% of x

\Rightarrow \dfrac{18}{100} \times x\\\Rightarrow 0.18 \times x ...... (2)

Equating (1) and (2):

18 = 0.18 \times x\\\Rightarrow x= \dfrac{1800}{18}\\\Rightarrow x = 100

Hence, 45% of 40 is 18% of <em>100.</em>

Would appreciate some help with this question, I am struggling!
ValentinkaMS [17]
I think you would multiply 14m x 9m which is 126m and then you would multiply 2.4m and 3.8m which is 9.12m. Last you would subtract 9.12m from 126m which is 116.88m...I’m sry if this isn’t correct

PLEASE HELP
ioda

Answer:

Step-by-step explanation:

Read this is as "x is 5 units away from _____ on a number line?"  We don't have a number that x is 5 units away from, so that number is just 0.  The absolute value inequality is

| x - 0 | ≤ 5

If you were to take this expression out of the absolute value symbols and put it into an inequality statement, because it is a "less than or equal to" inequality, that makes this a conjunction, and

-5 ≤ x ≤ 5

because those numbers greater than -5 and less than 5 are all less than 5 units away from 0.
