If 10% of x is 30, what is 23% of x <br> A. 33<br> B. 46<br> C. 200<br> D. 230
aliina [53]

Answer:

69

Step-by-step explanation:

I'm mathematics, the word 'of' transfers into becoming 'times or Multiply'

Therefore, the expression can be rewritten as:

10/100 of x = 30

10x / 100 = 30

Cross Multiply the equation to solve for x

10x = 100 * 30

10x = 3000

x = 3000 / 10

x = 300

(Since we gotten the value of x as 300) let's find 23% of it.

Therefore,

23% of x, ( when x is 300)

= 23/100 * 300

= 23 * 3

= 69

(Well, although that's the workable solution, the option doesn't seen to tally)

Maybe you check the source, but am certain about the Solution.

Let's keep learning, maths is fun !

Two quantities, x and y, are directly proportional. If x is doubled, what happens to y?
vagabundo [1.1K]

Answer:

y is also doubled.

Step-by-step explanation:

Direct proportionality between x and y means that

y \propto x

or

y=cx,

which indicates a linear relationship between  x and y because they are related by a constant.

Therefore, if x is doubled, then the new value of y is y_{new}

y_{new}=c(2x)

y_{new}=2(cx)

y_{new}=2y

The new value of y is 2 times the previous; therefore, y is doubled as x is doubled.
