2/10 = 1/5 = 0.2 = 20%

Answer:

2/10 are shaded, this therefore means that if u times it by 10 it will give you the percentage, so 10x10 is 100 and 2x10=20 so it is 20/100 so the percentage is 20% as all percentages are out of 100%. The fraction is 2/10 which can be simplified down to 1/5 if u divide it by 2. The decimal is 0.2 because you divide when u divide 2 by 10 it gives u 0.2

Percentage = 20%

Fraction = 2/10 or 1/5

Decimal = 0.2

Find the range of the function

Zina [86]

Answer:

Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).

Find the domain of g(y), and this will be the range of f(x).

If you can't seem to solve for x, then try graphing the function to find the range.

If the numerator and denominator of the fraction is increased by 2an1 respectively; it becomes3/4 if the numerator and the denom

ipn [44]

Answer:

The fraction is $\frac{7}{1}$

Step-by-step explanation:

Let the numerator be x and denominator be y

So, Fraction = $\frac{x}{y}$

Now we are given that numerator and denominator of the fraction is increased by 2 and 1 respectively. it becomes 3/4

So, Fraction becomes : $\frac{x+2}{y+1}=\frac{3}{4}$

$4(x+2)=3(y+1)$

$4x+8=3y+3$

$4x-3y+5=0$ ----1

We are also given that the numerator and the denominator are decreased by 2 and 1 respectively , it becomes 1/2

So, Fraction becomes : $\frac{x-2}{y-1}=\frac{1}{2}$

$2(x-2)=y-1$

$2x-4=y-1$

$2x-y-3=0$ ---- 2

Substitute the value of y from 2 in 1

$4x-3(2x-3)+5=0$

$4x-6x+9+5=0$

$14=2x$

$7=x$

Substitute the value of x in 2

$2(2)-y-3=0$

$4-3=y$

$1=y$

So, Fraction = $\frac{x}{y}=\frac{7}{1}$

Hence The fraction is $\frac{7}{1}$

Andre tried to solve the equation 1/4(x + 12) = 2. What was his mistake? *

Umnica [9.8K]

Answer:

x=-4

Step-by-step explanation:

x+12=8

x=8-12

Andre did not multiple both by four to get the exact whole number. He also, didnt subtract 12 which is not possible due to it being multiplied by 1/4.
