You first divide 40 by 19:

19/40=?

Then you convert that to percentage by dropping the decimal point and attaching a %

(hint: you should get 48% about :)

Answer:

47.5%  is 19 of the 40 .

Step-by-step explanation:

As given

19 is a part value of 40.

Let us assume that the x % is 19 of the number 40.

Now written x % in the decimal form.

= \frac{x}{100}

Than the equation becomes

\frac{x\times 40}{100} = 19

Solving the above

\frac{19\times 100}{40} = x

\frac{1900}{40} = x

x = 47.5%

Therefore  47.5%  is 19 of the 40 .

Answer:

You would at least a 90 to average out your score to an 84

but I dont know how to get the inequality sorry

I hoped this helped a little

Step-by-step explanation:

Fisrt you will need to find the average of the numbers by adding them up and dividing by 3 ( because there are 3 numbers )

which would give you 81

then you have to get at least above an 81 to make it go higher but you may have to do a little more than that there for 90 is what you need

Evaluate. [(12−5)⋅12]÷6
snow_lady [41]
So first you would use the PEMDAS method. You would begin by subtacting 12 and 5 which is 7 then you would 7 multiply by 12 which is 84. Lastly you would divide it by 6 which would leave you with your final answer 14

Diego is solving the inequality 100 − 3x ≥ -50. He solves the equation 100 − 3x = -50 and gets x = 50. What is the solution to t
ZanzabumX [31]

Answer:

x≤50

Step-by-step explanation:

100-3x≥-50

subtracting 100 at both side on inequality

-100+100-3x≥--50-100

-3x≥-150

Dividing both sides by 3

-3x/3≥-150/3

-x≥--50

Adding 50 on both sides

-x+50≥-50+50

-x+50≥0

Adding x on both sides

-x+x+50≥0+x

50≥x

so,

x≤50
