Answer soon!! ThanksTranslate the following into an equation:
A number x is decreased by 45. The result is then divided by 12. Then 20 is added to this new result to give a final result of five times the difference of 32 and the number x

Answers

Answer 1
Answer:

(This is a little difficult but I've got it)

((x - 45)/12) + 20 = 5(32 - x)

(I made the equation a little more complex than I should have but that equation should still work if you were to solve for x)

Answer 2
Answer:

Hey there!!

Let's get this step by step

x is decreased by 45 = x - 45

Result is divided by 12 = ( x - 45 ) / 12

Then, 20 is added to the result

[ ( x - 45 ) / 12 ] + 20

Result =

Five times the difference of 32 and x = 5 ( 32 - x )

Hence, the equation

[ ( x - 45 ) / 12 ] + 20 = 5 ( 32 - x )

( x - 195 ) / 12 = 160 - 5x

Multiply 12 on both sides

x - 195 = 12 ( 160 - 5x )

x - 195 = 1920 - 60x

Add 60x on both sides and add 195 on both sides

61x = 2115

divide by 61 on both sides

x = 34.67

x = 34.7

Hence, the required answer is 34.7 this can be rounded to 35

Hope my answer helps!

Alex spent 25% of his money on a sports drink. Then he spent 25% of the remaining money on trail mix. He has $9 left. How much money did Alex begin with?

Answers

If Alex has spent two lots of 25%, this is equal to 50%, which means he has spent half of his money. If he has $9 left, this means that he has spent $9, meaning that he started with $18. Hope this helps :)

I need to know 35-42 please

Answers

35. an open circle means there is no equal sign, and shading to the left means less then...so inequality is : x < 6

36. a closed circle means there is an equal sign, and shading to the left means less then.... x < = 9

in short...a closed circle means there is an equal sign, an open circle means there is not. if it is shaded to the left, it is less then...if it is shaded to the right, it means it is greater then.

This is to be solved from similarity of triangles, so according to similar triangles' rules, The ratio of the length of side  DC to the length of side AC is equal to the ratio of the length of side ED to the side AB. So we can solve from the proportion, \frac { 10 }{ 25 } =\frac { 5 }{ x }
