Answer:

x = 4

x = 1

Step-by-step explanation:

hey there,

< When you have these kinds of problems:

[tex]\frac{2}{6} = \frac{x}{12}[/tex]

There's a really easy way to solve it. Multiply the two that are across from each other. That means 2 x 12. It couldn't be 6 x [tex]x[/tex] because this one has x in it so it won't work. So you multiply them: 2 x 12 = 24. Then you divide that number by the last number available. The last number that hasn't been used yet is "6" (we have used 2 and 12). So we divide 24/6.

24/6 = 4

x = 4 >

Answer:

The answer is below

Step-by-step explanation:

a) Let y represent the amount of time kiran slept, hence:

y = x - (1/10)x = x - 0.1x

y = 0.9x

b) Let y represent the amount of time Mia practice, hence:

y = x - (2/5)x = x - 0.4x

y = 0.6x

c) Let y represent the amount of drink kiran drank, hence:

y = x + (4/3)x = 7x / 3

y = 7x/3

d) Let y represent the money Mai spent, hence:

y = x - (1/4)x  = x - 0.25x

y = 0.75x

e) Let y represent the amount of almond kiran ate, hence:

y = x + 1.5x = 2.5x

f) Let y represent the recycling Mai collected, hence:

y = x - (3/10)x = x - 0.3x

y = 0.7x

g) Let y represent the amount of km kiran walked, hence:

y = x + (3/8)x

y = (11/8)x

h) Let y represent the amount of puzzles mai completed, hence:

y = x + (3/5)x = x + 0.6x

y = 1.6x

Answer:

$87.20

Step-by-step explanation:

The one above is incorrect, It showed up as wrong for me! The correct answer is $87.20

The sales price of the outfit is $87.2.

The correct option is (2).

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Kendra is buying an outfit that is on sale for 20% off.

The original price of the outfit is $109.

The discount,

= 20% of 109

= 20 x 109 / 100

= 21.8

The sales price,

= 109 - 21.8

= 87.2

Therefore, the price is $87.2.

Answer:

90/100 or 81.8%

Step-by-step explanation:

w = 0,1 , then your grade will be 81

It depends upon how many total points are available and what the zero was out of possible points. If you have a 90/100 and a 0/100, that gives you a 45%, which is failing. If you have 90% of 1000 points and get a 0/100, that will land you with an 81.8%.

Answer: x = 11 + y

Step-by-step explanation: Simplifying

4x + -4y = 44

Solving

4x + -4y = 44

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.

4x + -4y + 4y = 44 + 4y

Combine like terms: -4y + 4y = 0

4x + 0 = 44 + 4y

4x = 44 + 4y

Divide each side by '4'.

x = 11 + y

Simplifying

x = 11 + y

Step-by-step explanation:

Step-by-step explanation:

Hey there!

According to the question,

Let the unknown number be x (smaller) another number be y (greater) respectively.

1st condition: One number is 7 more than twice of another number.

(i.e y = 2x+7)....... (i)

2nd condition: The sum is 22.

(i.e X+y= 22)……(ii)

From equation (ii).

x+ y= 22

x= 22-y

Putting the value of X in eqaution (I)

y = 2(22-y)+ 7

y = 44 - 2y +7

3y = 44+7

y = 51/3

Therefore, y= 17.

Now, Putting the value of y in eqaution (ii)

X = 22-y

x = 22-17

Therefore, x= 5.

Therefore, one number is 17. (Option D).
