What is the measure of

Step-by-step explanation:

20−5y+2x

20-5(-2)+2(5)

20+10+10=40

Answer:

20 − ( 5 ) ( −2 ) + ( 2 ) ( 5 )

= 20 − ( −10 ) + ( 2 ) ( 5 )

= 30 + ( 2 ) ( 5 )

= 30 + 10

= 40

Answer:

  11.8

Step-by-step explanation:

The number has no digits to the right of the tenths place, so the number is correctly rounded as is.

  11.8

Answer:

I believe it should be 5.882%

Step-by-step explanation:

This is how i got tought to do it

85-80=5

5/85=0.05882

0.05882 times 100=5.882%

and that's your answer hope you get it right.

Answer:

Quadrant III

Explanation:

The positives-negatives value rule in quadrants:

Quadrant I = ( + , + )

Quadrant II = ( - , + )

Quadrant III = ( - , - )

Quadrant IV = ( + , - )

Answer:

0.484 g

Step-by-step explanation:

N/No = (1/2)^t/t1/2

No = mass of cesium-137 originally present

N= mass of cesium-137 at time t

t1/2= half life of cesium-137

t = time taken

N/5.5=(1/2)^105/30

N/5.5=(1/2)^3.5

N/5.5= 0.088

N = 5.5 *  0.088

N= 0.484 g

Answer:

Step-by-step explanation:

The general steps are ...

It is generally convenient to put the variable terms on the side of the equation having the largest (most positive) variable term. You do the rearranging by subtracting the terms you don't want. Any operation is performed on both sides of the equation.

__

1) 3x + 7 = 4x

We observe the largest x-term is on the right, and the only constant term is on the left. We can subtract the x-term 3x to eliminate it from the left side

  3x +7 -3x = 4x -3x

Combining like terms gives ...

  7 = x . . . . . this is the solution

__

2) x +2 +2x = x + 10

We observe x-terms and constants on both sides of the equation. First of all, we will combine like terms.

  3x +2 = x +10

The largest x-term is on the left, so we choose to subtract x (the x-term on the right)

  3x -x +2 = x -x +10

  2x +2 = 10

We don't want the constant on the left, so we subtract 2.

  2x +2 -2 = 10 -2

  2x = 8 . . . . . . . . . . combine like terms

Now, we divide by the coefficient of x.

  2x/2 = 8/2

  x = 4 . . . . . . the solution

__

3) x +3x = x + x + 10

  4x = 2x +10 . . . . . . . combine like terms

  2x = 10 . . . . . . . . . . . subtract 2x

  x = 5 . . . . . . . . . . . . . divide by 2

__

4) 2x +3 + 3x = x + 11

  5x +3 = x +11 . . . . . . . . combine like terms

  4x +3 = 11 . . . . . . . . . . . subtract x

  4x = 8 . . . . . . . . . . . . . . subtract 3

  x = 2 . . . . . . . . . . . . . . .divide by 4

_____

Learn to identify and combine like terms. Use addition or subtraction to eliminate terms you don't want. Use multiplication or division to eliminate coefficients you don't want. Whatever you do to one side of the equation must also be done to the other side of the equation. (In the above, we use "subtract ..." to mean "subtract ... from both sides of the equation," for example.)

Answer:

x > 25

Step-by-step explanation:

3(2x−8)>4x+26

Step 1: Simplify both sides of the inequality.

6x−24>4x+26

Step 2: Subtract 4x from both sides.

6x−24−4x>4x+26−4x

2x−24>26

Step 3: Add 24 to both sides.

2x−24+24>26+24

2x>50

Step 4: Divide both sides by 2.

Answer: 60 is the answer.

Step-by-step explanation: We can use the total sum, 180.

To get the missing angle, add the 2 angles, 60 and 60.

60 + 60 = 120.

Then subtract from 180.

180 - 120 = 60.

Hence, 60 is the answer.

Let me know if you have any questions.

~ Lily, from Brainly.

Note to asker: Write this down!

To find 1 missing angle:

A1 + A2 = TA - 180 = X (A1 = Angle1)

If 74% are in the display, then 100% - 74% = 26% are hung on the wall.

This means 104 cars is 26% of her collection.

To find the total collection divide the number on the wall by the percentage of the collection:

104/0.26 = 400

The total number of her collection is 400 cars.

Answer:

3.25 days

Step-by-step explanation:

Irri is traveling in a group of 8 cat warriors. Each cat needs 4 liters of milk per day to maintain good morale.

The total number of liters for the cat is calculated as:

8 × 4 liters of milk

= 32 liters of milk.

Another cat has enough milk to last for 2days.

= 4 liters of milk × 2 days

= 8 liters

Mirri has a supply of 96 liters of milk.

Total liters of milk = 96 liters + 8 liters

= 104 liters

Which equation can we use to find the total number of days the milk will last?

This is calculated as:

= 104 liters/32 liters

= 3.25 days
