Solve the equation 3(x+2)=5x-2

Answers

Answer 1

Answer:       3(x + 2) = 5x - 2
3(x) + 3(2) = 5x - 2
      3x + 6 = 5x - 2
   - 3x    - 3x
      6 = 2x - 2
   + 2 + 2
      8 = 2x
      2    2
      4 = x

Answer 2

Answer: $3(x+2)=5x-2\n3x+6=5x-2\n5x-3x=6+2\n2x=8\nx=4$

The probability that a new spark plug is defective is 0.06. You need two new spark plugs. What is the probability that both spark plugs you buy are defective?A) 0.06
B) 0.12
C) 0.0036
D) 0.0030

Answers

Answer:

Option C - 0.0036

Step-by-step explanation:

Given : The probability that a new spark plug is defective is 0.06. You need two new spark plugs.

To find : What is the probability that both spark plugs you buy are defective?

Solution :

Probability of one spark plug being defective is 0.06

We have to find for two defective spark plugs.

This situation is a compound event in which there is more than one possible outcome.

So, The Probability of two spark plug being defective is

$P=0.06* 0.06$

$P=0.0036$

Therefore, The Probability of two spark plug being defective is 0.0036.

So, Option C is correct.

Find the distance between r(-1, 1) and s(-4, -5) to the nearest tenth

Answers

6.7 units. You have to use the distance formula here, which is √(x1-x2)^2 + (y1-y2)^2. √(-1-(-4))^2 + (1-(-5))^2 -> √(-3)^2 + (6)^2 -> √9 + 36 -> √45 -> 6.7

Pwease help fast this is mah last question!The area of the trapezium ABCD as shown in the figure (in square units) is
A) 222
B) 111
C) 224
D) 116

Answers

Answer:

A = 222 units^2

Step-by-step explanation:

To find the area of this trapezoid, first draw an imaginary horizontal line parallel to AD and connecting C with AB (Call this point E). Below this line we have the triangle CEB with hypotenuse 13 units and vertical side (21 - 16) units, or 5 units. Then the width of the entire figure shown can be obtainied using the Pythagorean Theorem:

(5 units)^2 + CE^2 = (13 units)^2, or 25 + CE^2 = 169. Solving this for CE, we get |CE| = 12.

The area of this trapezoid is

A = (average vertical length)(width), which here is:

(21 + 16) units

A = --------------------- * (12 units), which simplifies to:

A = (37/2 units)(12 units) = A = 37*6 units = A = 222 units^2
