Find the error for the proposed solution. Then correct the proposed solution.
2x + 18 = 16
2x = 34
2x 34
2 2
X = 17

Answers

Answer 1

Answer:

The error is in the second line.

x = -1

Step-by-step explanation:

When solving for "x", you are trying to isolate it, or move everything else to the other side. You may have learned that "what you do to one side, you do to the other" .

2x + 18 = 16

2x = 34               18 was added to the right side, but not to the other.

If you add 18 on both sides, then the equation would be:

2x + 36 = 34       "x" is not being isolated.

Instead, you should subtract 18 from 16.

Correct solutions steps:

2x + 18 = 16

2x + 18 - 18 = 16 - 18     Subtract 18 from both sides to cancel out 18

2x = -2

2x/2 = -2/2                     Divide both sides by 2

x = -1                              Final answer

Hence, second option is the true option.                            {Result of spin, card color}

{Green, Purple} {Yellow, Purple}  {Purple, Purple }

{Green, Green}  {Yellow, Green}  {Purple, Green}

Step-by-step explanation:

It is given that:

A spinner with 3 equal sectors is shown in the figure. The colors Green, Yellow, and Purple are marked on it.

Two cards are shown on the right side. Their colors are Purple and Green.

The table that identifies the sample space of spinning the spinner and then selecting  a card is:

     {Result of spin, card color}

{Green, Purple} {Yellow, Purple}  {Purple, Purple }

{Green, Green}  {Yellow, Green}  {Purple, Green}

( Since in rest of the options the red color in the sample space but there is no card or no such color in the spin which is red)

Each color on the wheel can match with each color of the cards:

Wheel has green, blue red

Cards are purple and green:

The combinations could be:

This season, the probability that the Yankees will win a game is 0.54 and the probability that the Yankees will score 5 or more runs in a game is 0.6. The probability that the Yankees win and score 5 or more runs is 0.46. What is the probability that the Yankees would score 5 or more runs when they lose the game? Round your answer to the nearest thousandth.

Answers

Answer:

O.304

Step-by-step explanation:

0.14 / 0.46

The probability that the Yankees would score 5 or more runs when they lose the game will be 0.140

What is probability?

Probability is synonymous with possibility. It is concerned with the occurrence of a random event. Probability can only have a value between 0 and 1.

The probability that the Yankees will win a game is, 0.54

The probability that the Yankees win and score 5 or more runs is 0.46

(P>5)=0.6

The probability that the Yankees would score 5 or more runs when they lose the game is found as;

P(fail and ,>5)=P(score>5)-P(win and score>5)

P(fail and ,>5)=0.6-0.46

P(fail and ,>5)=0.140

Hence,the probability that the Yankees would score 5 or more runs when they lose the game will be 0.140

Step-by-step explanation:

200-60 = 140

Answer:

c

Step-by-step explanation:

Substitute the values in the problem to get, (200) = 2(60) + 2W. Solve for W to get 200 = 120 + 2W. Subtract 120 on both sides to get 80 = 2W. Divide by 2 on both sides to get 40 = W or a width of 40 feet.

Pleaaasseee help!!! BRAINLIEST FOR CORRECT ANSWER!! What is the transformation rule for a translation 3 units right?

Answers

Answer:

Rule: replace x by x - a where a is the number of units that you want to move right. a must be greater than 0. x - - a  would move left.

Step-by-step explanation:

You want f(x) to move 3 units to the right.

That would mean that  x would be replaced by x - 3.  Just to be sure let's try it.

Suppose you have f(x) = x^2 + 6x + 5       It is graphed as the red lineNow suppose you want to move 3 units right. It would replaced like f(x - 3) = (x - 3)^2 + 6(x - 3) + 5 which is the blue lineNotice nothing else is changed. The blue line looks exactly like the red line except that it is shifted 3 units to the right.

Consider the quadratic equation 3x^2-6=2x. (a) What is the value of the discriminant? (b) What does the discriminant of the quadractic equation tell about the solutions to 3x^2-6=2x?

Answers

Answer:

(a) discriminant is positive, 76

(b) the above tells you there are two real roots

Step-by-step explanation:

the discriminant is 'b² - 4ac'

3x² - 2x - 6 = 0  ∴ a = 3, b = -2, c = -6

(-2)² - 4(3)(-6) = 4 + 72

(a) The discriminant of the quadratic equation is positive, 76.

(b) The quadratic equation tells you there are two real roots.

What is a quadratic equation?

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

The discriminant of a polynomial in mathematics is a quantity that depends on the coefficients and enables inference of some root features without computing them.

Given that the quadratic equation 3x²-6=2x.

The discriminant Of the quadratic equation is calculated by the formula below:-

D = b² - 4ac

3x² - 2x - 6 = 0  ∴

a = 3, b = -2, c = -6

Put the value of the coefficient to get the value of the discriminant.

D = (-2)² - 4(3)(-6) = 4 + 72 = 76

Therefore, the discriminant of the quadratic equation is positive, 76, and the quadratic equation tells you there are two real roots

$1.25

Step-by-step explanation:

Given: the cost of the shopping trip is $25.00

They want us to find the tax amount at 5%.

Saying that we need to find the 5% of the $25.00.

Convert 5% to 0.05, then take it times 25.

$25 x 0.05 = $1.25

That should give you the 5% of the $25.

If you add $25.00 and the $1.25 together, it should give you $26.25, included with the tax.
