Answer:

The answer is t.

Step-by-step explanation:

We need to find the sum of opposite of - 10t and t - 10t.

Opposite of -10t = 10 t

So,

10t + (t-10t)

Grouping the numbers,

(10t+(-10t)) + t

= 0 + t

= t

Hence, the answer is t.

Answer:

2x+2

Step-by-step explanation:

Perimeter = 2 * width + 2 * length

12x+10 = 2(4x+3) + 2 * width

12x+10 = 8x + 6 + 2w

4x+4 = 2w

2x+2 = w

Addition property of equality with -18; add -18 to both sides

4n=28

Division property of equality; divide 4 from both sides

Answer:

105

Step-by-step explanation:

all angles inside a triangle add up to equal 180, the inside angle at R is 75 degrees, the TP line is obviously a 180 degree angle, because it's just a straight line, so you subtract 75 from 180 to get 105

[tex]1\frac{1}{9}[/tex]

The correct answer is below:

Answer:

[tex]\dfrac{6x+2}5}[/tex]

Step-by-step explanation:

The given expression is :

[tex]\dfrac{3x}{5}+\dfrac{2}{5}+\dfrac{3x}{5}[/tex]

We need to write the equivalent expression for the above expression.

Taking like terms together,

[tex]=(\dfrac{3x}{5}+\dfrac{3x}{5})+\dfrac{2}{5}\\\\=\dfrac{3x+3x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x+2}5}[/tex]

So, the equivalent expression is [tex]\dfrac{6x+2}5}[/tex].

Answer:

I see you are rolling a standard fair six-sided die twice. There are 6 equally likely outcomes on each roll of the die. Die Roll #1: P(Perfect square) =1/3 The winning outcomes are 1 and 4, this makes the fraction 2/6, which reduces to 1/3.

Step-by-step explanation:

PLEASE MARK ME AS BRAINLIEST

The probabilities for the following statements are:

a) 1/4

b) 1/18

c) 1/3

d) 1/12

e) 1/6

f) 1/36

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

The sample space for rolling a die twice.

= {1, 2, 3, 4, 5, 6 } x {1, 2, 3, 4, 5, 6}

= {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6), (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6) }

The number of possible outcomes.

= 36.

Now,

The number of outcomes where both are odd.

= { (1, 1), (1, 3), (1, 5), (3, 1), (3, 3), (3, 5), (5, 1), (5, 3), (5, 5) }

The probability that both are odd.

= 9/36

= 1/4

The number of outcomes where both are a perfect square.

= {1, 1), (4, 4) }

The probability that both are perfect squares.

= 2/36

= 1/18

The number of outcomes where the first is even and the second is less than 5.

= { (2, 1), (2, 2), (2, 3), (2, 4), (4, 1), (4, 2), (4, 3), (4, 4), (6, 1), (6, 2), (6, 3), (6, 4) }

The probability that where first is even and second, is less than 5.

= 12/36

= 1/3

The number of outcomes where the first is prime and the second is 6.

= { (2, 6), (3, 6), (5, 6) }

The probability where the first is prime and the second is 6.

= 3/36

= 1/12

The number of outcomes where both are the same.

= { (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6) }

The probability that both are the same.

= 6/36

= 1/6

The number of outcomes of at least 4 both times.

= {(4, 4)}

The probability that at least 4 both times.

= 1/36

Thus,

The probabilities for each statement are given above.

Step-by-step explanation:

x=3g+2

you need to move the equation to the other side, first you'd start with the one furtherest from g, which is is 2.

x = 3g

-2. - 2

and minus it from both sides

x-2=3g

3g is like 3x, which is 3 times x and you need to use the opposite operators so times would become divide.

so now it becomes x-2 over 3=g

Answer:

the factors are:

[tex]\frac{2}{3}\times \frac{3}{5}[/tex]

Option C is correct option.

Step-by-step explanation:

The overlapping section(green colours common for both) while blue represents first factor and yellow represent second factor.

Solving:

The first part of the factor is considered horizontal rows (as shown in figure)

So, we have 3 horizontal rows and 2 rows are coloured so, the fraction will be: [tex]\frac{2}{3}[/tex]

For the second factor, we consider vertical columns (as shown in figure)

So, we have 5 columns and 3 columns are coloured so, the fraction will be: [tex]\frac{3}{5}[/tex]

So, the result will be:

[tex]\frac{2}{3}\times \frac{3}{5}=\frac{6}{15}[/tex]

So, the factors are:

[tex]\frac{2}{3}\times \frac{3}{5}[/tex]

Option C is correct option.

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

Step-by-step explanation:

Let x be the number of points the 5 girls scored.

=> 41 - x is the number of points the 2 boys scored.

We have x + 29 = 41 - x or x - 29 = 41 - x.

=> 2x = 12 or 2x = 70

=> x = 6 or x = 35

We reject x = 6 as 6 is not a multiple of 5. (Each girl would have scored 1.2 points which is absurb)

So x = 35, each girl scored 35/5 = 7 points.

=> 41 - (35) = 6, each boy scored 6/2 = 3 points.

Answer:

-95/87

Step-by-step explanation:

Formula to find slope: (y2-y1) / (x2-x1)

In this problem y2 is -3 and y1 is 92. x2 is 97 and x1 is 10.

We substitute these numbers into the equation.

(-3-92) / (97-10)

Then we simplify this by subtracting.

-95/87 is our final answer.
