Answer:

The given equation is

4x+10=-26

We add the additive inverse of 10 which is -10 to both sides of the equation to obtain,

4x+10+-10=-26+-10

This gives us,

4x+10-10=-26-10

4x+0=-36

ANSWER TO QUESTION 1


The given equation is

4x+10=-26


We add the additive inverse of 10 which is -10 to both sides of the equation to obtain,

4x+10+-10=-26+-10


This gives us,

4x+10-10=-26-10


4x+0=-36


This further simplifies to  


4x=-36


We divide both sides 4 to obtain,

x=-4


ANSWER TO QUESTION 2


Since we got -4 as answer to question one, the next question to answer is

\frac{x}{3}+10=15


We add the additive inverse of 10 which is -10 to both sides to obtain,


\frac{x}{3}+10+-10=15+-10


This gives us,

\frac{x}{3}+10-10=15-10


This simplifies to


\frac{x}{3}+0=5


\frac{x}{3}=5


We now multiply both sides of the equation by 3 to obtain,


3\times \frac{x}{3}=5\times3

This implies that,

x=15


ANSWER TO QUESTION 3


The next equation is 9-2x=35


We add the additive inverse of 9 which is -9 to both sides of the equation to obtain,

9+-9-2x=35+-9

This gives us,

9-9-2x=35-9


This simplifies to,


-2x=26


We multiply both sides by the reciprocal or the multiplicative inverse of -2 to obtain,

-2x\times (-\frac{1}{2})=26\times(-\frac{1}{2})


This gives us,

x=-13


ANSWER TO QUESTION 4.


The next question is \frac{2}{3}x+15=17


We add the additive inverse of 15 to both sides of the equation to obtain,


\frac{2}{3}x+15+-15=17+-15


This evaluates to


\frac{2}{3}x+0=17-15


This implies that,

\frac{2}{3}x=2


We multiply both sides by the multiplicative inverse or the reciprocal of \frac{2}{3}


This implies that,


x=2\times\frac{3}{2}


x=3


ANSWER TO QUESTION 5

The next question to answer is -5x-10=10.


We add the additive inverse of -10 which is 10 to both sides of the equation to obtain,


-5x-10+10=10+10


This gives us,

-5x=20


We through by -10 to obtain,

x=-4


ANSWER TO QUESTION 6

\frac{3}{4}x-9=27


We add the additive inverse of -9 which is 9 to both sides of the equation to obtain,

\frac{3}{4}x-9+9=27+9


This simplifies to;

\frac{3}{4}x=36


We multiply both sides of the equation by the reciprocal of \frac{3}{4} to obtain,

\frac{3}{4}x \times \frac{4}{3}=36\times \frac{4}{3}


x=36\times \frac{4}{3}


x=12\times 4


x=48


ANSWER TO QUESTION 7


The next question to answer is \frac{1}{2}x+13=9.


We add the additive inverse of 13 which is -13 to both sides of the equation to obtain,


\frac{1}{2}x+13+-13=9+-13


This will evaluate to,


\frac{1}{2}x=-4


We now multiply both sides of the equation by 2 to obtain,

x=-4\times 2

x=-8


ANSWER TO QUESTION 8


The last question to solve now is \frac{x-7}{4}=-2


We first of all multiply both sides of the equation by 4 to obtain,


\frac{x-7}{4} \times 4=-2\times 4


This implies that,


x-7=-8


We now add the additive inverse of -7 which is 7 to both sides of the equation to obtain,

x-7+7=-8+7


This implies that

x=-1

Tristán wants to build a square garden in his backyard if the garden is going to be 64 ft2 how many feet of material will he nee
Alex777 [14]

Answer:

Tristan will need 32 feet of material for the perimeter of the garden.

Step-by-step explanation:

Given that

Area of square garden = A = 64 square feet

Perimeter = P = ?

We know that for calculation of perimeter, length of side of square is required which is not directly given in the question. The area will be used to calculate length of side and then length will be used to calculate the perimeter.

So,

Area = A = s^2

s is for side

Putting the value of area

64 = a^2

Taking square root on both sides

\sqrt{s^2} = \sqrt{64}\\s = 8\ feet

The length of side is 8 feet.

Perimeter will be:

P = 4*s\\P = 4*8\\P = 32\ feet

Hence,

Tristan will need 32 feet of material for the perimeter of the garden.

zhannawk [14.2K]

The probability that the Yankees will lose when they score fewer than 5 runs is 17.16%.

<h3><u>Probability </u></h3>

Given that this season, the probability that the Yankees will win a game is 0.61 and the probability that the Yankees will score 5 or more runs in a game is 0.56, and the probability that the Yankees win and score 5 or more runs is 0.44, to determine what is the probability that the Yankees will lose when they score fewer than 5 runs the following calculation must be made:

  • 1 - 0.61 = 0.39
  • 1 - 0.56 = 0.44
  • 0.39 x 0.44 = X
  • 0.1716 = X

Therefore, the probability that the Yankees will lose when they score fewer than 5 runs is 17.16%.

If M is the set of all perfect squares that are less than 100 and N is the set of all positive numbers that are less than 15. wr
deff fn [24]

The sets of M and N are { 4 , 16 , 25 , 36 , 49 , 64 , 81 } and{ 0, 1 , 2 , 3, 4, 5 , 6, 7 , 8, 9, 10, 11, 12, 13, 14, 15 }

<h3>What is set?</h3>

Set is a collection of elements or numbers or objects.

It is represented with the symbol '{}'

We have that;

  • M is the set of all perfect squares that are less than 100
  • N is the set of all positive numbers that are less than 15

M = { 4 , 16 , 25 , 36 , 49 , 64 , 81 }

N = { 0, 1 , 2 , 3, 4, 5 , 6, 7 , 8, 9, 10, 11, 12, 13, 14, 15 }

Thus, the sets of M and N are { 4 , 16 , 25 , 36 , 49 , 64 , 81 } and{ 0, 1 , 2 , 3, 4, 5 , 6, 7 , 8, 9, 10, 11, 12, 13, 14, 15 }
