Answer:

We have to find the value of x.

We need to substitute with 3 because they measure the same.

Step-by-step explanation:

(x - 1)

x - 1 = 3

x - 1 + 1 = 3 + 1

x = 4

(x + 1)

x + 1 = 5

x + 1 - 1 = 5 - 1

x = 4

Both answers are the same which means that they are correct.

Answer:

The inequality to represent “7 less than the product of a number, n, and 1/6 is at most 45” is:

[tex]\frac{n}{6} -7\leq 45[/tex]

Solution:

Let the number be "n"

From given,

7 less than a product of a number n and 1/6 is at most 45

At most means "less than or equal to"

Therefore, inequality is framed as:

[tex]( n x \frac{1}{6}) -7 \leq 45[/tex]

Thus, inequality is:

[tex]\frac{n}{6} -7\leq 45[/tex]

 Solve the inequality:

Add 7 to both sides

[tex]\frac{n}{6} -7 + 7\leq 45 + 7\\simplify\\\frac{n}{6} \leq 52[/tex]

Multiply both sides by 6

[tex]\frac{6n}{6} \leq 52 multiply 6[/tex]

simplify

[tex]n\leq 312[/tex]

Thus the inequality is solved.

hope it help :)

Answer:

24

Step-by-step explanation:

First we need to find the area on one square which is 2*2 which is 4. So now we have 5 more cubes like this and we have to add all their areas to find the surface area so we make a multiplicaction sentence :

4*6=24

Answer:

26/x = 13

x = 2

Step-by-step explanation:

2(x - 4) = 4

2x - 8 = 4

2x = 4 + 8

2x = 12

x = 12/2

x = 6

26/x = 13

Cross product

26 = x * 13

26 = 13x

x = 26/13

x = 2

- 3.8x = -7.4

x = -7.4 / -3.8

x = 1.95

4(x - 1) - 3(x - 2) = -8

4x - 4 - 3x + 6 = -8

x + 2 = -8

x = -8 - 2

x = -10

Step-by-step explanation:

Hello There!

We are going to convert each fraction to decimal form to make it easier to tell if the statement is true or false

[tex]\frac{2}{3} =.66\\\\\frac{2}{6}=.33[/tex]

.66 is greater than .33 therefore [tex]\frac{2}{3} >\frac{2}{6}[/tex] is a true statement

[tex]\frac{8}{10} =.8\\\\\frac{6}{5} =1.2[/tex]

1.2 does not equal 8 therefore [tex]\frac{8}{10} =\frac{6}{5}[/tex] is a false statement

[tex]\frac{1}{8} =.125\\\\\frac{1}{4}=.25[/tex]

.25 is greater than .125 therefore  [tex]\frac{1}{8} <\frac{1}{4}[/tex] is a true statement

[tex]\frac{2}{4} =.5\\\\\frac{1}{2} =.5[/tex]

.5 is equal to .5 therefore [tex]\frac{2}{4} >\frac{1}{2}[/tex] is a false statement

[tex]\frac{4}{10} =.4\\\\\frac{4}{6} =.66[/tex]

.66 is greater than .4 therefore [tex]\frac{4}{10} <\frac{4}{6}[/tex] is a true statement

Answer: true false true false true sorry and just give the other person brainly and thank u

Answer:

Simplify each term.

Px+px+3p=10x−7

Move all terms not containing P to the right side of the equation.

Px=10x−7−px−3p

Divide each term by x and simplify.

P=10−7/x−p−3p/x

The awsner is -11

Answer: 5x^2+3x+1

Step-by-step explanation:

Solving for (f+g)(x) add both functions so

(3x^2+4x)+(2x^2-x+1)

Add like terms

3x^2+2x^2=5x^2

4x+-x=3x

+1

Add terms

5x^2+3x+1

Answer:

x ≈ 14.7

Step-by-step explanation:

Assuming the triangle is right then use Pythagoras' identity.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 15² = 21²

x² + 225 = 441 ( subtract 225 from both sides )

x² = 216 ( take the square root of both sides )

x = [tex]\sqrt{216}[/tex] ≈ 14.7 ( to the nearest tenth )

Answer:

X=2

Step-by-step explanation:

first combine like terms

subtract the x

add 5

lastly divide by 7

Answer:

6/10 is greater than 6/100

Answer:

90

Step-by-step explanation:

88 plus 89 plus 90 is equal to 267

Answer:

-88

Step-by-step explanation:

(-3 + 4) x 66 + -19 x 8 - 2

According to PEMDAS (or GEMDAS), you start with the parenthesis. So you do the equation in the parenthesis.

-3+4= 1

Now you replace it with your answer.

1 x 66 + -19 x 8 - 2

You next do multiplication.

1*66=66

66+ -19 x 8 -2

Multiplication again

-19*8=-152

66 + -152 - 2

Now there is only addition and subtraction left so you solve left to right.

66 + -152= -86

-86-2=-88

The answer is -88

Answer:

The probability is 0.1312

Step-by-step explanation:

Here, let us set up a binomial system

From the question, 54% ride a bike

Let p = people that rides a bike

54% = 54/100 = 0.54

p = 0.54

q = 1 - p = 1 -0.54 = 0.46 ( 46% do not ride bikes)

Now, for the binomial system, we have

P(X = 15) = 30 C 15 • p^15•q^15

We have;

30 C 15 * 0.54^15 * 0.46^15

= 0.131200268998

The probability is 0.1312

Answer:

1. 136°

2. 36°

3. 136°

4. 36°

5. 136°

6. 36°

7. 136°

8. 44°

Step-by-step explanation:

i don't know english very well so i don't knoe what transplant is but i think i got it right with my logic

Answer:

m∠1 = 136°

m∠2 = 44°

m∠3 = 136°

m∠4 = 44°

m∠5 = 136°

m∠6 = 44°

m∠7 = 136°

Step-by-step explanation:

Corresponding angles, like m∠1 and m∠5, need to equal each other.

m∠1 and m∠3 are the same

m∠3 and m∠2 need to be added together to equal 180
