42 divided by (14-6)

Answer:

  use your compass to copy the length to a new line

Step-by-step explanation:

To make a line segment that has the same length as another, set your compass width to the length of the one you want to copy, and use that to mark the length on the line where you want your copy.

Use a straightedge to draw a line longer than JK.

AD is congruent to JK.

Answer:

Step-by-step explanation:

In a tent, there are nine boys.

There were five tents.

5 tents containing 9 boys can equal 45 boys.

(5 x 9 = 45)

In a cabin, there are seven boys.

There were four cabins.

4 cabins containing 7 boys can equal 28 boys.

(4 x 7 = 28)

Now, to find all the boys, add the numbers together.

28 boys with 45 boys will equal 73 boys.

Please check my answer for no one, not even me is right.

Good luck :)

Answer: 130°

Step-by-step explanation:

supplementary angle: ∠A+∠B=180°

x+(2x+30)=180

x+2x+30=180

   3x+30=180

          3x=150

            x=50

2(50)+30=100+30=130°

Hope this helps!! :)

Answer:

3500

Step-by-step explanation:

53 is closer to 50 and 73 is closer to 70, so 50*70 is 3500, which is the closer bet.

Answer:

Percent error = 2%

Step-by-step explanation:

Given:

Expected value = 250

Actual value = 255

Find:

Percent error

Computation:

Percent error = [(Actual value - Expected value)/Expected value]100

Percent error = [(255 -250) / 250]100

Percent error = 2%

Answer:

Its 6% because |E−T||T|×100

=(250−235)|235|×100

=15235×100

=0.0638298×100

=6.38298%

=6.38298%error

Answer:

p =√(y+4)/3

Step-by-step explanation:

y=3p^2-4

so 3p^2=y+4

then p^2=(y+4)/3

so p =√(y+4)/3

Answer:

Step-by-step explanation:

y=3p^2-4

so 3p^2=y+4

then p^2=(y+4)/3

so p =√(y+4)/3

Answer:

96 minutes.

Step-by-step explanation:

17 miles = 204 minutes

1 mile = ?

204/17 = 12 minutes

1 mile = 12 minutes

8 miles = ?

8 × 12 = 96 minutes

It would take Liset 96 minutes to run 8 miles.

Complete question is;

Sarah is expanding her landscaping business. She currently has three regions in which she provides landscaping services, and intends to increase that by two regions every month. Each region begins with eight clients, and she intends to increase the number of clients by three every month.

The estimate for the total number of clients is given by the expression below, where x is the number of months after Sarah begins the expansion.

6x² + 25x + 24

Use the information given to determine how best to complete the following sentences.

The constant of the expression represents the:

A.) increase in number of regions each month

B.) number of clients before the expansion

C.) maximum number of clients

D.) increase in the number of clients each month

The binomial (8 + 3x) is a factor of the expression, which represents the

A.) number of clients per region

B.) total number of clients

C.) total number of regions

per .

Answer:

A) Option B - number of clients before the expansion.

B) Option A - number of clients per region

Step-by-step explanation:

A) We are told that each region begins with eight clients, therefore it is a constant. Since she tends to increase this number by additional 3 each month, it means that this constant represents the number of clients before the expansion.

B) The binomial (8 + 3x) represents the new number of clients per region since each region begins with eight clients, and that she tends to increase this number by additional 3 each month.

Answer:

m+p/2=n

Step-by-step explanation:

You can't get any other multiplication factor, so the only way is to isolate n, by adding p to m and dividing by 2

Answer:

Below

Step-by-step explanation:

● Make sure you write the polynomials correctly. Pay attention to the + and - signs.

● Combine like terms: variables with variables and constants with constants

● Combine the variables with the same power. For example 2x^2 with 5x^2

● write the terms left after combining

Answer:

20480x^18

Step-by-step explanation:

first of all, solve 5(x^3)^2

(x^3)^2 means 3x2=6, so x^6. 5 times x^6 = 5x^6

(16x^4)^-3 = 1/4096x^-12

when theres a negative in exponent, make it 1/y.

when negative exponent appears in 1/y just flip it again to make it y. So...

5x^6 ( 4096x^12) = 20480x^18

Answer:

The rational numbers are a dense subset of the real numbers because every real number either is a rational number or has a rational number arbitrarily close to it.

Answer:

Informally, for every point in X, the point is either in A or arbitrarily "close" to a member of A — for instance, the rational numbers are a dense subset of the real numbers because every real number either is a rational number or has a rational number arbitrarily close to it (see Diophantine approximation).

1.999396

Step-by-step explanation:

square root of 1.999396=1.414

Hey there! I'm happy to help!

A prime number is a number whose only factors are one and itself. 5 is a prime number because the only whole numbers you can multiply to get 5 are 1 and 5.

Prime factorization is finding the prime numbers that multiply to make that number.

To do this, you see what numbers it divides by. 15 is divisible by 1, giving us 15. It is not divisible by 2, but it is divisible by 3, which gives us 5.

Now, we see if 3 and 5 can be factorized even more, but they cannot as they are both prime numbers. Therefore, the prime factorization of 15 is 3,5.

Have a wonderful day! :D

Answer:

first term a1 is -40.

Step-by-step explanation:

in an arithmetic series,

sum of first term terms (S10) = -20

Common difference (d) = 4

first term (a)= ?

number of terms (n)= 10

now,

S10 =( n÷2) [a1 +(n-1) d]

or, -20 = (10÷2) [a1 + (10-1) 4]

or, -20 = 5 ( a1 + 36)

or, -4 = a1 + 36

or, a1 = -40

[tex]\blue\star[/tex]s10 = -20

[tex]\blue\star[/tex]n = 10

[tex]\blue\star[/tex] an = -20

[tex] \green\star[/tex] solution

[tex] \green\star[/tex]s10 = n\2 [a+(n-1)d]

[tex] \green\star[/tex]-20 = 10a2[a+(10-1)4]

[tex] \green\star[/tex]-4 = a +36

[tex] \green\star[/tex]a1 = -40

[tex]\small\boxed{a = -40}[/tex]

Answer:

12

Step-by-step explanation:

M is in the middle between S and T we know 2x+6 has to be the same as 3x+3 if 3x is one more x then 2x then we do 6-3 that eqauls 3 so X=3 and 2*3=6 and 6+6= 12.

Hey there! :D

Answer:

[tex]\huge\boxed{SM = 12}[/tex]

SM = 2x + 6

MT = 3x + 3

M is the midpoint of SM

Write an expression to represent the length of ST:

ST = SM + MT

ST = 2x + 6 + 3x + 3

Combine like terms:

ST = 5x + 9

Since ST = 2(SM), set up another equation:

5x + 9 = 2(2x + 6)

5x + 9 = 4x + 12

Isolate the "x" variable:

5x - 4x = 12 - 9

x = 3.

Substitute in this value of "x" into the equation for SM:

2(3) + 6 = 12.

Answer: Cada chico recibira 5.25

Answer:

9 cups

Step-by-step explanation:

1 quart= 4 cups

4 quart= ? cups  (crisscross)

4 quart=16 cups

16-7= 9 cups

Answer:

(14, 9 )

Step-by-step explanation:

Given

[tex]\frac{x}{7}[/tex] + [tex]\frac{y}{3}[/tex] = 5 ( multiply through by 21 to clear the fractions )

3x + 7y = 105 → (1)

[tex]\frac{x}{2}[/tex] - [tex]\frac{y}{9}[/tex] = 6 ( multiply through by 18 to clear the fractions )

9x - 2y = 108 → (2)

Multiplying (1) by - 3 and adding to (2) eliminates the term in x

- 9x - 21y = - 315 → (3)

Add (2) and (3) term by term to eliminate x

- 23y = - 207 ( divide both sides by - 23 )

y = 9

Substitute y = 9 into either of the 2 equations and evaluate for x

Substituting into (1)

3x + 7(9) = 105

3x + 63 = 105 ( subtract 63 from both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Solution is (14, 9 )

Step-by-step explanation:

-3a + 20 = 3a + 20

-6a + 20 = 20

-6a = 0

a = 0

Answer: a=0

Step-by-step explanation:

Given

3a-6a+20=8a+24-5a-4

Combine like terms on both sides

-3a+20=3a+20

Subtract 3a on both sides (subtractive property of equality)

-6a+20=20

subtract 20 on both sides (subtractive property of equality)

-6a=0

Divide -6 on both sides (division property of equality)

a=0
