Answer:

13y = 52

Step-by-step explanation:

6x - 6x + 4y + 9y = (46 + 6)

6x - 6x + 4y + 9y = 52

0 + 4y + 9y = 52

0 + 13y = 52

13y = 52

(p.s. y = 4)

Answer:

23ft approx

Step-by-step explanation:

Given data

Distance from tree= 10ft

Length of ladder= 25ft

We can find the height of the tree by applying the Pythagoras theorem

z^2= x^2+y^2

z= The height of the ladder

x= The distance from the tree

y= The height of the tree

25^2= 10^2+ y^2

625=100+y^2

625-100=y^2

525=y^2

y= √525

y= 22.91

Hence the height of the tree is 23ft approx

Answer:

x = 9.85 units

Step-by-step explanation:

sin 38° = x/16

cross-multiply to get:

x = 16·sin 38° which equals 9.85

Answer:

Step-by-step explanation:

Answer: 4

Step-by-step explanation: The number 4 is being repeated the most out of the other numbers.

1. Subtract 2 from both sides of the equation

4x + 2 = 7x - 13

4x + 2 - 2 = 7x - 13 - 2

2. Simplify

4x + 2 - 2 = 7x - 13 - 2 -----> 4x = 7x - 13 - 2 -----> 4x = 7x - 15

3. Subtract 7x from both sides of the equation

4x = 7x - 15

4x - 7x = 7x - 15 - 7x

4. Simplify

4x - 7x = 7x - 15 - 7x -----> -3x = 7x - 15 - 7x -----> -3x = -15

5. Divide both sides of the equation by the same term

-3x = -15

-3x/-3 = -15/-3

6. Simplify

-3x/-3 = -15/-3

x = -15/-3

x = 5

7. Solution

x = 5

Hope that helps! :D

Given:

The inequality is:

[tex]-4x-7y<15[/tex]

To find:

The whether (-6,3) is a solution of given inequality of not.

Solution:

We have,

[tex]-4x-7y<15[/tex]

We need to check the inequality for point (-6,3).

Substitute [tex]x=-6, y=3[/tex] in the given inequality.

[tex]-4(-6)-7(3)<15[/tex]

[tex]24-21<15[/tex]

[tex]3<15[/tex]

This statement is true. It means the point (-6,3) satisfies the given inequality.

Therefore, the correct option is A. Yes, the ordered pair is a solution.

Answer:

Slope: -1/3

y intercept: (0, -2)

Answer:

Step-by-step explanation:

let original price of an article be x

marked price(price after discount )=Rs 7500

discount%=25%

discount =discount % of cost price

=25/100*x

=25x/100

=x/4

Mark price=original price-discount amount

Rs 7500=x-x/4

Rs 7500=4*x-x/4

Rs 7500*4=4x-x

Rs 30000=3x

Rs 30000/3=x

Rs10000=x

therefore original price of an article is Rs 10000.

Substitution is the  reason that the best supports statement 6 in the given proof

Two or more expressions with an Equal sign is called as Equation.

Given that ∠A=∠B, ∠A= 55 and ∠B=5x+10

We need to prove x=9

The given statements and reasons are given as below

∠A≅∠B (By given)

∠A=∠B (Congruency)

m∠A=55 (By given)

55=m∠B (Substitution)

m∠B=5x+10 (Given)

55=5x+10(Substitution)

45=5x

x=9 (Division property of equality)

Hence, substitution is the  reason that the best supports statement 6 in the given proof

Step-by-step explanation:

y=mx+b

m = slope

b = y intercept

m = 5

b = -8

y=5x-8

Answer: y = 5x - 8

Step-by-step explanation:

y = mx + b

m is the slope

b is the y-intercept

M is 5 and B is -8

So, y = 5x - 8

Answer:

288 square inches

Step-by-step explanation:

since we are not told what to find, we can as well find the volume of the prism

Volume of the prism = BH

B is the base area = 1/2 * 6 * 8

B = 48/2

B = 24 square inches

H is the height of the prism = 12in

Volume of the prism = 24 * 12

Volume of the prism = 288 square inches

Area = ( lengths )^2

676 = ( lengths )^2

lengths = √676

lengths = 26 cm

Answer:

840 soles

Step-by-step explanation:

Sea la cantidad de dinero que Mateo tenía al principio = x

Mateo compró un artefacto gastando 3/7 de su dinero, dejándole 360 ​​soles,

Por eso,

3/7 × x = 360 soles

3x / 7 = 360 soles

Multiplicar cruzada

3x = 7 × 360 soles

x = 7 × 360 soles / 3

x = 840 soles

Por tanto, el dinero que tenía Mateo al principio es de 840 soles
