Solve for y. 2y - 5 = 5y - 11

Answers

Answer:

y = 2

Step-by-step explanation:

Given equation:

[tex]2y - 5 = 5y - 11[/tex]

Subtract 5y both sides:

[tex]\implies 2y - 5 = 5y - 11[/tex]

[tex]\implies 2y - 5 - 5y = 5y - 5y - 11[/tex]

[tex]\implies -3y - 5 = -11[/tex]

Add 5 both sides:

[tex]\implies -3y - 5 = -11[/tex]

[tex]\implies -3y - 5 + 5 = -11 + 5[/tex]

[tex]\implies -3y = -6[/tex]

Multiply -1 both sides:

[tex]\implies -3y = -6[/tex]

[tex]\implies \dfrac{-3y}{-1} = \dfrac{-6}{-1}[/tex]

[tex]\implies 3y = 6[/tex]

Divide 3 both sides:

[tex]\implies 3y = 6[/tex]

[tex]\implies \dfrac{3y}{3} = \dfrac{6}{3}[/tex]

[tex]\implies \boxed{y = 2}[/tex]

5. John is tiling the living room floor of his home. The living room is a rectangular shape
room that is 10 ft. 9in, by 15ft. 3 in.

a. What is the perimeter of the room?

B. How many 6in by 6in square tiles are required to cover the floor?

C. Calculate 10% of the answer from
Part b (this accounts for the overage due to grout and waste)

Answers

B is the correct answer

The perimeter of the room is 624 inches.

We need 657 tiles to cover the floor.

We need to add 66 extra tiles to account for the overage due to grout and waste.

What is a rectangle?

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

Length = 10 ft 9in

Width = 15ft 3 in

Perimeter = 2 (Length + Width)

Length = 10 ft 9 in = (10 x 12) + 9 = 129 in.

Width = 15 ft. 3 in. = (15 x 12) + 3 = 183 in

Perimeter.

= 2(129 + 183)

= 624 in.

Area = Length x Width

Area = 129 in. x 183 in

Area == 23,607 in²

Each tile covers an area of 6 in. x 6 in

Area of tiles = 36 in²

So,

The number of tiles required.

= Area ÷ Tile area

= 23,607 in² ÷ 36 in²

≈ 656.3 tiles.

10% of 657

= 10/100 x 657

= 0.1 x 657

= 65.7

= 66

Thus,

The perimeter of the room is 624 inches.

We need 657 tiles to cover the floor.

We need to add 66 extra tiles to account for the overage due to grout and waste.

Rays KV and JP

The point of intersection is given as:

Point M

When the rays KV and JP intersect at point M, the following angles are created

KMJ, JMV, PMV and PMK

Such that:

KMJ and PMV are vertical angles JMV and PMK are vertical angles

The above means that angles KMJ and PMV are equal and

Answers

Answer:

a < c < b

Step-by-step explanation:

The sum of the interior angles of a triangle is 180°

Therefore, the measure of the missing angle (opposite side c) is:

180° - 69° - 54° = 57°

Relationship between sides and interior angles of any triangle:

The shortest side is always opposite the smallest angleThe longest side is always opposite the largest angle

Therefore, from inspection of the triangle:

a is opposite the smaller angle of 54°c is opposite the angle of 57°b is opposite the largest angle of 69°

So the side lengths in increasing order are:

a < c < b

Rest angle:-

180-(69+54)180-12357

Note that smaller side has smaller opposite angle

Hence the order is

a<c<b

The value of (1/2)x⁴ - (1/4)x² when x = 2 is 7.

What are Expressions?

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given expression is (1/2)x⁴ - (1/4)x².

We have to calculate the value of the expression when x = 2.

Substitute x = 2 in the expression.

(1/2)x⁴ - (1/4)x² = (1/2) (2)⁴ - (1/4) (2)²

= (1/2) × 16 - (1/4) × 4

= 16/2 - 4/4

= 8 - 1

= 7

Hence the value of the expression when x = 2 is 7.

please help me with this graph problem. NO LINKS!!!

Answers

Step-by-step explanation:

Eric runs for 4 min and walks for 8 min.

The distance covered is

4*200 + 8*80 = 800 + 640 = 1440

The goal of 1600 m is not met, needs additional 160 m

The equation of distance is

d = 200x + 80y

For d = 1600, the equation is

200x + 80y = 1600

Simplified form of it

2.5x + y = 20

Some combinations of x and y to make the equation right

x = 2, y = 15x = 4, y = 10x = 6, y = 5

See the attached graph for more combinations, where the first coordinate represents running time and the second coordinate - walking time

Answer:

Part (a)

Given:

Average running speed = 200 m/minAverage walking speed = 80 m/min

If Eric runs for 4 minutes ⇒ 200 x 4 = 800 m

If Eric walks for 8 minutes ⇒ 80 x 8 = 640 m

Total distance covered = 800 + 640 = 1440 m

Therefore, he is 160 m away from his 1600 m goal.

Part (b)

Let x = number of minutes Eric runs

Let y = number of minutes Eric walks

Let d = total distance Eric covers

Equation: d = 200x + 80y

Part (c)

Set d = 1600, then rewrite to make y the subject:

200x + 80y = 1600

⇒ 5x + 2y = 40

⇒ 2y = 40 - 5x

⇒ y = 20 - 2.5x

Now find ordered pairs (points on the line):

x-intercept (y = 0): 20 - 2.5x = 0 ⇒ x = 8 ⇒ (8, 0)y-intercept (x = 0): 20 - 2.5(0) = 20 ⇒ (0, 20)when x = 4: 20 - 2.5(4) = 10 ⇒ (4, 10)

Part (d)

Plot (8, 0) (0, 20) and (4, 10) and connect with a straight line.

(see attached graph)

From inspection of the graph, other combinations of running and walking times for which Eric would cover 1600 meters are:

2 minutes running, 15 minutes walking6 minutes running, 5 minutes walking

An ellipse has vertices along the major axis at (0,1) and (0,-9). The foci of the ellipse are located at (0,-1) and (0,-7). The equation of the ellipse is the form below. (y-k)^2/a^2 + (x-h)^2/b^2 = 1 Which is a correct value for one of the variables shown in the equation?
a = 10
b = 4
h = 3
k = 0

Answers

The equation of the ellipse in standard form with vertices along the major axis at (0, 1) and (0, -9) and the foci of the ellipse at (0, -1) and (0, -7) is (y+4)²/16 + x²/25 = 1.

How to derive an equation of the ellipse based on the information of the major axis and foci

The location of the center of the ellipse is the midpoint of the line segment between the ends of the major axis, that is:

(h, k) = 0.5 · (0, 1) + 0.5 · (0, -9)

(h, k) = (0, -4)

The length of the major semiaxis (b) is 5 and the distance between the center and any of the foci (c) is 3. Then, the length of the minor semiaxis is:

[tex]a = \sqrt{b^{2}-c^{2}}[/tex] (1)

a = 4

Lastly, we substitute all the variables and conclude that the equation of the ellipse is (y+4)²/16 + x²/25 = 1. [tex]\blacksquare[/tex]

Answers

Answer ¹ ↷$ 12

Solution ↷

The amount of money Trevon had last Friday⇢$29

The total amount of money he has after cleaning the attic⇢$41

So,

The amount of money he received after cleaning the attic ⇢ Total money he has after cleaning the attic - The money he had last Friday

⇢ $41-$29⇢$12

Thus ,he received $ 12 for cleaning up the attic.

Answer²↷$9.02Solution ↷

The cost of the game ⇢$30.98

The amount of money she gave to the cashier ⇢$40

The amount she'll receive back⇢ the amount of money she gave to the cashier - the cost of the game

⇢$ 40 - $ 30.98⇢$ 9.02

Hence , she'll receive $ 9.02 back from the cashier.

Answer:

Question 1

Given:

Last Friday Trevon had $29He received money for cleaning the atticHe now has $41

To calculate the money Trevon received for cleaning the attic over the weekend, we need to find the difference between the money he started with and the money he now has. To find the difference, subtract the smaller number from the bigger number:

⇒ Money Trevon received = Money he has now - money on Friday

= $41 - $29

= $12

Therefore, Trevon received $12 for cleaning the attic over the weekend.

Question 2

Given:

Cost of game = $30.98Money gave the cashier = $40

To calculate the change Jenny received from the cashier, we need to find the difference between the two amounts. To find the difference, subtract the cost of the game from the money Jenny gave to the cashier:

⇒ Change = money given - cost of game

= $40 - $30.98

= $9.02

Therefore, Jenny received $9.02 in change from the cashier after paying for a game that costs $30.98 with $40.
