Answer:  x = 0  y = –3

Step-by-step explanation:

We can solve this system by substitution.

use the second equation as a value for x.

Then substitute that value  in place of x in the first equation and solve for y.

6x - 5y = 15 becomes

6(y + 3) - 5y = 15  Distribute 6 × parentheses

6y + 18 - 5y = 15 combine like terms

6y -5y + 18 = 15

y + 18 = 15   Subtract 18 from both sides.

y =15 -18

y = –3

Use this value for y in either equation to solve for x

6x - 5(-3) = 15

6x + 15 = 15    Subtract 15 from both sides, divide by 6 (seems silly!)

x = 0

OR in he second equation,

x = -3 + 3  

Again, x = 0

hehehehehehehe unknown sorry not sorry

Answer:

The length is 43 feet, the width is 15 feet, and the area is 645 square feet

Step-by-step explanation:

Let us solve the question

∵ The drawing plan shows a rectangle that is 17.2 inches by 6 inches

∴ The drawing length = 17.2 inches

∴ The drawing width = 6 inches

∵ The scale in the plan is 2 in.: 5 ft

→ By using the ratio method

→  inches: feet

→  2         : 5

→  17.2     : L

→  6         : W

→ By using the cross multiplication

∵ 2 × L = 17.2 × 5

∴ 2L = 86

→ Divide both sides by 2

∴ L = 43 feet

∴ The actual length is 43 feet

→ By using the cross multiplication

∵ 2 × W = 6 × 5

∴ 2W = 30

→ Divide both sides by 2

∴ W = 15 feet

∴ The actual width is 15 feet

∵ The area of the rectangle is A = L × W

∵ L = 43 feet

∵ W = 15 feet

→ Substitute them in the rule of the area

∴ A = 43 × 15

∴ A = 645 feet²

∴ The actual area is 645 square feet

Answer:

y = 12x

Step-by-step explanation:

Given that:

y = cost of making a special order cupcake

A dozen of special order cupcakes = 12 pieces

Let the cost of extra ingredient for making a special order cupcake = x

Hence the cost y of making a dozen of such special order will be :

y = extra cost per order * number of orders

y = 12x

Answer: 3.333 + miles per hour

Step-by-step explanation:

Distance walked = 5+ miles

Time taken to cover distance = (8:15 am - 6:45am) = 1 hour 30 minutes = 1.5 hours

Average walking rate = (total distance walked / total time taken)

Average walking rate = (5 + miles / 1.5 hours)

Average walking rate = 3.333 + miles per hour

Answer:

3 1/2 (miles=5 1/4)

Step-by-step explanation:

6:45 a.m. - 8:15 a.m. = 1 hour 30 mins = 1 5/10

5 1/4 / 1 5/10 = 3 1 /2

Answer:

The car will be able to travel 2,000 miles in 2 hours

Step-by-step explanation:

The rule of the distance is D = v × t, where

∵ The car has a top speed of 1,000 miles each hour

∴ v = 1,000 miles/hour

∵ The car will travel for 2 hours

∴ t = 2 hours

→ By using the rule of the distance

∵ D = v × t

→ Substitute the values of v and t in the rule to find D

∴ D = 1,000 × 2

∴ D = 2,000 miles

∴ The car will be able to travel 2,000 miles in 2 hours

Division of a given length of an item into required length, would result to a length lesser than the initial length of the fabric. This ensures that the required length of each piece is [tex]\frac{1}{12}[/tex].

The given fabric has been divided into equal proportion. The length of the small pieces of the given fabric can be determined by dividing the total length of fabric by the number of pieces.

Let the length of each piece required be represented by x.

So that;

given that the total length of the fabric is 2 yards, then;

24x = 2

divide both sides by 24 to have;

x = [tex]\frac{2}{24}[/tex]

  = [tex]\frac{1}{12}[/tex]

x = [tex]\frac{1}{12}[/tex] yards.

Thus, each piece of the 24 pieces of fabric has a length of [tex]\frac{1}{12}[/tex] yards.

The simplest form of the given equation 2⁻⁴/4⁰ is 1/16.

A mathematical expression is simplified when it is replaced with a simpler, typically shorter, equivalent statement. Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.

Given an expression 2⁻⁴/4⁰

simplifying it

Answer:

$126

Step-by-step explanation:

$252/$18=$14 dollars per hour.

now take 14*9 and you get $126.

Answer:

$126

Step-by-step explanation:

Okay, so to solve this question, we need to get from 18 (hours) to 9. To do this, we obviously divide 18 by 2. Since we did this, we now have to do the same thing with the other side ($252.) 252 divided by 2 is 126. This means that if Chau made $252 in 18 hours,  he will make $126 in 9 hours.

Answer:

D divide both the numerator and denominator by cos(x)cos(y)

Step-by-step explanation:

just took test

The derivation of tangent sum identity taken to the expression in Step 3 to give an expression for Step 4 is option D; divide both the numerator and denominator by cos(x)cos(y).

The trigonometric identities is the relationship between the different trigonometric ratios.

These trigonometric identities are the basic formulae that are true for all the values of the reference angle.

For the given situation, the derivation for the tangent sum identity is given in the table below.

The derivation follows the steps,

[tex]\dfrac{sin (x+y)}{cos (x +y)}[/tex]

we know that,

sin (x + y) = sin x cos y + cos x sin y

cos (x + y) = cos x cos y - sin x sin y

Substitute;

[tex]\dfrac{sin x cos y + cos x sin y}{cos x cos y - sin x sin y}[/tex]

Divide each term by cos x cos y

[tex]\dfrac{\dfrac{sin x cos y}{cos x cos y} + \dfrac{cos x sin y}{cos x cos y} }{\dfrac{cos x cos y}{cos x cos y} - \dfrac{sin x sin y}{cos x cos y} }[/tex]

Now, [tex]\dfrac{tan x + tan y}{1 - tan x tan y}[/tex]

Hence we can conclude that the derivation of tangent sum identity taken to the expression in Step 3 to give an expression for Step 4 is option D; divide both the numerator and denominator by cos(x)cos(y).
