Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y + 5x = 1

5y - x = 5

Step 2: Rewrite Systems

y + 5x = 1

Subtract 5x on both sides:                    y = 1 - 5x

Step 3: Redefine Systems

y = 1 - 5x

5y - x = 5

Step 4: Solve for x

Substitution

Substitution in y:                      5(1 - 5x) - x = 5Distribute 5:                             5 - 25x - x = 5Combine like terms:                5 - 26x = 5Isolate x term:                          -26x = 0Isolate x:                                   x = 0

Step 5: Solve for y

Define equation:                    5y - x = 5Substitute in x:                       5y - 0 = 5Subtract:                                 5y = 5Isolate y:                                 y = 1

At a movie theater, the price of 2 adult tickets and 4 child tickets is $48. The price of 5 adult tickets and 2 child tickets is $64. What is the ticket price for one adult and for one child?

Answers

Answer:

10$ for an adult and 7$ for a child

Step-by-step explanation:

price for an adult = a

price for a child = b

2a + 4b = 48.............(i)

5a + 2b = 64.............(ii)

make a subject of the formula in equation (i)

2a = 48 - 4b

divide through by 2

a = 24 - 2b

Insert the value of a in equation (ii)

5(24 - 2b) + 2b = 64

120  - 10b + 2b = 64

collect like terms

- 8b = 64 - 120

-8b = -56

divide both sides by -8

b = 7

insert the value of b in equation(i)

2a + 4(7) = 48

2a + 28 = 48

2a = 48 - 28

2a = 20

divide both sides by 2

a = 10

The price for one adult is $10 while the price for one child is $7

how to solve: 20^2+5^2=x^2, then you take the square root, therefore x=20.62

Answer:

Simple!

Step-by-step explanation:

The triangle is obviously a right triangle, meaning, we can use the Pythagorean Theorem to solve for x!

(The Pythagorean Theorem is where [tex]a^2=b^2+c^2[/tex], or the length of the hypotenuse (side opposite to the 90 degree angle) squared is equal to the length of one leg squared plus the other leg squared).

To put it simply:

[tex]x^2=20^2+5^2[/tex]

Now to solve!

[tex]x^2=400+25\\x^2=425\\x=\sqrt{425} \\x=5\sqrt{17}[/tex]

This cannot be simplified further, so that's your answer!

Hope this helps!

Amita's kitchen is rectangular with an area of 3 3 4 square meters. The width of the kitchen is 1 1 2 meters. What is the length, in meters, of Amita's kitchen?

Answers

Answer:

2 1/2 meters

Step-by-step explanation:

Amita's kitchen is rectangular with an area of 3 3 /4 square meters. The width of the kitchen is 1 1/ 2 meters. What is the length, in meters, of Amita's kitchen?

The formula for the area of a rectangle = Length × Width.

To find the length our formula becomes : Area/Width

In the question,

Area = 3 3/4 m²

Width = 1 1/2 m

Length of the rectangular kitchen

= 3 3/4 m² ÷ 1 1/2 m

= 15/4 m² ÷ 3/2 m

= 15/4 m² × 2/3 m

= 5/2 m

= 2 1/2 m

The length of the rectangular kitchen is 2 1/2 meters

Solve 10=5m/4
Im Confused, Please Help

Answers

Answer:

m = 8

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

10 = 5m/4

Step 2: Solve for m

Multiply 4 on both sides:                    40 = 5mDivide 5 on both sides:                      8 = mRewrite:                                               m = 8

Step 3: Check

Plug in m into the original equation to verify it's a solution.

Substitute in m:                    10 = 5(8)/4Multiply:                                10 = 40/4Divide:                                   10 = 10

Here we see that 10 does indeed equal 10.

∴ m = 8 is the solution to the equation.

Robert earns $8.65 per hour mowing lawns. A) Write a rule for money m as a function of the number of hours h spent mowing lawns. B) How much does Robert earn if she works 3 hours and 25 minutes?

Answers

Answer:

A) [tex]m=8.65h[/tex]

B) $29.58

Step-by-step explanation:

Earnings per hour = $8.65

To find:

A) Write a rule for money m as a function of the number of hours h spent mowing lawns.

Earnings done in one hour = $8.65

Number of hours = [tex]h[/tex]

To find the total earnings, [tex]m[/tex] as a function of number of hours [tex]h[/tex], we need to multiply per hour earnings with number of hours [tex]h[/tex].

Therefore, the equation is:

[tex]m=8.65h[/tex]

B) How much does Robert earn if she works 3 hours and 25 minutes?

First of all, let us convert 3 hours and 25 minutes to hours.

3 hours 25 minutes = 3.42 hours

Therefore, total earnings are:

[tex]m = 8.65\times 3.42 = \$29.58[/tex]

which is another way to write 42 + 63?

Answers

Answer:

B

Step-by-step explanation:

The sum of 42 + 63 is equal to 105.

B is the only answer that matches the sum of 42 and 63.

7 * 15 = 105

Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.

Answers

Answer:   B) 3

Explanation:

Start at a point like (0,2) which is on the blue f(x) line.

Move upward until you reach the red g(x) line. You should move up 3 units. Every point on f(x) follows the same pattern to land on a corresponding point on g(x). Therefore, this moves the entire blue line up 3 units.

This leads to k = 3

So g(x) = f(x) + 3

Answer: 3

Step-by-step explanation: This is because I took the test and because if you look at the graph its on 5 and 2. An easy way to look at it is what is 5-2 but you'd have to figure out what the answer was first. Between 5 and 2 is 3. Hope this helped!

Rectangle FGHJ has coordinates F(-8, 6), G(8, 6), H(8,-6), and J(-8, -6). The rectangle is dilated by a scale factor of v with the origin as the center of dilation to form rectangle F'G'H'J'. Which ordered pair represents the coordinates of vertex H'?

Answers

Answer:

H'(8v,-6v)

Step-by-step explanation:

Here coordinate of H is (8,-6). We are dilating it using the rule (x,y)-->(kx,ky) where 'k' is scale factor.

For our problem , the dilation factor is "v"

So, image would be (8v,-6v)

What are similar triangles?

Those triangles look the same but are different in size.

And in similar triangles,

the corresponding sides are in proportion to each other and the corresponding angles are equal to each other.

Given information:

SM = 27, angle SMA = 31 degrees, MA = 15, DL = 9, LE = 5 and Angle DLE = 31 degrees.

From the given information, we know that angle SMA is congruent to angle DLE because they both have a measure of 31 degrees. However, we do not have any information about the other angles in the two triangles.

To check if the corresponding sides are proportional, we can compare the ratios of the corresponding side lengths:

SM/ DL = 27/9 = 3

MA/LE = 15/5 = 3

Since the ratio of SM to DL is equal to the ratio of MA to LE, we know that the corresponding sides are proportional.

Therefore, we can use the Similarity-SAS (Side-Angle-Side) postulate to conclude that the triangles are similar. The postulate states that if two pairs of corresponding sides are proportional and the included angles are congruent, then the triangles are similar.

The answer is (C) Similar - SAS.
