the sum of two numbers equals 49.The sum of the larger number and twice the smaller number is 70. what are the numbers.

Tell me the steps!

Answers

Answer 1
[tex]x + y = 49 \\ x + 2y = 70[/tex]

[tex]x = 49 - y[/tex]

Substitute that into,
[tex]49 - y + 2y = 70 \\ y = 21[/tex]

Substitute that into,
[tex]x = 49 - 21 \\ x = 28[/tex]

Answer check :
[tex]21 + 28 = 49 \\ 28 + 2(21) = 28 + 42 = 70[/tex]

Answer : The numbers are 21 and 28.

Hope this helps. - M
Answer 2

The problem is solved using a system of equations to find that the two numbers in question are 21 and 28.

To solve the problem involving two numbers where the sum equals 49 and the sum of the larger number and twice the smaller number equals 70, we need to form a system of linear equations and solve for the unknowns. Let's denote the smaller number as s and the larger number as l.

The sum of the two numbers is 49: s + l = 49.The sum of twice the smaller number and the larger number is 70: 2s + l = 70.

Subtract the first equation from the second to find the value of s.

2s + l - (s + l) = 70 - 49

Which simplifies to:

s = 21

Substitute the value of s into the first equation:

21 + l = 49

And solve for l:

l = 28

Therefore, the smaller number is 21 and the larger number is 28.

Find an equation for the inverse of the relation y=6x-3. Show how you found the inverse equation.

Answers

Hi there! The answer is y = 1/6x + 1/2

To find the inverse function x and y need to switch places.

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

Now rewrite the equation, until it will be in standard form (slope-intercept form) again.
[tex]x = 6y - 3[/tex]

Add 3.
[tex]x + 3 = 6y[/tex]

Switch sides.
[tex]6y = x + 3[/tex]

Divide both sides by 6.
[tex]y = \frac{1}{6} x+ \frac{3}{6} \\ y = \frac{1}{6} x + \frac{1}{2} [/tex]

Hence, the answer is y = 1/6x + 1/2.
~ Hope this helps you!

The inverse of the relation y=6x-3 is y = (x + 3) / 6.

To find an equation for the inverse of the relation y=6x-3, we need to follow a series of steps which involves swapping the variables, and then solving for the new y.

Start with the initial equation: y = 6x - 3.

Swap the variables x and y: x = 6y - 3.

Solve for y to find the inverse relation: Add 3 to both sides to get x + 3 = 6y, then divide both sides by 6 to isolate y, resulting in y = (x + 3) / 6.

The solution is 17 chairs

The number of chairs placed is 17 and the inequality equation is 2x < 35 , where x is the number of chairs

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the number of chairs be represented as x

Now , the inequality equation will be

Each chair installed in the new chapel requires 24 inches of clearance

So , 24 inches = 2 feet

And , each row cannot be greater than 35 feet

So , the number of 2 feet chairs = 2x

And , 2x cannot be greater than 35 feet

Substituting the values in the equation , we get

2x < 35   be equation (1)

Divide both sides of the equation by 2 , we get

x < 17.5

x < 17 chairs

Therefore , the value of x is 17 chairs

Hence , the number of chairs is 17 chairs

You can make 20 two topping sandwiches.

A sandwich shop offers the following toppings. How many two topping sandwiches can you make?

-lettuce

-tomato

-bacon

-cheese

-mustard

Solution:

There are five toppings available and the five toppings are lettuce, tomato, bacon, cheese, mustard.

We need to make 2 topping sandwiches.

So, we can select any 2 toppings from the available 5 toppings

So, we must use combination here

So, the number of two topping sandwiches is 5 combination 2

Or, Number of 2 topping sandwiches= 5 C 2

The formula is, n C r =[tex]\frac{n!}{(n-r)!r!}[/tex]

So, The number of 2 topping sandwiches= 5 C 2 =[tex]\frac{5!}{(5-2)!2!}[/tex]

The number of 2 topping sandwiches=[tex]\frac{5!}{(3)!2!}[/tex]

The number of 2 topping sandwiches=[tex]\frac{(5*4*3*2*1)}{(3*2*1)(2*1)}[/tex]

The number of 2 topping sandwiches=[tex]\frac{120}{12}[/tex]

Mitch does not know the correct answer to two multiple choice questions. The choices are A,B,C, and D. If Mitch just guesses, what is the probability that Mitch will guess both answers correctly?

Answers

Both chances to success are 1/4. If you want the first AND the second to be successful, you have to multiply the chances, so the answer is

1/4 * 1/4 = 1/16

Final answer:

Mitch has a 1/16 probability of guessing both multiple-choice answers correctly when randomly guessing among four options.

Explanation:

If Mitch guesses on two multiple-choice questions with choices A, B, C, and D, the probability of guessing both correctly is calculated as follows: The probability of correctly guessing one question is 1/4 (since there are 4 possible choices, and only one is correct). To find the probability of guessing both correctly, we multiply the probabilities of each independent event. Thus, the probability of guessing the first question correctly AND the second question correctly is 1/4 × 1/4 = 1/16.

name the following triangle according to its angles and sides: 120 degrees, 35 degrees, 25 degrees

Answers

The answer is a scalene triangle because all its sides and angles are unequal

Final answer:

The triangle with angles of 120 degrees, 35 degrees, and 25 degrees is classified as an obtuse scalene triangle because it has one angle greater than 90 degrees and all angles of different measures.

Explanation:

To classify the triangle with angles of 120 degrees, 35 degrees, and 25 degrees, we first confirm that the sum of its angles is 180 degrees, which is true for any plane triangle. Given this sum, we can classify the triangle based on its angles and sides.

A triangle with one angle greater than 90 degrees is called an obtuse triangle, as it has an obtuse angle (greater than 90 degrees). Since this triangle has a 120-degree angle, it fits that definition. Furthermore, because all the angles are different, we can classify it as a scalene triangle, meaning all sides have different lengths. Therefore, the correct classification for this triangle is an obtuse scalene triangle.

Kurt bought a bike for $149.95. Eric bought a bike that had been $169.50 but was marked 1/5 off. How much less did Eric’s bike cost than Kurt’s?

Answers

Eric's bike costed $14.85 dollars less than kurts

After calculating the discount and subtracting it from the original price, Eric's bike cost $135.60, which is $14.35 less than Kurt's bike that cost $149.95.

To determine how much less Eric paid for his bike compared to Kurt's bike, we need to calculate the discount Eric received and subtract it from the original price of his bike. Then, we'll compare it to the price Kurt paid for his bike.

First, we calculate Eric's discount by multiplying the original price of the bike, $169.50, by 1/5 (which represents the 20% discount):

$169.50 times  15= $33.90.

Now, subtract this discount from the original price to find out how much Eric paid for the bike:

$169.50 - $33.90 = $135.60.

Finally, to find out how much less Eric's bike cost than Kurt's, we subtract the price Eric paid from the price Kurt paid:

$149.95 - $135.60 = $14.35.

Eric's bike cost $14.35 less than Kurt's.

Solve the system of equations. y = 7x + 43 y = 2x + 13 a. ( -6, 1) c. ( 6, 1) b. ( 6, -1) d. No solution

Answers

Hello there!

y = 7x + 43
y = 2x + 13

We wanna solve y = 7x + 43 for y in y = 2x + 13

What does that even mean? Well it simply means that we gonna replace y by 7x + 43.

y = 2x + 13

7x + 43 = 2x + 13

Subtract 2x on both sides

7x + 43 - 2x = 2x + 13 - 2x

5x + 43 = 13

Now we can subtract 43 on both sides

5x + 43 - 43 = 13 - 43

5x = -30

Then divide both sides by 5

5x/5 = -30/5

x = -6

Now since we have the value for x, we gonna use that value to find y.

We can do that by substituting -6 for x in y = 7x + 43

But what does that mean? It means that in y = 7x + 43, we gonna replace the x by -6

y = 7x + 43

y  = 7(-6) + 43

y = -42 + 43

y = 1

Thus,

The answer is: x = -6 and y = 1

The correct answer is option A (-6,1).

The g(x) function has been scaled by a factor of 2. In other words, each point on g(x) is twice as high as its corresponding point on f(x). Specifically for example, the point (1,1) has been doubled to (1,2). Overall, this vertically stretches out the parent function graph.

Answers

The calculated quotient of the expression (14x³ - 21x² + 28x) ÷ 7x is 2x² - 3x + 4

How to evaluate the quotient expression

From the question, we have the following parameters that can be used in our computation:

(14x³ - 21x² + 28x) ÷ 7x

Factor out x in the numerator

So, we have

(14x³ - 21x² + 28x) ÷ 7x = x(14x² - 21x + 28) ÷ 7x

Evaluate the quotient

(14x³ - 21x² + 28x) ÷ 7x = (14x² - 21x + 28) ÷ 7

Divide through by 7

(14x³ - 21x² + 28x) ÷ 7x = 2x² - 3x + 4

Hence, the quotient of the expression is 2x² - 3x + 4

Answers

General equation of parabola:  y-k = a(x-h)^2

Here the vertex is at (0,0), so we have y-0 = a(x-0)^2, or y = ax^2

All we have to do now is to find the value of the coefficient a.

(1,2) is on the curve.  Therefore, 2 = a(1)^2, or 2 = a(1), or a = 2.

The equation of this parabola is y = 2x^2.

The vertex form of the equation of a parabola with a vertex at (0,0) and passing through the point (1,2) is [tex]y=2x^2.[/tex]

The vertex form of a parabola is given by: [tex]y = a(x - h)^2 + k[/tex] where (h, k) is the vertex of the parabola.

In this case, the vertex is (0, 0), so h = 0 and k = 0.

Therefore, the equation becomes: [tex]y = a(x - 0)^2 + 0.[/tex] Simplifying further, the equation becomes: [tex]y = ax^2[/tex].

Now, we need to find the value of 'a.' To do this, we can use the given point (1, 2). Substitute these values into the equation:

[tex]2 = a(1)^2[/tex].

Therefore, 'a' is 2. So, the final equation in vertex form is: [tex]y = 2x^2.[/tex]

So, the correct answer is A. [tex]Y = 2x^2.[/tex]

Percent wearing red is 66.67%

There are 54 people at the party.

18 people are wearing red which means that 36 people are not wearing red

54 - 18 = 36

The fraction [tex]\frac{36}{54}[/tex] represents the 36 people at the party that are wearing no red. We can find what percent of the people at the party are not wearing red by turning [tex]\frac{36}{54}[/tex] into a percent.

[tex]\frac{36}{54}[/tex] can be reduced to [tex]\frac{2}{3}[/tex]  by dividing both the numerator and denominator by the greatest common factor of 36 and 54.

2 ÷ 3 = 0.667
