2. Substitute the value for x into the second equation:

3. Solve for y:

4. Substitute y into either original equation:

5. Write the solution as an ordered pair:

x = 7 – 3y

2(7 – 3y) + 4y = 8

Answers

Answer:

The solution to the system of equation is: (-2,3)

Step-by-step explanation:

We need to find the solution to the system of equations: x + 3y = 7 and 2x + 4y = 8

I am placing steps for each point given

1. Isolate x in the first equation:

First equation is:

x+3y=7

Isolating x:

x=7-3y

2. Substitute the value for x into the second equation:

Second equation is:

2x+4y=8

Putting value of x: x=7-3y

2(7-3y)+4y=8

3. Solve for y:

2(7-3y)+4y=8

Multiply 2 with terms inside the bracket

14-6y+4y=8

-2y=8-14

-2y=-6

y=-6/-2

y=3

So, we get value of y: y=3

4. Substitute y into either original equation:

Putting value of y: y=3 in equation 1

x+3y=7

x+3(3)=7

x+9=7

x=7-9

x=-2

So, we get value of x: x=-2

5. Write the solution as an ordered pair:

After solving the equation we get:

x = -2 and y = 3

The ordered pair is: (-2,3)

Answer:

-2,3

Step-by-step explanation:

Isolate x in the first equation:

Substitute the value for x into the second equation:

Apply the distributive property to factor out the greatest common factor of all three terms. 24c + 36d + 18 =

Answers

Answer:

[tex]24c + 36d + 18[/tex] [tex]= 6(4c + 6d+3)[/tex]

Step-by-step explanation:

Given

[tex]24c + 36d + 18[/tex]

Required

Factorize

[tex]24c + 36d + 18[/tex]

Expand each term

[tex]6*4c + 6 *6d+6 *3[/tex]

Factor 6 out of the expression

[tex]6(4c + 6d+3)[/tex]

Hence:

[tex]24c + 36d + 18[/tex] [tex]= 6(4c + 6d+3)[/tex]

Jordan drives for three hours at an average of 60 miles per hour what is the distance in miles he drives during that time

Answers

Answer:

d = 180 miles

Step-by-step explanation:

Given that,

The average speed of Jordan, v = 60 mph

Time, t = 3 hours

We need to find the distance he drives during that time. Average speed is equal to the distance divided by time taken.

v = d/t

[tex]d=v\times t\\\\d=60\times 3\\\\d=180\ \text{miles}[/tex]

So, the distance driven during that time is 180 miles.

Consider all seven-digit numbers that can be created from the digits 0-9 where the first and last digits must be even and no digit can repeat. Assume that numbers can start with 0. What is the probability of choosing a random number that starts with 4 from this group

Answers

Answer:

[tex]P_4= 0.2[/tex]

Step-by-step explanation:

From the question we are told that

Consider all seven-digit numbers

Created from the digits 0-9

Generally number of digits that starts with 6 is mathematically given as

The total amount of digits from 0-9(0,1,2,3,4,5,6,7,8,9 = 10

The total amount of even digits within 0-9 (0,2,4,6,8) = 5

The total amount of 3-digit numbers giving the first and last digits to be even = 5 * 10 * 5 = 250

The total 3-digit numbers giving the first digit is 4 and last digit is even = 1 * 10 * 5 = 50

Probability the number starts with 4

[tex]P_4 = \frac{50}{250}[/tex]

[tex]P_4= 0.2[/tex]

Answers

Answer:

1 and 2

Step-by-step explanation:

If y was 1: -2 x 1 + 18 = -2 + 18

= 16 This works

If y was 2: -2 x 2 + 18 = -4 + 18

= 14 This works

If y was 3: -2 x 3 + 18 = -6 + 18

= 12 This does not work since -2y + 18 has to be greater than 12.

Step-by-step explanation:

-x+8+3x=x-6

2x+8=x-6

2x-x=-6-8

x= -14

The value of x in the equation is -14

How to solve the equation?

We have:

-x+8+3x=x-6

Collect like terms

3x - x - x = -6 - 8

Evaluate the like terms

x = -14

What will be the return value of =SUM({10;15;20;25;30})?

Answers

Answer:

The return value is 100

Step-by-step explanation:

Given

[tex]=SUM({10;15;20;25;30})[/tex]

Required

Determine the return value

In Microsoft Office Excel, the sum of values is represented as:

[tex]=SUM({a_1;a_2;a_3;.....;a_n})[/tex]

This is interpreted as:

[tex]SUM= a_1;a_2+a_3+.....+a_n[/tex]

So, in the case of:

[tex]=SUM({10;15;20;25;30})[/tex]

The return value is:

[tex]Value= 10 + 15+ 20 + 25 + 30[/tex]

[tex]Value= 100[/tex]

Hence, the return value is 100

The Case of Modern Wheatby Alisa Scerrato The gluten-free lifestyle has recently become a hot topic in the United States. "Gluten-free" products and advertisements seem to be everywhere. What is this thing called gluten, and why are so many people suddenly cutting it out of their diets when they have been consuming it for years without debate? Gluten is a general name for protein found in wheat, rye, barley, and triticale. It acts as a glue to help certain foods maintain their shape. Most people think that gluten exists only in bread, baked goods, and cereals, but it is also found in soups, sauces, salad dressings, and many other foods that are less commonly known to be associated with wheat. Some scientists claim that gluten is a strange protein and inherently difficult for humans to digest. The reason for this is that there has been a change in the way wheat is produced in the United States over the past several years. Modern cultivation of wheat is done in order to boost the protein content. Research has shown that gluten being used in "modern wheat" makes breaking down certain foods hard on the stomach. Some Americans just happen to react more severely than others to gluten. The symptoms of gluten intolerance vary from person to person. Eating gluten has recently been discovered to contribute to such medical issues as irritable bowel syndrome, arthritis, acne, and depression, just to name a few. Another more serious reaction to the consumption of gluten is referred to as celiac disease. About 2 million people in the United States suffer from this disease. Celiac disease is an autoimmune digestive disease that interferes with the absorption of nutrients from food. This disease is serious as it can lead to a number of issues including neurological disorders, reduced bone density, and sometimes cancer. Eating in restaurants or in other peoples homes is challenging for people with celiac disease because knowing which foods contain gluten can be difficult. In general, people should educate themselves about the ingredients found in different foods, but people who are particularly sensitive to gluten have to be even more diligent. There are no pharmaceutical cures for gluten intolerance, so some people must manage their gluten intake by being aware and adhering to strict diets. While celiac disease is the most extreme case, eating a low or no gluten diet can indeed provide health benefits for many people. In fact, many Americans have found that abstaining from gluten has helped improve their lives. Select ALL the correct answers.Which two statements from the passage best illustrate the central ideas?Gluten is a general name for protein found in wheat, rye, barley, and triticale.Eating gluten has recently been discovered to contribute to such medical issuesEating in restaurants or in other people's homes is challenging for people with celiac diseaseThe gluten-free lifestyle has recently become a hot topic in the United States.Some Americans just happen to react more severely than others to gluten.
