What value of x makes the following equation true?
15+3x=3(2−2x)

Answers

Answer 1

Answer:

[tex]\boxed {x = -1}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]15 + 3x = 3(2 - 2x)[/tex]

-Use Distributive Property:

[tex]15 + 3x = 3(2 - 2x)[/tex]

[tex]15 + 3x = 6 - 6x[/tex]

-Take [tex]6x[/tex] and add it to [tex]3x[/tex]:

[tex]15 + 3x + 6x = 6 + 6x - 6x[/tex]

[tex]15 + 9x = 6[/tex]

-Subtract both sides by [tex]15[/tex]:

[tex]15 - 15 + 9x = 6 - 15[/tex]

[tex]9x = -9[/tex]

-Divide both sides by [tex]9[/tex]:

[tex]\frac{9x}{9} = \frac{-9}{9}[/tex]

[tex]\boxed {x = -1}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]-1[/tex].

Name the relationship: complementary, linear pair, vertical, alternate interior, corresponding, or
alternate exterior.

Answers

Answer:

Linear pair

Step-by-step explanation:

Angle a and angle b are adjacent angles formed at the point of interception of two straight lines that intersects.

Thus, they are angles formed on a straight line. Angles on a straight line sum up to give 180°, since a straight line angle measures 180°.

Thus, angle a and angle b are regarded as linear pair angles. They are supplementary.

Garret bought 7 bags of apples. The red Apple came in bags of 5 and green came in bags of 2. Garret bought a total of 17 apples. How many of each type of apple did he buy.

Answers

Answer:

6 green apple bags and 1 red apple bags

Step-by-step explanation:

6 green apple bags = 12 apples

1 red apple bag= 5 apples

12+5 =17 apples

6+1= 7 bags

Answer:

1 bag of red and 6 bags of green apples.

Step-by-step explanation:

We need to pick 7 bags of apples of different sizes so that the total number of apples = 17.

If  Garret bought 1 bag of 5 then the other 12 apples would have to come in 6 bags.

That is 6 bags of 2 apples.

question: Your mass on earth is 50 kilograms. What is your mass on the moon?

Answers

Answer:

No matter if you are on Earth, the moon or just chilling in space, your mass does not change. But your weight depends on the gravity force; you would weigh less on the moon than on Earth, and in space you would weigh almost nothing at all. Where ever you are, your mass will always stay the same.

Answer:

50 kilograms

Step-by-step explanation:

Mass never changes, and is constant everywhere. The weight is what changes. If you weigh 50 kg on Earth, you'll weigh 50 kg everywhere else in the universe. That's because the amount of matter in you cannot change.

Y=-1/2x+2 is the correct answer in slope intercept form:)

Answer:

y = -1/2x + 2

Step-by-step explanation:

Let the equation of the green line be y = mx + c

From the graph, (-6, 5) and (0, 2) are 2 points on the green line.

m = (2-5)/(0-(-6)) = -1/2 (using gradient/slope formula)

sub (0, 2) and m = -1/2:

2 = -1/2(0) + c

2 = c

therefore,

Cara deposited $200 dollars into her savings account bringing her balance up to $450.

Which equation can be used to find, x, the savings account balance before the $200 deposit?

Answers

Answer:

$250 dollars was the original amount of money before she deposited the extra $200 dollars.

Step-by-step explanation:

450 - 200= $220 dollars

220+200= $420 dollars

220+30= $250 dollars

250+200= $450 dollars

$250 dollars is the total amount of money that was originally deposited into her savings account.

Answer:

x + 200 = 450

Step-by-step explanation:

Since clara deposited $200 into her savings account and it brought her account up to $450, to find the answer you would add "x" with 200 and you should get 450 which means x= 250. we can check our answer by solving : 450-200 and you should get 250 for your answer so the answer is

There are 20 squares and 16 triangles. What is the simplest ratio of triangles to total shapes?

Answers

Answer:

4/9

Step-by-step explanation:

20+16= 36 total shapes. 16/36 simplifys to 4/9.

The simplest ratio of triangles to total shapes is 4:7.

Given that the number of squares=20 and the number of triangles=15.

The total number of shapes=20+15=35.

We need to find the simplest ratio of triangles to total shapes.

What is the ratio?

The quantitative relation between two amounts shows the number of times one value contains or is contained within the other.

Now, triangles: total shape=20:35

=4:7

Therefore, the simplest ratio of triangles to total shapes is 4:7.
