Who knows how to do this I TRULY NEED HELP

Answer:

x=-1

Step-by-step explanation:

3(x−4)=15x

Use the distributive property to multiply 3 by x−4.

3x−12=15x

Subtract 15x from both sides.

3x−12−15x=0

Combine 3x and −15x to get −12x.

−12x−12=0

Add 12 to both sides. Anything plus zero gives itself.

−12x=12

Divide both sides by −12.

x=  

−12

12

​  

Divide 12 by −12 to get −1.

x=−1

Answer:

[tex]3(x- 4)=15x[/tex]

[tex]3x-12=15x[/tex]

[tex]3x-12+12=15x+12[/tex]

[tex]3x=15x+12[/tex]

[tex]3x-15x=15x+12-15x[/tex]

[tex]-12x=12[/tex]

D is the answer

Step-by-step explanation:

A filled circle means "or equal to" in which this case the symbol is less than or equal to, making the dot filled. Since 2 is greater than x, the line would start on the two and continue farther down the line to show that anything 2 or greater is more than x.

Answer:

yes it's on a 1.5 scale factor.....I think. The question you put at the top threw me off at first but the picture makes sense. I'm not entirely sure if this is right but if you adjust the triangle to be the same way as the other one then you will see which sides correspond to each other. Each number can be multiplied by 1.5 to get the number that is on the side of the other triangle that corresponds with it....if that makes any sense

Answer:

Step-by-step explanation:

Number of coins added per day in the collection = 9

Number of coins in the collection after 22 days = 218

To find:

Number of coins in the collection after 36 days.

Solution:

First of all, let us find how many coins did he have initially.

Let the number of coins present initially with Wil = [tex]x[/tex]

Number of coins added per day = 9

Number of coins added after 22 days = 22 [tex]\times[/tex] 9 = 198

Therefore,

[tex]x + 198 = 218\\\Rightarrow x = \bold{20}[/tex]

Number of coins present with Wil initially = 20

Number of coins added after 36 days = 36 [tex]\times[/tex] 9 = 324

Total number of coins after 36 days = Number of coins present initially with Will + Number of coins added = 324 + 20 = 344

The value of the number 2,070,000 written in scientific notation is

A = 2.07 x 10⁶

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as A

Now , the value of A is

A = 2,070,000

Now , to write the number in scientific notation ,

Multiply the number 207 with powers of 10

So , the value of A will be

A = 207 x 10⁴

Now , the number 207 can be written as 2.07 x 10²

On simplifying the equation , we get

A = 2.07 x 10² x 10⁴

A = 2.07 x 10²⁺⁴

A = 2.07 x 10⁶

Therefore , the value of A is 2.07 x 10⁶

Hence , the value of the number is 2.07 x 10⁶

Step-by-step explanation:

Answer:

Step-by-step explanation:

307 divided by 7 is the number of students in each bus with the remainder 6. As the 6 students cannot be fit into the bus and had to travel by car.

Thus we can conclude that:

307= 7x + 6 (6 extra students)

Take away 6 on both sides

7x = 301

i hope this helps i tried my best

x= 43

There are 43 students on each bus.

Answer:

62 people on each bus

Step-by-step explanation:

316-6=310.

310÷5=62 so there will be 62 people riding on each bus.

Answer:

72 / 2 = 36

Step-by-step explanation:

Look at 7 first and figure out how many times 2 will go into 7. 2 will only go into 7 three times. (2 x 3= 6) So put 3 at the top of your division problem and subtract 6 from 7. You should get 1. Then, bring down your 2 to make that one a 12. How many times will 2 go into 12? 6 times. 6 x 2 equals 12 so put 6 at the top of your division problem next to that 3. Subtract your 12 from 12 to get 0. Your final answer would be 36.

Hope this helped!

The division of 72 and 2 is 36.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

The given numbers are 72 and 2.

72 divided by 2

Here, 72/2

Where, 72 is dividend and 2 is divisor.

72/2 = 36

So, quotient is 36

Therefore, the division of 72 and 2 is 36.

Substitute in 11 to get -4+55=18+33. 51=51 is a correct statement.

Answer:

y= -(1/3)x -r

Step-by-step explanation:

a perpendicular line has the slope of the line that it's perpendicular but its the negative reciprocal of it. So for ex: line 1 = 2x then the line perpendicular to it is -1/2x.

In this case, the slope is 3x. The line perpendicular to it therefore, should be -1/3x.

The problem states the line has the same y-intercept so it has to still be -r.

So the equation of the line perpendicular to y=3x-r with the same y-intercept is y=-(1/3)x -r

Answer: SAS

Explanation: There are two sides that are congruent and there is one vertical angle between them which are always congruent.

The measures of unknown angles are, m∠2 is 42°, m∠1 = 88° and

m∠3 = 113°.

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

We know vertically opposite angles are of equal measure.

∴ m∠2 is 42°.

We know the sum of all the interior angles in a triangle is 180°.

∴ m∠1 = 180° - 50° - 42°.

m∠1 = 88°.

m∠3 = 180° - 42° - 25°.

m∠3 = 113°.

We will use the KFC method to figure out the answer:

3/5 ÷ 2/1

We keep the first fraction

3/5 ÷ 2/1

Flip the last fraction (swap the numbers)

3/5 ÷ 1/2

Change the sign (to a multiplication symbol)

3/5 x 1/2

Then, finally, to solve for the answer, we multiply across (3 x 1 and 5 x 2).

3 x 1 = 3

5 x 2 = 10

The answer is 3/10 because it cannot be simplified any further.
