Solve for y 2x+5y=10

Answer:

0

Step-by-step explanation:

First, you have 3x and subtract 18x from it. This gives you -15x.

Then you have positive 26x, so you add 26x onto -15x.

After doing so, you have a positive 11x.

Now you need to subtract 11x from 11x.

Your final answer is 0! (No need to put x since it is just zero.)

Answer:

154+2x=360

Step-by-step explanation:

Since the opposite angles are the same you add them together getting 154. You now have two unknown angles that are congruent which is expressed as 2x, and since a four sided shape always has an interior angle of 360 you set it equal. This gives you 154+2x=360.

Answer: It is the last one

154 + 2x = 360

Step-by-step explanation:

x= 103

154 + 2(103)= 360

154 + 206 =360

[tex]7 \leq x \leq 9[/tex]

Step-by-step explanation:

Let [tex]x[/tex] represent the real numbers.

For the first part, all real numbers less than or equal to 9 in algebra is [tex]x \leq 9[/tex].

For the second part, all real numbers greater than or equal to 7 in algebra is [tex]x \geq 7[/tex].

To combine both inequalities, it would become [tex]7 \leq x \leq 9[/tex].

Hope this helped! If not, please let me know! <3

The real numbers are 7, 8, and 9.

We are given two statements:

We have to use these two statements, form an inequality for the real number and find the real numbers.

Inequality is a relation that makes a non-equal comparison between two mathematical expressions.

There are five types of inequality:

[tex]Less~~than~ = ~ < \\Greater~~than~=~ > \\Less~~than~~or~~equal~~to~=~\le\\Greater~~than~~or~~equal~~to~=~\ge[/tex]

Let the real number be x.

Now using the two given statements we have,

[tex]x\le9\\x\ge7[/tex]

If we combine these two equations we get,

[tex]7\le x \le 9[/tex]

Thus we can say that the real numbers are 7, 8, and 9.

Answer:

[tex]x^3-3x^2-10x+24[/tex]

Step-by-step explanation:

The first thing that you have to do is take the roots that you're given and write binomial products.

[tex]x= 2, -3, 4[/tex]

[tex](x-2)(x+3)(x-4)[/tex]

Remember that a root is the value of "x" in a binomial expression, so the binomial expression itself will have the opposite sign of the root.

The next thing you have to do is multiply the roots together. A good way to do this is the "box method."

(See attachment below for the multiplication of [tex](x-2)[/tex] and [tex]x+3[/tex]. )

Next, multiply your new trinomial by your remaining binomial. (See additional attachment below for the multiplication of [tex](x^2+x-6)[/tex] and [tex](x-4)[/tex])

The resulting polynomial is [tex]x^3-3x^2-10x+24[/tex].

Step-by-step explanation:

Here is the remaining part of the question :

The amount of the tax on a case of cola is per case. Of this amount, the burden that falls on consumers is per case, and the burden that falls on producers is per case. True or False: The effect of the tax on the quantity sold would have been larger if the tax had been levied on consumers. True False

A tax is a compulsory sum levied by the government or an agency of the government on goods or services.

Tax on a case of cola = Amount consumers pay - amount producers receive

= $5 - $2 = $3

Burden of tax on consumers = $5 - $4 = $1

Burden that falls on producers = $3 - $1 = $2

False. the incidence of tax is not dependent on who is taxed

Answer:

1. 1.96 g/L

2. 1 g/cm³

Step-by-step explanation:

Density is found by dividing mass by volume: d = m/v.

1.

We know that the mass is 0.196 grams, while the volume is 100 mL.

Converting the volume to liters, we get:

100 mL = 0.1 L

Then, applying our density formula:

d = m/v

d = 0.196 g / 0.1 L = 1.96 g/L

2.

Here, we know that the mass is 27 grams. However, we don't know the volume, which we need to find.

The block of wood is 3 cm on all sides, which means it's a cube. The volume of a cube is denoted by V = s³, where s is the side length. Here, s = 3, so V = s³ = 3³ = 27 cm³.

Applying our density formula gives:

d = m/v

d = 27 g / 27 cm³ = 1 g/cm³

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

First I would distribute what I can...

[tex]6(2x+4)2=(2x+4)+2\\24x+48=2x+4+2[/tex]

Now we combine like terms...

[tex]24x+48=2x+6[/tex]

Subtract 2x from both sides...

[tex]22x+48=6[/tex]

Subtract 48 from both sides...

[tex]22x=-42[/tex]

Divide both sides by 22...

[tex]x=-\frac{21}{11}[/tex]

So the answer is [tex]-\frac{21}{11}[/tex]

Answer:

17in, 49in, 35in

Step-by-step explanation:

I did this in my RSM homwork and it is correct.

First, I added the two inches shorter to the 101, then subtracted 1 longer and got 102.

then divide 102 by how many second lengths, 6. so 102 ÷ 6 = 17

17 is the second length.

3x17-2=49 (another length)

2x17+1=35 (last length)

and there is your answer!

First side : 49

Second side : 17

Third side : 35

If triangle has sides a, b, c , then the perimeter of that triangle will be P= a +b +c.

Now, according to the question

Let  second side be (b) = x unit

then, First side will be  (a)= 3x-2 unit

and Third side will be  (c)= 2x + 1 unit

since , perimeter is 101

P = a + b + c

x + 3x -2 + 2x + 1 = 101

6x - 1 = 101

x= 17

hence , b = 17 unit

a= 3*17 - 2 =49 unit

c = 2*17 +1 = 35 unit
