Algebraic expression for each statement in terms of w would be:

Each pencil will cost: w/5.

A pen will cost: w/5 + 0.35

Number of pencils 20 dollars will buy = w/5 = 20/5 =4 pencils.

Algebraic expression in mathematics is an expression that is made up of variables, constant, and mathematical symbols, which can be used to represent a statement.

Thus:

Let w represents the price for 5 pencils.

Each pencil will cost: w/5.

A pen will cost: w/5 + 0.35

a. cost in dollars for a pen = w/5 + 0.35

b. Number of pencils 20 dollars will buy = w/5 = 20/5 =4 pencils.

[tex]\sqrt{49}[/tex]

Step-by-step explanation:

[tex]\sqrt{49} =7[/tex]

The square root of 49, which is the greatest perfect square that is less than 55.

A perfect square that is the nearest, greater perfect square to [tex]\sqrt{49}[/tex] is [tex]\sqrt{64}[/tex].

There are no other perfect squares in between [tex]\sqrt{49}[/tex] and [tex]\sqrt{64}[/tex] there are only decimals.

Therefore, [tex]\sqrt{49}[/tex] is your answer.

Proof:

[tex]7^{2} =49[/tex]

[tex]8^{2}=64[/tex]

Answer:

b = 35

Step-by-step explanation:

Use the butterfly method (Cross multiply):

b × 13 = 13b

65 × 7 = 455

So you would have:

13b = 455

Divide both sides by 13.

You will get b = 35

Hope this helps!

Answer: b=35

Step-by-step explanation:

[tex]\frac{b}{65}=\frac{7}{13}[/tex]

Multiply both sides by 65:

[tex]\frac{65b}{65}=\frac{7\cdot \:65}{13}[/tex]

[tex]b=35[/tex]

Inequality Form: g ≤ −2

Step-by-step explanation:

Answer: 2

Step by step: I start with a long-division set-up

Looking only at the leading terms, I divide 3x3 by 3x to get x2. This is what I put on top:

x^2 up on top

I multiply this x2 by the 3x + 1 to get 3x3 + 1x2, which I put underneath:

3x^3 + 3x put down underneath the dividend

Then I change the signs, add down, and remember to carry down the "+10x – 3" from the original dividend, giving me a new bottom line of –6x2 + 10x – 3:

(3x^3 – 5x^2 + 10x – 3) – (3x^3 + 1x^2) = –6x^2 + 10x – 3

Dividing the new leading term, –6x2, by the divisor's leading term, 3x, I get –2x, so I put this on top:

(–6x^2) ÷ (3x) = –2x, which goes on top

Then I multiply –2x by 3x + 1 to get –6x2 – 2x, which I put underneath. I change signs, add down, and remember to carry down the "–3 from the dividend:

(–6x^2 + 10x –3) – (–6x^2 – 2x) = 12x – 3, which is my new last line

My new last line is "12x – 3. Dividing the new leading term of 12x by the divisor's leading term of 3x, I get +4, which I put on top. I multiply 4 by 3x + 1 to get 12x + 4. I switch signs and add down. I end up with a remainder of –7:

(12x)/(3x) = 4, 4(3x + 1) = 12x + 4, (12x – 3) – (12x + 4) = –7

This division did not come out even. What am I supposed to do with the remainder?

Think back to when you did long division with plain numbers. Sometimes there would be a remainder; for instance, if you divide 132 by 5:

132 ÷ 5: 2 × 5 = 10; put 2 on top and 10 underneath; 13 – 10 = 3; new divisor is 32; 6 × 5 = 30; put 6 on top and 30 underneath; 32 – 30 = 2; answer is 26 with remainder 2

...there is a remainder of 2. Remember how you handled that? You made a fraction, putting the remainder on top of the divisor, and wrote the answer as "twenty-six and two-fifths":

\dfrac{132}{5} = 26\,\dfrac{2}{5} = 26 + \dfrac{2}{5}

5

132

​

=26

5

2

​

=26+

5

2

​

The first form, without the "plus" in the middle, is how "mixed numbers" are written, but the meaning of the mixed number is actually the form with the addition.

We do the same thing with polynomial division. Since the remainder in this case is –7 and since the divisor is 3x + 1, then I'll turn the remainder into a fraction (the remainder divided by the original divisor), and add this fraction to the polynomial across the top of the division symbol. Then my answer is this:

\mathbf{\color{purple}{\mathit{x}^2 - 2\mathit{x} + 4 + \dfrac{-7}{3\mathit{x} + 1}}}x

−2x+4+

3x+1

Answer:

No

Step-by-step explanation:

To check if 2 expressions are equal to each other you can set them equal to each other. If, after you simplify, the equation is true, then they are equal. If it is not, then the expressions are not equal.

3(4x-2)=12x-2

12x-6=12x-2

12x=12x+4

0=4

The statement 0=4 is not true. This means that the expressions are not equal.

each tomato=4

7-4=3 so each avocado is 3

5-3=2 so each lime is two

so 4+2=6

Answer:

Step-by-step explanation:

Tomato + tomato = 8  ⇒  tomato = 4

Avocado + tomato = 7 ⇒  Avocado = 7 - 4 = 3

Avocado + Lemon = 5  ⇒  Lemon = 5 - 3 = 2

Therefore, Lemon + tomato = 2 + 4 = 6
