Ms. Wilson bought 5 pencils for w dollars. Each pen costs 35 cents more than a pencil.
Enter an algebraic expression for each statement in terms of w in the boxes.
a) The cost, in dollars, of a pen. $
b) The number of pencils that Ms. Wilson can buy with 20 dollars.
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.
What is an Algebraic Expression?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.

Please help! Urgent!
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.
So, set up the equation3(4x-2)=12x-2
Then, distribute the 3 to 4x and 212x-6=12x-2
From this point, you can probably tell that they will not be equal. But, if you wanted to continue, the next step would be to add 6 to both sides12x=12x+4
Then, subtract 12x from both sides0=4
The statement 0=4 is not true. This means that the expressions are not equal.

Step-by-step explanation:
each tomato=4
7-4=3 so each avocado is 3
5-3=2 so each lime is two
so 4+2=6
Answer:
6
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

Find the equation of the straight line which cuts off intercepts -5 and 3 on X-axis and Y-axis respectively.
By using the concept of equation of a Straight line,we arrive to the conclusion that the equation of the straight line which cuts off intercepts -5 and 3 on X-axis and Y-axis respectively is 5x - 3y + 15 = 0.
Interception is the point where any line or curve crosses the axis.If the point of crossing line in x-axis then it is known as x-intercept .Similarly, if the point lies on y-axis is is named as y-intercept.
Here,according to the quesion:
x-intercept of the line is,a= -5
y-intercept of the line is,b= 3
The equation of the line here by formed with intercepts is:
[tex]x/a +y/b =1[/tex]
therefore x/(-5) + y/3 =1
- 5x+3y = 15
5x -3y+ 15=0
So,the equation of the mention line is 5x -3y+ 15=0

A 1/2 cup serving of ice cream contains 140 calories. How many calories would be in a 1 1/2 cup serving?
Answer:
420 calories is your answer.
Step-by-step explanation:
If half of it is 140 we know that the other half is 140, so the full thing of ice cream is 380. So 1 cup is 380, and half is 140. 380+140 = 420. So 1 1/2 = 420 calories. Could i get brainliest :D
A swimming is filled at a constant rate.when half full the pool had 7500 litres poured into it.a) what fraction has still to be put into the pool?b)How much water will be needed when 5000 litres is already in the pool?
Answer:
A. 1/2 has still to be put in the pool, if we already have 7500 litres in the pool and that's half we need 7500 more which is another half.
B. if 7500 is half the amount that can fit in the pool it means that when the pool is full there are 15000 litres of liquid in the pool meaning that if there is barely 5000 litres we are barely 1/3 of the way done. but if the question is asking if we add 5000 to the 7500 already in the pool we will have 12500 out of the 15000 required to fill the pool, this fraction simplified would be 5/6

what is 6x cubed divided by 2x
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
