Given the information, we can determine that the cost of the toothbrush is $1.15. To arrive at this, we created an equation based on the given information and solved for the unknown, which in this case is the cost of the toothbrush.
Explanation:If Brooke buys a toothbrush and toothpaste for $2.95, and the toothbrush costs $.65 less than the toothpaste, we have to use the information to solve for the cost of the toothbrush.
Let's define the cost of the toothpaste as x. Therefore, the cost of the toothbrush would be x - $0.65 (since the toothbrush costs $0.65 less than the toothpaste).
The combined cost of the toothbrush and toothpaste is $2.95, so we can set up the equation: x + (x - $0.65) = $2.95
If we simplify and solve this equation, we get x = $1.80. That's the cost of the toothpaste. The cost of the toothbrush would therefore be $1.80 - $0.65 = $1.15.
So, the toothbrush costs $1.15.

What is the coefficient in the expression 3x/13+4?
The coefficient is the multiplication constant with a variable thus in the expression 3x/13 + 4 the number 3/13 will be the coefficient.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
It is known that the coefficient is the constant which is in multiplication with a variable.
In general, variables are represented by x,y, and z.
The given expression is 3x/13 + 4.
Here,x is a variable therefore the term 3/13 will be a coefficient.
Hence "The coefficient is the multiplication constant with a variable thus in the expression 3x/13 + 4 the number 3/13 will be the coefficient".

What is the area of the triangle in the diagram?
Answer:
Option A is the answer.
Step-by-step explanation:
The area of the triangle is given as :
[tex]A=\frac{1}{2}\times base\times height[/tex]
Base will be given by :
[tex]\sqrt{(x1-0)^{2}+(y1-0)^{2}}[/tex]
= [tex]\sqrt{x1^{2}+y1^{2}}[/tex]
Similarly the height will be given by:
[tex]\sqrt{(x2-0)^{2}+(y2-0)^{2}}[/tex]
= [tex]\sqrt{x2^{2}+y2^{2}}[/tex]
Now, putting these dimensions in the formula we get:
[tex]\frac{1}{2}\times \sqrt{(x1^{2}+y1^{2})(x2^{2}+y2^{2})}[/tex]
Therefore, option A is the answer.

What is 4 7/8 as a improper fraction
Suppose point e has a coordinate of 11, and eg= 8. what are the possible coordinates of point g?
So I will be assuming that EG = 8 is the length of the line segment EG. If that's the case, therefore the coordinates of G would simple be:
G =11 ± 8
G = 11 – 8, 11 + 8
G = 3, 19
So G can have a coordinate of 3 or 19.

A problem states: " there are 3 more baseballs than bats in a dugout. There are 15 bats and baseballs in the dugout in all. How many bats are in the dugout?" Let b represent the number of bats. Which expression represents the situation?
Answer:
The required equation is 2b+3=15.
Number of bats = 6
Number of baseballs = 9
Step-by-step explanation:
Let b be the number of bats.
It is given that there are 3 more baseballs than bats in a dugout.
Number of baseballs = b + 3
Number of bats and baseballs in the dugout in all is
[tex]Total=b+(b+3)[/tex]
[tex]Total=(b+b)+3[/tex]
[tex]Total=2b+3[/tex]
There are 15 bats and baseballs in the dugout in all.
[tex]2b+3=15[/tex]
The required equation is 2b+3=15.
Subtract 3 from both sides.
[tex]2b=15-3[/tex]
[tex]2b=12[/tex]
Divide both sides by 2.
[tex]b=6[/tex]
The value of b is 6. So, the number of bats is 6 and number of baseballs is 6+3=9.

True or False
The sum of two trinomials is ALWAYS a trinomial
Answer:
True.
Step-by-step explanation:
If the two trinomials are given as
x³ + 2x² + 4 = 0
and
2x³ + x² - 3 = 0
Then by adding these trinomials we get
(x³ + 2x² + 4) + (2x³ + x² - 3) = 0
3x³ + 3x² + 1 = 0
Which proves that sum of two trinomials is ALWAYS a trinomial.
So the answer is True.
explain how ray ab an ac form both a line and an angle
Answer:
Rays AB and AC both have a point in common. That is the A point or normally called the vertex. From the point both go in different directions making a distance between both. This distance has a degree in which it separated that forms the angle. This also forms a line because both rays, in theory, are lines. They just tend to continue to infinity in just one direction.

If angleA and angleB are vertical angles, and angleA = 38°, find the measure of angleB. A. B = 7° B. B = 57° C. B = 38° D. B = 142°
Answer:
C. B = 38°
Step-by-step explanation:
A vertical angle is created when two lines intersect, and are a pair of two non adjacent angles that are opposite from the origin, so both angles are going to measure the same.
Since both vertical angles are the same, both measure 38º.
Vertical angles are shown in the image:In this case the angle A would be the omega, and the B is the alfa.

What conjecture can you make about the twentieth term in the pattern A, B, A, C, A, B, A, C?
Answer:
c
Step-by-step explanation:
ABACABACABACABACABAC
The pattern A, B, A, C repeats every four terms. Dividing the term number (20) by the length of the repeating sequence (4) yields 5 with no remainder, indicating the twentieth term will be the same as the fourth term - which is 'C'.
Explanation:The given pattern A, B, A, C, A, B, A, C is a repeating sequence that occurs in sets of four (A, B, A, C). To ascertain the twentieth term in this pattern, divide the term number by the length of the repeating sequence. That would be 20 divided by 4, which equals 5 with no remainder. That suggests the twentieth term will be the same as the fourth term in the sequence, which is C.
