A bag contains 18 coins consisting of quarters and dimes. The total value of the coins is $2.85. Which system of equations can be used to determine the number of quarters, q, and the number of dimes, d, in the bag?
A. 0.10q+0.25d=2.85
q+d=18
B. 0.10q+0.25d=18
q+d=2.85
C. 0.25q+0.10d=2.85
q+d=18
D. 0.25q+0.10d=18
q+d=2.85
Answer: A. 0.10q+0.25d=2.85
q+d=18
Step-by-step explanation:
The system of equations can be used to determine the number of quarters, q, and the number of dimes, d, in the bag is q+d=18 and 0.25q+0.10d=2.85.
Given that, a bag contains 18 coins consisting of quarters and dimes. The total value of the coins is $2.85.
We need to find which system of equations can be used to determine the number of quarters, q, and the number of dimes, d, in the bag.
What is the system of equations?In algebra, a system of equations comprises two or more equations and seeks common solutions to the equations. "A system of linear equations is a set of equations which are satisfied by the same set of variables."
The number of quarters, q, and the number of dimes, d, in the bag.
Now, the number of quarters + the number of dimes=18
⇒q+d=18
The total value of the coins is $2.85.
So, 0.25q+0.10d=2.85
Therefore, the system of equations can be used to determine the number of quarters, q, and the number of dimes, d, in the bag is q+d=18 and 0.25q+0.10d=2.85.

Which function is equivalent to h(x)=10x2+9x-1?
A. h(x)=(x-1)(10x+1)
B. h(x)=(x+1)(10x-1)
C. h(x)=(10x+1)(x+1)
D. h(x)=(10x-1)(x-1)
Answer:
i think the answer is c
Step-by-step explanation:
The equivalent function is [tex]h(x)=(x+1)(10x-1)[/tex]option B is correct.
Important information:
The given function is [tex]h(x)=10x^2+9x-1[/tex].We need to find the equivalent function.
Equivalent expression or function:The given function can be written as:
[tex]h(x)=10x^2+10x-x-1[/tex]
[tex]h(x)=10x(x+1)-1(x+1)[/tex]
[tex]h(x)=(10x-1)(x+1)[/tex]

Adriana bought a computer and three pieces of software. She spent a total of $1,220. The computer cost $995, and each piece of software costs the same price. Write and solve the equation needed to answer this question
Arrange the systems of equations that have a single solution in increasing order of the x-values in their solutions. 2x + y = 10 x − 3y = -2 x + 2y = 5 2x + y = 4 x + 3y = 5 6x − y = 11 2x + y = 10 -6x − 3y = -2
Answer: IN ORDER
x + 2y = 5
2x + y = 4
This equation equals to x = 1 and y = 2
x + 3y = 5
6x - y = 11
This equation equals to x = 2 and y = 1
2x + y = 10
x - 3y = -2
This equation equals to x = 4 and y = 2
Step-by-step explanation:
It obvously cannot be:
2x + y = 10
-6x - 3y = -2
Because this equation has NO SOLUTION.

Consider rectangle WXYZ with diagonal XZ. Rectangle W X Y Z is cut diagonally into 2 equal triangles. Angle Y X Z is 26 degrees and angle X Z W is x degrees. Angles Y and W are right angles. The angle relationship for triangle XYZ is 26° + 90° + m∠YZX = 180°. Therefore, m∠YZX = 64°. Also, m∠YZX + m∠WZX = 90°. So, x = °.
Answer:
26 i think
Step-by-step explanation:
next time try upload a picture so it for easier for us to answer
The measure of x is 26°.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
Given a rectangle WXYZ.
The diagonal XZ divides the rectangle into two triangles.
Consider ΔXYZ.
Sum of interior angles of a triangle is 180°.
26° + 90° + m ∠YZX = 180°
m ∠YZX = 180 - (26 + 90)
= 64°
Angle Z is a right angle.
m ∠YZX + m ∠WZX = 90°
64 + x = 90°
x = 26°
Hence the measure of angle x is 26°.

=
Answer:
the answer would be done like this
Step-by-step explanation:
you have to get y by itself so you would need to move the x to the right of the equal sign
once you move anything to the opposite side it switches, so positive becomes negative vice versa
-3y=-x+18
you need to make sure you have positive 1 y so you would divide y by -3 to make it 1
everything else is multiplied by -3 as well
so the answer would be y=⅓x-6

A paper popcorn cone measures 4 inches in diameter and is 9 inches high. What is the volume of popcorn that can be contained within this cone? Use 3.14 for pi. Round your answer to the nearest hundredth.
answer choices
41.90 cubic inches
37.68 cubic inches
39.45 cubic inches
40.23 cubic inches
Answer:
The formula for finding volume of a cone is (in this case),
V=(3.14)(r^2)(h/3)
With this formula in mind, you would simply substitute in.
V=(3.14)(2^2)(9/3)
You could work that out for yourself on your own, but to save you the time, it is 37.68 in. cubed.
