If Myesha found 6 nickels and 12 quarters under her cushion, this means that she has a total of 18 coins.
What is an equation?An equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the number of nickels and y represent the number of quarters. There are 2 cups in 1 pint. Hence:
If she has 6 nickels and 12 quarters:
Number of coins = 12 + 6 = 18
If she has x nickels and y quarters:
Number of coins = x + y
If Myesha has 6 nickels and 12 quarters, this means that she has 18 coins.

What are the values of a 1 and r of the geometric series? 1 3 9 27 81 a 1 = 1 and r = one-third a 1 = one-third and r = 1 a 1 = 1 and r = 3 a 1 = 3 and r = 1.
Answer:
a₁ = 1
r = 3
Step-by-step explanation:
Since it’s a geometric series then
a₁ = 1 ( because 1 is the first term of the series)
3/1 = 9/3 = 27/9 = 81/27 = 3 then r=3.

Step-by-step explanation:
D and E are right.
==================================================
Explanation:
The domain is the set of all real numbers because we can replace x with any real number we want to get some y output. There isn't any restriction on x. We don't have to worry about dividing by zero for instance. This is why choice A is one of the answers.
The range is restricted however. The largest value we can make in the range is y = 0. The graph of y = -4x^2 shows a parabola that opens upside down. The highest point is at (0,0). So that's why choice D is the other answer.
---------------------------
Extra info:
Choice B is false because we can get outputs like y = -3, y = -2, y = -1, or y = 0.Choice C is false. A parabola has one half increasing, and the other half decreasing.Choice E is false since there is only one x intercept and it happens at (0,0) in this case. This is also the location of the y intercept as well. See the graph below.Find the X and Y values

Simplify 4x + 8 + 2x - 7
Answer:
6x+1
Step-by-step explanation:
Answer:
6x+1
Step-by-step explanation:
Hi there!
We are given the following expression:
4x + 8 + 2x - 7
And we want to simplify
When we simplify, we want to combine like terms. This means that we want to add terms with the same variables together (like x), and then combine them
If there is no variable, then we add and combine the terms that don't have any variable together as well
Please note that we cannot combine terms with different variables (so if you had x+y, then it would stay as x+y).
In this case, we have 4x + 8 + 2x - 7
4x and 2x are like terms; they have the same variable (x). If we add them together, the result is 6x
8 and -7 are also like terms; they both don't have a variable. If we add (or rather, subtract) these terms, the result is 1.
Now we add 6x and 1 together, which would be 6x+1 (1 doesn't have a variable after it, so we can't combine it with 6x).
6x+1 is our answer.
Hope this helps!

A rectangle has an area of 36 square units.
Which of the following could NOT be the
dimensions of the rectangle?
a) 4 inches by 8 inches
b) 2 inches by 18 inches
c) 3 inches by 12 inches
d) 9 inches by 4 inches
Answer:
9 inches and 4 inches
Answer:
Option A
Step-by-step explanation:
Given the following question:
[tex]A=w\times h[/tex]
To find the answer we substitute the values of each option in till we find the answer that doesn't equal 36 square units, since the question already gives us the area of the rectangle.
Option A:
[tex]A=w\times h[/tex]
[tex]A=4\times8[/tex]
[tex]4\times8=32[/tex]
[tex]=32[/tex]
[tex]32 > 36[/tex]
Your answer is option A or "4 inches by 8 inches."

Part A: 50/100+3/100=x/100
Part B: Emma mistook 50/100 for 5/100 when she added it to 3/100. The correct sum would be 53/100
Answer:
Problem A:
5/10 + 3/100 = ?
Example:
Jake bought a cake. On Monday he ate 5/10 of the cake, he then put it in the fridge to store for later. On Wednesday Jake was looking through the fridge for a snack when he came across his leftover cake. His stomach was a bit small though so he only ate 3/100 of his cake. If Jake wants to finish the cake on Friday how much of the cake does he have to eat?
Problem B:
Emma added the value of 3/100 to 5/100 which is incorrect. The first graph is 5/10 or 1/2. The true value would be; 5/10 + 3/100 = 53/100. In conclusion, your answer would be 53/100 for problem B.
