Give an example of an equation that has no solution equation and explain why it is a no solution equation.
Answer:
x = x + 7
Step-by-step explanation:
In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.

Solve for m: -8 = m/-10 - 16
Answer:
m = -80
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
-8 = m/-10 - 16
Step 2: Solve for m
Add 16 to both sides: 8 = m/-10Multiply -10 on both sides: -80 = mRewrite: m = -80Answer:
We have this equation:
-8 = m/-10 -1
We can add 8 at both sides:
-8 + 8 = m/-10 -16 + 8
0 = m/-10 -8
Now, we can multiply -8 by -10 with the objective of having the same denominator (-10) in all numbers:
0 = m/-10 - 8*(-10)/-10
0 = m/-10 +80/-10
Now, we can delete all denominators
0 = m + 80
And we can say m = -80
Now, we can replace it to see if it's true:
-80/-10 - 16 = -8, so we know that's true
-80/-10 -16 = 8 - 16 = -8 ..
Michael baked 60 oatmeal cookies and 45 chocolate chip cookies to package in plastic containers for her friends at school. She wants to divide the cookies into identical containers so that each container has the same number of each kind of cookie. If she wants each container to have the greatestnumber of cookies possible, how many plastic containers does she need?
(I really need help)
Answer:
3
Step-by-step explanation:
Michael must find the smallest number possible that can divide 60 and 45 then take the two quotients after dividing the 2 types of cookies by the smallest number possible.
2 is not possible as 45 is an odd number
3 can divide both 60 and 45
60/3 = 20 oatmeal cookies in each container.
45/3 = 15 chocolate chip cookies in each container.

Aubree invested $500 into a mutual fund that paid 3% interest each year compounded annually. Find the value of the mutual fund in 12 years.
Answer:
FV= $712.88
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $500
Number of periods (n)= 12 years
Interest rate (i)= 3% compounded annually
To calculate the future value, we need to use the following formula:
FV= PV*(1+i)^n
FV= 500*(1.03^12)
FV= $712.88

Identify which equations have one solution, infinitely many solutions, or no solution. PLEASE HELP! I will rate the answers!
2.2z+3z=4.5-3.2
2.3y+3.2-y=2.1+1.3y+1.1
2/3x+2/3+1/5x=2/3x
20+4r=32-2r
Answer:
2.3y+3.2-y=2.1+1.3y+1.1
Step-by-step explanation:
The first equation has one solution: z = 0.25.
The second equation has infinitely many solutions.
The third equation has one solution: x = -10/3.
The fourth equation has one solution: r = 2.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
(a) 2.2z+3z=4.5-3.2
Simplifying the left-hand side, we get: 5.2z = 1.3
z = 1.3/5.2 = 0.25
Therefore, the equation has one solution: z = 0.25.
(b)2.3y+3.2-y=2.1+1.3y+1.1
1.3y + 3.2 = 2.2 + 1.3y
Therefore, the equation has infinitely many solutions.
(c) 2/3x+2/3+1/5x=2/3x
Simplifying the left-hand side, we get: 1/5x + 2/3 = 0
1/5x = -2/3
x = -10/3.
(d) 20+4r=32-2r
6r = 12
r = 2
Therefore, the equation has one solution: r = 2.
Hence, The first equation has one solution: z = 0.25.
The second equation has infinitely many solutions.
The third equation has one solution: x = -10/3.
The fourth equation has one solution: r = 2.

If t= 9m,what is the area of the triangle
Help
Answer: the answer
we use the formula 1/2 .b .h
Step-by-step explanation:
the answer is 1,134, we substitute the t to 9 for each number, for example 4(9) 7(9)
4(9)= 36
7(9)=63
now we find the half of our bottom number which is 4=36
1/2 36= 18
so now we have 18x63=1,134
so our answer is 1,134
The area of the triangle is 1134 m²
What is the area of Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
Given data ,
The value of t = 9 m
Let the base of the triangle be b = 4t
= 4 x 9
= 36 m
Let the height of the triangle be h = 7t
= 7 x 9
= 63 m
Now , the area of the triangle = ( 1/2 ) x Length x Base
So , substituting the values , we get
Area of the Triangle = ( 1/2 ) x 36 x 63
= 18 x 63 m²
= 1134 m²
Therefore , the area is 1134 m²
Hence , the area of the triangle is 1134 m²

7x+2=4x+11 ---> subtract 2 to the other side and subtract 4x to the other side
7x-4x=11-2 ---> combine like terms
3x=9 ---> divide by 3
x=3
Answer:
x = 3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
7x + 2 = 4x + 11
Step 2: Solve for x
Subtract 4x on both sides: 3x + 2 = 11Subtract 2 on both sides: 3x = 9Divide 3 on both sides: x = 3Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 7(3) + 2 = 4(3) + 11Multiply: 21 + 2 = 12 + 11Add: 23 = 23Here we see that 23 does indeed equal 23.
∴ x = 3 is the solution to the equation.
