Step-by-step explanation:
The equation 2x + 5 = 3x + 2 represents the cost in dollars, x, of a school lunch. Solve the equation. Write the solution as a whole number or
decimal
The solution of the given equation 2x + 5 = 3x + 2 is 3.
What is the equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
The equation must be constrained with some constraints.
As per the given equation,
2x + 5 = 3x + 2
2x + 5 - 2x = 3x + 2 - 2x
2x - 2x + 5 = 3x - 2x + 2
5 = x + 2
5 - 2 = x + 2 - 2
3 = x
Hence "The solution of the given equation 2x + 5 = 3x + 2 is 3".

Answer:
20m-60 = 280
Step-by-step explanation:
1. Start off defineing a variable, let’s call it m for months.
2. We know that she saves 20$ every month, so we can just divide the total to find the number of months. But, she withdrew $60. We can add those back to get the total she saved. So we have
280 + 60 = 340
Then we can divide by 20:
340/20 = 17.
So the equation would be
20m - 60 = 280.
I hope this helps!
Sarah and Ella were selling boxes of chocolates to raise money for a trip. Sarah sold 5 boxes of chocolates for every 3 boxes Ella sold. Together they sold 160 boxes of chocolates. How many boxes of chocolates did EACH of them sell?
Answer:
Ella sold 100 boxes, and Sarah sold 60 boxes
Step-by-step explanation:
Variables:
Let s be sarah
Let e be ella
Equations:
3e = 5s
s + e = 160 ⇒ s = 160 - e
Work:
3e = 5(160 - e)
3e = 800 - 5e
+5e +5e
8e = 800
e = 100
Ella sold 100 boxes of chocolates.
3(100) = 5s
5s = 300
*divide both sides of the equal sign by 5
s = 60
Sarah sold 60 boxes
The measure of angle H in degrees is?
Answer:
m ∠H = 106°
Step-by-step explanation:
Sum of the angles in a triangle = 180
41° + 33° + ∠H = 180°
74° + m ∠H = 180°
m ∠H = 106°

The perimeter of a square is 44 inches. Find the length of one side
Answer:
11
Step-by-step explanation:
While I square, all the sides of square are the same side, right on the same length. So therefore, um, one side of the square must be equal to well 44 divided by four because they're all the same length. So therefore, one side of the square is just 44 divided by four, which is 11.

The required value of the expression x·y·z is -3/4 which is determined by substituting the values of x, y, and z in the given expression.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
The given expression below is:
⇒ x·y·z
We have to determine the evaluation of the given expression
Here the variables x, y, and, z are given in the question
x = −2/3
y = 0.6
z = 1 7/8 = 15 / 8
⇒ x·y·z
Substitute the values of x, y, and z in the given expression,
⇒ (-2/3)·(0.6)·(15 / 8)
⇒ (-2/3)·(6/10)·(15 / 8)
⇒ - (2×6×15) / (3×10×8)
⇒ - 180 / 240
Reduce the fraction to the simplest form
⇒ - 3 / 4
Thus, the required value of the expression x·y·z is -3/4.

x×cos[tex]\frac{y}{x}[/tex]× (ydx +xdy)= y×sin[tex]\frac{y}{x}[/tex]×(xdy- ydx)
Looks like you're given
x cos(y/x) (y dx + x dy) = y sin(y/x) (x dy - y dx)
Like with your other equation, multiply by 1/x² on both sides:
cos(y/x) (y/x dx + dy) = y/x sin(y/x) (dy - y/x dx)
Then substitute z = y/x again, so y = xz and dy = x dz + z dx. You end up with a separable equation.
cos(z) (z dx + x dz + z dx) = z sin(z) (x dz + z dx - z dx)
cos(z) (2z dx + x dz) = xz sin(z) dz
2z cos(z) dx = x (z sin(z) - cos(z)) dz
(z sin(z) - cos(z)) / (z cos(z)) dz = 2/x dx
(tan(z) - 1/z) dz = 2/x dx
Integrate both sides:
∫(tan(z) - 1/z) dz = ∫ 2/x dx
-ln|cos(z)| - ln|z| = 2 ln|x| + C
ln|cos(z)| + ln|z| = -2 ln|x| + C
ln|z cos(z)| = ln(1/x²) + C
z cos(z) = C/x²
Solve in terms of y :
(y/x) cos(y/x) = C/x²
y cos(y/x) = C/x

Which sentence should Reese add after sentence 18 to provide additional support for the inference in sentence 19?
A)
It would be a good idea to get rid of these bad proteins.
B)
Another type of protein is important to building strong muscles.
C)
Alzheimer's is a disease that is heavily researched
D
Some of these same proteins appear in the waste products of brain cells
Answer:
D. Some of these same protein appear in the waste products of brain cells
Step-by-step explanation:
Sentence 18 is talking about the proteins, that are common in alzheimers as well. Then sentence 19 talks about getting rid of the waste.
Option D is the correct choice because it talks more about the specific proteins and why they can be bad and provides additional support for sentence 19 talking about how to get rid of the waste that these proteins appear in.
