Write the difference between verbal expression and algebraic expressions?Verbal expressions are sentences that express a mathematical concept or equation. They use words, such as "twice the number," "the product of," or "sum of," as opposed to symbols and operations. Verbal expressions are often used to explain math problems or to pose questions.Algebraic expressions, on the other hand, use symbols and operations to express mathematical concepts. Symbols such as +, -, x, and / can be used to represent addition, subtraction, multiplication and division, respectively. Algebraic expressions are also used to simplify equations and can be used to solve math problems. For example, an algebraic expression such as "2x + 3y" can represent the sum of two numbers multiplied by two and three, respectively.The main difference between verbal expressions and algebraic expressions is that verbal expressions use words to explain a mathematical concept while algebraic expressions use symbols and operations. Verbal expressions are often used to explain a problem while algebraic expressions are used to solve the problem.To learn more about algebraic expressions refer to:

What is the solution of the system of equations y =- 2x 8 y x 4?
Answers
The solution of the system of equations y =0 x=4
To solve the system of equations, we must set the two equations equal to each other and solve for x.
y = -2x + 8
y = x - 4
We start by subtracting the second equation from the first equation.
-2x + 8 = (x - 4)
We then add 4 to both sides of the equation.
-2x + 12 = x
We then subtract 12 from both sides of the equation.
-3x = -12
Finally, we divide both sides of the equation by -3.
x = 4
Now that we have solved for x, we can substitute 6 for x in either equation and solve for y.
y = -2(4) + 8
y = -8 + 8
y = 0
Therefore, the solution of the system of equations is (4, 0).

e.
A reasonable range is [0, 20].
Answers
The true statement about the function in the list of options is (d) none of these
How to determine the true statements in the list of optionsFrom the question, we have the following parameters that can be used in our computation:
p c
0.25 1.69
0.45 3.04
0.75 5.06
1.25 11.81
Where
the number of pounds of candy = p the cost of candy = cThe values in the p column represent the domain
In this case, the domain is
Domain = [0.25, 1.25]
The values in the c column represent the range
In this case, the range is
Range = [1.69, 11.81]
This means that the options (a), (b) and (e) are false
For option (c), we have
c = 6.75p
This means that
c = 6.75 * 0.25 = 1.69
c = 6.75 * 0.45 = 3.04
c = 6.75 * 0.75 = 5.06
c = 6.75 * 1.25 = 8.43 -- false
This means that the option (d) is false
Hence, none of the options is true

All that is the equivalent angle to the given angle sin∠GFH is cos∠GEJ.
Corresponding angles are those angles which are created in the matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line (i.e. the transversal).
From the image, we get JE and HF are parallel.
So ∠GFH and ∠GEJ are corresponding angles. That means they are equal.
⇒sin(∠GFH) = sin(∠GEJ).
From triangle GFH, ∠GFH + ∠FGH = 90.
⇒sin(∠GFH) = cos(∠FGH).
Again ∠FGH = ∠EGJ.
⇒sin(∠GFH) = cos(∠EGJ)
All that is equivalent to sin∠GFH is cos(∠EGJ).

A loan of $9,000 has an annual simple interest rate of 3.5%. What would be the simple interest rate if a loan of $9,000 that is repaid in 6 years has a total cost of $11,052?
Answers
Answer: 3.8%
Step-by-step explanation:
First find the interest cost:
= Amount repaid - Amount borrowed
= 11,052 - 9,000
= $2,052
This cost is the simple interest and because it is the same figure per year, the annual simple interest can be determined by dividing the above by the number of years:
= 2,052 / 6
= $342
Now that we have the simple interest amount, divide it by the amount borrowed to find the rate:
= 342 / 9,000
= 3.8%

Delaney would like to make a 5 lb nut mixture that is 60% peanuts and 40% almonds. She has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds. Let p represent the number of pounds of peanuts needed to make the new mixture, and let m represent the number of pounds of the 80% almond-20% peanut mixture.
What is the system that models this situation?
Which of the following is a solution to the system: 2 lb peanuts and 3 lb mixture; 2.5 lb peanuts and 2.5 lb mixture; 4 lb peanuts and 1 lb mixture? Show your work.
Answers
Answer:
p + m = 5, p + 0.2m = 0.6(5)2.5 lb peanuts; 2.5 lb almond mixStep-by-step explanation:
You have peanuts and an 80-20 almond-peanut mix, and you want to know how many pound of each are needed for 5 lb of a 60% peanut mix.
System of equationsThe system of equations relating the pounds of peanuts (p) and the pounds of almond mix (m) will describe the total mixture weight, and the weight of the peanuts.
p + m = 5 . . . . . . total mixture weight is 5 lb
p + 0.20m = 0.60(5) . . . . . weight of peanuts in the 60% peanut mix
SolutionWe can subtract the second equation from the first to eliminate the variable p:
(p +m) -(p +.2m) = (5) -(.6)(5)
0.8m = 0.4(5) . . . simplify
m = 2.5 . . . . . . . . divide by 0.8
p = 5 -m = 2.5
The solution to the system is 2.5 lb peanuts and 2.5 lb mixture.

1,000 yards to kilometers
Answers
1000 yards in kilometers will be 0.9 km.
The yard is a United States customary measurement. In this form of measurement, we have yards, feet, and inches.
1 Yard = 3 feet.
1 foot = 12 inches.
Here we are given 1000 yards,
1000 yards = 3 X 1000 feet
= 3000 feet
= 36000 inches.
Now, converting this to the metric measures we know that
1 inch = 2.5 cm
Hence, 36000 inches = 90000 cm.
1 cm = 1/100 m
Hence, 90000 cm = 90000/100 m
= 900 m
1 m = 1/1000 km
Hence, 900 m = 900/1000 km
= 0.9 km
Hence, 1000 yeard = 0.9 km.

Answers
The total cost of the bill that sells for $42 is $54.0204
How to determine the total cost of the bill?From the question, we have the following parameters that can be used in our computation:
Cost of the bill = $42
Sales tax = 9%
Tip = 18%
The total cost of the bill that sells for $42 is then calculated as
Total cost = Selling price * (1 + Sales tax) * (1 + tip)
Substitute the known values in the above equation, so, we have the following representation
Total cost = 42 * (1 + 9%) * (1 + 18%)

Answers
2a+b=15.7 is the formula used to get the base's length and b has a value of 3.
What is an isosceles triangle?Therefore, an isosceles triangle has two equal sides as well as two equal angles. The Greek words iso (same) and Skelos are the source of the name (leg). An equilateral triangle is one in which all of its sides are equal, whereas a scalene triangle is one in which none of its sides are equal.
An isosceles triangle has 2 equal sides that are longer than the length of the base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 identical sides
2(6.3) + b = 15.7
12.6 + b = 15.7
subtract 12.6 from both sides
b = 3.1
