Answer:
Step-by-step explanation:
For correct questions
1 correct questions = 1 3/4 points
1 correct question = 7/4 points
Since he got 58correct questions, tgw total points he earned will be;
58 × 7/4
= 406/4
= 101.5points
For incorrect questions
1 incorrect question = -14points
22 incorrect = -14×22
22incorreft = -308points
Total points gained/lost =-308+101.5
Total points lost = -206.5
Since Nevan has a negative point of -206.5, this means that he lost.
He scored -206.5points

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that April and bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars and 3 large chocolate bars. April paid $16.50 and bill paid $11.25.
We can write -
4x + 6y = 16.50 ... Eq{ 1 }
3x = 11.25 ... Eq{ 2 }
On solving the equation, we get -
{x} = 11.25/3
{x} = 3.75
Now, we can write -
4x + 6y = 16.50
4 x 3.75 + 6y = 16.50
6y = 16.5 - 15
6y = 1.5
y = 1.5/6
{y} = 0.25
Therefore, the cost of a large single chocolate is $0.25.

Under very specific instructions, a jeweler made one ring for the queen and one ring for the princess. The gem on the queen's ring weighed 9/10 of a carat and the stone on the princess's ring weighed 7/10 of a carat. How much heavier was the stone on the queen's ring than the stone on the princess's?
Answer: 1/5
Step-by-step explanation:
From the question, we are informed that the gem on the queen's ring weighed 9/10 of a carat and the stone on the princess's ring weighed 7/10 of a carat.
To calculate how heavier the stone on the queen's ring was than the stone on the princess will be:
= 9/10 - 7/10
= 2/10
= 1/5
Adan works as an information technician and fitness trainer. As a technician, he earns $22 per hour. Last week he worked x hours as a technician and his friend paid him $50 for a day of fitness training. Write an expression to represent the total amount Adan earned last week.
Answer: t = 22x + 50
Step-by-step explanation:
t = total amount earned
x = hours worked
We know his friend payed $50, so that is our initial value. We don’t need hours for that one.
For his job as trainer, he earns $22 per hour but we don’t know how many hours he earned, so that is x. That is how I got the 22x.
Hope this helps! And of course, feel free to use any variables of your choice. :)
A dad has three sons. He shares an amount of $30,000 among his three sons. One son deposited his amount in a bank that provides him interest at the rate of 7%. The second son deposited his sum in a mutual fund that gave him returns at a rate of 8%. The third son invested his in another bank that provided him an interest rate of 6%. The second sons share is 1000 more than that of the third son. The total interest that they got was $2110. Calculate each person's share if the first sons share is equal the second son and the third son put together.
Answer:
First son receives $15000
Second son receives $8000
Third son receives $7000.
Step-by-step explanation:
Let first son receive $x and deposit it at 7%
Second son receive $y and deposit in 8%
Third son receive $z and deposit in 6%
Now, let's set up equation using the given information.
The second son share is 1000 more than the third son.
So, we can set up equation as
y= 1000+z
First son share is equal the second son and the third son put together.
So, x=y+z
And we can set up equation for total 30000 as
x+y+z=30000
Plug in y as 1000+z and x as y+z
We get third equation as
y+z+1000+z+z=30000
Plug in again y as 1000+z
It gives,
1000+z+z+1000+z+z=30000
Combine like terms,
2000+4z=30000
Subtract both sides 2000
4z=28000
Divide both sides by 4
z=7000
Now, plug in z as 7000 into y=1000+z to get y =8000
Now, x =y+z plug in the y and z values
x= 8000+7000=15000
Let's check with interest,
15000(7%)+8000(8%)+7000(6%)=2110
1050+640+420= 2110
2110=2110.
Yes! The calculations are correct!
A car rental service charges a one-time fee of $19.99 in addition to $0.29 per mile drive. If the final total for renting the car is $73.93, select which equation best represents the situation. Let m represent the number of miles driven.
*Answer Choices*
19.99m + 0.29m = 73.93
19.99m + 0.29m = 73.93
(19.99 + 0.29)m = 73.93m
19.99 + 0.29m = 73.93
Answer:
Your answer is: D) 19.99+0.29m=73.93
We are trying to find the miles driven so therefore 0.29$ is per mile. So we have to see how many 0.29$ along with 19.99$ can fully add up to 73.93$

A gardener is planting a garden in the shape of a square. The gardener wants the side of the square garden to be between 15 and 18 feet long. The gardener wants to put a fence around the garden. How many yards of fencing will be required to enclose this square garden? Remember that 3 feet equals 1 yard. If every yard of fencing costs $1.50, how much will the gardener need to build the fence?
Answer:
$31.99Step-by-step explanation:
The idea begin this problem is to solve for the perimeter of the square garden using the expression for perimeter which is
Perimeter of square= 4L
given that the garden wants the side of the square garden to be between 15 and 18 ft long
Say we go with a length of 16ft (you can pick any number in the range just maintain the formula for the perimeter)
perimeter= 4(16)
perimeter= 64ft
now we have to convert ft to yard
1 yard=3ft
x yard=64ft
cross multiply we have
x=64/3
x=21.33 yards
given that a yard cost $1.5, therefore 21.33 yards will cost
=21.33*1.5
=$31.99
amy runs 2 miles south, the turns around and runs 3 miles north. what is her displacement? a. 5 miles , b. 2 miles, c. 1 mile, d. 3 miles . i need hep now .
Option C, 1 mile is the correct answer
The displacement is 1 mile.
Given that, Amy runs 2 miles south, then turns around and runs 3 miles north.
What is displacement?Displacement is the change in the position of any point or object. It has a direction and magnitude, so it is a vector quantity. It is shown with an arrow that points from the starting position to the final position.
Now, Amy runs 2 miles south from the fixed point he runs in the north direction for 3 miles.
So, the displacement=1 mile
Therefore, the displacement is 1 mile.

If you were to multiply 3X25, you would have a product of 75.
Explain 2 ways you could rewrite 25 and using the distributive property still obtain a product of 75.
Include one example using addition and the other example using subtraction. For example, if I were to rewrite the integer 72, I could choose (70 + 2) or (80 – 8).
An example with addition is 3x(20+5) as 20 plus 5 is still 25, and an example with subtraction is 3x(30-5), as 30 minus 5 is 25.
