yesterday jamal scored -20 points on a puzzle today he scored more points use absolute value to describe today's score as a loss
The absolute value of Jamal's score is 20, indicating a loss of 20 points.
Explanation:In math, the absolute value of a number is the positive value of that number, regardless of its sign. Since Jamal's score on the puzzle was -20 points, we can use absolute value to describe today's score as a loss by taking the absolute value of the score. The absolute value of -20 is 20, which means that today's score was a loss of 20 points.

Reese spent $4.95 on cookie supplies. He sold 24 cookies at $2 each. His profit is how much more he got from selling the cookies than he spent. What was his profit?
To solve this problem, we should first find out how much Reese made from selling cookies. To do this, we have to multiply the cost of one cookie ($2) by the number of cookies he sold (24). This is modeled below:
24 * $2 = $48
To find Reese's total profit, we must subtract how much he spent on the supplies ($4.95) from his earnings ($48). This is modeled below:
$48 - $4.95 = $43.05
Therefore, Reese's profit is $43.05.
Hope this helps!

A pitcher contains 1 3/4 quarts of milk. How many fluid ounces of milk does the pitcher contain ?
1 3/4 quarts is equivalent to 56 fluid ounces. This conversion is done by first converting the mixed fraction to an improper fraction, and then multiplying by 32, which is the number of ounces in one quart.
Explanation:The subject of your question is Mathematics, specifically a unit conversion problem. You want to convert 1 3/4 quarts of milk to fluid ounces. We know that there are 32 fluid ounces in one quart. So, to convert quarts to fluid ounces, we multiply the number of quarts by 32:
For 1 3/4 quarts:
1. First, convert the mixed fraction to an improper fraction: (1 * 4) + 3 = 7/4 quarts
2. Multiply by 32(our conversion factor from quarts to fluid ounces): (7/4) * 32 = 56
So, 1 3/4 quarts is equal to 56 fluid ounces.

What is the first step in simplifying the expression 11x-2-3(1-7x)^2+(x+1)
Answer with Step-by-step explanation:
We are given a expression:
[tex]11x-2-3(1-7x)^2+(x+1)[/tex]
We have to determine the first step in the solution of the above expression.
First step will be to solve the term [tex](1-7x)^2[/tex]
We will firstly square the term 1-7x
[tex]11x-2-3(1-7x)^2+(x+1)\\\\=11x-2-3(1+49x^2-14x)+(x+1)\\\\=11x-2-3-147x^2+42x+x+1\\\\=-147x^2+54x-4[/tex]

simplify the expression (5-5i)-(-6-3i)
How do I solve this? Either teach me how, or help me with a few other simmilar ones.
Answer: Simplifying the expression of the substraction of the two complex numbers we get 11-2i
Solution:
(5-5i)-(-6-3i)
Eliminating the parentheses: 5-5i+6+3i
Grouping similar terms: (5+6)+(-5+3)i
Adding the similar terms: 11+(-2)i = 11-2i
Answer:
The simplify form of given expression is 11-2i.
Step-by-step explanation:
The given expression is
[tex](5-5i)-(-6-3i)[/tex]
Using distributive property, we get
[tex]5-5i-(-6)-(-3i)[/tex]
[tex]5-5i+6+3i[/tex]
Combined real and imaginary parts.
[tex](5+6)+(-5i+3i)[/tex]
[tex]11+(-2i)[/tex]
[tex]11-2i[/tex]
Therefore the simplify form of given expression is 11-2i.

What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
LMN is a triangle shown in figure.
Now,
Here, LMN is a triangle shown in figure.
By definition of proportionality, we get;
⇒ x / 15 = (20 + x) / (15 + 18)
Solve for x as;
⇒ x / 15 = (20 + x) / 33
⇒ 33x = 15 (20 + x)
⇒ 33x = 300 + 15x
⇒ 33x - 15x = 300
⇒ 18x = 300
⇒ x = 300/18
⇒ x = 50/6
⇒ x = 16 2/3
Thus, The value of x will be 16 2/3.

Find the nth term in the following sequence:
10, 19, 34, 55
Answer:
The nth term of sequence is [tex]3n^{2}+7[/tex]
Step-by-step explanation:
We need to find out the general recurrence relation of sequence:
[tex]10, 19, 34, 55[/tex]
if we see pattern of sequence that every square of each number 'n' is multiple of 3 and addition of 7
check this pattern by [tex]3n^{2}+7[/tex]
For n=1
[tex]3n^{2}+7[/tex]
[tex]3(1)^{2}+7[/tex]
[tex]3+7[/tex]
[tex]10[/tex]
For n=2
