2). -7 < x < -3
3). (-5,8)
Step-by-step explanation: View picture below.
Find each variable find x and y
x and y are equal b/c the triangle is isosceles triangle
when we see the angles of the triangle we get 2 equal angles
so to find the value of each variable we've subtract the parallel sides from the angles which means x=180°-45° y=180°-45°
x=75° y=75
b/c of it's isosceles triangle the two sides and angles are equal

Solve the following inequality. 7x-2<10
Answer:x = < 12/7
Step-by-step explanation:
Add 2 to both sides:
7x - 2 (+2) < 10 (+2)
7x < 12
Divide both sides by 7:
7x/7 < 12/7
X < 12/7
The solution to the inequality 7x - 2 < 10 is x < 12/7.
Given that an inequality 7x - 2 < 10 we need to solve the inequality,
we know that,
Inequality in mathematics refers to a mathematical statement that compares two quantities, expressing that one quantity is greater than, less than, or not equal to the other.
Inequality is denoted using various symbols, such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).
To solve the inequality 7x - 2 < 10, we'll isolate the variable x.
Let's start by adding 2 to both sides of the inequality:
7x - 2 + 2 < 10 + 2
Simplifying the expression:
7x < 12
Next, divide both sides of the inequality by 7 to solve for x:
(7x)/7 < 12/7
Simplifying further:
x < 12/7
Therefore, the solution to the inequality 7x - 2 < 10 is x < 12/7.

A shirt that normally costs $19.99 is on sale for 15% off. How much does the shirt cost after the discount? $22.99 $19.99 $16.99 $24.50
Answer:
C. $16.99
Step-by-step explanation:
The shirt cost after the discount will be $16.99. thus option C is correct.
How to calculate the third party discounts?Third party discount is the multiplication result of the maturity value of the original rate to the rate of interest and time period.
Thus, we get:
Third party discount = Maturity value × R × T (R in decimal form).
We have been given that a shirt that normally costs $19.99 is on sale for 15% off. we are asked to find the discount on the shirt.
Therefore,
19.99 x 15/100
19.99 x 0.15 = 2.99
Then subtract from the total amount;
19.99 - 2.99 = 16.99
Therefore, the shirt cost after the discount will be $16.99. thus option C is correct.

Two waiters at a cafe each served 10 large fruit smoothies. The amount in each large smoothie is shown below. Witch Waiter's smoothies showed less variability
Answer:
Waiter’s B Large Smoothies showed less variability.
Step-by-step explanation:
First, we have to find the mean for Waiter A’s and Waiter B’s Large Smoothies.
1) Mean
Waiter A
19.1 + 20.1 + 20.9 + 19.6 + 20.9 + 19.5 + 19.2 + 19.4 + 20.3 + 20.9 = 199.9
199.9 / 10 = 19.99
Waiter B
20.1 + 19.6 + 20.0 + 20.5 + 19.8 + 20.0 + 20.1 + 19.7 + 19.9 + 20.4 = 200.1
200.1 / 10 = 20.01
Now, we have to use the Mean Absolute Deviation (MAD) to find which waiter’s smoothies showed less variability.
Waiter A
I19.99 - 19.1I = 0.89
I19.99 - 20.1I = 0.11
I19.99 - 20.9I = 0.91
I19.99 - 19.6I = 0.39
I19.99 - 20.9I = 0.91
I19.99 - 19.5I = 0.49
I19.99 - 19.2I = 0.79
I19.99 - 19.4I = 0.59
I19.99 - 20.3I = 0.31
I19.99 - 20.9I = 0.91
0.89 + 0.11 + 0.91 + 0.39 + 0.91 + 0.49 + 0.79 + 0.59 + 0.31 + 0.91 = 6.3
6.3 / 10 = 0.63
Waiter B
I20.01 - 20.1I = 0.09
I20.01 - 19.6I = 0.41
I20.01 - 20.0I = 0.01
I20.01 - 20.5I = 0.49
I20.01 - 19.8I = 0.21
I20.01 - 20.0I = 0.01
I20.01 - 20.1I = 0.09
I20.01 - 19.7I = 0.4
I20.1 - 19.9I = 0.2
I20.1 - 20.4I = 0.3
0.09 + 0.41 + 0.01 + 0.49 + 0.21 + 0.01 + 0.09 + 0.4 + 0.2 + 0.3 = 2.2
2.2 / 10 = 0.22
Now, we just have to compare those numbers.
0.63 > 0.22
So, Waiter B’s smoothies show less variability.

40 tickets were sold for a concert, some at 75 cents and the rest at $1.25. if the total raised was $42, how many had the cheaper ticket. please i need this for an assignment
Answer:
34
Step-by-step explanation:
$1.25 = 125 cents.
$42 = 4200 cents
Tickets sold at 75 cents = x
Tickets sold at 125 cents = y
x + y = 40
75x + 125y = 4200
Multiply the first equation by 75
75x + 75y = 3000
75x + 125y = 4200
Subtract the the second equation from the first.
75x + 75y = 3000
- 75x + 125y = 4200
-------------------------------
0 - 150y = - 1200
Divide both sides by - 150
-150y/-150 = -1200/-150
y = 8
Substitute y = 8 into the first equation
x + y = 42
x + 8 = 42
x = 42 - 8
x = 34
34 tickets were sold for 75 cents
8 tickets were sold for $1.25

-Please write the full solution!
Answer:
