its not 6 i put that and got it wrong
I 2x +1 I < -4
the absolute value of a number is always positive. Therefore you cannot have an absolute value equal to a negative number.
the answer would be "no solution"
(8 ∙ 4) - One-half (10 + 12 + 16)
(8 ∙ 4) - (10 + 12 + 16)
(8 ∙ 4) - One-half (5 + 6 + 8)
(8 ∙ 4) - (5 - 6 - 8)
Based on the coordinate plane, a mathematical expression which can be used to find the area of triangle RST is: A. [(8 × 4) - 1/2 × (10 + 12 + 16)].
A triangle can be defined as a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.
Mathematically, the area of the triangle is given by the formula:
In this scenario, the mathematical expressions that would be used to find the area of triangle RST with points (-5, 6), (3, 4) and (-2, 2) are given by:
Area of rectangle = LW = 8 × 4
Area of triangle 1 = 1/2 × (2 × 5) = 1/2 × 10
Area of triangle 2 = 1/2 × (3 × 4) = 1/2 × 12
Area of triangle 3 = 1/2 × (2 × 8) = 1/2 × 16
The area of triangle RST = [(Area of rectangle) - 1/2 × (Area of triangle 1 + Area of triangle 2 + Area of triangle 3)].
Substituting the parameters into the formula, we have;
The area of triangle RST = [(8 × 4) - 1/2 × (10 + 12 + 16)]

Answer:
(8 ∙ 4) - One-half (10 + 12 + 16)
Step-by-step explanation:
The number of students who attended the museum opening is 80.
A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, A group of 100 people, some students and some faculty, attended a museum opening.
Assuming no. of students to be x and no. of faculty to be y.
∴ x + y = 100...(i)
Each student paid $10 per person for entrance to the museum and each of the faculty paid $25 per person for entrance and the total cost is $1300.
∴ 10x + 25y = 1300...(ii)
Now multiplying eqn(i) by 10 we get 10x + 10y = 1000...(iii)
Subtracting eqn(iii) from eqn(ii) we get 15y = 300 ⇒ y = 20 and substitting value of y in eqn(iii) we get x = 80.

STUDENTS X 10
FACULTY 100-X 25
10X + 25(100-X) = 1300
10X + 2500 -25X = 1300
10X - 25X = -2500 + 1300
-15X = -1200
15X = 1200
X = 1200/15
X = 80 STUDENTS <--------SOLUTION

The value of the expression 28 -18 - 10 is 0.
Subtraction is a mathematical operation. Which is used to remove terms or objects in the expression.
Given that the expression is 28 - 18 - 10.
The problem is asking you to subtract 18 from 28, and then subtract another 10 from the result.
First, you can perform the operation 28 - 18, which gives you 10.
Then, you can subtract 10 from 10, which gives you 0.
So the final answer is 0, which is option B.
