Answer:
first we'll have to do it in order which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)
Step-by-step explanation:
(22÷2-2.5)+(4-6+6)
(11-2.5)+(4-6+6)
(8.5)+(4)
= 12.5
Answer:
5units
Step-by-step explanation:
Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.
Using the formula
D = √(x2-x1)²+(y2-y1)²
D = √(2-2)²+(8-3)²
D = √0+5²
D = √25
D = 5
Hence the length of the side of the rectangle is 5units
7x + 2 is the correct answer
Answer:
see explanation
Step-by-step explanation:
To determine if (3, 1 ) is a solution to the system
Substitute x = 3 into both equations and evaluate. If the result is y = 1 for both then the point is a solution.
y = 
× 3 - 3 = 4 - 3 = 1
y = - 2(3) + 7 = - 6 + 7 = 1
Since both equations equal 1 then
(3, 1 ) is a solution to the system
