Answer:
Multiplication property of equality
Step-by-step explanation:
The multiplication property of equality states that if x = 1, then you can multiply both sides by the same number and both sides will stay equal to each other. Therefore, if x = y, then you can multiply both sides by the 3 to make 3x = 3y and they will still be equal to each other.
I hope you find this helpful. :)
You divide each side of the equation by 'a', and you immediately have
the value of 'x' in terms of 'a and 'b'.
Answer:
the area is 5.25 and the perimeter is 14
Step-by-step explanation:
first multiply 6cm and 1 3/4 which converts to 1.75, so 6x1.75+10.5 and to find the area of a triangle you multiply the base by the height and divide by 2 so 10.5 divided by 2 is 5.25 for the area, the perimeter is 14 because you're supposed to add all the sides and the sum is the perimeter 20 6 and 1/4 is converted to 6.25 therefore you add 6.25,6, 1.75 together to get 14
Answer:
I think that A, B, and C are correct.
Step-by-step explanation:
1. Since measures 2 and 3 are a linear pair, they equal 180 degrees. A is correct.
2. Since measures 3 and 4 are also a linear pair, they too equal 180 degrees. B is correct.
3. Measures 2 and 3 are already established to be 180 degrees (check answer 1) , and measures 3 and 4 are also 180 degrees (check answer 2). Since they are both 180 degrees, they are congruent (equal), so C is correct.
D is NOT correct. Measures 1 and 3 are equal because they are vertical angles. We also know that they are acute angles (less than 90) so adding them together will equal less than 180 degrees.
Measures 2 and 4 are equal because they are vertical angles, and they are obtuse (more than 90 degrees). Adding them together will equal more than 180 degrees.
Logic tells us that something less than 180 CANNOT be equal to something more than 180. This proves that 2 and 4 and 1 and 3 are not congruent.
D is WRONG
Answer:
5
Step-by-step explanation:
Remember:
Two negatives make a positive
A negative flips a sign
2 - (-4) + 3 + (-6) - (-2)
=
2+4+3-6+2
9-6+2
=5
