2x+2y =50
2(7)+ 2(3)=50
14+6 =50
20=/=50
This is false because when you substitute the variables with their numbers and then multiply and add, your answer does not equal 50
A mixed number is an integer and a fraction that is less than one (remember that x/x = 1.)
To simplify 25/10, calculate how many times 10 goes into 25 by dividing 25 by 10. The answer is 2 with a remainder of 5 (10 x 2 = 20, 25-20 = 5).
The mixed number is 2 and 5/10, which simplifies to 2 1/2.
The factored form of the equation is (x + 4)(x – 6) = 0.
When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there. So in other words no matter what way it is flipped or anything else that does not change the numbers on the sides it is congruent.
