X + 3/3 = y + 2/2
2x + 6 = 3y + 6
2x = 3y
x = 1/2(3)(y)
x/3 = y/2
The answer is C
The inequality of the given question is x+2y ≥ 150
Step-by-step explanation:
Given,
The mark out of 100 for Term 1 exam and twice the mark out of 100 for the term 3 exam are added together.
And, he needs to obtain 150 to achieve the grade.
To find, the inequality to student mark
Let,
The student got x in Term 1 and y in Term 2.
To be passed, he needs to get x+2y
So, the requited inequality will be x+2y ≥ 150
Answer:
To find why he would do this, we need to understand what all the possible first steps are in this equation.
You could add 4 to both sides.
You could subtract 4 from both sides.
You could subtract 5x from both sides.
You could subtract 6x from both sides.
Any of these work. In Bernard's case, he added 5 negative x tiles, meaning he subtracted. C and D already make no sense, but allow me to further explain. By him subtracting 5x from both sides, the equation turns into:
-4 = x + 4
By this point, he can just subtract 4 from both sides to find the value of x. But the question asks for why he did the first step. Therefore, it would
Answer:
x = 
Step-by-step explanation:
The altitude of the triangle must equal 4 because it is a right triangle with another leg of 3 and a hypotenuse of 5 (reason is due to the pythagorean theorem)
Therefore, the triangle on the right has legs of 4 and 7 and, again, use the phythagorean theorem to find 'x' (the hypotenuse)
