Step-by-step explanation:
Let the numbers be x and y
2 consecutive even nos.
therefore y = x+2
twice of the first (2x) is 46 more than y
2x = y+46
Solving both the equations
x - y + 2 = 0
(-)2x - y - 46 = 0
____________
-x + 0 + 48 = 0
____________
x = 48
y = x+2
= 48 +2
= 50
Therefore the 2 nos. are 48 and 50

Answer:
Rules & Examples of Integers multiplication.
Step-by-step explanation:
A rational number is a number that can be expressed as a fraction of integers (positive or negative numbers). Every integer is a rational number.
They are multiplied based on following rules :
- Positive (+) x Positive (+) = Positive (+) , +2 x +2 = 4
- Positive (+) x Negative (-) = Negative (-) , +2 x -2 = -4
- Negative (-) x Positive (+) = Negative (-) , -2 x +2 = -4
- Negative (-) x Negative (-) = Positive (+) , -2 x -2 = 4
X + (x + 1) = 7
2x + 1 (-1) = 7 (-1)
2x = 6
2x/2 = 6/2
x = 3
x +1 = 3 + 1
x + 1 = 4
The two integers are 3, 4

The answer is c. they are indeed vertical angles
Lbs : 4, 8, 12, 16
cost : 6, 12, ?, 24
12 lbs would cost u $ 18 because the apples cost (6/4) = 1.50 per lb
