You need to multiply the cost of each notebook by how many notebooks the store wants to buy.
-56 A negative Multiplied by a Positive is a Negative
Start by subtracting 2. You end up with -5x=20. Because the five is negative, the second number must be negative, because two negatives always make a positive in multiplication. Pick the only negative answer, which is D, -4
Answer:
m∠ABD = 126°
Step-by-step explanation:
if both angles make a linear pair then their sum equals to 180°
you can solve for x
m∠ABD + m∠CBD = 180
6x-12 + x+31= 180
7x + 19 = 180
7x = 161
x=23; now solve for
m∠ABD = 6x - 12 = 6(23) - 12 = 126°
The correct answers are :
x + y = -1
x + 4y = 0
8x - 3y = 20
