Answer would be letter (b)
The answer is -0.6 using long division.
Answer:
d represents distance
d = -16.8
Step-by-step explanation:
From the question, we are to find the vale of d from the expression
12+d = -4.8
Subtract 12 from both sides
12+d-12 = -4.8-12
d = -4.8-12
d = -16.8
Hence the value of d that makes two equation true is 16.8
d represents distance
Let 11x + 15y + 23 = 0 be equation (1)
And 7x - 2y - 20 = 0 be equation (2)
Multiply equation (1) by 2:
22x + 30y + 46 = 0
Multiply equation (2) by 15:
105x - 30y - 300 = 0
Add equations (1) and (2):
22x + 105x + 30y - 30y + 46 - 300 = 0
127x - 254 = 0
127x = 254
x = 254/127
[x = 2]
Substitute x = 2 in equation (1) to find y:
11(2) + 15y + 23 = 0
22 + 15y + 23 = 0
15y + 45 = 0
15y = -45
y = -45/15
y = -3
Therefore, x = 2 and y = -3.
