Answer:
n = -9
Step-by-step explanation:
4(0.5n − 3) = n − <u>0.25(12 − 8n)</u>
2n - 12 = n - <u>3 + 2n</u>
2n - 12 = 3n - 3
2n - 3n = - 3 +12
-1n = 9
n = -9
When it comes to measurement, the most accurate estimate would be the whole number. A ruler has calibrated marks. It would be easy to locate 25. But when it is located between 25 to 26, you would have to estimate the decimal points. Generally, calibration marks are up to the tenths digit. For further digits, that would only an estimation. So, the estimated digit in this problem is 3 in the hundredths place.
Step-by-step explanation:
(1/12) / (3/4)
= (1/12) * (4/3)
= 1/9.
Answer:
16 and -4
Step-by-step explanation:
Let the 2 numbers be x and y with x > y
x+y=12
x-y=20
Adding the 2 equations, term by term on both sides, will eliminate y leaving an equation in x that we can solve
(x+x)+(-y+y)=(12+20)
2x=32
x=16
16+y=12
y=-4
16+-4=12
12=12
16--4=20
20=20
Answer:
Step-by-step explanation:
2x-5y=8. y = 2/5x-8/5
Line q: (-6,2). Slope -5/2
y-2 = -5/2(x- - 6). y-2 = -5/2(x+6)
y-2 = - 5/2x - 6
y = -5/2x -6 +2
y = - 5/2x - 4
