For the given numbers, the lowest bound : 41.66. the upper bound: 42.19
<h3>How are upper and lower boundaries discovered?</h3>
To determine a rounded number's upper and lower bounds: Determine the place value of the claimed level of accuracy. By two, multiply this place value. Find the upper bound by adding this amount to the provided value, and the lower bound by deducting this amount from the given value.
The lower: a=49.35. b=7.69
so the lower bounds is:
a-b=49,35-7.69 =41.66 = a=49.49.34.
b=755 the upper = a= So the upper bounds is = a-b= 42.79.

This is two lines in slope intercept form and we want their intersection. We just set the ys equal.
-3x - 3 = (-1/2)x + 2
Multiply both sides by 2 to clear the fractions,
-6x - 6 = -x + 4
-10 = 5x
x = -10/5 = -2
y = -3x - 3 = -3 (-2) - 3 = 6 - 3 = 3
Check:
y = (-1/2)x + 2 = (-1/2)(-2) + 2 = 1 + 2 = 3, good
Answer: x=-2, y=3
Answer:
1/2
Step-by-step explanation:
Factor both the numerator and denominator down to prime factors:
500 = 22 * 53
1,000 = 23 * 53
Calculate the greatest common factor, GCF (also called greatest common divisor, GCD), by taking all the common prime factors of the numerator and denominator, by the lowest exponents:
gcd (22 * 53; 23 * 53) = 22 * 53
Divide both the numerator and denominator by their greatest common factor, GCF (also called the greatest common divisor, GCD):
500/1,000 =
(22 * 53)/(23 * 53) =
((22 * 53) ÷ (22 * 53)) / ((23 * 53) ÷ (22 * 53)) =
1/2
Rewrite result:
1 ÷ 2 = 0.5 as a decimal number.
