Answer:
124 miles.
Step-by-step explanation:
From the question given above, the following data were obtained:
1 in = 20 miles
6 1/5 in =?
Next, we shall express 6 1/5 in decimal for easy calculation . This can be obtained as follow:
6 1/5 = 31 / 5
6 1/5 = 6.2 in
Finally, we shall convert 6.2 in to miles. This can be obtained as follow:
1 in = 20 miles
Therefore,
6.2 in = 6.2 in × 20 miles / 1 in
6.2 in = 124 miles
Thus, 6 1/5 in is equivalent to 124 miles.
Therefore, there are 124 miles between the two towns.
Answer:
26
Step-by-step explanation:
2. Given two consecutive positive EVEN integers, the square of the largest minus 10 times the smaller is 76. What is the sum of the two integers?
I'll call the two integers a and b. a=b+2
a² - 10b = 76
(b+2)² - 10b =76
(b+2)(b+2) -10b = 76
b² +2b + 2b +4 -10b = 76
b² +4b + 4 -10b = 76
b² -6b + 4 =76 subtract 76 from both sides to get the right side equal to zero
b² -6b +4 -76 = 0
b² -6b - 72 = 0 what factors of -72 add up to -6? The two that work are -12, 6
(b-12)(b+6) = 0 so b-12 = 0 or b+6 = 0
<u>+12 +12</u> -<u>6 -6</u>
b = 12 or b = -6 but b must be positive so b=12, a=14
a+b= 14+12 = 26
