Orders are a, b, c, lets write equations to represent the problem's info:
a + b = 150
b + c = 100
a + c = 150
so we have 3 unknowns and 3 equations, so we can solve.
<span>Use the first equation:
a + b = 150
</span>a = 150 - b
and substitute in the 3rd:
<span>a + c = 150
</span>150 - b + c = 150
then
b = c
and we can substitute that in the original equation:
<span>b + c = 100
</span>2b = 100
b = 50
c = 50
and substitute in the first equation:
<span>a + b = 150
</span>a = 150 - b = 150 - 50
a = 100
then a = 100, b = c = 50
Answer:
30sequences
Step-by-step explanation:
Using nx (n-1)
And
n is the number of ternary digits in the number.
So For 6 digits n is 6 so the number of numbers that have exactly one 1 AND exactly one 2 is 30.
That is 6(6-1)= 30
Answer:
1.5
Step-by-step explanation:
8 - 2 = 6
6 / 4 = 1.5
Answer:
One Decimal Place Rule #1: If the last digit in 44.24 is less than 5, then remove the last digit. One Decimal Place Rule #2: If the last digit in 44.24 is 5 or more and the second to the last digit in 44.24 is less than 9, then remove the last digit and add 1 to the second to the last digit.
