Answer:
f=7
Step-by-step explanation:
42=6f
/6 /6
42/6=7
You divide 6 from 42, which leaves you with 7=f.
Answer:
the solution to the equations is :-
(4,3)
Step-by-step explanation:
here's the solution :-
=》x + 2y = 10
=》x = 10 - 2y
now, plugging the value of x in other equation :-
=》9x - 2y = 30
=》9 × (10 - 2y) - 2y = 30
=》90 - 18y -2y = 30
=》-20y = 30 - 90
=》y = -60 ÷ -20
=》y = 3
now, plugging the value of y in first equation,
=》x = 10 - 2y
=》x = 10 - (2×3)
=》x = 10 - 6
=》x = 4
so, the solution of the system is (4,3)
Your doing the square root
336 is the LCM for above group of non-negative integers and is divisible by each integers of this group.
Problem & Workout :
step 1 Address input parameters & values.
16 21 24
lcm (16, 21, 24) = ?
step 2 Arrange the group of numbers in the horizontal form with space or comma separated format
16, 21 and 24
step 3 Choose the divisor which divides each or most of the integers of in the group (16, 21 and 24), divide each integers separately and write down the quotient in the next line right under the respective integers. Bring down the integer to the next line if the integer is not divisible by the divisor. Repeat the same process until all the integers are brought to 1.
LCM of 16, 21 and 24
16 21 24
2 21 3
2 7 1
1 7 1
1 1
step 4 Multiply the divisors to find the lcm of 16, 21 and 24
8 x 3 x 2 x 7 = 336
lcm (16, 21, 24) = 336
336 is least common multiple for three numbers 16, 21 and 2
