Answer:
LCM = 84 GCF = 1
Step-by-step explanation:
LCM of 7 and 12 is 84.
GCF(7,12) = 1
LCM(7,12) = ( 7 × 12) / 1
LCM(7,12) = 84 / 1
LCM(7,12) = 84
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
GCF of 7 and 12 is 1. Now calculate the prime factors of 7 and 12, then find the greatest common factor (greatest common divisor) of the numbers.
To find the GCF of two numbers: List the prime factors of each number. Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.
Answer:
HCF: 1
LCM: 84
Step-by-step explanation:
7 is a prime number. Nothing but 1 and 7 divide into which means that twelve and 7 have no highest common factor but 1.
The lowest common multiply (because 12 and 7 are prime to each other ) is 12 * 7 = 84

Answer:
40°
Step-by-step explanation:
The interior sum of a triangle is 180°. Since we have two known angles we will subtract those values from 180 to obtain our third angle and so:
180°-65°-75°=40°
kx-4=9
Move -4 to the other side. Sign changes from -4 to +4
kx-4+4=9+4
kx=13
Divide by k for kx and 13
Cross out k and k = 1.
x=13/k
Answer: x=13/k
Answer:
27.33333... mph
Step-by-step explanation:
Find 1/3 of 20 1/2: 1/3*41/2=41/6
That equals 6.83333...
Now add 20 1/2 and 6.83333 = 27.3333...
Therefore, 27.33333... mph
