Alright. One way you can do this is to list multiples of each denominator:
1/4:
4, 8, 12, 16, 20, 24, 28, 32, 36...... and so on
3/7:
7, 14, 21, 28, 35, 42, 49, 57, 63......
1/11;
11, 22, 33, 44, 55, 66, 77, 88......
Keep going until you see the least common denominator!
Now an easier way to do this is by multiplying all of the numbers in the denominator then get the factors:
4*7*11 = 308
And since those are not divisible by a whole number (besides 4 but 308 won't be divisible by 2*7*11)
Therefore 308 is the least common denominator.
Answer:
-7 degrees
Step-by-step explanation:
Dropping 12 degrees means that it will get colder by 12 degrees. The colder it gets, the lower the temperature. 5 degrees - the current temperature, is going to be dropped by 12 degrees. To calculate this: 5-12 = -7 (degrees)
Answer:
<D is correct its confusing on the solving but
Step-by-step explanation:
Answer:
the answer to x+(-9)=32 is x=41
Answer: 1) B is correct, constant of variation is -2.
Step-by-step explanation:
1)
Direct variation states that a relationship between the two variables. we say y varies directly as x
i.e, or y =kx.................[1] ; where k is the constant of variation.
Given the equation:
Divide both sides by -4 we get;
Simplify:
.......[2]
On comparing equation [2] with [1] we get;
k = -2
