Answer:

Step-by-step explanation:

We can use a number of ratio units to represent b that is the LCM of 8 and 6. That value is 24. Then multiplying the first ratio by 3 and the second by 4, we have ...

a:b = 9:24 and b:c = 24:44

Then the ratios of all are ...

a : b : c = 9 : 24 : 44

and the sum is 9+24+44 = 77.

Maury and Tyra are making phone calls to state representatives' offices to lobby for an issue. Muary can call all 120 state repr

oee [108]

Maury = 120/10 (12 calls/hour)
Tyra = 120/8 (15 calls/hour)

Together they are 27 calls per hour.
120 / 27 = 4.4444444444

So it'd take them 4.44444444 (recurring) hours to make 120 calls.

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?

AVprozaik [17]

Answer:

The correct answer is Option 4: 12

Step-by-step explanation:

Given equation is:

$6-\frac{3}{4}x+\frac{1}{3} = \frac{1}{2}x+5$

We have to find a number that is common multiple of all the denominators or least common divisor

So to find the LCM

The numbers in denominator are: 4,3,2

So,

$4=> 4,8,12,16\\3 => 3,6,9,12,15\\2=> 2,4,6,8,10,12$

It can clearly be seen that 12 is the LCM of all three numbers so the equation will be multiplied with 12 to eliminate the fractions.

$12*6-12*\frac{3}{4}x+12*\frac{1}{3} =12* \frac{1}{2}x+12*5\\72-9x+4 = 6x+60$

Hence,

The correct answer is Option 4: 12
