Carl has three lengths of cable,

1 answer:

6 0

Lowest common denominator for 3,4,6 is 12

5/6 = 10/12
1/4 = 3/12
2/3 = 8/12

a)
10/12 + 3/12 = 13/12 = 1 1/12
So you need to use first and second cables

b)
3/12 + 8/12 = 11/12
To reach 1 yard Carl need 1/12 yard cable

Prove the sum of two rational numbers is rational where a, b, c, and d are integers and b and d cannot be zero.

Savatey [412]

Answer:

Step-by-step explanation:

Since a,b,c and d are integers,

bd, ad and cb are also integers because product of two integers is an integer

Also, ad + cb is an integer because sum of two integers is an integer.

(ad + cb)/bd is a rational number

a/b + c/d is a rational number

5. At a classroom costume party,

Alenkasestr [34]

The required simplified value of b + g is 21.

Given that,

At a classroom costume party, the average age of the b-boys is g, and the average age of the g girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42- year-old teacher) is b+g,

<h3>What is average?</h3>

The average of the values is the ratio of the total sum of values to the number of values.

Here,

The average age of the b-boys is g.
The average age of the g-girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42-year-old teacher) is b+g,

Now,
average of n = 3 (b , g , b+g)
Average = g + b + 42 / 3
b + g = (b + g + 42 ) / 3
3b + 3g = b + g + 42
3b - b + 3g - g = 42
2b + 2g = 42
2 (b + g) = 42
b + g = 21

Thus, the required simplified value of b + g is 21.

If log subscript 2 left parenthesis 3 x minus 2 right parenthesis equals 4, then what is the value of x?

elena-14-01-66 [18.8K]

Answer:

x = 6

See image.

Step-by-step explanation:

Logarithms are just another way to write exponents. The base on the logarithm that is the small font subscript IS the base (normal font/on the line) of an exponential equation. The "answer" in the logarithmic equation is the exponent (small font/superscript) .It is just a triple shuffle. When the logarithmic equation cant be worked on to solve it, CHANGE IT to exponential form. See image.
