3(2b-4a+3c) if a =1/2,b=3, and c=-2/3

valentina_108 [34]

This is just substitution. so 3(2(3)-4(1/2)+3(-2/3)= 3(6-2-2)= 3(2) = 6. Basically you plug in the values they gave you for the variables and then just solve one step at a time

Which of the followingis multiplicative of -a? (-1/a a 1 1/a)

Elodia [21]

Given:

The given value is $-a$ .

To find:

The multiplicative inverse of $-a$ .

Solution:

We know that $y$ is the multiplicative interval of $x$ if $xy=1$ .

Let $x$ be the multiplicative inverse of the given value $-a$ . Then,

$(-a)\times x=1$

Divide both sides by $-a$ .

$x=\dfrac{1}{-a}$

$x=-\dfrac{1}{a}$

Therefore, the multiplicative inverse of $-a$ is $-\dfrac{1}{a}$ . Hence the correct option is A.

A and b are positive integers. Find −2a+3b if a^3 b^2=72.

Alexxx [7]

The answer for "-2a + 3b" is 5.

To solve this equation, you must first find "a" and "b". A^3 times B^2 = 72. In this case, a = 2 (2*2*2 = 8) and b = 3 (3*3 = 9) since their outcomes multiplied together equal 72.

Now you fill in for "a" and "b". "-2*2 + 3*3" before adding you do all the multiplying, which leaves "-4 + 9". Combining like terms gives you 5.

I hope this helps!!
