Answer:

a < 42

Step-by-step explanation:

Question : 4a + 9a - 6a < 42

Answer :

4a + 9a - 6a < 42

Combine like terms.

13a - 6a < 42

7a < 42

Divide both sides by 7.

a < 42

Hope this helps you :-)

Answer:

$\large\boxed{\boxed{\underline{\underline{\maltese{\pink{\pmb{\sf{\: Solution :- \: a \: < \: 6 }}}}}}}}$

Step-by-step explanation:

We need to solve the below given inequality $\downarrow$

4a + 9a - 6a < 42

For this, we need to combine all the like terms at first. So

4a + 9a - 6a < 42

13a - 6a < 42

7a < 42

We know that, 42 is divisible by 7. So, let's divide both the sides of the inequality by 7.

7a < 42

a < 42/7

<u>a < 6</u>

Hope it helps!

given y left parenthesis z right parenthesis equals space fraction numerator z squared minus 1 over denominator z left parenthes

aivan3 [116]

The simplification of the given algebraic expression is;

yz = (z + 1)/z(z - 1)

<h3>How to simplify algebraic expressions?</h3>

We are given y left parenthesis z right parenthesis which is expressed as; yz

Now, we are given the algebraic expression that yz equals space fraction numerator z squared minus 1 over denominator z left parenthesis z minus 1 right parenthesis squared end fraction

z squared minus 1 over denominator z left parenthesis z minus 1 right parenthesis squared end fraction is expressed as; (z² - 1)/z(z - 1)²

Thus, our main expression is;

yz = (z² - 1)/z(z - 1)²

Factorizing the numerator and denominator gives;

yz = (z + 1)(z - 1)/z(z - 1)(z - 1)

(z - 1) is common to both numerator and denominator and as such, we now have;

yz = (z + 1)/z(z - 1)

You should multiply by 4 before adding 16 to solve the inequality 11 > a/4 - 16.

3241004551 [841]

11 > $\frac{a}{4}$ - 16

False, you should add 16 first to make the equation easier. If you multiplied by 4, you would have to multiply everything by 4, whereas by adding 16 first you only have to solve 27 · 4 to get a.
