Arturiano [62]

I think this is right.. I tried my best. If u get it sorry... I’m very sorry

1. Divide 7.20 by 4 since the 4 are the pencils

2.divide 7.20 by 5 ( 5 represents the erasers )

3. Then finally multiply 1.44 from 7.20/5 and
2 and u get 2.88

Answer:

$f(a) = \frac{(a+5)}{(a-1)}$

Step-by-step explanation:

Given : $f(x) = \frac{(3+x)}{(x-3)}$

In order to find $f(a+2)$ we will substitute $(a+2)$ for $x$ in the given function, that is :

$f(a) = \frac{(3+a+2)}{(a+2-3)}$

$f(a) = \frac{(a+5)}{(a-1)}$

Rita can make 8 cakes for a bakery each day. So far, she has orders for more than 32 cakes. Right now, Rita needs more than four

Andru [333]

Answer:

x > 4

Step-by-step explanation:

Calling x the number of days Rita needs to bake the total amount of cakes, then inequality is x*8 > 32. Because she has orders for more than 32 cakes and can make 8 cakes per day. Dividing by 8 every side of the inequality gives: x > 4. Graph of the solution is attached (notice that 4 is not included).
