N+3=5
n+3-3=5-3 (subtract 3 on both sides)
n=2
to check you substitute n with 2 and you get 2+3=5 (5=5)

So what they are telling you is that 5 is three higher than the variable n.
So n = 5-3
so n is 2.

Simplify the following completely, show all work. 4 + ✓-27

V125BC [204]

Answer:

4+3i $\sqrt{3}$

Step-by-step explanation:

the $\sqrt{-27}$ needs to be simplified

first, I broke it down to $\sqrt{-1}$ and $\sqrt{27}$

$\sqrt{-1}$ simplifies to i ;and can be broken down to $\sqrt{9}$ and $\sqrt{3}$

$\sqrt{9}$ can be simplified further to 3

Now all you have to do is put it together

4(which you didnt have to do anything to)+ 3i( 3 from the sqrt of 9 and i from the sqrt of -1) sqrt 3( which cant be simplified further)

2 Carrots €1.80 per kg How much does 250 g of carrots cost?

igomit [66]

Answer:

The cost of 250 g carrots is €0.45.

Step-by-step explanation:

Given that,

Cost of carrots is €1.80 per kg

We need to find the cost of 250 g of carrots.

1 kg cost = €1.80

We know that, 250 gram = 0.25 kg

0.25 kg cost = €1.80 × 0.25

= €0.45

So, the cost of 250 g carrots is €0.45.
