Answer:

$\sqrt{2}$ and 4 $\sqrt{11}$

Step-by-step explanation:

To simplify like surds, add/ subtract the coefficients.

(a)

$\sqrt{2}$ (6 - 5)

= $\sqrt{2}$ (1)

= $\sqrt{2}$

(b)

$\sqrt{11}$ ( 1 + 3)

= $\sqrt{11}$ (4)

= 4 $\sqrt{11}$

Answer:

x = 2.4

y = 31

Step-by-step explanation:

Just want to double check our answer.

0 divided by 2 is 0.

You can use the multiplicative identity property: the product of any number and zero is still zero.

Hope this helped :)

Chia is planning a sailing party for her friends the boat rental is $150 plus an additional $15 per person see it has saved up $

storchak [24]

150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67
So Chia can invite 16 people

When salt and water are combined, they form a salt or saline solution. How much ml of water must be added to 150 mL of an 80% sa

Vinvika [58]

Answer:

We must add 400 ml of water.

Step-by-step explanation:

We can use the following equation:

$C_{i}V_{i}=C_{f}V_{f}$

Where:

C(i) is the initial concentration of the solution (80%)
C(f) is the final concentration of the solution (30%)
V(i) is the initial volume (150 ml)
V(f) is the final volume

Now, we just need to solve the equation for V(f).

$V_{f}=\frac{C_{i}V_{i}}{C_{f}}$

$V_{f}=\frac{80*150}{30}$

$V_{f}=400\: ml$

Therefore, we must add 400 ml of water.

I hope it helps you!
