After driving 152 km, 4/5 of a trip is completed. How long is the total trip? How many more kilometers must be driven to compl

nikitadnepr [17]

Answer:

1. Total Trip Distance = 190 kilometers

2. To complete the trip, 38 more kilometers left

Step-by-step explanation:

Let total trip be x kilometers.

So we can say

"152 is $\frac{4}{5}$ of total" --- this into equation is:

$152=\frac{4}{5}x\\x=\frac{152}{\frac{4}{5}}\\x=190$

Total trip is 190 km.

Since already driven 152, to complete 190, you have to drive $190-152=38$ kilometers more.

So, 38 more kilometers to complete the trip.

PLEASE AND THANK YOU CONFUSED ON THIS

ICE Princess25 [194]

After staring at this for a few seconds, I think the equation

$-5\sqrt{10}\cdot\sqrt{15}=[1]\sqrt{[2]}$

is asking you to simplify the left hand side so that it has a form matching the right hand side, and [1] and [2] are placeholders. My guess is that they're supposed to be integers.

Notice that

$\sqrt{10}=\sqrt{5\cdot2}=\sqrt5\cdot\sqrt2$

$\sqrt{15}=\sqrt{5\cdot3}=\sqrt5\cdot\sqrt3$

$\implies\sqrt{10}\cdot\sqrt{15}=(\sqrt5)^2\cdot\sqrt2\cdot\sqrt3=5\sqrt{2\cdot3}=5\sqrt6$

Then multiplying by -5, we have

$-5\sqrt{10}\cdot\sqrt{15}=-25\sqrt6$

so I believe [1] = -25, and [2] = 6.
