Answer: -2

Step-by-step explanation: To subtract the integers -5 - (-3), it's important to understand that when we have minus a negative, we can change it to plus a positive.

So -5 - (-3) becomes -5 + (+3).

So starting at 0 on our number line, -5 moves us 5 units to the left. Then from there, positive 3 moves us 3 units back to the right and we end up at -2.

Therefore, -5 - (-3) is -2.

Mercury orbits around the sun is 87 24/25 earth days. Venus orbits the sun in 224 7/10 earth days, and Mars orbits the sun in 68

pav-90 [236]

For this case we have the following mixed numbers:

$87 \frac {24} {25}\\224 \frac {7} {10}\\686 \frac {49} {50}$

We convert each mixed number into decimal:

Mercury orbits: $87 \frac {24} {25} = \frac {25 * 87 + 24} {25} = \frac {2175 + 24} {25} = \frac {2199} {25} = 87.96$

Venus orbits: $224 \frac {7} {10} = \frac {10 * 224 + 7} {10} = \frac {2240 + 7} {10} = \frac {2247} {10} = 224.7$

Mars orbits: $686 \frac {49} {50} = \frac {50 * 686 + 49} {50} = \frac {34300 + 49} {50} = \frac {34349} {50} = 686.98$

Answer:

Mercury orbits: 87.96

Venus orbits: 224.7

Mars orbits: 686.98

A 450-pound circus tiger eats 15 pounds of meat per day. How many pounds of meat would you expect a 360-pound tiger to eat per d

navik [9.2K]

Hi :)

This kind of question is purely based upon proportionality. We are going to be using the cross product method to assess it.
First-hand, it can always help to write down the information that you do have, and the one that is missing.
Here;

450-pound tiger — > 15 pounds of meat
360-pound tiger — > ?? pounds of meat

The calculation you’ll want to use is the following:
360 x 15 / 450
The answer is 12 pounds.

Therefore, you would expect a 360-pound tiger to eat 12 pounds of meat per day.
I hope this helps! Have a nice day :)

Answer:

y varies of directly as x. This means that the equation is of the form y=kx where k is any number.

Substituting y=12 when x=4, we get

12=k×4⇒k=3

Hence, the required equation is y=3x.

The value of y when x=5 is y=3x5=15.
