Answer:
-3/2
Step-by-step explanation:
Rise/run
You count down/up however many until the line hits another point, and then go across until it matches. So I counted down 3 squares and over 2, and since it is going down it is negative.
I hope this helps :)
Answer:
A cube with sides of 5 cm holds 5 layers of 25 cm cubes.
A cube with sides of 10 cm could hold 10 layers of 100 cm cubes.
Step-by-step explanation:
For Cube a
Edge length = 10cm
Hence,
Volume = (side length)³
Volume = (10cm)³
= 1000cm³
For cube b
Side/Edge length = 5cm
Volume of cube = (5 cm)³
= 125 cm³
Gerardo statement is wrong.
Therefore, the correct explanation is given as:
A cube with sides of 5 cm holds 5 layers of 25 cm cubes.
A cube with sides of 10 cm could hold 10 layers of 100 cm cubes.
For this question, you would want to set up a system of equations.
Let x = Dog Food
Let y = Cat Food
5x+2y=20
x+4y=13
The next step is to eliminate a variable or do substitution. I personally find elimination easier. To eliminate the y, multiply the top equation by -2.
-10x-4y=-40
x+4y=13
The y's will cancel and you are left with:
-9x=-27
Divide by -9 on both sides and you get x=3. Now you want to take 3 and substitute it back into one of the original equations.
3+4y=13
Solve for y
4y=10
y=2.5
Plug both values into the top equation to check the values.
5(3)+2(2.5)=20
15+5=20
20=20
The answers are correct. Dog food is 3 dollars or euros and cat food is 2.50 euros.

<span>15000 feet
Looking up the height of Mt. Whitney, you can see it's 14,505 feet tall. Rounding that number to the nearest multiple of 1000 requires you to look at the hundreds digit which is 5. And the rule for rounding is "5 or greater, round up, 4 or smaller, round down". Since it's 5, we round up, giving 15000 feet</span>
5c+4 is equivalent
Its just simplified.
