the answer to the question is f(2z)=(2z)²
Answer:
35 meters
Step-by-step explanation:
Since 1cm=10meters, we can do 3.5cm=how many meters?
To get from 1 to 10 we multiply by 10.
So we can do 3.5x10 to get 35 meters.
Hope this helps!
Answer:
YEEEEEEEEEEEEEEEEEEETTTTTTTTTTTTTTT
Step-by-step explanation:
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.

you have to take the amount she reads and divide it by the number of pages per 303030 minutes then take the answer times the amount of time it takes
200200200/252525=792.7935848
792.7935848x303030=240240240
