False.
Replace x with 0 and solve:
2(0) + 3 = 0+ 3 = 3
3 is not greater than 13 so the answer is false.
Answer:
This is a trial and error problem
we can divide 30 eyes by 2 eyes on each animals to know that there is 15 animals
15 animals now make a random guess
Find out the difference of feet. 1 dog has 4 feet - 2 chicken feet = 2 feet increase or decrease so if we need to increase by 2 we add 1 dog and if we need to subtract to then we add 1 chicken
11 dogs and 4 chickens
that is 44 feet + 8 feet = 52 feet
52 - 44 feet needed = 8 feet
8 / 2 feet decrease = 4 more chickens needed
11 - 4 (subtracting 4 dogs off)= 7
4 + 4 (replacing the dogs with chickens)= 8
7 dogs and 8 chickens
7 x 4 = 28
8 x 2 = 16
28 + 16 = 44
7 dogs and 8 chickens
Hope this helps
Step-by-step explanation:
Answer:
81b + 4 - 14/3b
Step-by-step explanation:
divide by 3b, u can leave the fraction in there
Answer:
The factored equation would be 4x(3y + 7z)
Step-by-step explanation:
In order to find this, look for the greatest common factor and pull it out. Since both have factors of 4 and both have an x, we pull those out. We then divide each term by 4x to get what is left over.
We have a circle of radius 5 m inside a square of side 10 m. The shaded area is:

Now, we calculate the area of the square and the circle:

Finally, the shaded area is:
