ANSWER
![\begin{gathered} D.4x=20 \\ x=5 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20D.4x%3D20%20%5C%5C%20x%3D5%20%5Cend%7Bgathered%7D)
EXPLANATION
Let the number of people riding in each bus be x.
We have that 20 people are riding in 4 vans and there are x people in each van <em>(given that there is an equal number of people in each van)</em>.
This means that the product of the number of people in each van and the number of vans must be equal to the total number of people.
That is:
![\begin{gathered} 4\cdot x=20 \\ 4x=20 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%204%5Ccdot%20x%3D20%20%5C%5C%204x%3D20%20%5Cend%7Bgathered%7D)
Solve for x:
![\begin{gathered} x=\frac{20}{4} \\ x=5 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%3D%5Cfrac%7B20%7D%7B4%7D%20%5C%5C%20x%3D5%20%5Cend%7Bgathered%7D)
That is the answer.
Answer:
50a^6b^5
Step-by-step explanation:
I don't see answer choices, but this is the simplified version. To do this, multiply 10*5, a^3 * a^3 (which adds the exponents), and then b^3*b^2.
1/4*1/4=1/64 there are four parts per circle. Hope this helps!

Answer:
5) 140.8m^2 6) 360in^2
Step-by-step explanation:
5.
6.4 x 6.4 = 40.96
(7.8 x 6.4) ÷ 2 = 24.96
24.96 x 4 = 99.84
99.84 + 40.96 = 140.8m^2
6.
12 x 10 = 120in
13 x 10 = 130in
5 x 10 = 50in
(12 x 5) ÷ 2 = 30in
30 x 2 = 60in
60 + 50 + 130 + 120 = 360in^2
