For which of the following values of "a" will x = 5 be a solution to the equation ax + 1 = 2x + 26 ? * a -4
b 5
c7
d-10

b. 5.

Step-by-step explanation:

If x = 5

a(5) + 1 = 2(5) + 26

5a + 1 = 10 + 26

5a = 36 - 1

5a = 35

hence a = 5.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
