Answer:

x=23

Step-by-step explanation:

When realizing that the total degrees of a line = 180 you can set the equation to that number.

So that it would look like this-

3x+18+93=180

then you would combine like terms (18+93=111)

3x+111=180

Subtract 111 to start to get x by its self

180-111=69

then it would look like this

3x=69

Divide by 3 and then you get the correct answer of 23!

Answer:

x=23°

Step-by-step explanation:

93°+(3x+18)°=180°

93°+3x+18°=180°

111°+3x=180°

3x=180°-111°

3x=69°

x=69°:3

x=23°

Find the greatest common factor

Lerok [7]

Answer:

(3b + 4) is the greatest common factor

Step-by-step explanation:

$3b(2b- 3)+4(2b-3) = 0 \\ {6b}^{2} - 9b + 8b - 12 = 0 \\ {6b}^{2} - b - 12 = 0 \\ {6b}^{2} - 9b + 8b - 12 = 0 \\ 3b(2b - 3) + 4(2b - 3) = 0 \\ (2b - 3)(3b + 4) = 0$

A cylindrical tank holds 352 cu. ft. of water. The height of the tank is 7 ft. Find the

Rzqust [24]

Answer:

0.3334 ft

Step-by-step explanation:

Measure the height and radius of the tank. The radius is the distance from the center of the tank to its outer edge. Another way to find the radius is to divide the diameter, or width, by two. Square the radius by multiplying the radius times itself and then multiply it by 3.1416, which is the constant pi.

Given height and volume: r = √(V / (π * h)),
Given height and lateral area: r = A_l / (2 * π * h),
Given height and total area: r = (√(h² + 2 * A / π) - h) / 2,
Given height and diagonal: r = √(h² + d²) / 2,
Given height and surface-area-to-volume ratio: r = 2 * h / (h * SA:V - 2),
Given volume and lateral area: r = 2 * V / A_l,
Given base area: r = √(A_b / (2 * π)),
Given lateral area and total area: r = √((A - A_l) / (2 * π)).
