15. If 8x + 6x + 5x + 3x = 440, then
2x + 5.8=

2x + 5.8= 45.8

Step-by-step explanation:

8x + 6x + 5x + 3x = 440

combine like terms:

22x = 440

divide both sides of the equation by 22:

x = 20

2x + 5.8= 40 + 5.8 = 45.8

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
