Answer:
X = 13/3
Step-by-step explanation:
24x - 6 = 9x + 38+21
24x - 9x= 38 + 21 + 6
15x = 65
X = 65/15 = 13/3
X = 13/3
Answer: y=-1x+5
Step-by-step explanation:
1. Use slope-intercept formula (y = mx + b) to find the slope which is represented by the variable 'b'.
m = ∆y / ∆x
m = -1 / 1
m = -1
y= -1x + b
2. Use any cooresponding x and y values to substitute into the formula. Ex: (x,y) → (1,4)
y = mx + b
4 = -1(1) + b
4 = -1 + b
5 = b
3. Plug in the values found into the formula.
y = -1x + 5
The answer is d. it isn’t an exact number
The surface area formula for any sphere is 4(pi)(radius)^2
The radius is half of the diameter.
18.6 / 2 = 9.3
So, plug into the formula and solve.
4(3.14)(9.3)^2 = 1086.3 mm^2
Answer:
<h2>12.5663706144 or just 12.57.</h2>
Step-by-step explanation:
4 x pi = 12.57
<h3>Estimate </h3>
Pi is approx. equal to 3.14
4 x 3 = 12
