x^3 = 125/27
Take the cube root on both sides.
cuberoot{x^3} = cuberoot{125/27}
x = 5/3
Answer:
130
Step-by-step explanation:
Hello There!
An included angle is equal to half the measure of its included arc
So more specifically for this circle
∠mABC = arc(mAB)
So in order to find the value of x we are going to want an equation
Because angle ABC is equal to 1/2 of arc AB we are going to want to multiply angle ABC's expression by two
So 2(3x+32) = 10x+20
now we solve for x
step 1 distribute the 2
2 * 3x = 6x
2 * 32 = 64
now we have
6x + 64 = 10x + 20
step 2 subtract 20 from each side
64 - 20 = 44
20 - 20 cancels out
now we have 6x + 44 = 10x
step 3 subtract 6 x from each side
10x - 6x = 4x
6x - 6x cancels out
now we have 44 = 4x
step 4 divide each side by 4x
44/4=11
4x/4=x
we're left with x = 11
finally we want to plug in 11 to x for (10x+20)
10(11)+20
10*11=110
110+20=130
so arc ab = 130
Solve both equations for x:
2x+7 = 3
2x = -4
x = -2
Plug x into the equation which contains b:
b(-2) -10 = -2
-2b = 8
b = -4
Answer:
b = -4
x = -2

The statement 'of ' represents multiplication.
thus, baby = 1/40 * 120 = 3 tons.
1 ton is 2000 pounds.
Hence, 3 is 6000 pounds.
