Answer:
x = 8
Step-by-step explanation:
29=7x + 5 -4x
add like terms: 29 = 3x +5
get your x variable on one side
24 = 3x
divide by 3
x = 8
check!
29 = 7(8) + 5 -4(8)
29 = 56 + 5 -32
29 = 51 - 32
29 = 29
Answer:
Step-by-step explanation:
1/3x > -4
cross multiply
1>-4 × 3x
1>-12x
solve for x
x = -1/12
<span>Length of outer track = sum of length of 10 pieces = circumference of the outer circle
if R is the Radius of outer circle then...
Circumference of the outer track = 2pi*R
Similarly the circumference of the inner track (with radius r) = 2pi*r
length of each outer piece is 3.4 inch more than length of inner piece
So total outer length is 10*3.4 =34 inches more than the inner length.
=> Outer Circumference - Inner Circumference = 34 inches
=> 2pi*R - 2pi*r = 34
=> 2pi(R -r) = 34
=> R-r = 34/2pi = 5.41 inches
=> R-r = Width of the track = 5.41 inches</span>
