2nd graph (straight line)
Answer:69.1
Step-by-step explanation:
Circumference=2×π×radius
Circumference=2×22/7×11
Circumference=(2×22×11)/(1×7×1)
Circumference=484/7
Circumference=69.1cm
5 = 40/8
add 1/8 +40/8 =41/8
the answer is 41/8
Answer: w = 7, x = 6
Step-by-step explanation: Solve by substitution
W + b = 13
rewrite as b = 13 - w and substitute that value for b in the second equation
6.5w + 2b = 57.5 Then solve for w
6.5w + 2(13-w) = 57.5 . Distribute
6.5w + 26 - 2w = 57.5 . Subtract 26 from both sides. Combine like terms and simplify
6.5w - 2w = 57.5 - 26
4.5w = 31.5 Divide both sides by 4.65
w = 7 . Substitute 7 for w in the first equation and solve for b
7 + b = 13 . Subtract 7 from both sides
b = 6
3000cm because if you look at the variables there is no more letter m's than anything so if you cancel out and see what is equal to 30 then you get 3000cm!!!!!
