The diameter is 30 cm, therefore the radius is 15 cm. The circumference of the tire is found by using the formula C = 2πr. C ≈ 2(3.14)(15) ≈ 94.2 cm. 5 km = 500,000 cm (5 x 1000 x 100). 500,000 ÷ 94.2 ≈ 5307.86 or about 5300 times (revolutions). (using π, instead of 3.14, I got 5305.16 revolutions)
3y - yz = 2z
First separate y from 3y - yz = 2z
3y - yz is the same as y * (3 - z) so...
y (3 - z) = 2z
Now divide both sides by (3 - z)
y = 2z / (3 - z)
The answer is y = 2z / (3 - z), the answer you stated is correct except at the end, it isn't - 2, but - z, and also you should include parenthesis around it. Found this helpful? Give it a Brainiest reward if so.
The answer is going to be 14 15 16
14+15+16 = 45
