Radius = d/2 = 1.7 in
circumference = πd ≈ 3.14*3.4 in = 10.68 in
Answer:
A.
= ![\frac{3}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B12%7D)
Step-by-step explanation:
of the students wore shorts.
of the students wore jeans.
Converting the fractions of the students who wore shorts and jeans respectively;
= 0.25
= 0.25
This means that the ratio of students who wore shorts is the same as that of students who wore jeans.
i.e
= ![\frac{3}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B12%7D)
Answer:
(22, - 24)
Step-by-step explanation:
Multiply the first equation by -5 to make the y's so you can add the up to zero.
-5(2x + y = 20)
-10x - 5y = -100 Add the second equation thn solve for x
<u> 6x + 5y = 12 </u>
-4x = -88
x = 22
Plug 22 in for x in either equation
2x + y = 20
2 (22) + y = 20
44 + y = 20
y = -24
