You can use Heron Formula in the calculator to output the result, but i still show you the steps on paper thro
lengths of the 3 lines: \sqrt{392} , \sqrt{676} , \sqrt{676}
s= (\sqrt{392} + \sqrt{676} + \sqrt{676})/2=35.89949494
area= \sqrt{s(s- \sqrt{392} )(s- \sqrt{676})^2 } =238
Answer:
2/5
Step-by-step explanation:
add all marbles together: 10 marbles
since only 4 are red, the fraction would be 4/10
4/10 can be simplified to 2/5
The second bicycle would weigh 1.32142857143 pounds or rounded to 1.32.
You would find this by multiply 18.5 by 1/14
Answer:
x=10
y=2
Step-by-step explanation:
1)add the equations and find what x is.
x-y=8
+x+y=12
—————
2x=20
— —
2 2
x=10
3)fill in x for the second equation.
x+y=12
since x=10,replace x with 10.
10+y=12.
subtract 19 from both sides.
10+y=12
-10 -10
—————-
y=2
