Step-by-step explanation:
Since we need to find the radius, then we will rearrange the second formula.
So, the radius of a circle that has a circumference of 457 is about 72.8 cm
Answer:
1) x = 6, y = -2 + 1/3x
2)
Step-by-step explanation:
1) x-3y=6
-3y=6-x, 6-x/-3y
y = -2 + 1/3x
x - 3(-2+1/3x) = 6
x - 6 + x = 6
2x =12
x = 6
2) x=3y+4
-3y = -x+4
y = -x/-3 +4/-3
y = 1/3x + -4/3
x = 3(1/3x + -4/3)
I am unsure about x on number two...
Answer:
is h is 3, then your answer would be 21 + 28 = 49
since 7 x 3 = 21 and 7 x 4 = 28 you add 21 and 28 which would get you 49
I think so but if not goodluck to u :)
-85 is the answer (calculator)
