Answer:
4(t+25) = (t+50) - 4 (0.15t)
4t + 100 = t + 50 - 0.6t
4t + 100 = 50 + 0.4t
4t - 0.4t + 100 = 50 + 0.4t - 0.4t
3.6t + 100 = 50
3.6t + 100 - 100 = 50 - 100
3.6t = -50
3.6t / 3.6 = -50 / 3.6
t = - 13.9
Step-by-step explanation:
Circumference of a circle is : 2.π.R (R = Radius)
Circumference = 2.π.(7) = 14.π = 14 x 3.1416 = 43.98 in ≈ 44 in
If Nico gave away some red circles and you would like to know how many red circles does he have left, you can calculate this using the following step:
Nico has 15 red circles.
n ... the number of red circles that he gave away
15 - n ... the number of circles that Nico still has
The correct result would be 15 - n.
Plus x on bot sides. then divide both sides by 2 to get y by itself.
