Answer:
47 years old.
Step-by-step explanation:
Let c represent each children, 'f' represent the father and 'm' represent the mother. We are given that:
Replace the first two equations into the last to solve for 'f':
The father is 47 years old.

Answer: 100 revolutions</h3>
This value is approximate because pi = 22/7 is approximate.
===========================================================
Explanation:
Let's find the perimeter of the wheel, aka the circumference
C = pi*d
C = (22/7)*77
C = 242
The distance around the tire is approximately 242 cm
At first glance, it looks like one revolution will do the trick. However, we need to cover 242 meters and not 242 cm.
We can say the following
1 meter = 100 cm
242 meters = 24200 cm .... multiply both sides by 242
One revolution covers 242 cm, which is 1/100 of the distance we need to cover. So that means we need to do 100 revolutions to get to the target we're after.
1 revolution = 242 cm
100 revolutions = 24200 cm ... multiply both sides by 100
---------------------------
We could also use a proportion to solve
(1 revolution)/(242 cm) = (x revolutions)/(24200 cm)
1/242 = x/24200
1*24200 = 242x
242x = 24200
x = 24200/242
x = 100
Answer:
who would get a circular mirror? they are cursed, and reflect things wierdly. But the area is
Step-by-step explanation:
36x.
Despite it being a circular mirror, it matters the number and math words. Because of the METAL FRAME, you have to add something to fix that open area around the mirror. So the answer is 40x
Answer:
Y=2×+13
Step-by-step explanation:
2×+3=0
2×=0-3
you use 3 to divide it self =×
×=3
