Freddy is 4 years older than 8 times his grandson's age. the sum of their ages is greater than 67. what is the youngest age freddy's grandson can be? enter your answer, as a whole number, in the box.

If you translate the description into an equation with F=Freddy and G=grandson, it will be:
1. F = 8G+4
2. F+G> 67

Then if you put the first equation into second equation, it would be:
(8G+4) +G>67
9G>67-4
G>63/9
G>7

Then the answer for how much youngest age of Freddy's grandson age would be 7 years

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
