Answer:
3 miles and then 3 per mile for each additional mile
Answer:
y should be 5, when u solve for the angles u get 68+87+c=180, if c is y^2 then y is 5
Step-by-step explanation:
Answer:
-6 = m (i'll show my work below)
Step-by-step explanation:
-6(m-7) + 7 = -8m + 37
-6m + 42 + 7 = -8m + 37
-6m + 49 = -8m +37
-37 = -37
-6m + 12 = -8m
+6m = +6m
12 = -2m
/-2 = /-2
-6 = m
Answer:
45 sq.units
Step-by-step explanation:
to get area of a triangle, it would be base*height/2, so 15*6/2 would be 90/2, which ends up being 45, which is the answer.
Answer:
Present age
Son: 15
Father: 45
Step-by-step explanation:
Remark
Thank you for the translation. Without it, the problem would be impossible -- at least for me.

Let the present age of the father = x
Let the present age of the son = y
Solution
x + y = 60
How many years will pass? You could say it's z.
x + z = y When z years pass, the son will be his father's present age.
x + z + y + z = 120 when z is added to both their current ages, the result is 120 Collect like terms
x + y + 2z = 120
<u>x + y = 60 </u> Subtract The very first equation
2z = 60 Divide by 2
z = 60/2 30 years have passed.
z = 30
x + z = y
x + 30 = y Substitute x + 30 for the present y value (the father).
x + x + 30 = 60
2x = 30
x = 15
x + y = 60
15 + y = 60
y = 60 - 15
y = 45
So the son's age right now is 15
The father's age right now is 45
