Hey there,
Answer:
Rate = Distance / Time
= 875.52km / 38.4 hrs
= 22.8km / hr
Hope this helps :D

To solve this, you can set up an equation. Make the length of the shortest side x, so the 2 sides double the length will equal 2x. Since they all equal the perimeter of 36, do x + 2x + 2x =36. These values all represent the sides(2 longer, one short). Combine like terms to get 5x=36 then divide by 5 to find the value of x. x=7.2in meaning the shorter side is 7.2 inches while the longer sides are both 14.4 inches each since they are double in size.
Answer:
x = - 33
Step-by-step explanation:
Given
(x + 6) = - 18
Multiply both sides by 3 to clear the fraction
2(x + 6) = - 54 ( divide both sides by 2 )
x + 6 = - 27 ( subtract 6 from both sides )
x = - 33
it’s basically just any number that can be multiplied with another to get a new expression
Answer:
angles 1, 3, 6, 8 = 142°
angles 2, 4, 5, 7 = 38°
Step-by-step explanation:
Vertical angles and corresponding angles are congruent, as are alternate interior angles. Hence the angles 1, 3, 6, 8 are all congruent:
∠1 = ∠3 = ∠6 = ∠8 = 142°
Each of the remaining angles forms a linear pair with one or another of those, so is its supplement:
∠2 = ∠4 = ∠5 = ∠7 = 180° -142° = 38°
