Step-by-step explanation:
By the Distributive Property,
2/5 * (15x - 10)
= (2/5)(15x) + (2/5)(-10)
= 6x - 4.
Answer:
Distance = 3.15 miles
Step-by-step explanation:
<u><em>Given:</em></u>
Speed = 4.2 mph
Time = 45 mins = 0.75 hr
<u><em>Required:</em></u>
Distance = ?
<u><em>Solution:</em></u>
Distance = Speed * Time
Distance = 4.2 * 0.75
Distance = 3.15 miles
Answer:
A
Step-by-step explanation:
∠ AOC = 90° and
∠ AOB + ∠ BOC = ∠ AOC , that is
x + 8 + 2x = 90
3x + 8 = 90 ( subtract 8 from both sides )
3x = 82 ( divide both sides by 3 )
x =
Then
∠ BOC = 2x = 2 × = ≈ 54.67° ( to 2 dec. places )
Answer:
12 - 6 x (0 + 15) = 34
How I got my answer
First, how i got my answer was that I had to solve the equation first, ignoring the answer. I got 0 x 6 = 0, then I did 124 - 0 = 124, then I did 124 - 15 = 109, which clearly isn't 34. I figured that we have to put the parentheses around the zero because if we don't, we are going have to multiply something by zero, which always gets zero. After that, I decided that I should put the parentheses around either the 6, or the 15. I did both, and saw which one was correct. If we put it around the 6, we get, 124 - (6 x 0) + 15 = 124 - 0 - 15 = 124 - 15 = 109, which isn't 34. Then I checked 124 - 6 x (0 + 15) = 124 - 6 x 15 = 124 - 90 = 34, and we just got the answer.
P.S. Sorry if it was confusing, I didn't really know how to explain it
