Hopefully these are correct lol, make sure to check it with a classmate. but i tried :)
Answer:
80°
Step-by-step explanation:
Let the angle be x then four times it's complement plus 60, that is
4(90 - x) + 60 ← is it's supplement
Supplementary angles sum to 180°
Sum the angle and it's supplement and equate to 180
x + 4(90 - x) + 60 = 180 ← distribute and simplify left side
x + 360 - 4x + 60 = 180
- 3x + 420 = 180 ( subtract 420 from both sides )
- 3x = - 240 ( divide both sides by - 3 )
x = 80
The required angle = x = 80°
supplement = 4(90 - 80) + 60 = 4 × 10 + 60 = 40 + 60 = 100°
Answer:
Step-by-step explanation:
Adam plans to choose a video game from a section of the store where everything is 75% off.
The expression written by him for this situation is d - 0.75d.
Here, the part d represents the sale price before discount and the part 0.75d is the discount amount.
The expression written by Rena is 0.25d.
Here, the part 0.25d is the price after discount. Since 75% is the discount, the rate after disount is 25% and 25% of d is 0.25d.
Answer:
None of these answers
Step-by-step explanation:
Plug the points into the equation to see if they make sense
(4,-10), -10=3(4)+2, -10=12+2, -10=14. Incorrect
(10,-4). -4=3(10)+2, -4=30+2, -4=32. Incorrect
(-10,-4), -4=3(-10)+2, -4=-30+2, -4=-28. Incorrect
Therefore, the answer is none of these answers
