8. complementary angles = 90°
3x+3+10x-4 = 90
13x-1 = 90
13x = 91
so x = 91/13= 7
then K = 3(7)+3 = 24°
so L = 10(7)-4 = 70-4 = 66°
9. P is three less than twice of Q
so P = 2Q-3
supplementary angles = 180°
P+Q = 180
(2Q-3)+Q = 180
3Q-3 = 180
3Q = 183
so Q = 183/3 = 61°
then P= 2(61)-3 = 122-3 = 119°
10. B is two more than three times of C so B= 3C+2
complementary angles = 90°
B+C= 90
(3C+2)+C=90
4C+2=90
4C= 88
so C= 22°
then B = 3(22)+2= 66+2 = 68°
Answer: Stop and Save is better
Step-by-step explanation:
you can get 3 apple at Quick market for $1.20, but you can buy 5 at Stop and Save for only 5 cents more, plus your getting two more apples.
Original Coordinates: (-2, -8) (-6, -8) (-11, -1) (-7, -3)
A 180 degree rotation around the origin flips the signs of x and y, so you get:
(2, 8) (6, 8) (11, 1) (7, 3)
Then a translation to the left 6 units just subtracts 6 from all the x values:
(-4, 8) (0, 8) (5, 1) (1, 3)
Those are your points! Hope this helped!
-7, -4/5, 0, 1/2, 7/8, and 2
Answer:
Rs. 80
Step-by-step explanation:
Given that :
Purchase price = 70
Profit = 6
Discount = 5%
Let selling price = x
Selling price * (1 - discount) = (purchase price + profit)
x * (1 - 5%) = (70 + 6)
x * (1 - 0.05) = 76
x * 0.95 = 76
0.95x = 76
x = 76 / 0.95
x = 80
Hence, selling price = Rs. 80
