A) let h = number of half page ads and f = number of full page ads
40h + 75f = 800. Assuming budget is fully spent
h + f = 13
B) 75h + 75f = 975 (multiplying the second equation by 75)
35h = 175 (subtracting the first equation)
h = 5
Michael purchases 5 half page adverts
C) 5 + f = 13 (Substituting for h in second equation)
f = 8
Michael purchases 8 full page adverts
Answer:
∠RST = 4x - 6
Step-by-step explanation:
Since SQ bisects ∠RST then
∠RSQ = ∠QST = 2x - 3 and
∠RST = ∠RSQ + ∠QST = 2x - 3 + 2x - 3 = 4x - 6
Answer:
x equals to -1
Step-by-step explanation:
x-4x :3
-3x : 3
so x: -1
