Answer:
−10x + 4.35xy + 55y + 9.58
Step-by-step explanation:
Step 1: Collect like terms.
(6x − 16x) + 4.35xy + (16y + 39y) + 9.58
Step 2: Simplify and you're done!
−10x + 4.35xy + 55y + 9.58

Answer: C
Step-by-step explanation:
Answer:
Part A: 272 teenagers surveyed like hard rock.
Part B: 200 is the total number of teenagers that Damian surveyed.
Part C: Polly surveyed 850 teenagers to find out their favorite type of music. She found that 132% of the teenagers surveyed like hard rock.
Step-by-step explanation:
Part A: % = 1/100, 32% = 32/100, so 32% of 850 is
32/100 x 850 = 272.
Part B: if Total is T, then 75% of T is = 150, i.e,
75/100 x T = 150, making T subject of relation, then T, Total = 200.
