4.5(8 - x) + 36 = 102 - 2.5(3x + 24)
36 - 4.5x + 36 = 102 - 7.5x - 60
72 - 4.5x = 42 - 7.5x
-4.5x + 7.5x = 42 - 72
3x = - 30
x = -30/3
x = -10 <===
Hope this helps!
Answer:
She realised $12 from selling 8 bags of caramel corn
Step-by-step explanation:
Given
(8, 12)
Required
Determine what it means based on the available information
A function is always written as (x,y)
Where x is dependent on y
By comparison,
x = bags of caramel corn = 8
y = amount realised = 12
Assuming the currency is in dollars
Conclusively,
She realised $12 from selling 8 bags of caramel corn.
Answer:
Step-by-step explanation:
50 dollars = ∉34
∉1 = Rs 150
Rs 382800 / 150 Rs per ∉ = 382800/150 ∉
=2552 ∉
50 dollars = ∉34 so 50/34 dollars = ∉
2552 ∉ × 50/34 dollar per ∉ = in the units the ∉ cancel out
∉ × dollar/∉ = dollars
(2552 × 50) / 34 = 3752.94 dollars <------------------
Here is another way of looking at the answer...........
Rs 382800 × 1∉/150 Rs × 50 dollars/34 ∉ = note how the units cancel
= 382800 × (1/150) × (50/34) Rs × ∉/Rs × dollars/∉
= 3,752.94 dollars leaving only dollars in the numerator
The mean, median, and mode are equal to 1. So among the choices, the first one is correct - mean = mode
Mean - an <em>average </em>of the given set of number; to find this, add the numbers and divide it by 11 (the number of given data)
= (-1 + -1 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3) / 11
= 1
Median - the <em>middle or center</em> of the given set; to find this, arrange the numbers in numerical order, then get the center or middle number as the median
= <span>-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
= [</span><span>-1, -1, 0, 1, 1,] <u>1</u>, [1, 2, 2, 2, 3]
Mode - is the value that occurs most of the time in the given set; so obviously <em>number 1 occurred four times</em> so 1 is our mode
