|x|=absoulte value of x which means whatever x is, make it positive
so first solve any division/multiplication
the only one is 12/46=6/23
so we do the absoulte value signs
-3+45-(-14)
-(-14)=+14
-3+45+14=56
absoulute value of 56=56
56+(-|-87+6/23|)
-87+6/23=-86 and 17/23
absoulte value of -86 and 17/23=86 and 17/23
there is a negative sign in front of the absoulte vaulue so make it negative
56-86 and 17/23=-30 and 17/23 or about -30.73913
Answer:
5
Step-by-step explanation:
You save ⅓ of entry fee, so you save 1.20 and you pay 2.40. We only really care about the 1.20 reduction. 5 / 1.2 = 4.16 so he must go 5 times to get the 5 back
Answer:
110 have a good one
Step-by-step explanation:
22x5 is 110
Answer:
at least 4674 flags should be sold to show a profit
Step-by-step explanation:
The net profit is defined as the revenue (income from selling the flags) minus the cost (of producing the flags).
Since we want that profit (P) to be larger than zero, we want the Revenue (R) to be larger than the cost (C):
P = R - C
we want P > 0 (zero) then we want: R - C > 0 which means R > C
We can now replace R and C by their expressions in terms of x (the number of flags produced):
36 x > 32 x + 18695
we subtract 32 x from both sides to gather all terms in the variable "x" on the left hand side of the equation:
36 x - 32 x > 18695
4 x > 18695
Now we solve for x by dividing both sides by 4 (thus isolating the unknown x):
x > 18695 / 4
x > 4673.75
Therefore x must be at least the following integer to 4673.75, that is : 4674
