Answer:
x = -6
Step-by-step explanation:
So marked down 10 then 12 so 10+12=22
mark down total is 22%
100-22=78
78% of 109=0.78 times 109=85.02
tax of 6%
6+100=106%
85.02 times 1.06=90.1212 or about 90.12
90<90.12
no she is short 12 cents
The number of Euros received against 600 dollars = 450
Then
For 1 dollar, the number of euros = (450/600) euros
= (45/60) euros
= ( 3/4) euros
= 0.75 euros
So the unit rate that describes the exchange rate is 0.75 euros per dollar. So the correct option among all the options given in the question is option "A".
I hope the procedure for
getting to the correct result is clear enough for you to understand. In future
you can use this procedure for solving similar problems.
Answer:
Step-by-step explanation:
A possible word problem for 3x+10 ≤75 could be
Mat has $75 dollars saved in his wallet and wants to use it for go carts. Knowing that the entrance to the park is $10, and each time around the go cart course is $3 what is the maximum times he can go around?
3x+10 ≤ 75, subtract 10 from both sides
3x ≤ 75-10, divide both sides by 3
x ≤ 65/3
or x ≤ 21.(6)
So it can go around 21 times the most.
4x(-2) + 4 x 7 4x5 + 2x(-1) =[-8 20]
[28 -2 ]
