24,10,26. Basically if you multiply each of the sides by the same number, (I multiplied everything by 2) then that will keep the ratios the same. You should be able to multiply each side by any number, but two will usually be the easiest

ankoles [38]

Step-by-step explanation:

Hi, there!!

Here according to the question we must find the cost of 1 kg sugar.

Given that:

17/4 kg of sugar cost £68.

then 1 kg sugar costs,

= $\frac{68}{ \frac{17}{4} }$ 

after reciprocal we get,

= £68×4/17

=£16

Danielle works as a cashier in a book store.she works 35 hours a week and earns $11 an hour.Each week Danielle spends $300 and s

OLga [1]

She earns $385 a week
35 x 11= 385

if she spends 300 shes left with 85 dollars

now if we count the 300 dollars in our estimation
385 x 4= 1,540 so she earns a 1,540 a month

1,540 x 12= 18,480
so this means she earns right around $18,480 a year

If we don't include the 300 she would earn
85 x 4= 340 a month

340 x 12= 4,080 a year

i hope this helps XD

8. The speed of the current in a river is 6 mph. A ferry operator who works that part of the river is looking to buy a new boat

Natali [406]

Answer: the speed of the boat on the lake is 9 mph
Step-by-step explanation:
Let x represent the speed of the boat on the lake or in still water.
The speed of the current in a river is 6 mph. This means that if the boat goes upstream against the speed of the current, its total speed would be (x - 6)mph. If the boat goes downstream against the speed of the current, its total speed would be (x + 6)mph.
Time = distance/ speed
Every day, his route takes him 22.5 miles each way against the current and back to his dock, and he needs to make this trip in a total of 9 hours. This means that the time taken to travel upstream is
22.5/(x - 6). The time taken to travel downstream is
22.5/(x + 6)
Since the total time is 9 hours, it means that
22.5/(x - 6) = 22.5/(x + 6)
Cross multiplying, it becomes
22.5(x + 6) + 22.5(x - 6) = 9
Multiplying through by (x + 6)(x - 6), it becomes
22.5(x - 6) + 22.5(x + 6) = 9[(x + 6)(x - 6)]
22.5x - 135 + 22.5x + 135 = 9(x² - 6x + 6x - 36)
22.5x + 22.5x = 9x² - 324
9x² - 45x - 324 = 0
Dividing through by 9, it becomes
x² - 5x - 36 = 0
x² + 4x - 9x - 36 = 0
x(x + 4) - 9(x + 4) = 0
x - 9 = 0 or x + 4 = 0
x = 9 or x = - 4
Since the speed cannot be negative, then x = 9
