276 - 35d
276 = total pages
35 = pages read per day
35D = number of pages she has read during D days
This is a working backwards question.
Since the golf ball was 45g, and the bag was 1.8kg,we need to make them the same units.
45g= 0.45kg
1.8kg= 1.8kg
Now that the units are the same, we put it in a calculator.
1.8÷0.45= 4
Therefore, there are 4 golf balls in the bags.
We can check this by doing 4×0.45= 1.8
Hope this helped!
Discriminant = sq root (-17^2 -4*3*10)
discriminant = sq root (289 -120)
discriminant = sq root (169)
The discriminant is positive so the equation will have 2 rational solutions.
10 less than 95
that is 95 - 10

5x + 10y = 800
y = 50
10y = 10*50 = 500
800 - 500 = 300
300/5 = 60
x = 60
5(60) + 10(50) = 800
60 small vehicles were washed in total
