Answer:
12x - 15 dollars
Step-by-step explanation:
Sunny earns $12 per hour for delivering cakes.
She worked for x hours this week.
Unfortunately, she was charged $15 for a late delivery on Tuesday
She was supposed to earn $12 × x = $12x this week
But she was charged $15 for late delivery on Tuesday
So her net earning this week is; $12x - $15
Answer:
-(18/49)=n or approximately n=-0.367
Step-by-step explanation:
our equation is: m(nx²-y)/z=5n in order to find n we need to substitute the values given in the question. when we substitute we get:
6*(n*(-2)²-(-3))/(-5)=5n
6(4n+3)/(-5)=5n (we distribute the 6 in the numerator)
24n+18/-5=5n (we multiply both sides by (-5))
24n+18=-25n (we subtract 24n from both sides)
18=-49n (divide both sides by (-49))
-(18/49)=n or approximately n=-0.367
<h3><u>Solution:- </u></h3>
Let the number to be added be A
Now,
Transposing (−5x³+ 4x − 3 ) to other side-
Remember if there is a -ve sign before a bracket the signs of whole of the terms changes on opening bracket
Putting like terms together -
Therefore, 5x³+x²-5x +2 should be added to −5x³+ 4x − 3 to get x²− x − 1
In one revolution of the wheel, a point on the edge travels a distance equal to the circumference of the wheel.
The wheel has radius 1 ft, so its circumference is 2π (1 ft) = 2π ft.
Then the point has a linear speed of
(1/4 rev/s) * (2π ft/rev) = 2π/4 ft/s = π/2 ft/s
Two divided by three is 0.6666 repeating.
