Ok, so after you do -8a+5a, you also have to do 6 -35, getting the equation
-29-3a
Alright.
So, we have 2185 student in Rose.
Lily School has 307 more students than Rose, so Lily has,
2185 + 307 = 2492 Students in Lily School.
Since question a. is asking you to round off to the nearest ten, your answer to part a is 2490.
For part b. add 2185 and 2490.
2185 + 2490 = 4675 students.
The questions want you to round to the nearest hundredth, so,
4700 is the answer to part b.
Answer:
709,007
Step-by-step explanation:
Look at the place values.
In 700, 000, the thousands column is in the third digit. Therefore add nine to that place.
In 700, 000 the ones column is the last digit. So add 7 to that place.
Answer:

Step-by-step explanation:
Given
Empty Tank

When filled with water, the height is:

Required
Determine how many more cubic inches needed
First, we calculate the difference between the height of the tank and the height of the water.


The volume of water to full the tank is then calculated as:



The solution for the given equations x + 3y = 5 and x - 3y = -1 are x=2 and y=1.
Step-by-step explanation:
The given is,
......................................(1)
....................................(2)
Step:1
By elimination method,
Subtracting Equations (1) and (2),


( - )
(
) + (
) = (
)
= 6
= 1
Step:2
Substitute the value of y in equation (1),

+ ( 3 × 1 ) = 5
= 5-3
= 2
Step:3
Check for Solution,
Substitute the values of x and y in Eqn (1),

2 + ( 3 × 1 ) = 5
5 = 5
Result:
The solution for the given equations x + 3y = 5 and x - 3y = -1 are x=2 and y=1, by elimination method.
