Answer will be
Step-by-step explanation:
We have to perform the calculation without changing into decimal
can be written as
So
Now taking common
It is given in the statement that the increase in number of scones is same from Robbie till Charlie.
Let us assume that Robbie buy x scones and every boy buys y more scones than the previous ones.
The number of scones for each of the boy can be written as:
Robbie = x
Cameron = x + y
Louis = x + 2y
Tom = x + 3y
Charlie = x + 4y
Total number of scones = 60
So,
Robbie and Cameron's combined total number of scones is three sevenths of the total of Louis, Tom and Charlie. Mathematically this can be stated as:
Using Solving the two equations simultaneously:
This means, Robbie buys 8 scones,
Cameron buys 8 + 2 = 10 scones,
Louis buys 8 + 4 = 12 scones,
Tom buys 8 + 6 = 14 scones,
and Charlie buys 8 + 8 = 16 scones
Answer:
1) 5°: 5 is halfway from 0 and 10
2) 5°: 5 is halfway through -5 and 15
3)-5°: -5 is halfway through 5 and -15
4)0°: 0 is halfway through -8 and 8
1) simplify 2^3 to 8
8+3^2-10
2) simplify 3^2 to 9
8+9-10
3) simplify 8+9 to 17
17-10
4) simplify
7
