Answer:
Step-by-step explanation:
Let x be the number of hours worked by Joshua.
Shirts ironed by Joshua in an hour = 25
Number of shirts ironed by Joshua in x hours = 25x
The number of hours worked by Luke = (x + 3)hours
Shirts ironed by Luke in an hour = 35
No. of shirts ironed by Luke in x hours = 35*(x + 3) = 35x+35*3 = 35x + 105
No. of shirts ironed by Luke and Joshua = 345
25x + 35x +105 = 345
60x = 345 - 105
60x = 240
x = 240/60
x = 4 hours
The number of hours worked by Joshua = 4 hours
The number of hours worked by Luke = 4 +3 = 7 hours
Answer:
.
Step-by-step explanation:
3x - y = 17 .......A
10 × [x/5 + y/2] = 10 × 0
2x + 5y = 0 .......B
......A× 5 both 2 sides of equation
15x - 5y = 85 .....C
......B + ........C
2x + 15x = 0 + 85
17x = 85
x = 85/17
x = 5
put x value in ........A or .......B or ......C
you will receive y = -2
Answer:
The least possible quotient is 125.
Step-by-step explanation:
To do this we need to find the greatest 2 digit factor of 10,000.
10,000 = 2*2*2*2*5*5*5*5
So the greatest 2 digit number which will divide exactly into 10,000 is
= 2*2*2*2*5
= 80.
This will give the smallest quotient: 10,000 / 80 = 125.
The number -6.75 is rational if it is an integer or decimal. -6.75 is a decimal, so -6.75 is rational, not irrational.
