13/52= 1/4 or .25
If you have a scientific calculator it really helps with simplifying numbers to the lowest term.
Answer:
.125
Step-by-step explanation:
Answer: £76.50
Step-by-step explanation:
You find 10% of 85 = 8.5
then you do £85-£8.50 = 76.50
Question 1:
For this case, the first thing we must do is define variables.
We have then:
x: number of nickels
y: number of dimes
We write the system of equations that adapts to the problem.
We have then:
0.05x + 0.10y = 6.10
x + y = 67
Solving the system we have:
x = 12
y = 55
Answer:
there are 12 nickels
Question 2:
For this case, the first thing we must do is define variables.
We have then:
x: Allan's score
y: Dave's score
We write the system of equations that adapts to the problem.
We have then:
x + y = 375
x = 2y-60
Solving the system we have:
x = 230
y = 145
Answer:
Dave: 145 Allan: 230
Answer:
y>=1*x+2
Step-by-step explanation:
y>=k*x+n
we know that 2=k+n and 0=-2k+n
so 4=2k+n and 0=-2k+n
now 4=2n so n=2
now k=1
so y>=1*x+2
