Answer:
18, -3
using the formula for midpoint M=(x1+x2)/2 ,(y1+y2)/2
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
Three hundred and eightteen and twentyfive meters
Answer:
There is no sign you can not figure it out
Step-by-step explanation:
Answer: K= -7, 15
Step-by-step explanation: if the distance between J and K is 11 and it is on number line, then you simply move 11 in the positive and negative direction and that will be your answer... hope it's right!!
