Answer:
Step-by-step explanation:
1.
Replace with ; solve
Therefore,
Replace with
Therefore,
2.
Replace n with 10; solve
Ann: 21
Jim: 31
Miguel: 63
Let’s start by finding Ann’s number.
a + (a + 10) + 3a = 115
5a + 10 = 115
5a = 115 - 10
5a = 105
a = 105 / 5
a = 21
Now, just find the others’ numbers using Ann’s.
Jim sent ten more messages than Ann, and 21 + 10 = 31.
Miguel sent 3 times as many messages as Ann, and 21 * 3 = 63.
The solution is (4,10)
Option C is correct.
Step-by-step explanation:
We need to graph the system of equations.
The equations given are:
We need to solve the equations to find value of x and y
We can solve these using substitution
Let:
Putting value of y from eq(2) into eq(1)
So, value of x = 4
Now, Put value of x in eq(2)
So, Value of y = 10
The graph is shown in figure attached.
The solution is (4,10)
Option C is correct.
