Answer:
the ordered pair is (2,-1)
Step-by-step explanation:
We need to solve the system of equations using elimination method
12x - y = 25 eq(1)
9x + y = 17 eq(2)
Adding eq(1) and eq(2)
12x - y = 25
9x + y = 17
___________
21x = 42
x = 42/21
x= 2
Now, putting value of x in equation 1
12x - y = 25
12(2) -y = 25
24 -y = 25
Adding -24 on both sides
24 -y-24 = 25-24
-y = 25-24
-y = 1
Multiply both sides by -1
y = -1
the value of x = 2 and y = -1
So, the ordered pair is (2,-1)
2.53 is then answer .... im pretty sure
Answer:
If the lines that forms < X are perpendicular, it can be assumed that it is a right angle.
Step-by-step explanation:
An indirect proof of an angle is an assumption about the value of the angle that can be made by mere inspection and some considerations.
< X = right angle = 
A right angle is one that is equal to . As an indirect proof, if the lines that forms the angle are perpendicular; then it can be assumed to be a right angle. Because perpendicular lines are at right angle to one another.
Answer:
i think that it would be
$370.85
Step-by-step explanation:
The following expression shows the amount of money in the account after x weeks.
If $20.50 was added to the account for 10 weeks we can substitue 10 as the x:
$370.85 will be in the account after 10 weeks
Answer:
Diego Would Have $120
How I Found The Answer:
10% Of $80 = $8
$8 x 5 = $40
$80 + $40 = $120
