Answer:
We get x=3 and y=21
The ordered pair will be: (3,21)
Step-by-step explanation:
We need to use the substitution method to solve the system of equations.
For substitution method we substitute the value of x or y from one equation to other.
Let:
Putting value of y from equation 2 into equation 1
So, we get value of x=3
Now, for finding value of y, We substitute the value of x
Find value of x from equation 2
Now, putting value of x in equation 1
So, we get value of y=21
So, We get x=3 and y=21
The ordered pair will be: (3,21)
Answer:
b=60
Step-by-step explanation:
6+4/5b=9/10b
-4/5b -4/5b
6=1/10b
divide both sides by 1/10
b=60
(y + z2) * x
(5 + 3(2)) * 2
(5 + 6) * 2
11 * 2
Your answer is 22

Answer:
15.60
Step-by-step explanation:
The sub total before tax is 34.95. You know the socks cost 3.75 and the skirt and shoes are the same or equal price. This means after subtracting the cost of the socks, you spent 34.95 - 3.75 = 31.20. Since the skirt and shoes cost the same, divide 31.20 by 2. This is $15.60.
