Answer:
5
Step-by-step explanation:
B and D are congruent. Set them equal to each other.
15x + 5 = 16x - 2
x = 7
Plug into B.
15(7) + 5 = 110
180 - 110 = 70
12y + 10 = 70
12y = 60
60 / 12 = 5 = y
Answer:
16*4+2.50
Step-by-step explanation:
Answer:
1.3
Step-by-step explanation:
⅓ put into to decimal form is a repeating decimal
Answer:
[2] x = -5y - 4
// Plug this in for variable x in equation [1]
[1] 2•(-5y-4) - 5y = 22
[1] - 15y = 30
// Solve equation [1] for the variable y
[1] 15y = - 30
[1] y = - 2
// By now we know this much :
x = -5y-4
y = -2
// Use the y value to solve for x
x = -5(-2)-4 = 6
Solution :
{x,y} = {6,-2}
