Answer: A. (3,-2)
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 4x = 5y + 22
[2] x = 5y/4 + 11/2
// Plug this in for variable x in equation [1]
[1] 2•(5y/4+11/2) + 5y = -4
[1] 15y/2 = -15
[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+11/2
y = -2
// Use the y value to solve for x
x = (5/4)(-2)+11/2 = 3
Solution :
{x,y} = {3,-2}
Answer:

Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
Hence,

Remove brackets:


Subtract 22 from both sides:


2782 is the answer my friend
Hi there, a quotient is the answer of a division problem. For example, 2÷2=1, 1 is the quotient. A remainder is a number that is left over in a division problem. For example, 7÷2=3 R1, R1 is remainder of 1.
Answer:
B is correct
Step-by-step explanation:
These are Absolute Value expressions. (How far from 0 on the number line) So disregard negative or positive signs. The only true statement would be 2<4.
