Well, if we divide 150 by 5 to see how much each individual part is, we get 30. To find out how much Lora got, we need to multiply 30 by 4, which is 120. Altogether, they got 120 plus 150, which is $270.
Answer: y=3
Step-by-step explanation: y would be 3 because in the problem, x is being multiplied,so to do the inverse, you'd need to divide. 6 divided by 2 is 3.
Answer:
A. {x,y}={-2,-3}
// Solve equation [2] for the variable x
[2] x = 2y + 4
// Plug this in for variable x in equation [1]
[1] (2y+4) - y = 1
[1] y = -3
// Solve equation [1] for the variable y
[1] y = - 3
// By now we know this much :
x = 2y+4
y = -3
// Use the y value to solve for x
x = 2(-3)+4 = -2
B. [1] 3x=3y-6
[2] y=x+2
Equations Simplified or Rearranged :
[1] 3x - 3y = -6
[2] -x + y = 2
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = x + 2
// Plug this in for variable y in equation [1]
[1] 3x - 3•(x +2) = -6
[1] 0 = 0 => Infinitely many solutions

System of Linear Equations entered :
[1] 4x - y = 2
[2] 8x - 2y = 4
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 4x - 2
// Plug this in for variable y in equation [2]
[2] 8x - 2•(4x-2) = 4
[2] 0 = 0 => Infinitely many solutions
The answer is b because the slope is 2 and the y intercept is 9
Answer:
x=-41/14
Step-by-step explanation:
7(2x+6)=1
14x+42=1
14x=-41
14x/14 -41/14
x=-41/14
