To find the total combinations multiply each quantity together:
5 x 4 x 3 = 60
Answer: 60 different ways
58.50
10%= 4.50
5%= 2.25
6.75*2= 13.50
45+ 13.50= 58.50
Answer:
I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Answer:
x = -13, y = -3
Step-by-step explanation:
let a number = x; the other = y
x = 3y - 4
x + y = -16
Isolate the y in the second equation. Subtract x from both sides
x (-x) + y = -16 (-x)
y = -16 - x
Plug in -16 - x for y
x = 3(-16 - x) - 4
Simplify. Distribute 3 to all terms within the parenthesis
x = -3x - 48 - 4
x = -3x - 52
Isolate the x. Add 3x to both sides
x (+3x) = -3x (+3x) - 52
4x = -52
Divide 4 from both sides
(4x)/4 = (-52)/4
x = -52/4
x = -13
Plug in -13 for x in one of the equations:
x + y = -16
(-13) + y = -16
Isolate the x. Add 13 to both sides
y - 13 (+13) = -16 (+13)
y = -16 + 13
y = -3
Answers: x = -13, y = -3
