Answer:
Step-by-step explanation:
[1] 3x - 4y = -24
[2] -x - 16y = -52
Graphic Representation of the Equations :
-4y + 3x = -24 -16y - x = -52
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -16y + 52
// Plug this in for variable x in equation [1]
[1] 3•(-16y+52) - 4y = -24
[1] - 52y = -180
// Solve equation [1] for the variable y
[1] 52y = 180
[1] y = 45/13
// By now we know this much :
x = -16y+52
y = 45/13
// Use the y value to solve for x
x = -16(45/13)+52 = -44/13
Solution :
{x,y} = {-44/13,45/13}
Answer:
x = 23/7
Step-by-step explanation:
7 x + 15 equals 38
7x+15 = 38
Subtract 15 from each side
7x+15-15 = 38-15
7x = 23
Divide each side by 7
7x/7 = 23/7
x = 23/7
Answer:
1486.67 or 1487.
Step-by-step explanation:
Find the average of those three things. Add 2,340 plus 470 plus 1650. You get 4460. Since you have three costs, divided 4460 by 3, which is 1486.6 repeating. Round to the nearest hundredth which is 1486.67. Hope this helps!
Answer:
6a+150+18c
Step-by-step explanation:
6(a+25+3c)
6a +6 x 25 +6 x 3c
6a + 150+6 x 3c
6a +150 +18c
