X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7
x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19
The sides are 12, 14, and 19 cm. long. Hope this helped!
Answer: Choice A) 3x+4y = 12
---------------------------------------------------------------------
y = (-3/4)x + 3
4*y = 4*((-3/4)x+3) ... multiply both sides by 4 to clear out the fraction
4y = -3x+12 ... distribute and multiply
4y+3x = -3x+12+3x ... add 3x to both sides
3x+4y = 12
Note: this is in standard form Ax+By = C where A = 3, B = 4 and C = 12.
Answer:
y= -5
Step-by-step explanation:
-3(4) +9y = 57
-12 + 9y = 57
-12 + 12 + 9y = 57 + 12
9y/9 = -45
y= -5
Answer:
A. Term
Step-by-step explanation:
A constant does not cointain a variable, a variable by itself does not contain a constant.
It's a term because it has a constant and a variable.
