Answer:
5x-6+7x+12=180
Step-by-step explanation:
5x+7x = 12x
12x - 6 +12 = 180
add 12 and -6 to get 6.
12x + 6 = 180
subtract 6 from both sides to get 174.
12x = 174.
now divide both sides by 12 to get x = 14.5 or 29/2 which cancels out to 6
Answer:
B several
Step-by-step explanation:
The solutions are where the graphs intersect
It appears there are 3 points of intersection
Given the choices
It is more than one and less than infinite
3x^2y^4z - 6xy - 3z(5x^2) has three terms.
I'm just guessing because there isn't much data, but the ages could be:
1, 8, and 9
3, 3, and 8
1, 8, and 9
1, 6, and 12
2, 3, and 12
3, 4, and 6
2, 4, and 9
(These aren't all the possible ages)
