Answer:
31
Step-by-step explanation:
3x + 12 and 105 are alternate exterior angles because A || B and B || C.
If the two or more lines are parallel, then the alternate exterior angles are equal.
3x + 12 = 105
Substract 12 on both sides,
3x = 105 - 12
3x = 93
Divide 3 on both sides,
x = 93 / 3
x = 31
Answer:
<u>c. no solution</u>
Step-by-step explanation:
This system of equations has no solution because when graphed, the lines are parallel to each other. Meaning they will never intersect. Since they will never intersect, there are no solutions.
You have to find a common denominator first.
Answer:
the coefficients are 4 and 5 and 1
Step-by-step explanation:
the 4 and 5 have a variable in front of them. There's a ghost 1 in front of the x, because it's value is 1 times whatever the value of x is
100 lbs = 1 lb of melon 99 lb water
Let "x" be weight of water:
percentage = weight of water / (1 lb melon + water)
.98 = x / (1 lb melon + x)
.98 = x / 1 +x
.98 + .98x = x
.98 = .02x
x = 49
49 lbs of water
1 lb melon + 49 lbs water = 50 lbs total
49 / 50 = 98%
Therefore, 50 POUNDS of water evaporated
