Answer:
a=9
Step-by-step explanation:
2/3 (a-18)=-6
a−18=−6×( 3/2)
a−18=−6×3/2
a−18= −18/2
a−18=−9
a=−9+18
a=9
Answer:
1/6feet
Step-by-step explanation:
Given
Point A on the island = -7/3 feet from the sea surface
Point B on the island = -5/2 from the sea surface
The distance between the two points will be Point A - Point B
Distance between the two points = -7/3 - (-5/2)
= -7/3+5/2
Find the LCM
= {2(-7)+3(5)}/6
= -14+15/6
= 1/6
Hence the distance of the two points from the surface of the sea is 1/6feet
101 ÷ 5 = 20 with a remainder of 1
So 20 is your whole number and 1 becomes your numerator and 5 remains your denominator.
20 1/5

Answer:
The correct answer is A. Milk has about 1/3 as many hydrogen ions as lemon juice.
Step-by-step explanation:
Given that the PH indicates the amount of hydrogen ions present in a certain solution, and that, the higher the PH, the lower this amount will be, if the milk has a PH of 6 and the lemon has a PH of 2, to calculate the respect correct, the following calculation must be performed:
2/6 = 1/3 = 0.333
Therefore, milk has about 1/3 as many hydrogen ions as lemon juice.
