Answer:
Step-by-step explanation:
Givens
Let the number in the Spanish Class = x
Then the number in the Geometry Class = (4/5) x
Equation
x + (4/5)x < 54
Solution
x + (4/5)x < 54
4/5 = 0.8
x + 0.8x < 54
1.8x < 54 Divide both sides by 1.8
1.8x / 1.8 < 54/1.8
x < 30
The sign used in the equation is less than, not less than or equal to.
The number of students taking Spanish cannot equal 30. There must be 29 in the Spanish Class.
Answer:
2/3
Step-by-step explanation:
2 - 1 1/3 = 2/3
First convert 4 cms to mms by multiplying by 10
then divide this by number of days in a year (365)
so R = 10*4 / 365
= 0.109589 mm / day
