Answer:
x(less than or equal to)5
Step-by-step explanation:
add 10 to both sides
20x-10(less than or equal to) 90
+10 +10
20x (less than or equal to) 100
divide by 20 to isolate the variable
20x(less than or equal to) 100
/20 /20
x (less than or equal to) 5
Step-by-step explanation:
Did you mean :
sin(x + 75°) = sin(15°)
x + 75° = 15°
x = 15° - 75°
x = -60°
Do you have to simplify? if you do it's -30K+42
Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.
Given that Y varies directly with X, and Y = 15 and X = 5, if we introduce a constant of proportionality, k, the expression becomes
15 = 5k
k = 15/5
k = 3
The equation would be
Y = 3X
Therefore, when X = 9, the value of Y would be
Y = 3 × 9
Y = 27
