Step-by-step explanation:
a÷b=960÷89=10.78651685=10.79 or 17.8
5 of the 6 exits were men, so the experimental probability that a man exits the room is 5/6.
Answers are like this: 1)Cos C 2)Cos B 3)Cos A 4)a 5)b 6)c all of them are different type of writing cosines law , just this.
The pair of equations:
y = x + 4
y = -2x - 2
To solve the system of equation by substitution, you would substitute one variable for it's equivalent expression. Combining the pair of equations into one equation in only one variable. The easiest way to do this is by substituting out the variable y because it is already alone on one side of the equal sign. Substitute the y in the second equation for: x+4
x+4 = -2x - 2
solve for x
x + 2x = -2 -4
3x = -6
x = -2
now use the value for x to find y by putting into either equation.
y = x + 4
y = (-2) + 4
y = 2
solution is: (-2, 2)
Answer:
Step-by-step explanation:
If she can husk 8 in 24mins
⟩ 8 = 24
Let x = ears of corn in 33mins
⟩ 8 = 24
x = 33
If less more divide
⟩ 24x = 8×33
⟩ x = 264÷24
⟩ x = 11 mins
