Answer:
x = 1
Step-by-step explanation:
4x-5=y
4x-5= -1
4x = -1+5
4x=4
x=1
2x-y=3
2x-(-1)=3
2x+1=3
2x= 3-1
2x= 2
x=1
since the two answers for x are the same therefore:
x = 1
Answer:
The answer is 2
Step-by-step explanation:
sin60°+ 2 tan45° - cos30°
sin60° = √3/2
2 tan45° = 1
cos30° = √3/2
sin60°+ 2 tan45° - cos30°
√3/2 + 2(1) - √3/2
√3/2 - √3/2 + 2(1)
0 + 2 = 2
Thus, The answer is 2

Answer:
We have 10 sections, we can assume that the probability of hitting each of one of them is the same.
we have 9 grey slices and 1 white slice, then the probability of landing in a grey slice is equal to the number of grey slices divided by the total number of slices:
P(X) = 9/10 = 0.90
The probability of not landing in a grey slice is equal to the probability of landing in the white slice, this is:
P(not X) = 1/10 = 0.10
Also, when you have only two events, you can calculate this as:
P(not X) = 1 - P(X) = 1 - 0.90 = 0.10
Answer:
2
Step-by-step explanation:
Find the greatest common factor of 8, 18, and 70.
Since we are looking for the Greatest Common Factor of the numbers given, we begin by factoring the numbers. It is usually easiest to start with the smallest number. Also, if there is a number that has obvious factors. In our case, satisfies both of these:
8=2⋅2⋅2 In fact,
8 only has one unique factor! If there is to be a common factor (other than
1 ) it must be
2. We now need to check that both
18 and 70 have 2 as a factor:
18=2⋅9
70=2⋅35 Therefore, 2 is the GCF of 8, 18 and 70.
