Answer:
the first number is 5 the second number is 4
Step-by-step explanation:
first number = x
second number = y
X+2y=13 given this isolate x x = 13-2y
2x+y=14 substitute 13-2y for x
2(13-2y)+y=14
26-4y+y=14
-3y=-12
y=4 taking this number substitute into either equation above
x+2(4)=13
x+8=13
x=5
Answer:
c - 7 < -18
Step-by-step explanation:
Seven subtracted from c : c - 7
c - 7 < -18
The probability of one head and one tail is 2/3.
<u>Step-by-step explanation</u>:
- The possibilities for flipping two fair coins are {T,T}, {H,H}, {H,T}, {T,H}
- Given the case that at least one coin lands on a head, So the total possibilities are {H,H}, {H,T}, {T,H} = 3 possibilities
- Required event is 1 head and 1 tail= {H,T}, {T,H} = 2 possibilities
To calculate the probability of one head and one tail,
Probability = required events / Total events
Probability = 2/3
Answer:
The answer is an isosceles triangle.
Answer:
Hope you got it....
Step-by-step explanation:
1=tan45∘
1=tan(22∘+23∘)
1=tan22∘+tan23∘1−tan22∘tan23∘
1−tan22∘tan23∘=tan22∘+tan23∘
1=tan22∘+tan23∘+tan22∘tan23∘
It will be the same for any two angles that add up to 45∘.
