D.-1
Step-by-step explanation:
as u have been told in the question that -2/2 the slash is division .
when you divide it gives you -1 as the answer .thank you
Answer:
4 cubes
Step-by-step explanation:
We can remove 6 cubes on each side and still make them balance. And we got 4 bags = 16 cubes, them we divide by 4 on each side, we can get 4 cube is in each bag.
3x+10=10
-10 -10
3x=0
If I remember correctly this is called “no real solution”
Answer:
•cos(s+t) = cos(s)cos(t) - sin(s)sin(t) = (-⅖).(-⅗) - (√21 /5).(⅘) = +6/25 - 4√21 /25 = (6-4√21)/25
•cos(s-t) = cos(s)cos(t) + sin(s)sin(t) = (-⅖).(-⅗) + (√21 /5).(⅘) = +6/25 + 4√21 /25 = (6+4√21)/25
cos(t) = ±√(1 - sin²(t)) → -√(1 - sin²(t)) = -√(1 - (⅘)²) = -⅗
sin(s) = ±√(1 - cos²(s)) → +√(1- cos²(s)) = +√(1 - (-⅖)²) = √21 /5
22) 2*16=32
32-6=26
23)15*1/5=3
24)45*1/5=9
25)7*2=14
14+8=22
26)1/5^2=1/25
1/25*50=2
