Answer:
3/10
Step-by-step explanation:
You have to make them the same fraction.
2/5 = 4/10
3/10 =3/10
3/10 + 4/10 = 7/10
10/10 - 10/10 =3/10
3/10 is the amount of tigers.
Answer:
20
Step-by-step explanation:
1/2(a+b)=180
1/2(6+12)=18
1/2(18)=180
9/9=180/9
=20
Wouldn’t it be (-2+12)/2 which is 10/2 which is 5. Because that’s how the midpoint formula works you find starting point and end point, you add those two up together and then divide by 2. So the answer for this one is 5.
(y -3)^2 = 4y - 12
Expand.
(y-3)(y -3) = 4y - 12
y² - 6y + 9 = 4y - 12
y² - 6y -4y + 9 + 12 = 0
y² - 10y + 21 = 0
Factors are -7y and - 3y
y² - 10y + 21 = 0
y² - 3y - 7y + 21 = 0
y(y - 3) -7(y - 3) = 0
(y - 3)(y - 7) = 0
y-3 = 0 or y - 7 = 0
y = 0 + 3 or y = 0 + 7
y = 3 or 7
