If 5 in and 8 in are legs:
hypotenuse = √(5²+8²) = √89 ≈ 9.4 in.
If 5 in is the leg and 8 in is the hypotenuse:
other leg = √(8²-5²) = √39 ≈ 6.2 in.
<span>The difference between the two possible lengths of the third side =
9.4 - 6.2 = 3.2 in.</span>
Step-by-step explanation:
30*16/100;
3*16/10 = 4,8 pounds.
8x + 14y = 4
-6x - 7y=-10 / *2
8x + 14y=4
-12x -14y= -20
_________________
-4x=-16 => x=4; y= -2
Answer:
3
Step-by-step explanation:
Simply plug the number after the semi colon into each question's respective variable.
1. Is k=-1 a solution to this problem?
Is 9(-1)=10-(-1)?
we see that -9=10+1=11 which is not a true equality. since -9 is not 11 then "No" is the correct answer to number 1.
3.
3(-10)÷(-6)=5-(-10) ?
-30÷-6=5+10?
5=15?
No, not true, thus "No" is the correct answer.
5. 8-8=2(8)-16?
Is 0=16-16 ?
Yes!
7.
Is 2(7-2)-5(7)=5(2-7)?
2(5)-35=5(-5)?
10-35=-25
-25=-25
Bingo! Yes.
