Answer:
2.5, 6 and 6.5 inches.
Step-by-step explanation:
5 + 12 + 13 = 30
So the shortest side = 5/30 * 15 = 1/6 * 15
= 2.5 inches.
The longest = 13 / 30 * 15 = 13/2
= 6.5 inches,
and the third = 12/30 * 15
= 6 inches.
Answer:
a=-6
Step-by-step explanation:
4= 6/a + 5
Subtract 5 from each side
4-5= 6/a + 5 -5
-1 = 6/a
Multiply by a on each side
-1*a = 6/a *a
-a =6
Multiply by -1
a= -6
We know that Bob and Caitlyn are playing a trading-card game. Between them, they have 81 cards. <span>Bob has 7 fewer cards than Caitlyn. Since Bob has 7 cards fewer them Caitlyn we have to divide by 2 and subtract 7.
81 / 2 = 40 [rounded]
40 - 7 = cards Bob has
= 33 cards bob has
</span>
