1/4 = 16/t.....1 elephant to 4 tigers = 16 elephants to t tigers
cross multiply
(1)(t) = (16)(4)
t = 64 <=== 64 tigers
Answer: x = 1, y = -2
Step-by-step explanation:
-9x+2y=-13
x= 13/9 + 2/9y
2x-9y=20
2(13/9+2/9y)-9y=20
<em>Substitute y with -2.</em>
<em />
x= 13/9+2/9(-2)
<em>After solving you'll see that 1 is a possible solution for x.</em>
<em />
Check your answer
-9x+2y=-13
-9x1+2(-2) = -13
2x-9y=20
2x1-9(-2) = 20
-13 = -13
20 = 20
Therefore, x=1 and y=-2
The final temperature is the sum of the initial temperature and the change in temperature. The initial temperature is 102°F. The change in temperature is -3°F.
Operation:
Tf = Ti + ΔT = 102°F + (-3°F) = (102 - 3)°F = 99°F
There are 5 + 7 = 12 triangles or hexagons. So the probability is 12/15 = 4/5. As a percent, it would be 80%.
