Answer:
(64,86.5)
Step-by-step explanation:
find the case where he gets 70 and the case where he gets 79
if his average is 70:
(75+62+85+2x)/5=70
(222+2x)/5=70
222+2x=350
2x=128
x=64
if his average is 79:
(75+62+85+2x)/5=79
(222+2x)/5=79
222+2x=395
222+2x=395
2x=173
x=86.5
Answer:
Kate = 52 seconds, Alexia = 58 seconds, Trina = 49 seconds
Step-by-step explanation:
A = K + 6
T = K - 3
K + A + T = 2 min 39 sec or 159 sec
K + (K + 6) + (K - 3) = 159sec
3K + 3 = 159sec
3K = 156sec
K = 52 sec
A = 52 + 6 = 58 sec
T = 52 - 3 = 49 sec
Answer:
Step-by-step explanation:
Using the problem statement as the basis for the equation, we can write ...
h -102 = 331
__
Using the diagram as the basis for the equation, we could write it as ...
h = 331 +102
__
The original height of the helicopter was 433 m.
1.5, 2.25, 3.375, 5.0625, 7.59375... and so on
97.45 • 0.18 = 17.54. 97.45 + 17.54 = 114.99. I think this is right.
