Could I see a picture cause not sure
Answer:
-8
Step-by-step explanation:
Let Peter's hit be x and Alice's runs be y.
x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)
Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8
Therefore, Peter hit 8 home runs and Alice hit 10 home runs.
Answer:
1/5 lawn = 20 min.
? = 1 min
0.05 lawn in 1 minute
rate of 0.05 mowed per minute.
Let us take each number as x = 2x , 3x, 4x
(2x)³+(3x)³+(4x)³=12375
8x³+27x³+64x³=12375
99x³=12375
x³=12375/99
=125
x =∛125
x=5
2x=2×5=10
3x=3×5=15
4x=4×5=20
therefore, the three numbers are 10,15 and 20 .....
Hope it helps !!
