Teresa counted 2 leaves on May 1st and 9 leaves on September 1st.
The difference in the number of leaves is:
9 - 2 = 7
Hence, the number of leaves has increased by 7 units.
Determined by the signs multiplication is × or using it or could be 2 numbers attached like this 2y but for deciding it's a ÷ or / but that is some of the signs
2x - y = -2 . . . (1)
5x - 2y = -7 . . . (2)
From (1), y = 2x + 2 . . . (3)
Putting (3) into (2), gives:
5x - 2(2x + 2) = -7
5x - 4x - 4 = -7
x - 4 = -7
x = -7 + 4 = -3
y = 2(-3) + 2 = -6 + 2 = -4.
Therefore, the required answer is (-3, -4)
Answer:
<u>16.75 cu. in.</u>
Step-by-step explanation:
Volume = 1/3πr²h
= 1/3 x 3.14 x 4 x 4
= 50.24 / 3
= <u>16.75 cu. in.</u>
The answer will be x = 8.
I hope this helps you! :)
