Answer:
C
Step-by-step explanation:
3³ = 27
(3x²)³ = 27x⁶
(y³)³ = y⁹
(z³)³ = z⁹
ans = (27x⁶y⁹)/z⁹, which is answer C
Answer:
Option B. 1.8(2x + 7) – 15 = 3.6x – 2.4
Step-by-step explanation:
1.8(2x + 7) – 15
To know which option is correct, let us simplify the above expression. This can be obtained as follow:
1.8(2x + 7) – 15
Clear bracket
1.8(2x + 7) – 15 = 3.6x + 12.6 – 15
1.8(2x + 7) – 15 = 3.6x – 2.4
Thus,
1.8(2x + 7) – 15 is equivalent to
3.6x – 2.4
Answer:
z = 25
Step-by-step explanation:
7x + 2y = z
x = 3
y = 2
z = ?
First, let's put in the values we do know.
7(3) + 2(2) = z
Let's solve this.
7 * 3 = 21
2 * 2 = 4
21 + 4 = z
Now, we must add the two together to find z.
21 + 4 = 25
25 = z
z = 25
Well for that I got 6. Hope it helps :)
Abc= (2)(3)(4.91027)
=6*4.91027
=29.46162
