Answer:
the answer is 30
Step-by-step explanation:
Let the number be x
- 3 (x - 12) = - 54
-3x + 36 = -54
-3x = -54 - 36
-3x = -90
x = -90/-3
x = 30
Answer:
The correct answer is 5.8
Step-by-step explanation:
Janae did not read the minus/negative sign correctly. She subtracted instead of added, meaning she did not isolate her c.
3.67=c-2.13
+2.13 +2.13
5.8=c
Complete Question
Apabila a =2 b = 3 dan c =12 tentukan nilai dari bentuk :
a⁶× b⁴ × c²
(ab)² ×c³
Answer:
1) a⁶× b⁴ × c² = 746496
2) (ab)² ×c³ = 62208
Step-by-step explanation:
a =2, b = 3, c =12
a) a⁶× b⁴ × c²
2⁶× 3⁴ × 12²
= (2 × 2 × 2 × 2 × 2 × 2) × (3 × 3 × 3 × 3) × (12 × 12)
= 64 × 81 × 144
= 746496
b) (ab)² ×c³
(2 × 3)² × 12³
= 6² × 12³
= (6 × 6 )× (12 × 12 × 12)
= 36 × 1728
= 62208
Answer:
x - 3y + z
Step-by-step explanation:
Terms are just names for objects inside the equation -- anything that isn't an operation. A coefficient the is the number a given term (variable) is being mulitpled by. In this case, -3 for y, and 1 for. x. We can deduce from this the start of the expression (x has no coeff. bc of multiplicative identity)
x - 3y
We know we are missing one term, and we also know that the third term cannot be constant, so it must be another variable. In this case I have chosen Z, in theory it shouldn't really matter but z is the best variable name in this case.
If 7 out of 10 candles are lit, then seven-tenths of the candles are lit. The tenths place is directly to the right of the decimal. Since you have seven-tenths, the tenths place will be seven. So, the decimal that represents the candles lit will be 0.7
