Answer:
x = -1
Step-by-step explanation:
8x = - 4(x + 3)
8x = -4x - 12
+4x +4x
<u>12x = -12</u>
12 12
x = -1
- Remember, a negative times a positive equals a negative
- Remember, a negative divided by a positive equals a negative
Hope this helps you!!! :)
Answer:
a = 3, b = -1, c = 10
Step-by-step explanation:
Let the three numbers be a, b and c.
Equation 1: a + b + c = 12
Equation 2: a + 2b + 3c = 31
Equation 3: 9b + c = 1
Equation 2 - Equation 1:
Equation 4: b + 2c = 19
Equation 3 times by the number 2
Equation 5: 18b + 2c = 2
Equation 5 - Equation 4
17b = -17
b = -1
Substitute into Equation 4:
2c - 1 = 19
2c = 20
c = 10
Substitute into Equation 1:
a + b + c = 12
a - 1 + 10 = 12
a = 3
Answer:
a=0.1
Step-by-step explanation:
From the given frequency table, Fiction= Poetry+Prose=total
⇒0.2+0.8=1.0=total
And, Poetry+prose= total
⇒0.18+0.82=1.0= total
Thus, following the same path,we have
Non Fiction= Poetry+prose=Total
⇒a+0.9=1.0
⇒a=1.0-0.9
⇒a=0.1
Therefore, the value of a will be: 0.1
