Answer:
2.7
Step-by-step explanation:
0.5+1.2+1= 2.7
Answer:
A) 6
Step-by-step explanation:
-110= -2(8x+7)
Divide both sides by -2
55 = 8x+7
Subtract both sides by 7
48 = 8x
Divide both sides by 8
6 = x
The given equation is ⇒ 100 - (1/2) x = 92
100 - (1/2) x = 92 ⇒ Add (-100) to both sides
-100 + 100 - (1/2) x = 92 - 100
∴ -(1/2) x = -8 ⇒ Multiply both sides by (-2)
∴ -2 * (-1/2) x = -8 x -2
∴ x = 16
So, the value of x will be equal 16
Answer:
x = 0
Step-by-step explanation:
8x + 4 = 3(x − 1) + 7
Simplify both sides of the equation:
8x + 4 = (3)(x)+ (3)(−1) + 7
8x + 4 = 3x + (−3) +7
Combine like terms:
8x + 4 = (3x) + (−3+7)
8x + 4 = 3x + 4
Subtract 3x from both sides:
8x + 4 − 3x = 3x + 4 − 3x
5x + 4 = 4
Subtract 4 from both sides:
5x + 4 − 4 = 4 − 4
5x =0
Divide both sides by 5:
5x/5 = 0/5
<u>x = 0</u>
