Answer:
B) -1-6 x +15 = x - 15 +15
Step-by-step explanation:
<u>Explanation</u>:-
Given equation is –1 – 6 x = x – 15
<em>By addition property of equality </em>
<em> ⇒ - 1 - 6 x + 15 = x - 15 +15</em>
⇒ - 6 x + 14 = x
subtracting 'x' on both sides ,we get
⇒ - 6 x -x +14 =0
⇒ - 7 x +14 =0
⇒ -7 x = - 14
Dividing '-7' on both sides , we get
x = 2
<em>The solution of given equation is x = 2</em>
Answer:
$15 1/10
Step-by-step explanation:
Given that :
Total amount to spend = $30
Amount spent on Gift A = $9 1/4
Amount spent on Gift B = $5 4/5
Amount left to spend on gift C ;
$30 - (9 1/4 + 5 4/5)
$30 - (37/4 + 29/5)
$30 - (185 + 116)/20
$30 - 298/20
30/1 - 298/20
$(600 - 298) / 20
$302/20
$15 2/20
= $15 1/10
