$100 * 0.2 = $20.
$100 - $20 = $80.
$80 * 0.1 = $8.
$80 + $8 = $88.
$88 * 0.2 = $17.60
$88 - $17.60 = $70.40.
Answer: $70.40

Can someone pls help me on 4 and 5
never [62]

Answer (4):

a=ub/k because

u=ak/b   (starting equation)

ub=ak    (multiply b to both sides)

a=ub/k   (divide both sides by k)

Answer (6)

x=g+c-y because

g=x-c+y  (starting equation)

x+y=g+c (add c to both sides)

x=g+c-y  (subtract y from both sides)

I dont understand how to do this inequality 4x +6 &lt;-6
Mama L [17]
4x + 6 < -6

First, subtract 6 from both sides. / Your problem should look like: 3x < -6 - 6
Second, simplify -6 - 6 to -12. / Your problem should look like: 3x < -12
Third, divide both sides by 4. / Your problem should look like: x < -\frac{12}{4}
Fourth, simplify \frac{12}{4} to 3. / Your problem should look like: x < -3

Answer: x < -3
