Initial charge charged by the Singer A = $50
Hourly charge of Singer A = $20
Initial amount charged by Singer B = $100
Hourly rate charged by Singer B = $10
Let us assume the time after which both singers will charge the smae amount of money = x
Then
50 + 20x = 100 + 10x
20x -10x = 100 - 50
10x = 50
x = 50/10
= 5
So after 5 hours both Singer A and Singer B will charge the same amount of money. I hope the procedure is clear to you and you can attempt such problems in future without needing any kind of help.
Answer:
X > - 2
Step-by-step explanation:
Subtract twelve from both sides
12( - 2x < 16
- 12. -12
-2x < 4
Divide both sides by -2 to undo the multiplicstion between -2 and x
-2x < 4
÷ -2 ÷ -2
<h2>
x > -2</h2>
(when you Divide both sides of an inequality by a negative number you switch the sign to the opposite)
Answer:
(a)
(b) 3, 4, 5
Step-by-step explanation:
(a) 4.5 × y = 9 and above
(b)
Possible y values = 2 and over
eg. 3, 4, 5
hope this helps :))
Okay so it’s pretty simple , basically it would be an arithmetic sequence if the constant number stays the same so in this case it would be
B - second one
E - fifth one
F sixth one
or it’d be the 2nd , 5th and 6th
