Answer:
x = 20
I am not sure if you wanted the answer. Sorry!
Step-by-step explanation:
Let's solve your equation step-by-step.
1/10 x + 5 = - 3x - 13 + 4x
Step 1: Simplify both sides of the equation.
1/10 x + 5 = - 3x - 13 + 4x
1/10 x + 5 = - 3x + - 13 + 4x
1/10 x + 5 = (<em>- 3x + 4x</em>) + (- 13)
1/10 x + 5 = <em>x</em> + - 13
1/10 x + 5 = x - 13
Step 2: Subtract x from both sides.
1/10 x + 5 - <em>x </em>= x - 13 - <em>x</em>
- 9/10 x + 5 = - 13
Step 3: Subtract 5 from both sides
- 9/10 x + 5 - <em>5</em> = - 13 - <em>5</em>
- 9/10 x = - 18
Step 4: Multiply both sides by 10/(- 9).
(<em>10/ - 9</em>) * (- 9/10 x) = (<em>01/ - 9</em>) * (- 18)
x = 20
Hope this helps!
Answer:
The total price of the groceries, including discount and tip is $110.4.
Step-by-step explanation:
Here, the bill amount of groceries = $120
Now, the coupon off = 20%
Calculating the discount, we get
20% of bill amount $120 = 20% of 120 = 
So, the 20% discount on the bill amount = $24
The actual payable amount = Bill Amount - Discount
= $120 - $24 = $96
Now, 15% tip is also applied on the actual payable amount $96.
15% of 96 = 
So, the total price t = Payable amount + Tip amount
= $96 + $14.4 = $110.4
or, t = $110.4
Hence, the total price of the groceries, including the discount and the tip is t = $110.4.
