Answer:
x = 11.
Step-by-step explanation:
We have 2 lines crossing 3 parallel lines so:
5/6 = x-1 / 12
6(x-1) = 5*12
6x - 6 = 60
6x = 66
x = 11.
Answer: If the 40% off coupon is used, the subtotal will be $12.69
The gratuity would be exactly $4.23 (He will probably leave $4.25)
Step-by-step explanation: To find out the amount of the discount
.40 × 21.15 = 8.46
To find the new subtotal, subtract 12.15 - 8.46 = 12.69
To figure the tip: .20 × 21.15 = 4.23
Changing the percent to a decimal means divide the 20 by 100.
For this case, the first thing we should do is write the trinomial.
To do this, we add similar terms.
We have then:

Then, rewriting the trinomial we have:

Then, the trinomial is given by:

Factoring we have:

Rewriting we have:

Answer:
The trinomial factors are given by:

Answer:
20$
Step-by-step explanation:
Alyssa has 25$.
Allowance of her new shirt = 4/5 of her allowance on a new shirt .
The amount she spent on her new shirt is calculated as:
