Answer:

x - y = 5

x + y = 23

x = 14, y = 9

Step-by-step explanation:

Make x subject:

x = 5 + y

Substitute c by (5 + y) :

( 5 + y) + y = 23

2y = 18

y = 9

Substitute y (9):

x = 5 + 9

x = 14

Sandra went for pizza with friends. She ordered a slice of pizza with a side salad for $9.50. The tax was 6.2%.
Anvisha [2.4K]

The total amount of money Sandra paid for a slice of pizza with a side salad including tax is $10.089

<h3>How to find total price including tax</h3>

  • Price of slice of pizza with a side salad = $9.50
  • Tax = 6.2%

Total amount Sandra paid = Price of slice of pizza with a side salad + (Tax × Price of slice of pizza with a side salad)

= 9.50 + (6.2% × 9.50)

= 9.50 + (0.062 × 9.50)

= 9.50 + 0.589

= $10.089

Therefore, the total amount Sandra paid is $10.089

Lilit [14]
Hi there!

The formula for the area of a triangle is A = 1/2(b x h). Using the information provided, all we have to do is plug in what we know and solve!

148 = b x 9.14
b = 16.2 inches (approximately)

Hope this helps!! :)
