Answer:

Step-by-step explanation:

Total amount paid = 14,4000 + 8% of 14,4000

It is given that,

Kerry purchased a used car for 14,4000. And had to pay 8% sales tax

horsena [70]

Answer: Roses= 75, Sunflowers= 45

Step-by-step explanation:

Add the ratios- 5 + 3 = 8

Divide the total by the sum = 120 ÷ 8 = 15

Multiply the ratios- 5 x 15 = 75 and 5 x 3 = 45

∴ 5:3 = 75 , 45

Evaluate (y - 9) + (3 + x), when y = 15 and x = 5​
svet-max [94.6K]

Answer:

14

Step-by-step explanation:

It says 'Evaluate (y - 9) + (3 + x), when y = 15 and x = 5​'.

So we'd put 15 in y's place. It'll look like this (15 - 9).

Then we'd put 5 in x's place. It'll look like this (3 + 5).

You subtract (15 - 9) which equals 6. And you'd add (3 +5) which equals 8. You add 6 + 8 together since those are your answer for the parentheses. Your final should be 14. Hopefully this helped!
