Answer:
34
Step-by-step explanation:
42/21 = x/17
solve to get the answer
2 = x/17
2*17 = x/17 * 17
34 = x
$44.80=($35+X)(1-0.3)
44.80 is the final total
You need to add the glove and hat cost to get a subtotal (35+x) and then multiply by what is left after the discount 30% off will leave 70% to pay, so in this equation 1-0.3 leaves 0.7 to multiply against the subtotal to get the total before tax of 44.80
The answer is 10mph because you divide 30 by 3hours. I hope this helps. Could I possibly get brainliest?
Answer:
10.
Step-by-step explanation:
I am assuming that z is a whole number.
160z = x^2
z = x^2/ 160.
160 = 2*2*2*2*2*5
To make this a perfect square we multiply by 2 * 5
- this gives us 1600.
z = 1600/160 = 10.
