To find 10per cent just divide by 10, the answer is 8
Answer:
29,579 miles
Step-by-step explanation:
Divide Jupiter`s diameter by 3 which is 29,578.66 miles rounded up is 29,579 miles
Take 10% of the snowboard price.
10% = 0.1
109 * 0.1 = $10.90 (10% discount)
109 - 10.9 = $98.10 (Price with discount).
Take 12% of the new snowboard price.
12% = 0.12
98.1 * 0.12 = 11.772 (Round to 11.77)
98.10 - 11.77 = $86.33 (Final discounted price)
Take 6% tax on the new snowboard price.
6% = 0.06
86.33 * 0.06 = 5.1798 (Round to 5.18)
86.33 + 5.18 = $91.51

Answer:
1. 3x + 2
2. 0.25x - 6.5
3. $5.50 per sandwich
Step-by-step explanation:
1.
6x + 1 - (3x - 1)
PEMDAS says solve everything in the parentheses first
There is nothing left to simplify within the parentheses.
Since there's also no exponents, multiplication, or division, let's combine like terms starting from left to right
6x - 3x + 1 + 1
Negative + Negative = Positive, hence why it became 1 + 1
3x + 2
2.
(3x - 1) - 2.75 (x + 2)
PEMDAS says to do multiplication next (since parentheses are fully simplified and there are no exponents)
(3x - 1) - 2.75x - 5.5
Negative + Positive = Negative, hence why it became -5.5
3x - 1 - 2.75x - 5.5
Combine like terms
3x - 2.75x - 1 - 5.5
0.25x - 6.5
3.
Set up an equation:
Variable x = cost of sandwiches
4x + 4(2) = 30
4x + 8 = 30
Subtract 8 from both sides to isolate the variable
4x + 8 - 8 = 30 - 8
4x = 22
Divide both sides by 4
4x ÷ 4 = 22 ÷ 4
x = 5.5
$5.50 per sandwich
