Markia saved for a new bike. The bike was on sale for a discount of 35%. The original cost of the bike was $270. How much did sh
masya89 [10]
35% would be the same as .35
So multiply 270 by .35 and you woild get $94.50

Then you take 270 and subtract it by 94.50 and you get 175.50.

So your answer would be $175.50.

Hope this helps!

Answer:

<u>The correct answer is 58 1/2 feet. See below to understand the difference of both methods.</u>

Step-by-step explanation:

1. Let's review the information provided to us for solving the question using both methods:

Area of each student = 4 1/2 square feet

Number of students = 13

2. Let's use the first method to solve the question:

4 1/2 = 9/2 (Improper fraction because the numerator, 9 is bigger than the denominator, 2)

9/2 * 13 = 117/2

<u>117/2 = 58 1/2 square feet</u>

3. Let's use the second method to solve the question:

4 1/2 = 4 + 1/2 (Using addition to rewrite the fraction)

(4 + 1/2) * 13 = (4 * 13) + (1/2 * 13) (Distributive property of the multiplication)

(4 * 13) + (1/2 * 13) = 52 + 13/2 = 52 + 6 1/2

<u>52 + 6 1/2 = 58 1/2 square feet</u>

Use the quadratic formula to solve the equation. -2x^2-x+7=0.
Furkat [3]
<span>-2x^2-x+7=0  
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c

using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))

(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify 

(1±√(1+56))/4

1±√(57)/4 is your answer
