Answer:
The sale price of the item is $
255
Step-by-step explanation:
To determine the amount of discount (
d
) offered by the store, we calculate
15
% of the sale price. Thus:
d = 300 × 15
÷ 100
d = 3
00 × 15 ÷ 1
00 (take the 2 zeros out on both the hundred and 3 hundred)
d = 3 × 15
d = 45
If the amount of discount is known, the sale price (
s
) of the item will be the regular price minus the discount. Hence:
s = 300 − 45
s = 255
Hope this helps you! If not sorry!
multiply all terms in the second equation by 2 to get the coefficient on the y variable to be -6.
Answer:
Step-by-step explanation:
0.25 x 0.044 = 0.011
a. Changing 0.25 to 25 moves the decimal 2 places to the right, and changing 0.044 to 44 moves the decimal 3 places to the right, so once we solve 25 x 44, we have to move the decimal a total of 5 places to the left.
25 x 44 = 1100, then move the decimal 5 places to the left to get 0.01100...but we don't add the zeros at the end.
b. multiplying 1/4 times 0.044 = 0.044/4 = 0.011
Hope this helps.
Answer:
x = 1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x−
5
5
=3
4x+−1=3
4x−1=3
Step 2: Add 1 to both sides.
4x−1+1=3+1
4x=4
Step 3: Divide both sides by 4.
