Answer:
To get the discount for the 5 pound bag of apples, we must first note the following:
The original price of the apples, which in this case it is 2.99
Also we must note the sale price for the apples which is 1.59
to get the discount for apples we must then create an equation based on the above information,
Discount for A= original price -sale price
Discount for A=2.99-1.59
Discount for A=1.40
Part 1 Answer is 1.40 which is the discount for apples at Handy Dandy Grocery.
Part 2
To get the discount for oranges we follow the same steps.
Discount for R= Original price for R -sale price for R
Discount for R=3.99-2.59
Discount for R=1.40
conclusion, for both part one and part two we can derive a formula based on the apples and orange and say discount in both cases is arrived by the following:
D=Op-Sp. ( d= discount, Or= original price, Sp= sale price.)

Answer:
b. 7x3 + 9x2 - 3x - 8
Step-by-step explanation:
Write the problem as a mathematical expression.
(4x3+6x2+2x−3)+(3x3+3x2−5x−5)
Remove parentheses.
4x3+6x2+2x−3+3x3+3x2−5x−5
Add 4x3
and 3x3
.
7x3+6x2+2x−3+3x2−5x−5
Add 6x2
and 3x2
.
7x3+9x2+2x−3−5x−5
Subtract 5x
from 2x
.
7x3+9x2−3x−3−5
Subtract 5
from −3
.
7x3+9x2−3x−8
Answer:
<h2>a. 40 + 20 + 3 + 6</h2>
Step-by-step explanation:
Points scored by Hessa is as shown below;
Round 1 = 43 points
Round 2 = 26 points
Total points for both rounds = 43 + 26 = 69 points
To determine the sum she could use to add the points together, we must select the sum that will give us the same total of points for both rounds i.e 69 points.
The Round 1 score (43 pt)can also be expressed as (40+3) points
The Round 2 score (26 pt)can also be expressed as (20+6) points
The sum she could use to add the points together will be (40+3)+(20+6)
which is also equal to 40 + 20 + 3 + 6 = 69points
Hence, option a is correct
