Answer:
Find below:
Step-by-step explanation:
To solve this, we either find the total cos5 of buying 40 bouquets at $2.50 or find the cost of one bouquet at $120.
Cost of one in pack of 40 at $120.
120 divided by 40 = $ 3
Now, we can see that $3>$2.50
This means that Kendra is wrong to buy the bouquet pack of 40 for $120
Hope this helps.
Good Luck

STEP
1
:
5a + 5b
Simplify ———————
a2 - b2
STEP
2
:
Pulling out like terms
2.1 Pull out like factors :
5a + 5b = 5 • (a + b)
Trying to factor as a Difference of Squares:
2.2 Factoring: a2 - b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (a + b) • (a - b)
Canceling Out :
2.3 Cancel out (a + b) which appears on both sides of the fraction line.
Final result :
5 / a -b

Answer:
a) 22 batches
c) 7.3 batches
Step-by-step explanation:
a) It takes 0.25 cup of sugar to make a batch of chocolate chip cookies. I have 5.50 cups of sugar. How many batches of cookies can I make?
0.25 cup = 1 batch
5.5 cup = x
Cross Multiply
0.25 cup × x = 5.5 cup × 1 batch
x = 5.5 cup × 1 batch/0.25 cup
x = 22
I can make 22 batches of chocolate chip cookies. You may use the scratchpad to show your work.
(b) Lemon Cookies It takes 0.75 cups of sugar to make a batch of lemon cookies. I have 5.5 cups of sugar. How many batches can I make?
0.75 cup = 1 batch
5.5 cup = x
Cross Multiply
0.75 cup × x = 5.5 cup × 1 batch
x = 5.5 cup × 1 batch/0.75 cup
x = 7.3 batches
I can make 7.3 batches of lemon cookies. You may use the scratchpad to show your work.
Answer:6 pieces can be cut and there will be no leftover wood
Step-by-step explanation:
Length of the wooden rod= 4 ft.
Length of the pieces of wood to be cut= 2/3 ft.
No. Of pieces can be cut = 4/ (2/3)
= 6 pieces
Hence the no. of pieces are not in decimal that indicates there is no leftover wood
