The right answer is Option B and Option E.
Step-by-step explanation:
Given,
Price of french loaf =1f
Price of whole grain bread = 2f
Price of cinnamon rasin bread = 2f+2.50
Total amount spent = $11.25
According to given statement;
f+2f+(2f+2.50)=11.25

Subtracting 2.50 from both sides

f+2f+(2f+2.50)=11.25 and 5f=8.75 describes the situation.
The right answer is Option B and Option E.

Answer: They are equivalent, and x = -4/7
Step-by-step explanation:
Fist we need to see what the answers to each of these equations are
7 + 5x = 3 - 2x
Subtract 7 on each side
5x = -4 - 2x
Add 2x
7x = -4
X = -4/7
Now the second one
7 + 7x = 3
Subtract 7
7x = -4
X = - 4/7
They are equal and x = -4/7

Answer:
D) 0.35
Step-by-step explanation:
The table gives the area between z=0 and the given magnitude of z. That is, the area between z = 0 and z = -0.6 is 0.23, as found in the 0.6 column of the table. Similarly, the area between z = 0 and z = 0.3 is 0.12, as found in the 0.3 column of the table.
The area between z = -0.6 and z = +0.3 is the sum of these areas:
p(-.6<z<.3) = 0.23 +0.12 = 0.35
