Answer: Jamian bought 20 bagels and 15 donuts

Step-by-step explanation:

Using the equation below:

b + d = 35 ...... i

1.25b + 0.75d = 36.25 ....... ii

Multiply i by 1.25

Multiply ii by 1

1.25b + 1.25d = 43.75 ...... iii

1.25b + 0.75d = 36.25 ....... iv

Subtract iv from iii

0.50d = 7.50

d = 7.50 / 0.50

d = 15

Since b + d = 35

b = 35 - 15

b = 20

The answers are as follows.

a. 9x

In order to get this, you need to reevaluate 64 as a base of 4. Since 64 is equal to 4^3, we can rewrite the right side as

64^3x = (4^3)^3x = 4^9x

Which gives you the first answer.

b. 10

Similar to the first problem, we need to express 16 as a base of 2. 2^4 is equal to 16, so we use that in it's place and simplify.

16^5/2 = (2^4)^5/2 = 2^20/2 = 2^10

c. Sqrt(7.31)

This one is more simple. Raising something to a 1/2 power (.5) is the same as taking the square root.
