Solve for b if 7+16b=29+5b

Answers

Answer 1

Answer: 7 + 16b = 29 + 5b

Keep the variables on one side

16b - 5b = 29 - 7

11b = 22

Divide by 11 isolate b:

$(11b)/(11)$ = $(22)/(11)$
11 and 11 cancels out

b = 2

check:
7 + 16(2) = 29 + 5(2)
7 + 32 = 29 + 10
39 = 39

B.) 12
C.) 27
D.) 81

Answers

Hello from MrBillDoesMath!

Answer:

Choice D, 81

Discussion:

By log 3x = 4 I presume that "3" is the base not a multiplier of x. Assuming it is the base, then the equation is equivalent to

x = 3^4

= 81

This is Choice D.

Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 12 1 2 12 1 2 hours, on Tuesday he practiced for 2 14 1 4 14 1 4 hours, and on Wednesday he practiced for 1 12 1 2 12 1 2 hours. How many hours does Cesar need to practice during the rest of the week in order to have his 10 total hours?

Answers

Answer: See explanation

Step-by-step explanation:

Your question isn't really clear. Let me help you rephrase it and solve.

Let's say Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 1/2 hours, on Tuesday he practiced for 2 1/4 hours, and on Wednesday he practiced for 1 1/2 hours.

The total hours that Cesar has used in practicing will be:

= 1 1/2 + 2 1/4 + 1 1/2

= 5 1/4

To get the number of hours that Cesar need to practice during the rest of the week in order to have his 10 total hours, we subtract 5 1/4 hours from 10 hours. This will be:

= 10 - 5 1/4

= 4 3/4 hours.

Cesar needs to practice for 4 3/4 hours more.

Please help it’s with a graph thank you so much
