Hi, I have a question.

Choose a value for a that is greater than 5 and less than 15. Evaluate the perimeter of the pen for that value, using one of the expressions that you wrote. My expression: 2a +2b

Jacqueline has two part-time jobs. She earns $15 per hour, l , working as a lab assistant, and $12 per hour, s , working as a cashier. This is modeled by 15l+12s . Evaluate for l=5 and s=7 to find how much money Jacqueline will earn at her two jobs this w...

hello can you help me answer one more question on my math test?

Oh, it's AI! A county planner prepares the following table showing population trends in three local towns. The first column gives the name of the town. The second column gives the population as of the last census. The third column gives the estimated incr...

Thank you AI! Add a fourth row to the table showing the population information for the town of Concord. Concord’s population as of the last census was p people; for its percentage change, choose a negative integer not divisible by two. Write two expressio...

Are there any other easier expressions you could use?

Choose a number greater than 5,000 and less than 10,000 for the value of p. Based on the percentage change you chose in part b, calculate the estimated current population of Concord, rounding to the nearest whole number if needed. Explain why you used the...

A’Leila is building a pen for her pet donkey. The pen is a rectangle with one side measuring b yards and the adjacent side measuring a yards. A’Leila knows that a = 1/3b . a. Write two different expressions giving the perimeter of the donkey’s pen.

. Explain why you used that expression to evaluate the perimeter of the donkey’s pen.

And you're completely sure????? if you are, next question: simplify: 5a - 8c + b + 3c - 9a + 6b

Is that correct. I'm double checking my answers btw, and I didn't get that. Maybe I did it wrong, but you need to double check

Idk if you're correct so I'm checking other sources. I'll see if you are, robot

simplify 3/4r + 3 - 5/6r - 6

Ok thanks! what is the expression 4+8(3x-2)-7x when simplified? Apply the order of operations and the commutative and distributive properties. Show your work.

can you make that little bit easier, with more explanation, from a 7th grader's point of view??
