combine the terms 9(5-3a) + 12a -23?

Question

I am needing some desperate help wih my 7th grade math homework

Answer 1

1. 9(5-3a)+12a-23
2.distribute 9 by 5 and then by negative three
3, then subtract 23 from the number you get from(9*5)
4, and add 12 to the number you get from(9*(-3))
5. that is your answer or the best help i could give you without telling you the answer directly

Answer 2

For the first part you would distribute the 9 by multiplying both the 5 and the 3a by the 9. You would then combine like terms (the ones with an a after it and the ones without an a) , by adding or subtracting.

Answer 3

first you need to distribute the 9 with multiplication. you get (9x5) - (9 x 3a) + 12a - 23 which equals 45 - 27a + 12a - 23. combining like terms gives you (45 - 23) + (-27a + 12a) = 22 - 15a

Answer 4

9(5-3a) + 12a -23

Step 1 Distribute 9(5-3a) by doing 9x5 & 9x-3a

45-27a + 12a -23

Step 2 Add like terms

-27a+12a+45-23
-15a+22

Answer 5

Distribute first the 9
45-27a+12a-23
then, combine the like terms
22-15a is the solution--- -15A+22 another way to show it.

Answer 6

40 -27a +12a -23 would equal 17-15a

Answer 7

distribute
45-27a + 12a - 23

45-23 since 23 is ngative
-27a + 12a=
22 - 15a

Answer 8
