Jim gets a $20 allowance per week plus $25 for every lawn he mows. if he made $345 in one week, how many lawns did he mow?

This is a 2-step equation...

$25 per week per lawn. (the number of lawns could vary so that will be our variable "x".)

and he gets $20 allowance... this does not change so we will call it a constant

This week the number of lawns "times" 25 and his allowance = $345

Therefore...

25x + 20 = 345

- 20 -20

25x = 325

Now divide both sides by the coefficient (25)... and that will be the number of lawns he mowed.

Alright. Let's break this down.

25 x 13 = 325

325 + 20 = 345

So that means Jim mowed 13 lawns. ;) Hoped this helped?

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
