for delivering newspapers. at the end of
20
weeks, she stopped mowing lawns and delivering newspapers and spent
$300

. she didn't earn or spend any money besides what is described here.
write a numerical expression with parentheses for the amount of money kathy has left.
do not simplify your expression.

The expression is :

Step-by-step explanation:

Every week for 20  weeks, Kathy earned $15  for mowing lawns and $35 for delivering newspapers.

In 20 weeks, the earnings from mowing lawns will be =

In 20 weeks, the earnings from delivering newspaper will be =

At the end of 20 weeks she spent $300 and was left with :

dollars

Or can be written as : dollars

This is the expression to solve the problem.

answer:

c. the third graph

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
