The second description is not suitable.
It should be "simplify the terms" sice you are just adding 36 and -20.
Consider the given expression,
Apply the distributive property,
Combine like terms,
Subtract 20 from both sides,
Divide both sides by 27,
Answer:
30kg
Step-by-step explanation:
5 x 6=30
The number terms in the given expression is 3, they are 5xy, -3x and -82.
The given expression is 5xy-3x-82.
<h3>What is an expression?</h3>
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.
Variable: A variable is a symbol that doesn't have a fixed value.
In the given expression 5xy-3x-82, there are three terms, which are 5xy, -3x and -82.
Therefore, the number terms in the given expression is 3, they are 5xy, -3x and -82.

Answer:
Step-by-step explanation:
Let x represent the amount of medical bills that Giselle has to pay.
Assume she has over $160 in bills,
it means that
x > 160
Under plan A, Giselle would have to pay the first $110 of her medical bills, plus 35% of the rest. Therefore, she will have to pay for
35/100 × (x - 110) = 0.35(x - 110)
Under plan B, Giselle would pay the first $160, but only 20% of the rest. Therefore, she will have to pay for
20/100 × (x - 160) = 0.2(x - 160)
Therefore, the amount of medical bills that plan B will save is
0.35(x - 110) - 0.2(x - 160) = 0.35x - 38.5 - 0.2x + 32
0.15x + 6.5
Substituting x = 160 into 0.15x + 6.5, it becomes
0.15 × 160 + 6.5 = $30.5
Total bills would be 160 + 30.5 = 190.5
Therefore, Giselle would save $30.5 with plan B if she had more than $190.5 in bills.
