$21.60 - $18.00 = $3.60

$3.60 : $18.00 = 0.2

0.2 · 100% = 20%

Is this right or not

mart [117]

The correct answer is x = 12

This is not correct. There are 180° in a triangle, not in each angle. To be 180°, the angle would need to be completely straight (not a triangle).

Since we know this is an equilateral triangle (all three sides are congruent to one another), it is also equiangular (all three angles are congruent to one another). There are 180° in a triangle -- which has 3 angles -- so divide that by 3 to get the measure of the angle (60°).

A farmer wants to plant peas and carrots on no more than 200 acres of his farm. If x represents the number of acres of peas and

AfilCa [17]

Answer:

Option D.(60, 135)

Step-by-step explanation:

Let

x -----> the number of acres of peas

y ----> the number of acres of carrots

we know that

The inequality that represent the problem is equal to

$x+y\leq 200$

so

<em>Verify each case</em>

case A) (-50,160)

substitute the value of x and the value of y in the inequality and then compare the result

$-50+160\leq 200$

$110\leq 200$ ----> is true

The point is a solution for the inequality, but is not a viable solution because the number of acres can not be a negative number

case B) (80,160)

substitute the value of x and the value of y in the inequality and then compare the result

$80+160\leq 200$

$240\leq 200$ ----> is not true

therefore

The point is not a solution

case C) (75,-200)

substitute the value of x and the value of y in the inequality and then compare the result

$75-200\leq 200$

$-125\leq 200$ ----> is true

The point is a solution for the inequality, but is not a viable solution because the number of acres can not be a negative number

case D) (60,135)

substitute the value of x and the value of y in the inequality and then compare the result

$60+135\leq 200$

$195\leq 200$ ----> is true

therefore

The point is a viable solution

Kathleen bought 4 dresses that each cost the same amount and pair of jeans that cost $40. The items she bought cost a total of $

stepan [7]

Each dress would be $30 because, if you do 160-40 = 120 then 120 divided by 4 = 30. So that’s the answer 30

barxatty [35]

Answer:

524.96 − 32.50 + x ≥ 500

Amount need to deposit = $7.54

Step-by-step explanation:

Given:

Amount in checking account = $524.96

Maintain amount = $500

Amount of check = $32.50

Find:

Amount need to deposit

Computation:

Assume, amount need to deposit = x

So,

For avoiding fee

524.96 − 32.50 + x ≥ 500

x = 7.54

Amount need to deposit = $7.54
