Parallelogram Property: opposite angles are congruent Solve for x

Mathematics
1 answer:
Anna11 [10]3 years ago
5 0

Answer:

Step-by-step explanation:

Equate the two opposite Angles

7x - 31 = 5x + 13                Subtract 5x from both sides

7x - 5x - 31 = 13                 Combine

2x - 31 = 13                        Add 31 to both sides

2x = 13 + 31                       Combine the right

2x = 44                             Divide by 2

x = 44/2

x = 22

· Amanda has $210 in her school lunch account. She spends $35 each week on school lunches. The
tigry1 [53]

Answer:

(See step-by-step)

Step-by-step explanation:

Let’s start by making A-(X) and W-(Y). So, when substituting the variables you get x=210-35y. When x=0, the answer to the equation is 6. So, the y-intercept (when x=0) is 6 or (0,6). When y=0, the answer to the equation/x-intercept(y=0) is 210 or (210,0). The graph itself looks like the image included.

The domain, realistically, is x>=0 however on the graph itself, the domain is x= All Real Numbers. The range realistically is y>=0, but on the graph it is also All Real Numbers.  

The x-intercept is the account when no weeks have passed and no money is lost (210) and the y-intercept is the maximum amount of weeks before there is no more money in the account (6).

Tom decides to paint one wall in his room green. Use the dimensions below to calculate the area of the this wall.
Anton [14]

Option C:

Area of the wall =94\frac{15}{16} square feet

Solution:

Length of the wall = 12 \frac{1}{4} feet

Width of the wall = 7 \frac{3}{4} feet

Area of the wall = length × width

                          $=12 \frac{1}{4}\times 7 \frac{3}{4}  

Convert mixed fraction into improper fraction.

                          $=\frac{12 \times 4+1}{4}\times  \frac{7\times 4+3}{4}

                          $=\frac{49}{4}\times  \frac{31}{4}

                          $=\frac{1519}{16}

Convert improper fraction into mixed fraction.

                          $=94\frac{15}{16}

Area of the wall =94\frac{15}{16} square feet

Option C is the correct answer.

To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
aliina [53]
1) change 65% to a decimal = .65

2) .65 • 60 = 37.2 questions need to be right

3) since she got 42 correct, that is greater than 37.2, so she passed.

OR

1) 42/60 = 0.7

2) 0.7 to a percent = 70%

3) since she got a 70% on the test, she passed.
