Answer: I believe x = 105

Step-by-step explanation: When you add a triangles angles, you should get 180. The straight is equal to 180 degrees

Step 1: 180 - 55 - 50 = 75

Step 2: 180 - 75 = 105

Answer:

X=105

Step-by-step explanation:

Add angles

55+50 = 105

subtract from 180

180-105 = 75

it’s consecutive angles so subtract from 180

180-75 = 105

Step-by-step explanation:

Andrew found a pan of brownies with 3/4 of the brownies left. He ate 1/3 of what was left. What portion of the whole brownies did he eat?

The size of the brownies Andre ate =

1/3 of 3/4

= 1/3 × 3/4

= 1/4

Therefore, the portion of the whole brownies that Andre ate was 1/4

Step-by-step explanation:

We are given the following in the question:

Length of rectangle:

x\text{ feet}

Width of rectangle:

(x-7)\text{ feet}

Perimeter of rectangle:

2\times \text{(Length + Width)}

Expressions to calculate perimeter

1. ~2((x) + (x - 7))\text{ feet}\\2.~2(2x-7)\text{ feet}\\3.~ 4x-14\text{ feet}

The attached image shows the image of the rectangle.

5x + 2y = 2120

x + y = 574

2y = 2120 - 5x

2y = 1148 - 2x

1148 - 2x = 2120 - 5x

-972 = -3x

x = 324

574 - 324 = y

y = 250

Suppose f(x) = 5x - 4. Describe how the graph of g compares with the graph of f.
posledela

The graph of g(x) and f(x) are related by the given equation g(x) = f(x) + 12,

therefore, the ordered pair of the graph of g(x) is (f(x) + 12, x).

The choice that correctly describes how the graph of g(x) compares with f(x)

is the option; <u>H. The graph of g(x) is translated unit(s) up compared to graph </u>

<u>of f(x)</u>.

Reasons:

The given function is f(x) = 5·x - 4

The function g(x) = f(x) + 12

Required:

To select the correct choice from the given options

Solution:

The difference between f(x) and the required function, g(x), is the addition

of a constant positive value of 12 to the function f(x).

Therefore, each f(x) output value is further increased by 12 to obtain the

graph of g(x), which gives;

The graph of g(x) is translated 12 units up compared to the graph of f(x),

which corresponds with the option H.
