Answer:

48

Step-by-step explanation:

Given is an isosceles triangle:

[tex] \angle Y \cong \angle Z (isosceles \: \triangle \: theorem) \\

m\angle Z = m\angle Y=x\\

\therefore 84\degree + x\degree +x\degree = 180\degree \\

\therefore 84\degree + 2x\degree = 180\degree \\

\therefore 2x\degree = 180\degree - 84\degree \\

\therefore 2x\degree = 96\degree \\\\

\therefore x\degree = \frac{96\degree}{2} \\\\

\therefore x\degree = 48\degree \\

\therefore x = 48 \\

Answer:

g = 12b /5

Step-by-step explanation:

Given that:

Quarts of green paint = 4

Cup of black paint = 5/3

Quartz of green paint to be mixed with a given proportion of black paint.

Let proportion of black paint = b

Quartz of green paint = g

4 quartz = 5/3 cups

g quartz = b

Cross multiply :

4 * b = (5/3) * g

5/3 * g = 4b

g = 4b ÷ 5/3

g = 4b * 3/5

g = 12b /5

Slope = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Slope of a straight line passing two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph attached,

Line is passing through two points (20, 5) and (80, 20),

Therefore, slope of the line will be,

m = [tex]\frac{20-5}{80-20}[/tex]

m = [tex]\frac{1}{4}[/tex]

The slope is [tex]\frac{1}{4}[/tex].

18 tests

Step-by-step explanation:

Create a proportion where x is the number of tests after 9 weeks:

[tex]\frac{10}{5}[/tex] = [tex]\frac{x}{9}[/tex]

Cross multiply and solve for x:

5x = 90

x = 18

So, after 9 weeks, Vera will have taken 18 tests

Answer:

18

Step-by-step explanation:

18

10 tests     =   x tests

/ 5 weeks =   / 9 weeks

10* 9= x5

90/5=  18

Answer:

5x +12 =90

5x +12+ 90=180

90 + 5x +12 + x = 180

x + 90 = 5x +12

5x + 12 + x = 90

Answer:

y=2x-5

Step-by-step explanation:

Answer and explanation is in the picture.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation of the line that passes through the point (3, 1) and (1, -3) is

y = 2x - 5.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line is y = mx + c

(3, 1) = (a, b)

(1, -3) = (c, d)

Slope:

= (d - b) / (c - a)

= (-3 - 1) / (1 - 3)

= -4 / -2

= 2

m = 2

Now,

We can choose any point and set it as (x, y) and substitute it in the equation.

(3, 1) = (x, y)

y = mx + c

1 = 2 x 3 + c

1 = 6 + c

c = 1 - 6

c = -5

Now,

m = 2

c = -5

The equation of the line that passes through the point (3, 1) and (1, -3) is

y = 2x - 5.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

Base=3x-1

height =x

As we know that in a triangle

[tex]{\boxed{\sf Area={\dfrac {1}{2}}\times Base \times Height }}[/tex]

[tex]\qquad\quad {:}\longrightarrow\sf 22={\dfrac {1}{2}}(3x-1)(x)[/tex]

[tex]\qquad\quad {:}\longrightarrow\sf x (3x-1)=44 [/tex]

[tex]\qquad\quad {:}\longrightarrow\sf 3x^2-x=44 [/tex]

The equation that correctly shows the area of the triangle is 1/2x(3x - 1) = 22. Correct option is d.

To find the equation that correctly shows the area of the triangle, we use the formula for the area of a triangle:

Area = (1/2) * base * height

Given that the base is represented by 3x - 1 and the height is x, the area of the triangle is:

Area = (1/2) * (3x - 1) * x

Now, we are given that the area of the triangle is 22m^2:

(1/2) * (3x - 1) * x = 22

To solve for x, we can multiply both sides by 2 to eliminate the fraction:

2 * (1/2) * (3x - 1) * x = 2 * 22

x * (3x - 1) = 44

Now, we have the equation that correctly shows the area of the triangle:

x(3x - 1) = 44

So, the correct answer is:

x(3x - 1) = 44
