Answer:

D is the answer

Step-by-step explanation:

Answer:

11/12

Step-by-step explanation:

Given the expression 1/3 + a = 5/4

Subtract 1/3 from both sides

1/3 + a - 1/3 = 5/4 - 1/3

a = 5/4 - 1/3

a = 15-4/12

a = 11/12

Hence the value of x is 11/12

Answer:51.5 degree

Step-by-step explanation: Since DEF is an isosceles triangle, angle D and F needs to be equal. So substract 77 from 180 and divide by 2.

Answer:

Step-by-step explanation:

let angle D and angle F be x

x+x+77=180 degree(being sum of the interior angle of a triangle)

2x=180-77

x=103/2

x=51.2 degree

both angle D and F are 51.2 degree because the base angles of an isosceles triangle are equal.

Answer:

300in²

Step-by-step explanation:

l= 12

w= 9

h= 2

Substitute into the equation

S= 2(lw+ wh + hl)

S= 2( 12x9 + 9x2+ 12x2)

S= 2( 108+ 18 + 24)

S= 2( 150)

S= 300

Answer:

y = -x + 3

Step-by-step explanation:

Given:

Coordinates are (2, 1) and (6, -3)

y = mx + c

For Coordinate (2, 1)

1 = m(2) + c

1 = 2m + c ........... Eq1

For Coordinate (6, -3)

-3 = m(6) + c

-3 = 6m + c ........... Eq2

From Eq2 - Eq1

6m - 2m = -3 - 1

4m = - 4

m = -1

From eq 1

1 = 2m + c

1 = 2(-1) + c

1 = -2 + c

c = 2 + 1

c = 3

So,

y = mx + c

y = (-1)(x) + 3

y = -x + 3

Answer:

The second option is correct.

Step-by-step explanation:

This is because when multiplied, they all equal the same number.

Answer:

y = 23

Step-by-step explanation:

The angle vertically opposite 3y is congruent, then

(5y - 4) and 3y are same- side interior angles and sum to 180°, that is

5y - 4 + 3y = 180

8y - 4 = 180 ( add 4 to both sides )

8y = 184 ( divide both sides by 8 )

y = 23

Answer: add 4 to both sides

Step-by-step explanation:

Answer:

the answer is add 4 to both sides

Answer:

= 11/2

Step-by-step explanation:

When we have two points, we can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( -4 -7)/(-6 - -4)

    = ( -4 -7)/(-6 +4)

    = -11/-2

     = 11/2

Answer:

O ion

Step-by-step explanation:

Well, when electrons are added or subtracted from an atom, there is a change and it becomes an ion.

Answer:

an atom is a small particle they can take part time n chemical reaction

Answer:

rate of change=5

Step-by-step explanation:

Hi there!

The rate of change (or the slope) is calculated from two points with the formula (y2-y1)/(x2-x1)

we are given two points: (1,-1), and (2,4)

let's label the points, to avoid confusion:

x1=1

y1=-1

x2=2

y2=4

now substitute into the formula:

*note: remember that we are subtracting the negative numbers. When it's simplified, we add the numbers.

rate of change=(4--1)/(2-1)

simplify:

rate of change=(4+1)/(2-1)

rate of change=5/1

rate of change=5

Answer: Number of students tickets were sold = 120

Number of adults tickets were sold = 200

Step-by-step explanation:

Let x= Number of adults, y = Number of students

As per given,

x+y=320    ...(i)

4x+2.5y=1100 ...(ii)

Multiply 2.5 on both the sides of (i), we get

2.5x+2.5y=800   ...(iii)

Subtract (iii) from (ii), we get

1.5x=300

[tex]x=\frac{300}{1.5}\\x=200[/tex]

From (i) y= 320-200 = 120

Hence, Number of students tickets were sold = 120

Number of adults tickets were sold = 200
