Answer:

348.

Step-by-step explanation:

Answer:

C) Both (1 , 11) and (-1, -5)

Step-by-step explanation:

y = 8x + 3

Plugin x = 1  and y = 11 in the equation

11 = 8*1 + 3

11 = 8 +3

11 = 11

So, (1 , 11)  is a solution.

Plugin x = -1  and y =-5 ,

-5 = 8*(-1) + 3

-5 = -8 + 3

-5 = -5

So, (-1 , -5) is also a solution

Answer:

y=14.5

Step-by-step explanation:

A slope of 3/2 means that for every unit it moves to the right, it will move 1.5 units up. The x of 4 is 7 more than the -3 of our other point. 7*1.5=12.5, and 12.5+2=14.5.

Answer:

x=0.0278 or 1/36

Step-by-step explanation:

y=4

So,y=1/9x

4=1/9x

36x=1

x=1/36

x=0.0278

Answer:

The Third number is 19

Step-by-step explanation:

7 + 2 = 11 then add 19=

11 + 19 = 30 After divide by three because there are 3 numbers

30.6 ÷ 3 = 10

Remember: To find the mean you add all the numbers together and divide by how many numbers are there.

For example: you have 2, 5, 8 you add them together which is 15. There are 3 numbers so you divide 15 by 3 which is 5.

The value of 'n' is approximately 4.0896.

To calculate the value of 'n' in the equation 134n = 548, we can isolate 'n' by dividing both sides of the equation by 134.

134n = 548

Dividing both sides by 134:

n = 548 / 134

Evaluating the division:

n ≈ 4.0896

Therefore, the value of 'n' is approximately 4.0896.

Answer:

372.r2

Step-by-step explanation:

Answer:

x=21, y= 35

Step-by-step explanation:

3x+7=5x-35

(subtract seven from -35)

3x=5x-42

(subtract 5 from 3)

-2x=-42

(-42/-2= positive number)

x=21

y+75=3y+5

(subtract 75 from 5)

y=3y-70

(subtract 3y from y)

-2y=-70

y=35

Answer:

132.50

Step-by-step explanation:

3/5b = 79.50

b = (79.50) / (3/5)

b = 79.50 * 5/3

b = 397.50/3

b = 132.50

132.50 is the total bill

6 is a solution

Answer:

My best answer is A

Step-by-step explanation:

if you plug in 6 for r, it doesn't work for A.

B is hard to see so can't tell

C works with r=6, so it's not C

and D works as well, so it's not D

Answer:

-4+7, -4 - (-7)

Step-by-step explanation:

The given expression can be simplified:

-(4+(-7)) = -(4-7) = -(-3) = 3

The equivalent choices will all equal 3. Testing each choice:

-4+7 = 3

-4+(-7) = -4-7 = -11

4+(-7) = 4 - 7 = -3

-4 - (-7) = -4 + 7 = 3

Only the first and last choice are equivalent to the original expression.

Answer:

H(-3)= -0.5

H(0)= 7

H(1)= 9.5

Step-by-step explanation:

For H(-3)

Substitute all of the x into -3

H(-3)=2.5(-3)+7

2.5 times -3 is -7.5

-7.5+7 is -0.5

So the answer for H(-3) is -0.3

For H(0)

Substitute all of the x into 0

H(0)=2.5(0)+7

2.5 times 0 is 0

0+7 is 7

So the answer for H(0) is 7

For H(1)

Substitute all of the x into 1

2.5(1)+7

2.5 times 1 is 2.5

2.5+7 is 9.5

So the answer for H(1) is 9.5

Answer:

x = 36.9°

Step-by-step explanation:

We need to find out what sides of the triangle we have, so we can find the formula for the missing angle, x.

We have been given the opposite and hypotenuse so we are using sine

SOH, CAH, TOA

sin (x) = opp ÷ hyp

Substitute in the values

sin (x) = 9 ÷ 15

Simplify

sin (x) = 0.6

Rearrange to find x

x = sin^-1(0.6) - Type this into your calculator

x = 36.8698... ≈ 36.9°

Witch hat = 5

Jack o' lantern = 2

Ghost = 7

Witch Pot = 10

7 x 5 = 35 + 5 = 40

10 x 2 = 20 + 2 = 22

7 + 10 = 17 + 10 = 27

2 x 5 = 10 + 7 = 17

7 + 7 = 14 + 5 = 19

1. 7x5+5=40

2. 10x2+2=22

3. 7+10+10=27

4. 2x5+7=17

5. 7+7+5=19
