Step-by-step explanation:

7.80=66(.05)+.10(x)

7.80=3.30+.10(x)

7.80=3.30+.10x

4.50=.10x

x=45

Check

66 nickels at .05=3.30

45 dimes at .10= 4.50

3.30+4.50= 7.80

Answer:

a. 9 sides

b. 18 sides

c. 24 sides

d. 30 sides

Step-by-step explanation:

We can use the equation 180(n-2), which n is the number of sides to find the answer.

a. 180(n-2)=1260

n-2=7

n=9

b. 180(n-2)=2880

n-2=16

n=18

c. 180(n-2)=3960

n-2=22

n=24

d. 180(n-2)=5040

n-2=28

n=30

Answer:

a) 9 sides

b) 18 sides

c) 24 sides

d) 30 sides

Step-by-step explanation:

sum of interior angles = (n - 2) * 180

where n is the number of sides

a) 1260

(n - 2) * 180 = 1260

(n - 2) = 1260/180

(n - 2) = 7

n = 7 + 2

n =  9

b) 2880

(n - 2) * 180 = 2880

(n - 2) = 2880/180

(n - 2) = 16

n = 16 + 2

n =  18

c) 3960

(n - 2) * 180 = 3960

(n - 2) = 3960/180

(n - 2) = 22

n = 22 + 2

n = 24

d) 5040

(n - 2) * 180 = 5040

(n - 2) = 5040/180

(n - 2) = 28

n = 28 + 2

n = 30

Hi there! :)

[tex]\large\boxed{A. \text{ } y = 2x - 12}[/tex]

6x - 3y = 36

Solve for y:

begin isolating by subtracting both sides by 6x:

6x - 6x - 3y = 36 - 6x

-3y = 36 - 6x

Divide both sides by -3 to solve for y:

(-3y) / (-3) = (36 - 6x)/ (-3)

y = -12 + 2x

Rearrange:

y = 2x - 12, or choice A.

Answer:

They have the same amount of tokens after t = 7.6 hours

Step-by-step explanation:

Since Gavin initially has 50 token and rides the roller coaster three times per hour, he uses 3 token per hour. So, the number of token he losses after t hours is 3 token per hour × t hours = 3t. Thus, the number of tokens left after t hours is T = 50 - 3t

Since Gibson initially has 12 tokens and finds two tokens on the ground per hour, he gains 2 tokens per hour. So, the number of token he gains after t hours is 2 token per hour × t hours = 2t. Thus, the number of tokens he has after t hours is T' = 12 + 2t

To calculate the time t when they will have the same tokens, T must be equal to T', that is T = T'.

So, 50 - 3t = 12 + 2t

collecting like terms, we have

50 - 12 = 3t + 2t

38 = 5t

dividing both sides by 5, we have

t = 38/5

t = 7.6 hours

So, they have the same amount of tokens after t = 7.6 hours

Answer:

1. 0.25T

2. 0.25n

3. T - 0.25T

4. T - 0.25n

5. 0.75n × 0.5

Step-by-step explanation:

1. The dollar amount the club would have if they reached one-fourth of their goal.

Since the goal is to raise T dollars

One-fourth of T = ¼ × T = 0.25T

2. The dollar amount the club would have if every student at the school donated a quarter to the cause.

Let the number of students in the school be n

Since there are n students in the school, amount raised = ¼ × n = 0.25n

3. The dollar amount the club could donate to the cat shelter if they reached their goal and gave a quarter of the total donation to a dog shelter.

Since they reached their goal, the total amount they raised= T dollars

They gave a quarter of the total donation to a dog shelter = ¼T = 0.25T

Amount left to donate to the cat shelter =  T - 0.25T

4. The dollar amount the club would still need to raise to reach its goal after every student at the school donated a quarter.

Amount donated if every student donated a quarter = ¼n = 0.25n

Amount still needed = T - 0.25n

5. The dollar amount the club would have if three-fourths of the students at the school each gave 50 cents

Three-fourths of the students = ¾n = 0.75n

50 cents = 0.5 dollars

Amount raised if three-fourths of the students gave 50 cents = 0.75n × 0.5

Answer:

The value of each expression when x=3 will be -20 and -20.

Step-by-step explanation:

Given the expression

-4x-8

setting x=3

= -4(3)-8

=-12-8

=-20

Given the expression

-2(x+1)-2(x+3)

setting x=3

=-2(3+1)-2(3+3)

=-2(4)-2(6)

=-8-12

=-20

so we conclude that the value of both the expressions was -20 when we substituted the value x=3.

Therefore, the value of each expression when x=3 will be -20 and -20.

Answer:

Step-by-step explanation:

I'm a little confused by your question. But I solved the question this way.

y+12+2y-18+2y+16=180

Why 180° you ask? Because the angle sum interior of a triangle always measures 180°.

(y+2y+2y)+(12+−18+16)=180

5y+10=180

Subtract

5y+10−10=180−10

5y=170

divide

5y/5=170/5

y=34

Answer:

x + y + z = 123

Step-by-step explanation:

x:y:z = 7:2:5

Let x = 7a, y = 2a, z = 5a

Since x - z = 18

Therefore,

7a - 5a = 18

2a + 18

a = 18/2

a = 9

7a = 7*9 = 63

2a = 2*9= 15

5a = 5*9 = 45

x + y + z = 63 + 15 + 45

x + y + z = 123

Answer:

Polly=30

Andy=60

Phoebe=180

Step-by-step explanation:

Polly=x

Andy=2x

Phoeby 3(2x)=6x

x+2x+6x=270

9x=270

x=30

Polly=x=30

Andy = 2x=60

Phoebe=6x=180

Answer:

6x + 5y + 13 = 0.

Step-by-step explanation:

y = 5/6x + 7/6

Gradient = 5/6

Since the line is perpendicular to y = 5/6x + 7/6

then its gradient is -6/5.

Hence its equation is: point (-8,7).

y - 7 = -6/5(x -(-8))

multiplying through by 5 we get;

5y - 35 = -6(x + 8)

5y - 35 = -6x - 48

6x + 5y + 13 = 0

2) C

It's really easy to solve this problem all you have to do is long division with 4,274 and 51.

4,274 divided by 51 is = to 83 but it still has decimals leftovers meaning there would be a remainder and since we already found out 81 is part of the answer we know it won't be 91 and it has to be 83 with a remainder!

Answer:

use desmos.

Step-by-step explanation:

demos. All you have to do is out the equation into Desmos and it will graph it for you. You can look and learn.

Answer:

<1=83

<2=97

<3= 83 (given)

<4=97

<5=83

<6=97

<7=83

<8=97

Step-by-step explanation:

They give you the angle for 3 which is 83, so from there all you have to do is find the equivalent angles which are angle 1,5,7. Then for angles 2,4,6,8 you subtract 83 from 180 and you get 97.
