Given:

Total number of tickets = 80

Ratio of winning tickets to losing tickets is 2 : 8.

To find:

The number of tickets of each kind in the bag.

Solution:

Let the number of winning and losing tickets are 2x and 8x respectively.

Total number of tickets = 80

[tex]2x+8x=80[/tex]

[tex]10x=80[/tex]

Divide both sides by 10.

[tex]x=\dfrac{80}{10}[/tex]

[tex]x=8[/tex]

Now,

Winning tickets : [tex]2(8)=16[/tex]

Losing tickets : [tex]8(8)=64[/tex]

Therefore, the winning and losing tickets are 16 and 64 respectively.

Answer:

-1 option D (no solution)

Step-by-step explanation:

2(x + 7)2/3 = 8

2(X+7)2/3=8

4(X+7)=24

4x+28=24

4x=24-28

4x=-4

X=-4/4

X=-1

So the answer is -1

Answer:

[tex]y \frac{1}{2}x - 4 [/tex]

Answer:

y = 2 - 2x

Step-by-step explanation:

Answer:

A. y = -2x + 2

Step-by-step explanation:

4x + 2y = 4

Move 4x to the other side of the equation.

2y = 4 - 4x

Divide the whole thing by 2 to get y by itself.

y = 2 - 2x

which can also be written as

y = -2x + 2

[tex]y = - 3x + 4[/tex]

Add sides 3x

[tex]y + 3x = 3x - 3x + 4[/tex]

[tex]3x + y = 4[/tex]

_________________________________

[tex]1) \: 3x + y = 4[/tex]

[tex]2) \: - 4x + y = - 10[/tex]

Multiply sides of the (( equation 2 )) by - 1

[tex]1) \: 3x + y = 4[/tex]

[tex]2) \: 4x - y = 10[/tex]

Add up equations

[tex]3x + 4x + y - y = 4 + 10[/tex]

[tex]7x = 14[/tex]

Divide sides by 7

[tex] \frac{7x}{7} = \frac{14}{7} \\ [/tex]

[tex]x = 2[/tex]

Put the value of x in one of the (1) or (2) equations to find the value of y .

I put it in equation 1 :

[tex]3x + y = 4[/tex]

[tex]3(2) + y = 4[/tex]

[tex]6 + y = 4[/tex]

[tex]y + 6 = 4[/tex]

Subtract sides 6

[tex]y + 6 - 6 = 4 - 6[/tex]

[tex]y = - 2[/tex]

And we're done...

Answer:

(-2,3) if your doing substitution

(-2,3) for Elimination

Step-by-step explanation:

Answer:

y + 3 = 2 (x - 4)

Step-by-step explanation:

y - y₁ = m (x - x₁)

substitute (4, -3) in for (x₁, y₁)

y - (-3) = m (x - 4)

substitute the slope (2) in for m (m=slope) and simplify (y - (-3)) to (y +3) because subtracting a negative is the same as adding a positive

y + 3 = 2 (x - 4)

and that's your final answer! hope this helped :)

47+53 = 100

ratio of students = 47

[tex]47 \times \frac{100}{100} = 47\%[/tex]

Hence, 47 % of the marching band is students.

Answer:

The difference in price between a small pizza and a medium pizza is $0.81

Step-by-step explanation:

Small pizza

Side = 5inch

Area =  25 sq.in

Cost = $4 +0.04*25

        = 4 + 1.25  = $5.25

Medium pizza

Side = 8inche

Area = 64 sq.in

Cost = 3.50 + 0.04*64 = $6.06

Difference = Medium pizza - small pizza

                  = 6.06 - 5.25

                   = $0.81

Hey there! It would be 44% decrease...

Explanation:

So we know that 9 would be 100%. So what is the percent of change?

So let divide 5 with 9. 5 divide 9 would be 0.56.

Great, now we can subtract 100 with 0.56 since we know that 56% is 5. 100-56 is 44. This means that the percent decrease would be 44%.

Final Result: 44%

The percent change from 5 to 9 is 80%.

Percentage is a measurement to find the value of a given number out of hundred.

Given that,

The original number is 5.

The number changes to 9 .

Increase in number = 9-5 = 4

The percentage change = 4/5×100 = 400/5 = 80%

The percentage change is 80% from 5 to 9.

Answer: Percentage error = -5.9%

Step-by-step explanation:

Step 1

Percentage error =Approximate Value − theoretical  Value / Theoretical value    ×  100%

or

Percentage error = Assumed number - Result number / Result number x 100

Given  Assumed number / Approximate Value=  32o F

Result number/ Theoretical value= 34o F.

Step 2---

Percentage error = (32 - 34)/ 34  x 100

= - 2/34 x 100

= - 5.88%

Joshua  was in error by - 5.88 % which when rounded to nearest tenth gives - 5.9%.
