Answer:

x=5

Step-by-step explanation:

7x - 4y = 23 and x + y = 8

Multiply the second equation by 4

4x + 4y = 32

Add this to the first equation

7x - 4y = 23

4x + 4y = 32

Answer:

a)....it would cost 12 dollars

the equation is.... 2x 6(number of downloads)

b) C = 15 + (dx0.5)

c) the graph represents gamers price model

d) gamers would be cheapest

gamers would be 8 x 2 = 16

gameworld would be 15(monthly subs) plus 0.50 x 8 (4 dollars) = 19

e) totally depends upon the number of games downloaded by each person.

for up to 10 games per month Justin is on the best deal

exactly 10 games per month makes both deals equal

over 10 games per month Kenny is on the best deal

Answer:

1 / 2 or 0.5

Step-by-step explanation:

use the formula ; m = y2 - y1 / x2 - x1

where y2 = 10

y1 = 9

x2 = 5

x1 = 3

===================================================

Work Shown:

A = probability of landing on an odd number

A = 5/9 because there are 5 odd numbers out of 9 total

B = probability of getting heads

B = 1/2

C = landing on 3 on the spinner

C = 1/9

Multiply the values of A,B,C

A*B*C = (5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162

Note: The fraction 5/162 converts to the approximate decimal 0.03086 which then converts to 3.086%, when rounding to the nearest tenth of a percent we get 3.1%

Answer: C) $450

Step-by-step explanation:

If her rent is 30% of her total budget we can multiply by 0.3 to find how much is spent on rent.

1500x0.3=450

Alissa spends $450 on rent.

Answer:

C

Step-by-step explanation:

1. Find how much 30% of $1500

(30/100) x $1500 or ($1500 x 100)/30

2. Finish.

Answer:

if this was a equation you would first subtract 12 from the other number then divide it by 3

Answer:

3(x+4)

Step-by-step explanation:

Check 3(x+4), when you use the distributive property, you get 3x + 12, so this is correct. (sorry, I'm really bad at explaining...)

Answer:

The answer is Yes .. Ron is correct

Step-by-step explanation:

This is because each side of the outer square is 2 units summing up to 8 units. So dividing each into two equal parts give 1 unit each.

Each side of the inner square divides the outer square into two making each side 1 unit.

The inner square thus takes 1 unit for it's side summing the perimeter to 4 units.

Answer:

8:6

Step-by-step explanation:

If 8 out of 14 students are boys then the remaining number of students must be girls

So

14-8= 6

There are 6 girls out of the 14

So as a ratio of boys to girls

8:6

Answer:

8 : 6 <or> 4 : 3

Step-by-step explanation:

8 : 6 <or> 4 : 3

Since there are 8 boys out of 14, if you minus them , the answer will be the number of girls out of 14.

In the diagram below, ΔABC ≅ ΔDEF. Therefore, by CPCT, ∠B = ∠E.

Corresponding parts of congruent triangles or CPCT is used to denote the relation between the sides and the angles of two congruent triangles.

Since, ΔABC ≅ ΔDEF,

AB = DE

BC = EF

AC = DF

∠A = ∠D

∠B = ∠E

∠C = ∠F

Step-by-step explanation:

[tex]Florence \ washed \ 3\ cars \ and\ earned\ = \$ x\\\\[/tex]

[tex]Cost\ of \ washing \ one \ car = \frac{x}{3}[/tex]

[tex]Anona \ washed \ 5 \ cars \ and \ earned \ 16 \ more \ than \ Florence = x + 16[/tex]

[tex]Cost\ of \ washing \ one \ car \ by \ Anona = \frac{x +16}{5}[/tex]

[tex]Cost \ of \ washing \ one \car = \frac{x}{3} = \frac{24}{3} = \$ 8[/tex]

Therefore ,

                 Florence earned $24

Answer:

w = 5.2

Step-by-step explanation:

4(2.25w + 3.1) - 2.75w = 44.9

9w + 12.4 - 2.75w = 44.9

6.25w + 12.4 = 44.9

6.25w = 32.5

w = 5.2

4(2.25w+3.1)-2.75w=44.9

9w+12.4-2.75w=44.9

9w-2.75w+12.4=44.9

44.9-12.4=32.5

9w-2.75w=32.5

6.3w/6.3=32.5/6.3

Answer:

0.17

Step-by-step explanation:

41×cos(D) = 9

cos(D) = 9/41

=>

in a circle with the radius of 41 the point on the circumference of the circle for the angle D has an x-distance from the center of the circle of 9.

therefore, cos(D) = that x-distance divided by the radius (as the trigonometric functions only deliver the values for the norm circle with radius 1).

what is the y-distance (sin(D)×41) ?

r² = x² + y²

41² = 9² + y²

1681 = 81 + y²

1600 = y²

y = 40

therefore, sin(D) = 40/41

tan(D) = sin(D)/cos(D)

you know how to divide 2 fractions with each other ?

by multiplying the 2 outer factors (to top-most and bottom-most) as the top part of the result, and by multiplying the 2 inner factors for the bottom part of the result.

(40/41 - 9/41) / (40/41 / 9/41) =

= 31/41 / (40×41 / 9×41) = 9×41×31 / 40×41×41 =

= 9×31 / 40×41 = 279 / 1640 ≈ 0.17
