Answer:

x=67 y=113 x=52

Step-by-step explanation:

85+28= 113

180-113=67

67= x

67+28=95

95+85=180

y= 28+ 85 =113

113+15= 128

180-128=52

52=x

Answer:

G(x) = 2x - 3 has a linear inverse which is a function.

k(x) = -9x2 has a square root inverse that is a function on only the interval x < 0.

Step-by-step explanation:

The inverse of a function is a reflection across the y=x line. This results in switching the values of the input and output or (x,y) points to become (y,x). This can be done algebraically in an equation as well. Begin by switching the x and y in the equation then solve for y.

x = 2y - 3 -------> y = x/2 + 3/2 is linear and a function.

-9y2 = x --------> y = √(-x/9)  is a square root that is a function on only the interval x < 0.

Absolute value does not have an inverse function.

x = -20 is a vertical line which is not a function.

Step-by-step explanation:

substitute 4 for g. 4x5= 20 and 20 is definitely less than or equal to 25

Answer:

yes

Step-by-step explanation:

Given

5g ≤ 25

If g = 4 then

5g = 5 × 4 = 20 and

20 ≤ 25

Thus g = 4 is a solution of the inequality

Answer:

1. $8.30

Step-by-step explanation:

so 3 hats were purchased and each cost 15.50 so

15.50*3=46.50

and the rest of the 96.30 is 6 keychains so

96.30-46.50=49.80

and there is 6 keychains

49.80/6=8.30

Each key chain was $8.30

Claire's answer is unreasonable because when we got the price of the keychains all together in Claire's mind the total for the keychains would be $4.98, which we clearly got the total for the keychains at $49.80.

The cost of each keychain is  $5.79 which parks bought.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Parks spent $96.30 on 3 hats and 6 key chains and the cost of each hat is $15.50 and assuming the cost of each key chain to be 'x'.

Therefore, The expression that represents this context is,

3×15.50 + 6x = 96.30.

6x = 96.30 - 46.50.

6x =  49.8.

x = 49/8.6.

x = 5.79.

So, The cost of each key chain is $5.79.

Answer:

DE = 34

AC = 68

Step-by-step explanation:

since DE are midpoints, you can create this equation: 2(8x + 2) = 20x - 12

solve:

16x + 4 = 20x - 12

16x + 16 = 20x

16 = 4x

4 = x

plug this into both equations to find each side:

DE: 8(4) + 2 = 34

AC: 20(4) - 12 = 68

we know our answer is right because AC is twice as long as DE

Answer:

y = [tex]\frac{8}{3}[/tex] x + [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{8}{3}[/tex] x + 2 ← is in slope- intercept form

with slope m = [tex]\frac{8}{3}[/tex]

Parallel lines have equal slopes , thus

y = [tex]\frac{8}{3}[/tex] x + c ← is the partial equation

To find c substitute (- 2, - 5) into the partial equation

- 5 = - [tex]\frac{16}{3}[/tex] + c ⇒ c = - 5 + [tex]\frac{16}{3}[/tex] = [tex]\frac{1}{3}[/tex]

y = [tex]\frac{8}{3}[/tex] x + [tex]\frac{1}{3}[/tex] ← equation of parallel line

Answer:

72 dogs

Step-by-step explanation:

3 dogs/2 cats = x dogs/48 cats

Cross Multiply

3/2 x x/48

2x=144

x=72

Answer:

72 dogs

Step-by-step explanation:

First turn 3:2 into a fraction:

3/2

Then you can make the equation a proportion question, which is much eaiser to handle.

3/2=x/48  (I recommend writing this out so it will be easier to see)

Then you cross multiply, or multiply by the numerator of the first fraction by the denominator of the second, and the denominator of the first fraction by the numerator of the second.

Multiply 2 by x, which becomes 2x.

Multiply 3 by 48, which is 144

This becomes... 2x=144

You then solve with equation by dividing 144/2 and getting 72.

Meaning x=72 dogs

Step-by-step explanation:

Answer: 1 13/24

Step-by-step explanation:

We need to convert 2/3 and 7/8 to have a common denominator. They both have a common denominator of 24 so...

We convert:

2/3 x 8/8=16/24

7/8 x 3/3 = 21/24

Then we add:

16/24 + 21/24 =37/21

Then we convert to a mixed number:

37/24= 1 13/24

Answer:

E: x = 13

F: x = 1.5 or 3/2

Step-by-step explanation:

This is for E:

x + 2/3 = 5

All you do is first multiply 5 * 3

and you will get 15

x + 2 = 15

Then you subtract from 15

15 - 2 = 13

So x = 13

This is for F:

10(x - 1) = 5

So all you do is distribute the 100 with x -1

10 * x = 100x

10 * -1 = 100

10x - 10 = 5

Then you add 10 to 15 because the number is -10

5 + 10 = 15

10x = 15

Now you divide by 10 on both sides

10x/10 = 15/10

10x/10 = x

15/10 = 3/2

So the answer for F is 3/2 or 1.5

Answer:

μ = 0.4

Standard deviation σ = 0.0512 (Approx)

Step-by-step explanation:

Given:

Sample size n1 = 100

Sample size n2 = 200

Proportion p1 = 0.7

Proportion p2 = 0.3

Find:

Standard deviation σ

Computation:

μ = p2 - p1

μ = 0.7 - 0.3

μ = 0.4

Standard deviation σ = √p1(1-p1)/n1 + p2(1-p2)/n2

Standard deviation σ = √0.7(1-0.7)/100 + 0.3(1-0.3)/400

Standard deviation σ = √0.0021 + 0.000525

Standard deviation σ = √0.002625

Standard deviation σ = 0.0512 (Approx)

Answer:

A sandwich is $3.50 and the price of a drink is $2.50

Step-by-step explanation:

Create a system of equations where s is the price of a sandwich and d is the price of a drink:

9s + 5d = 44

15s + 7d = 70

Solve by elimination by multiplying the top equation by 7 and the bottom equation by -5, then adding them together:

63s + 35d = 308

-75s - 35d = -350

Add them together:

-12s = -42

s = 3.5

Then, plug in 3.5 as s into one of the equations to solve for d:

9s + 5d = 44

9(3.5) + 5d = 44

31.5 + 5d = 44

5d = 12.5

d = 2.5

So, a sandwich is $3.50 and the price of a drink is $2.50

Answer:

A sandwich is $3.50 and the price of a drink is $2.50

Answer:

200 oz

Step-by-step explanation:

Just use the equation

0.32x=200

The number of 32% which result in 60 oz would be 18.75

Suppose the value of which a thing is expressed in percentage is "a' the percent that considered thing is of "a" is b%. Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts.

We need to find the number that is state 32% of number weight is 60 oz​

Let the unknown number is represneted by b.

It can be written by;

32% x b = 60

32/100 x b = 60

0.32 x b = 60

b = 60/0.32

b = 18.75

Therefore, the number would be 18.75
