Translating "The tax is some percent of the phone's price" into an equation, we get:

   42.42 = p · 499

If we divide both sides by 499, we get

   0.085 ≈ p

We can check by finding 8.5% of 499:

   0.085 · 499 = 42.415, which rounds to 42.42

So the tax rate was 8.5%.

= 10x − 1

Step-by-step explanation:

Let's simplify.

2 + 2x(5) − 3

= 2+10x + −3

Combine Like Terms:

= 2 + 10x + −3

= (10x) + (2 + −3)

= 10x + −1

= 10x − 1

Answer:

5/36

Step-by-step explanation:

Answer:

the probability of getting a total greater than 8 is  10/36=5/18

Step-by-step explanation:

Of the 36 different possible results of rolling a die twice, 10 of them have a total greater than 8.

Therefore, the probability of getting a total greater than 8 is  10/36 which equals 5/18

Answer:

RM1,600

Step-by-step explanation:

2000 * 0.20= 400

2000-400= 1600

$15.08

As the value 226.20 is the total of all wages, you can work out the mean.

Mean averages are usually worked out as the total / number of values.

Because you already know the total is 226.20 and the number of values is 15 different wages, divide 226.20 by 15 to get $15.08.

Answer:

we need 6 cups of cranberry juice for 12 gallons of punch

Answer:

y = 19/36

Step-by-step explanation:

Assuming that what you want is the value of y, you can pass all the right side stuff to the left, and the y to the right:

2/3 + 15/6 = 6y

Then you can sum the fractions on the left by using the same denominators:

4/6 + 15/6 = 6y       ==>      19/6 = 6 * y

then  you can pass the 6 that is multiplying on the right to the left - now dividing:

y = 19/36

Answer:

  y = 5/12

Step-by-step explanation:

  2/3 - 6y = -1 5/6 . . . . . given

  4 -36y = -11 . . . . . . . . . multiply by 6

  15 = 36y . . . . . . . . . . add 36y+11

  15/36 = y = 5/12 . . . . divide by 36, reduce the fraction

Check

  2/3 -6(5/12) = -1 5/6

  4/6 -15/6 = -11/6 . . . . true

Answer:

Step-by-step explanation:

you add the numbers to gether

Answer:

B) A = 52.3°, b = 1.7 m, c = 2.8 m

Step-by-step explanation:

We know that it is a right angle triangle because C = 90°

because of that we can do 180 - 90 + 37.7

which is a=52.3

Because it is a right angle triangle, we can use sin, cos,tan

I will use sin to find the side of c

2.2 is a

sin 52.3 = 2.2/x

x= 2.2/ sin 52.3

x=2.78

You could do cos or tan but the pythagorean theorem for me is much faster

so it looks like this, a^2+b^2 =c^2

in this case we have both a and c we want b

so we rearrange

c^2-a^2=b^2

2.78^2-2.2^2= b^2

[tex]\sqrt{2.89}[/tex]=b

1.7=b

therefore it would be this option B) A = 52.3°, b = 1.7 m, c = 2.8 m

Answer:

Step-by-step explanation:

Recall that a proportional relationship is a relationship between two quantities in which the ratio of one quantity to the other quantity is constant. ... When ratios between quantities are not constant, a relationship may be linear but not proportional and the graph does not pass through the origin.

Answer:

y=4x-17

Step-by-step explanation: Distribute the 4(x-5)

QUESTION. What is the Scale factor of 35 to 42

--------------------------------------

[tex]\boxed {\tt 25/35}[/tex]

---------------------------------------

The Scale Factor of 35/42 is the relative difference of one fraction or number (a) to another fraction or number prime (a′). In other words, 35/42 is what you multiply (number a) by to get (number a prime).

In a multiplication problem, we have a multiplier, multiplicand, and a product. You could say that (a) is the multiplier, the Scale Factor of 35/42 is the multiplicand, and (a′) is the product:

multiplier × multiplicand = product

multiplier × scale factor = product

a × 35/42 = a′

In the calculator below, you can enter the multiplier (a) as a fraction. We will then multiply it by the Scale Factor of 35/42 and give you the product (a′) in its simplest form possible.

Step-by-step explanation:

We know that angles on a straight line add up to 180, so:

5x+5+5x+5=180

Simplify

10x+10=180

Solve

Take away 10 from both sides

10x=170

Divide 170 by 10

x = 17
