what is the answer to the problem?

Answer:

$3.78 tip and $7.56

Step-by-step explanation:

42%=0.42

0.42 X 9 = 3.78

0.42 X 18= 7.56

⇒If you are to check carefully you will find that b-a= -(a-b)

⇒meaning in order to obtain the equation of b-a we multiply the whole equation of a-b by -1

[tex]-(a-b)=-(50\\-a+b=-5\\b-a=-5[/tex]

hope this helps

Answer:

The values can be infinite, but for this to be true, a has to be 5 more than b, so if you subtract them, b-a will always equal -5 if a-b=5

Step-by-step explanation:

Example:

A=10

B=5

10-5=5     5-10= -5

Or:

A=15

B=10

15-10=5    10-15= -5

This can go on forever by increments of 5, as long as they are 5 apart.

Answer:

y= (-2/3)x+5

Step-by-step explanation:

We can use slope-intercept form to figure this out. y=mx+b

First, the y-intercept is given (0,5). y-int=5

To find the slope, we need any 2 points.

[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

If we use (0,5) and (3,3)

[tex]\frac{3-5}{3-0} =\frac{-2}{3}[/tex]

Put into slope-intercept form y=mx+b

[tex]y=\frac{-2}{3}x+5[/tex]

Answer:

Step-by-step explanation:

y = -0.666666667x+5

or

y = -⅔x +5

how?

well as you can see on the first box (0,5)

we can already know by this the equation will look like

y = _x +5

since if x is 0, we will already have +5

now onto the next box to help us

(1.5,4)

lets subtract 5 from 4 to find out what the slope will be

4-5=-1 and then divide that by our x

1 / 1.5 = -0.666666667

so our equation is

y = -0.666666667x+5

or

y = -⅔x +5

(not sure if you can understand from my explanation but please trust, this is right)

The measure of <Y is 38.

According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the interior angles in a triangle is always 180, regardless of whether it is acute, obtuse, or right.

One of the most commonly applied properties in geometry is the triangle's angle sum property.

Given:

m∠X = 47°, m∠Y = (2x − 18)°, and m∠Z = (5x − 45)°.

Using angle sum property

m<X + m<Y + m<Z = 180

47 + 2x- 18 + 5x - 45= 180

7x -16=180

7x= 180+16

7x= 196

x= 196/7

x= 28

So, the measure of <Y = 2x- 18 = 2(28) - 18 = 56-18 = 38

Hence, the measure of <Y is 38.

The equation y = 360(1.03)^x represents the amount of money in Josiah’s account after x years.

Compound interest is the type of interest in which the interest is taken from the principal amount as well as the accumulated interest from the previous years.

Here, we have,

we know that,

The formula for finding the total amount using compound interest is shown below :

A = P(1 + r)^t

Where A is the total amount,

P is the principal amount,

r is i/100 and,

t is the number of years.

Now we can make a formula from the given information. Substitute the values of all the variables:

y = 360(1 + 3/100)^x

⇒ y = 360(1.03)^x

Compare this to the given equations. We can clearly see that equations A, B, and C are wrong. But we can see that option D is correct.

Therefore, we can say that the equation y = 360(1.03)^x represents the amount of money in Josiah’s account after x years. The correct answer is option D.

Inequality shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

The integer that can make the inequality true is m = -8

(1/4)(m - 4) ≤ (1/8)(m - 16)

1/4 x -12 ≤ 1/8 x -24

-3 ≤ -3

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

One-fourth times the difference between m and four is less than or equal to one-eighth times the difference between m and sixteen

This can be written as,

(1/4)(m - 4) ≤ (1/8)(m - 16)

The number that will make the inequality true.

S = {−32, −8, 16, 32}

We will check each value.

m = -32

1/4 x -36 ≤ 1/8 x -48

-9 ≤ -4

Not true

m= -8

1/4 x -12 ≤ 1/8 x -24

-3 ≤ -3

True

m = 16

1/4 x 12 ≤ 1/8 x 0

3 ≤ 0

Not true

m = 32

1/4 x 28 ≤ 1/8 x 16

7 ≤ 2

Not true

Thus,

The integer that can make the inequality true is m = -8

(1/4)(m - 4) ≤ (1/8)(m - 16)

1/4 x -12 ≤ 1/8 x -24

-3 ≤ -3

Answer:35

Step-by-step explanation:

The integer in the set S:{−24, 2, 20, 35} that will make the inequality five-sixths m minus five is less than one-half m plus 3 false is 35What is inequality?Inequalities are created through the connection of two expressions. It should be noted that the expressions in inequality aren't always equal. Inequalities imply that the expressions are not equal. They are denoted by the symbols ≥  <  >   ≤.In this case, based on the information we will replace m with 35. This will be illustrated thus:= 5/6(35 - 5) < 1/2(35 + 3)= 5/6(30) < 1/2(38)= 25 < 19In this case, 25 isn't less than 19. Therefore, 35 is the correct integer.
