Answer:

? = 4.492385

About 4.5 pounds

Step-by-step explanation:

m = money spent

80 - 44.6 = m

m = 35.4

m / 7.88 = ?

? = 35.4 / 7.88

? = 4.492385

About 4.5 pounds

Answer:

She bought 5 pounds of coffee

Step-by-step explanation:

If you subtract 80-40.60 you would get 39.4/39.40 and since each pound was 7.88 you divided 39.40 and 7.88 and you would get 5

Answer:

y = 3x + 1

Step-by-step explanation:

(2, 7); 3x - y = 5

(x₁, y₁)

3x - y = 5

-3x           -3x

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

-y = -3x + 5

÷-1    ÷-1   ÷-1

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

y = 3x - 5

y - y₁ = m(x - x₁)

y - 7 = 3(x - 2)

y - 7 = 3x - 6

  +7          +7

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

y = 3x + 1

I hope this helps!

Answer: y=3x+1

Step-by-step explanation:

[tex]3x-y=5\\3x-y+y=5+y\\3x=5+y\\3x-5=y+5-5\\3x-5=y\\So, \ y=3x-5\\[/tex]

A line parallel to line y=3x-5 will look like this: y=3x+b

The line passes throught the point (2,7), hence:

[tex]7=3(2)+b\\7=6+b\\7-6=6+b-6\\1=b\\Thus,\ b=1\\y=3x+1[/tex]

The angle AOB has a measure of 72 degrees

The formation of angles is as a result of the intersection of multiple lines intersect.

The given parameters are:

The above means that

AOB = BOC

So, we have

6x - 12 = 3x + 30

Evaluate the like terms

3x = 42

Divide by 3

x = 14

Substitute x = 14 in AOB= 6x -12°

So, we have

AOB= 6 x 14  -12°

Evaluate

AOB= 72°

Hence, the measure of the angle is 72 degrees

Tate and Nathan will leave $ 19.48 to the server to cover up the bill and the tip when they go out to dinner at Red Robin.

As given in the question,

Since Tate and Nathan both order burgers for $12.49 each,

Total amount payable is

$12.49 + $12.49= $24.98.

Now 18% tip is equal to

18% of $24.98

(18/100) × 24.98

= $4.4964

= $4.50 (rounded to nearest cent).

Total gross amount payable (including 18% tip) is

24.98 + 4.50 = $29.48.

Now subtracting the birthday coupon for $10.00 off,

the net amount payable in the bill is

29.48 - 10.00

= $ 19.48

= 19.48 cents

Therefore, after using the coupon, they will leave the server $19.48 to cover the bill and the tip.

On subtracting "3a – 7b + 12c" from "-5a – 21b + 3c" we get -

- 8a - 14b - 9c

Subtraction is an arithmetic operation that represents the operation of removing objects from a collection. Subtraction is signified by the minus sign −.

Given is to subtract "3a – 7b + 12c" from "-5a – 21b + 3c".

Assume that -

A = 3a – 7b + 12c

B = -5a – 21b + 3c

B - A = (-5a – 21b + 3c) - (3a – 7b + 12c)

B - A = -5a - 21b + 3c - 3a + 7b - 12c

B - A = -5a - 3a - 21b + 7b + 3c - 12c

B - A = - 8a - 14b - 9c

Therefore, on subtracting "3a – 7b + 12c" from "-5a – 21b + 3c" we get -

The value of the given function [tex]log_6x+log_6(x-1)=1[/tex] is x = 3 or x =-2

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x. In the simplest case, the logarithm counts the number of occurrences of the same factor in repeated multiplication; e.g. since 1000 = 10 × 10 × 10 = 10^3, the "logarithm base 10" of 1000 is 3, or [tex]log_1_01000=3[/tex].

We know that

Log (a) + log (b) = log (ab)

So, [tex]log_6x+log_6(x-1)=1[/tex]

[tex]log_6(x(x-1))=1\\log_6(x^2-x)=1\\x^2-x=6^1\\x^2-x-6=0\\[/tex]

(x-3)(x+2)=0

The equation of the line that passes through the point (8, 5) and perpendicular to y = −12x +7 is y = (1/12)x + 13/3.

We know that,

The product of the slopes of two perpendicular lines is -1.

The slope intercept form of a line is given by :-

y = mx + c

Comparing it with y = -12x + 7

We get,

m = -12 (slope of the line)

c = 7 (y-intercept of the line)

Let the slope of the line perpendicular to the given line be n.

Hence, we can write,

(-12)*n = -1

n = 1/12

Also, the line passes through (8,5).

Hence, we can write,

5 = (1/12)(8) + c

5 = 2/3 + c

c = 5 - 2/3 = 13/3

Hence, the equation of the line is given by :-

y = (1/12)x + 13/3
