The coffee shop used 52 pounds of Type A coffee.

Step-by-step explanation:

Cost of Type A coffee per pound = 5.25

Cost of Type B coffee per pound = 4.10

Total pounds used in blend = 142

Total cost = 642.00

Let,

x be the pounds of Type A coffee used

y be the pounds of Type B coffee used

According to given statement;

x+y=142 Eqn 1

5.25x+4.10y=642.00 Eqn 2

Multiplying Eqn 1 by 4.10

$4.10(x+y=142)\\4.10x+4.10y=582.20\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(5.25x+4.10y)-(4.10x+4.10y)=642.00-582.20\\5.25x+4.10y-4.10x-4.10y=59.80\\1.15x=59.80\\$

Dividing both sides by 1.15

$\frac{1.15x}{1.15}=\frac{59.80}{1.15}\\x=52\\$

The coffee shop used 52 pounds of Type A coffee.

Answer: A. f(n) = 4 ∙ 2n-1

Step-by-step explanation:

because the 1st term is 4 according to your image, and then you will have to multiply that by its common difference and using your table, to get from 4 to 8 then 8 to 16 you would multiply by 2, and you would finally multiply that by n or known as the number of terms and 1 making the equation. f(n) = 4 ∙ 2n-1 I hope this is very helpful for everyone.

One number added to three times another number is 24. Five times the first number added to three times to other number is 36. Fi

Marrrta [24]

The numbers are 3 and 7

Step-by-step explanation:

Let the first number be x and the second number be y

Then according to given statement

One number added to three times another number is 24

x+3y=24 Eqn 1

Five times the first number added to three times to other number is 36

5x+3y=36 Eqn 2

Subtracting Equation 1 from equation 2

$5x+3y-(x+3y)=36-24\\5x+3y-x-3y=12\\4x=12$

Dividing both sides by 4

$\frac{4x}{4}=\frac{12}{4}\\x=3$

Putting x=3 in equation 1

$3+3y=24\\3y=24-3\\3y=21$

Dividing both sides by 3

$\frac{3y}{3} = \frac{21}{3}\\y=7$

Hence,

The numbers are 3 and 7
