Answer:

The equation is;

C = kg

c is the cost in $

k is the proportionality constant $/can

g is the number of cans

cost of 5 cans of coffee is $46.25

Step-by-step explanation:

From the question, 2 cans of ground coffee costs $18.50

Let c be the cost and g be the number of ground coffee

18.50 = k * 2

where k is the constant of proportionality;

k = 18.5/2

k = 9.25

So, the cost of 5 coffee cans will be;

c = 9.25 * 5 = $46.25

Answer:

x = 61

Step-by-step explanation:

0.5(x + 7) + 9 = 43

0.5x + 3.5 + 9.0 = 43

0.5x + 12.5 = 43.0

0.5x = 30.5

x = 30.5 / 0.5

x = 61

The solution to the value of x in the equation is 61

In a mathematical concept, an algebraic expression consists of variables, constants with their arithmetic operations.

From the given parameters

0.5(x + 7) + 9 = 43

Open brackets

0.5x + 3.5 + 9 = 43

0.5x + 12.5 = 43

0.5x = 43 - 12.5

0.5x = 30.5

x = 30.5/0.5

x = 61

Answer:

I believe it is Y=30+2x

Step-by-step explanation:

Since the $30 is given no matter what, we can use it as b.

Since slope always changes, we use it as our m.

X= amount of people

2= charge per person

If there were 5 people there, the equation would look like this: y= $2(5)+$30

The dollar signs are just an aid.

Answer:

Y=2x+30

Step-by-step explanation:

The b is 30

While the slope is 2

Using y=mx+b that will be your answer.

A 7-pack of tickets to the zoo costs $78.61. Therefore, the unit price of ticket to the zoo $11.23.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into same number of parts.

Given that a 7-pack of tickets to the zoo costs $78.61.

To find the unit price;

Cost of one pack of ticket to the zoo = total cost of 7 pack of tickets / number of tickets

Cost of one pack of ticket to the zoo = $78.61 / 7

Cost of one pack of ticket to the zoo = $11.23

Therefore, the unit price of ticket to the zoo $11.23.

Step-by-step explanation:

10 -2b^2

Let b=-3

10 - 2( -3)^2

Do the exponent first

10 -2(9)

Multiply

10 -18

Subtract

-8

Answer:

- 8

Step-by-step explanation:

Given

10 - 2b² ← substitute b = - 3 into the expression

= 10 - 2(- 3)²

= 10 - 2(9)

= 10 - 18

= - 8

Answer:

∠A =  115°

∠B =  65°

∠C =  115°

∠D =  65°

Step-by-step explanation:

The figure given is of parallelogram.

We need to find measure of each interior angle.

We are given:

∠A = (2x-15)°

∠B = x°

∠C = (2x-15)°

∠D = x°

We need to find measure of ∠A , ∠B, ∠C, ∠D

We know that sum of all angles of parallelogram = 360°

So, we can write: ∠A +∠B+ ∠C+ ∠D = 360°

Now putting their values and finding value of x first:

[tex]2x-15+x+2x-15+x=360\\Combining\:like\:terms:\\2x+x+2x+x-15-15=360\\6x-30=360\\6x=360+30\\6x=390\\x=\frac{390}{6}\\x=65[/tex]

So, we get x= 65

Now finding measure of each angle:

∠A = (2x-15)° = 2(65)-15 = 130-15 = 115°

∠B = x° = 65°

∠C = (2x-15)° = 2(65)-15 = 130-15 = 115°

∠D = x°= 65°

Answer is:

∠A =  115°

∠B =  65°

∠C =  115°

∠D =  65°

Answer:

the number of additional she needed is 135

Step-by-step explanation:

The computation is shown below:

GIven that

40 flowers of 16%

So for 100% it would be

= 40 ×100 ÷ 16

= 250

Now she needs to make is

= 70% - 16%

= 54%

Now the additional would be

= 250 × 54%

= 135

Hence, the number of additional she needed is 135
