Answer:

Equation: y = 3x + 3.80

Cost of each bag: $3.75

Step-by-step explanation:

y = 3x + b

y = $15.05

x = cost of each bag

b = $3.80

3 = # of bags

15.05 = 3x + 3.80

11.25 = 3x

3.75 = x

The equation to determine x is y = 3x + 3.8

and cost of each apple bag is $3.75.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Total amount paid by Aiden = $15.05

Total amount paid for ice cream =  $3.80

Number of bags of apple = 3

So if x is the amount of each apple bag and y is the total amount paid by Aiden,

So,Cost of apple bags = 3x

And total amount = 3x + 3.8

or y = 3x + 3.8

this is the equation to determine x.

Now since, total amount paid is $15.05

⇒ 15.05 = 3x + 3.8

or,3x = 15.05 - 3.8

or 3x = 11.25

⇒ x = 11.25/3

⇒ x = $3.75

Thus,the equation to determine x is y = 3x + 3.8

and cost of each apple bag is $3.75.

Answer:

y = 4(degrees)

Step-by-step explanation:

90-60 = 30

30 = 8y-2

32 = 8y

4 = y

lets check

32-2 = 30+60 = 90

correct :D

Answer:

Step-by-step explanation:

3/4 = 0.75 pound

1 : 0.75 = x : 1

x = 1 * 1 : 0.75

x = 1.33

--------------check

1 : 0.75 = 1.33 : 1

1.33 = 1.33

the answer is good

Answer:

[tex]1 \frac{1}{3}lb \: sausage[/tex]

Step-by-step explanation:

What Iike to do is make it like a ratio.

So you have one pound of sausage per 3/4lb of cheese

[tex] \frac{1lb \: sausage}{( \frac{3}{4} )lb \: cheese} = \frac{sausage}{1lb \: cheese} [/tex]

Then you just make that sausage the subject of the equation by multiplying 1lb cheese to both sides of the equation, and you have your answer.

[tex]1lb \: cheese \times \frac{1lb \: sausage}{0.75 \: lb \: cheese} = sausage[/tex]

Answer:  " 4 − 3a " .

Answer:

[tex]y = 2 {(x + 2)}^{2} + 62[/tex]

Step-by-step explanation:

vertex form is

[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]

our original equation

[tex]2 {x}^{2} + 8x + 70[/tex]

first we will find the x value using the formula

[tex]x = - \frac{b}{2a} \\ - \frac{8}{2(2)} = - \frac{8}{4} = - 2 \\ x = - 2 = h[/tex]

plug the value of x back into the original equation to solve for y

[tex]y = 2 {x}^{2} + 8x + 70 \\ y = 2 ({ - 2}^{2} ) + 8( - 2) + 70 \\ y = 2(4) - 16 + 70 \\ y = 8 - 16 + 70 \\ y = 78 - 16 \\ y = 62 = k[/tex]

substitute this back into our vertex form and not forgetting the coefficient a = 2

[tex]y = 2 {(x - ( -2))}^{2} + 62 \\ y = 2 {(x + 2)}^{2} + 62[/tex]

A shipping container will be used to transport several 150-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24000 kilograms. Other shipments weighing 6400 kilograms have already been loaded into the container.

Answer:

[tex]x<=118[/tex]

Step-by-step explanation:

We already have [tex]10300[/tex] kilograms, we will add [tex]x*150[/tex] kilograms, and we need it to be less than or equal to [tex]28000[/tex].

So, the inequality is [tex]150x+10300<=28000[/tex].

We can subtract [tex]10300[/tex] from both sides to get [tex]150x<=17700[/tex].

We then lastly divide by [tex]150[/tex] on both sides to get [tex]x<=118[/tex].

So, the answer is [tex]\boxed{x<=118}[/tex] and we're done!
