1 pizza should cost $5.65

Pizza is $5.65 then bottle of coke is $2.45

3 pizzas and coke: ($5.65*3) + $2.45 = $19.4

I solved this by setting up and solving a system of linear equations:

Variables: p = pizza, c = coke

p = c+3.2

3p+c = 19.4

Solve by substitution

3(c+3.2) + c = 19.4

4c+9.6 = 19.4

c = 2.45

Re-plug in:

p = 2.45+3.2

p = 5.65

3-1/8a=1/4<br><br> Pleasseeee help
Vika [28.1K]
3 - 1/8a = 1/4

The goal is to isolate "a" and its coefficient to make the simplification process easier.

Start by subtracting 3 from both sides:

3 - 3 - 1/8a = 1/4 -3

-1/8a = 1/4 - 3

Next, multiply 3 by 4/4 to convert it into a fraction:

-1/8a = 1/4 - [3 • (4/4)]

-1/8a = 1/4 - 12/4

-1/8a = - 11/4

Multiply both sides by -8:

(-8) -1/8a = - 11/4 (-8)

a = 88/4 = 22

Therefore, a = 22.

hjlf

Answer:

f(x) is the total cost and x is the number of peaches.

Step-by-step explanation:

We know that each peach costs $0.75.  This means the expression 0.75x represents the total cost of peaches; this makes x represent the number of peaches.

We also know that $2.25 is the cost of juice.  Adding it to the cost of peaches gives us the total cost; this means f(x) represents the total cost.

A fruit company sells two types of boxes large and small. A delivery of two large boxes and three small boxes has a total weight
lara31 [8.8K]

Answer:

the large box weight is 6.50 kg and the small box weight is 13.75 kg

Step-by-step explanation:

The computation of each type of box weight is as follows:

Let us assume the large box be x

And, the small box be y

So,

2x + 3y = 47.......(i)

6x + 5y = 115........(ii)

Multiply by 3 in equation 1

6x + 9y = 141

6x + 5y = 115

Now subtract the last equation from the above one

4y = 26

y = 6.50

For x, it would be

2x+ 3(6.50) = 47

2x + 19.5 = 47

2x = 47 - 19.50

2x = 27.50

x = 13.75

Hence, the large box weight is 6.50 kg and the small box weight is 13.75 kg
