Kate bought 5 pounds of hamburger and 2 pounds of hotdogs and paid $28.50. Eric bought half the amount of hamburger and a fourth of the amount of hotdogs that Kate did and paid $12.50. Find the cost per pound of hamburgers and hotdogs.

This is a system of equations

Answers

Answer:

hamburgers - $4.30 hotdogs- $3.50

The required cost of a hamburger and a hotdog is $4.3 and $3.5 respectively.

What are simultaneous linear equations?

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

here,
Let the cost of the hamburger be x and the cost of hotdogs be y.
According to the quesiton,

5x + 2y = 28.50 - - - - (1)
5x /2 + 2y / 4 = 12.50
10x + 2y = 50 - - - -(2)
From equation 1 and 2
5x = 21.5
X = $4.3
Now,
5×4.3 + 2y = 28.50
y = 7 / 2
y = $3.5

Thus, the required cost of hamburgers and hotdogs is $4.3 and $3.5 respectively.

Solve for h.
h - 6 =

7

Answers

Answer:

h = 13

Step-by-step explanation:

Solve for h.

h - 6 =  7

h = 7 + 6

h = 13

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

check

13 - 6 = 7

7 = 7

the answer is good

So, this one is pretty easy. Since h-6=7, you just add 6 and 7 and subtract 6 to find the answer, like this.

6+7=13

13-6=7

and h=13

Answer:

x = 32

Step 1: Solve the right-hand side of the equation.

47 - x = 50 - 35

=> 47 - x = 15

Step 2: Subtract '47' from both ends.

=> 47 - x = 15

=> -x = 15 - 47

Step 3: Solve for x.

=> -x = -32

=> x = 32.

Larry needs 45 ounces of graph juice for 6 guests. Later, he finds out that 26 guests are coming. how much graph juice does he need to purchase?

A. 196 Ounces

B. 270 Ounces

C. 40.3 Ounces

D. 1170 Ounces

Answers

Based on the amount of juice needed for 6 guests, the amount of juice Larry will need for 26 guests is A. 196 ounces.

First find out the amount of juice a single guest will need:

= Quantity of juice / Number of guests

= 45 / 6

= 7.5 ounces

If a guest needs 7.5 ounces, 26 guests would need:

= 25 x 7.5

= 195 ounces

In conclusion, 196 ounces of juice is needed.
