Mr. Nguyen bought a package of 4 chicken legs and a package of 6 chicken wings. Ms. Dawen bought a package of 3 chicken legs and a package of 6 chicken wings. Mr. Nguyen bought 52 ounces of chicken. Ms. Dawen bought 45 ounces of chicken. How much did each chicken leg and each chicken wing weigh?

weight of legs - 7 ounces

weight of wings - 4 ounces

Step-by-step explanation:

Let the weight of a chicken leg be represented by l

Let the weight of a chicken wing be represented by w

The total weight of Mr. Nguyen's package can be represented by this equation :

4l + 6w = 52

The total weight of Ms. Dawen's package can be represented by this equation :

3l + 6w = 45

To find the weight of the legs and wing, use simultaneous equation

4l + 6w = 52 eqn 1

3l + 6w = 45 eqn 2

Subtract equation 2 from 1

l = 7 ounces

Substitute for l in equation 1

4(7) + 6w = 52

28 + 6w = 52

Solve for w

w = 4 ounces

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
