Answer:
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

Answer:
x = 9º
∠B = 40º
Step-by-step explanation:
5x-5º = 3x+13º
<em>[add 5 to both sides]</em>
5x = 3x+18º
<em>[subtract 3x from both sides]</em>
2x = 18º
<em>[divide each side by 2]</em>
x = 9º

3x+13º = 3(9º)+13º=27º+13º = 40º
3/2 ÷ 1/4 is 3/2 x 4/1 (the reciprocal)
Since 3/2 is the same as 1 1/2 we are asking how much are 4 x 1 1/2
Think money
1 1/2 is like $1.50
If I had $1.50 two times - I'd have $3.00
If I had $1.50 four times - I'd have twice as much or $6.00
Now I know that 6 is between 5 and 7 so answer c. is correct
You could also just multiply 3/2 x 4/1 but I think my explanation helps you understand it better than just using the multiplication algorithm.
