44. $4\frac{9}{10}$

45. 8

Step-by-step explanation:

43. 0.45% = .0045

$= \frac{.0045}{100}$

44. $\frac{1}{2}$ • $9\frac{4}{5}$

= $4\frac{9}{10}$

A square has a perimeter given by the expression 16x+32y. Write an expression for the length of one side of the square.

Lemur [1.5K]

A square has 4 equal sides which make up the perimeter.

Therefore the length of one side = (16x + 32y) / 4 = 4x + 8y Answer

One week Chuck bought 2 packs of chicken and 3 packs of beef for $42.50. The next week he bought 5 packs of chicken and 6 packs

Answer:

Each pack of chicken costs $8 and each pack of beef costs $9.24.

Step-by-step explanation:

This question can be solved using a system of equations:

I am going to say that:

x is the cost of each pack of chicken.

y is the cost of each pack of beef.

2 packs of chicken and 3 packs of beef for $42.50.

This means that $2x + 3y = 42.50$

5 packs of chicken and 6 packs of beef for $94.25.

This means that $5x + 6y = 94.25$

We have to solve the following system:

$2x + 3y = 42.50$

$5x + 6y = 94.25$

I will use the addition method, multiplying the first equation by -2, and adding to the second

$-4x - 6y = -85$

$5x + 6y = 94.25$

-4x + 5x - 6y + 6y = -85 + 94.24

x = 9.24.

And

$2x + 3y = 42.50$

$3y = 42.50 - 2x$

$y = \frac{42.50 - 2*9.24}{3}$

$y = 8$

Each pack of chicken costs $8 and each pack of beef costs $9.24.
