Donna bought 5 bags of dog treats for $11.65. what is the cost per bag of dog treats?

$2.33

Step-by-step explanation: In this problem, we want to find the unit price for 1 bag of dog treats.

Unit price means the cost per unit. In this case, the cost per bag of dog treats. Since we know that it costs $11.65 for 5 bags of dog treats, to find the cost for 1 bag of dog treats, we need to divide 5 into $11.65.

*I have attached my long division in the image provided.*

So 5 divides into 11.65 2.33 times which means that each bag of dog treats will cost $2.33 so the unit price is $2.33.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
