HELP PLS WILL GIVE BRAINLISTE

A. $725.95

Step-by-step explanation:

First you need to add 129.95 * 5 since they bought 5 plus the delivery cost.

For the first one, the total cost will be:

The cost for the pallets + the cost of delivery.

We know each pallet costs $129.95, thus 5 pallets will cost:

5 * 129.95 = 649.75

$649.75

Adding the delivery of $76.20:

649.75 + 76.20 = 725.95

$725.95

the total cost is $725.95

For the 2nd one, we have two sides that are equal. 3 squares with the value of x, plus 6 circles each with a value of 1, is the same as 9 circles each with a value of 1.

The total value of the circles on the left is equal to 6, and the total value of the circles on the right is 9. We can say the following:

x + x + x + 6 = 9

If we subtract 6 from both sides, since 6-6 = 0 and 9-6 = 3...

x + x + x = 3

Now we can easily see that the value of x must be 1, as:

1 + 1 + 1 = 3

x = 1
