mina [271]

Answer:

2x = 20 meters

Step-by-step explanation:

Let the distance between each seedling be "x"

Therefore the distance between the 3rd and the 5th seedling will be 2x

Hence if the total distance between the first and last seedling was 100 meters and 10 seedlings was planting, distance between each seedling will be =

TEA [102]

Answer:

Laura will have exactly $72.00 after purchasing the bicycle.

Step-by-step explanation:

We are given that Laura ends $115 per month of babysitting.

We also learn that she wants to save her money from June and July, which means she wants to save her money over a period of two months.

Therefore, she will earn $115 twice.

\displaystyle{\$115 \times 2 = \$230}

Then, she wants to purchase a bicycle that costs $158, so we need to subtract the cost of the bicycle from her total earnings.

\$230 - \$158 = \$72

Therefore, Laura will have exactly $72.00 remaining after her purchase.
