Pablo and Johanna have to do a yearlong study for their biology course. After some discussion, they decide to try comparing thei

Response:

69

Detailed steps:

To calculate the total score for all tests, you take 93 and multiply it by 7 to get 651. Then, multiplying 90 by 8 results in 720. Subtracting 651 from 720 gives you 69.

Answer:

girls = 90

boys = 125

adults = 20

Detailed explanation:

Total attendees at the summer camp = 235

Let

girls = x

boys = x + 35

adults = x - 70

Total attendees = girls + boys + adults

235 = x + (x + 35) + (x - 70)

235 = x + x + 35 + x - 70

235 = 3x - 35

Add 35 to each side

235 + 35 = 3x

270 = 3x

Divide both sides by 3

x = 270/3

= 90

x = 90

girls = x = 90

boys = x + 35

= 90 + 35

= 125

adults = x - 70

= 90 - 70

= 20

Total = 90 + 125 + 20

= 235

Answer: It’s two trees

Step-by-step explanation:

Given that the city plants a tree every 20 feet along Dayton Avenue, we first need to establish the length of the side that faces Dayton Avenue.

We currently have three sides unaccounted for. However, it’s crucial to note that the side next to Dayton Avenue has the same length as the two unaccounted sides combined. This equivalence holds because both lengths include the 1 feather and 2 feather markers, confirming congruence.

Thus, the sum of both side lengths will be .

Consequently, the side next to Dayton Avenue measures

feet.

Having determined that this side is 57 feet long, we divide this length by 20 to find the tree planting intervals. Since the planting occurs only in complete 20-foot segments, if the division results in a decimal, we must round down. A tree is only planted if complete segments of 20 feet are reached.

This rounding process gives us 2.

I hope this clarifies!
