PLS HELP ASAP A herd of dinosaurs made paintings in the sand with their claws.
Each baby dinosaur made 15 paintings and each adult dinosaur made 7 paintings. The entire herd made 208 paintings in total, and there were 3 times as many baby dinosaurs as adult dinosaurs.
How many baby dinosaurs and adult dinosaurs were there?
There were baby dinosaurs and adult dinosaurs.

Step-by-step explanation:

4 adult dinosaurs

12 baby dinosaurs

Step-by-step explanation:

Hi,

Let the number of baby dinosaurs be 'x'

Let the number of adult dinosaurs be 'y'

Given that there are 3 times as many baby dinosaurs as adult dinosaurs

=> x = 3y

Each baby dinosaur made 15 paintings,

=> Total number of paintings baby dinosaurs have made = 15x

Each adult dinosaur made 7 paintings,

=> Total number of paintings adult dinosaurs have made = 7y

Also, given total number of paintings = 208

=> 15x + 7y = 208

=>15*3y + 7y  = 208

=> 52y = 208

=> y = 4

and x = 12.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
