Hello!
There is 28 students in 4 equal groups. 28 ÷ 4 = 7, so there is 7 kids in each group. She gave each group 35 sheets of paper, so 35 x 4 = 140. 35 <span>÷ 7 = 5. Each student in one group got 5 sheets and everyone in total got 140 sheets.
Enjoy.

Answer: I did it in the explanation thingy-
Step-by-step explanation:
Step 1. 8792 - 6886 = 1906
Step 2. 12 x 9 108
That... OR the answer is 205848X
Answer:
Step-by-step explanation:
in google you will get the answer very quickly
Answer:
Yes
Step-by-step explanation:
using distributive properties,
(3x+1)(4x-5) = 3x(4x-5) + 1(4x-5)
=> 12x^2 - 15x +4x - 5
=> 12x^2 - 11x - 5
First let's find the angles a and b.
We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.
cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.
We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.
