Answer:
Each boy will get <u>25</u> marbles.
Step-by-step explanation:
Given:
William has 3 jars of marbles to share equally with his brother the first jar holds 12 marbles the second jar holds 21 marbles the last jar holds 17 marbles.
Now, to write an expression using parentheses to find number of marbles each boy get.
Let the number of marbles each boy get be 
Total number of boys = 2.
Number of marbles first jar holds = 12.
Second jar holds = 21.
And third jar holds = 17.
As given, William shares marbles equally with his brother.
Now, we write the expression to find the number of marbles each boy get:




Therefore, each boy will get 25 marbles.
We can write this in algebraic terms as:
16+8x = 24+6x
so
2x = 8
x = 4
The number is 4.
Answer:
Step-by-step explanation:
one angle is 80
let other angle be 'x'
then third angle will also be equal to x. (given)
using angle sum property,
x + x + 80 = 180. (1)
2x=100
x=50. (2)
therefore all angles are 80,50,50
