Let c represent the number of children Mama has. The number of notebooks she has is
.. 13c +8 = 15c
.. 8 = 2c
.. c = 8/2 = 4
Mama has 4 children and 60 notebooks.
Answer:
x = 8
Step-by-step explanation:
add all side lengths to find the perimeter
5x + 6x + 5 + 6x +3 = 144 add like terms
17x + 8 = 144 subtract 8 from both sides
17x = 136 divide both sides by 17
x = 8 to find the side lenghts replace x with 8 in each expression
-2
Explanation:
You divide by -3each time
54/-3 = -18
-18/-3 = 6
6/-3 = -2
