Excessive returning of items
Answer:
a=3, c=-4, x=8
Step-by-step explanation:
5=4a-7
4a-7=5
4a=5+7
=12
a=12÷4
=3
3-8c=35
-8c=35-3
=32
c=-32÷8
=-4
-1/2x-7=-11
-1/2x=-11+7
=-4
x=4÷1/2
=4/1×2/1
=8
the SAS similarity theorem
The volume of one tissue box is 170 cubic inches, so the volume of 25 tissue boxes are 4250 cubic inches.
remove parenthesis : 2/3 - 5/6 + 9/4 - 3/5
add fractions based on lcm : 40/60 - 50/60 + 135/60 - 36/60
equal denominator so combine fractions : 40 - 50 + 135 - 36 / 60
add/subtract : 40 - 50 + 135 - 36 = 89
answer ; 89/60
