Answer:
8m^2n−15mn^2
Step-by-step explanation:
(6m^2n+2m^2n)+(−14mn^2−mn^2)
= 8m^2n−15mn^2
Answer:
-4
Step-by-step explanation:
3+1 = 4 so just put a dash at the start and you ger -4
Make 2 eqn, let a be apples and o be oranges:
1. 5a + 4o = 10
2. 5a + 5o = 11
set up an elimination:
1. minus 2.
5a + 4o = 10
- 5a + 5o = 11
____________
o = 1
sub “o” into one of the eqn
5a + 5(1) = 11
5a = 11-5
5a = 6
a = 6/5
a = 1.2
therefore, an orange costs $1.00 and an apple costs $1.20
Answer:
7
Step-by-step explanation:
1/7+1/3= 3/21+7/21= 10/21= 0.476190
the 6 digits after the decimal point get repeated
6*3= 18- three full cycles and the second digit after 3 cycles = 7 so the 20th digit is 7
It may be a negative or a fracton of a number.
