5 times 4 equals 20. that's how
Answer:
B
Step-by-step explanation:
Answer is a. 2
3 - 2x= -7
- 2x = -4
x = 2
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:
the answer to that is -18x^2
