Step-by-step explanation:
5x+2y=-11
2x+2y=5
so you find values that match or can multiply by something to match-2
5x+2y=-11
- 2x+2y=5
=3x+0y=-16
3x/3=-16/3
x=5 1/3
then substitute x in one of the equations to get y
Answer:
It can't be answered because it has to have a variable or number after log200 because that's how you get 2.301.
Step-by-step explanation:
Give me the variable or number and I'll answer it from there.
Answer:
1) f
4 * ¼ = 1 (Multiplicative inverse property)
2) c
6 * 1 = 6 (Identity property of multiplication)
3) h
5 + 7 = 7 + 5 (Commutative property of addition)
4) j
If 5 + 1 = 6 and 4 + 2 = 6, then 5 + 1 = 4 + 2 (Transitive property)
5) a
4(x - 3) = 4x - 12 (Distributive property)
6) i
3(5) = 5(3) (Commutative property of multiplication)
7) k
Rules that allow us to take short cuts when solving algebraic problems.(Properties)
8) d
5 * (3 * 2) = (5 * 3) * 2 (Associative property of multiplication)
9) g
4 + (-4) = 0 (Additive inverse property)
10) e
2 + 0 = 2 (Identity property of addition)
11) b
A + (B + C) = (A + B) + C (Associative property of addition)
