Answer:
Multiplying by 1 does not change the ratio
Step-by-step explanation:
Multiplying a/b by c/c gives the equivalent ratio (ac)/(bc) because c/c is 1, the multiplicative identity element. Multiplying by 1 does not change the ratio.
On the left side use distributive property:
3(n) + (3)(4) = -6 + 15n
3n + 12 = -6 + 15n
Subtract 3n:
12 = -6 + 12n
Add 6:
18 = 12n
Divide 12:
18/12 = n
You can simplify it further:
n = 3/2 or 1.5
Answer:
Just the hypotenuse and the 2 legs
Answer:
X= -4/3
Step-by-step explanation:
Answer:
y = -1/2x + 7/2
Step-by-step explanation:
y = -1/2x + b
3 = -1/2(1) + b
3 = -1/2 + b
7/2 = b
y = -1/2x + 7/2
