Answer:
When subtracting expressions, we are applying the distributive property, where a multiple of an expression in brackets is applied to to each term.
e.g.
a(x + y) = ax + ay
In the case of subtracting an expression, we're doing the same thing, but in the example above, "a" would be equal to -1.
(a + b) - (c + d) ≡ (a + b) + -1(c + d)
And so the negative one is distributed across the terms within the brackets.
Answer:
6
Step-by-step explanation:
Since 3/4 has a different denominator then 1/8 we can multiply 3/4 by 2 to get 6/8 which has the same denominator. Now we just divide the numerators and denominators by each other to get 6.
Answer:
Using graph for units
D=1/2(6)(9)=27 sq units
E=1/2(7)(6)=21 sq units
F=1/2(6)(8)=24 sq units
Step-by-step explanation:
The formula is I=PRT so multiply everything together. Principal = 12,000, R = 5.25%, Time = Years
