Answer: Choice A) Distributive property
We're multiplying the outer -3 with the inner x to get -3x
Also, multiply the outer -3 with the inner +4 to get -12
So that's why -3(x+4) = -3x-12
Answer:
x=3y
Step-by-step explanation:
ATQ
(x+y):(x-y)=2
or, x+y=2x-2y (crossmultiply)
or, 0= 2x-x-2y-y
or, x- 3y=0
or, x=3y is required equation
Answer:
2.25
Step-by-step explanation:
In this question, we are asked to calculate the number of slices to be eaten by a man who has restrictions on his diet.
Firstly, as we can see, he bought 3 which weighs a total of 1/3 pounds. The weight of one of this would be 1/3 divided by 3 = 1/9 pounds
Now to stay true to his weight by not exceeding 1/4, we need to know how many of the 1/9 can he eat. To solve this, we directly divide 1/9 by 1/4 = 1/4 divided by 1/9 = 2.25
Answer:
D. 6x-14
Step-by-step explanation:
So first we would do 3x^2+3x^2-5x^2
That would all cancel out so that would be 0.
Next we would do 3x-4x+7x, this would equal to 6x
Finally we would do -4-8-2, this would be equal to -14
Then the equation would be 6x-14
All you have to do is combine like terms.
Hope this helped!
