Answer:
5(x-y)/6
Step-by-step explanation:
(4x-y)/3 - (x+y)/2
We have to find the Least common multiple to simplify the operation.
(The Least common multiple of 3 and 2 = 3*2 = 6)
[2(4x-y)-3(x+y)]/6
(8x-2y-3x-3y)/6
5x-5y/6
5(x-y)/6
The rule of subtracting the fraction, including the constant, is to do in a simplification method.
Therefore, the answer is 5(x-y)/6
A)Plugging in our initial statement values of y = 16 when x = 10, we get:
16 = 10k
Divide each side by 10 to solve for k:
16/10=
k = 1.6
Solve the second part of the variation equation:
Because we have found our relationship constant k = 1.6, we form our new variation equation:
y = 1.6x
Since we were given that x, we have
y = 1.6()
y = 0
B)Plugging in our initial statement values of y = 1 when x = 15, we get:
1 = 15k
Divide each side by 15 to solve for k:
1/15
=15k
k = 0.066666666666667
Answer:
A, She added before multiplying.
Step-by-step explanation:
First, start off by using GEMDAS.
Grouping
Exponents
Multiply
Divide
Add
Subtract
You work from left to right - so you obviously divide first, which Amanda did successfully. Then, you multiply, which is exactly where Amanda went wrong. She was supposed to multiply before adding the 3 with 4.
Not sure if this made sense,
<span>(3 x 1000) + (16 x 10) + (7 x 1) = 3167. In standard form, this is 3.167 x 10^3. </span>
