What is the value of x in the equation x-2/3 + 1/6 =5/6 ?

Answers

x is a negative one (-1). The negative one makes it so that the -2/3 is a positive when they multiply.

So in this problem we can see that 2 out of 3 of the fractions have a denominator of 6. One of the fractions (2/3) has a denominator of 3. But we can make the denominator 6 by multiplying it by 2!

Now the equation is:

x - 4/6 + 1/6 = 5/6

So now let's solve for x!

x - 4/6 + 1/6 = 5/6

x + 1/6 = 9/6 (Addition property of equality)

x = 8/6 (Subtraction property of equality)

Now we divide...

8 divided by 6 equals 1.33

Now if we plug that into the equation as 1 and 1/3...

1 and 1/3 - 2/3 + 1/6

2/3 + 1/6

4/6 + 1/6 = 5/6

So that means your answer is decimal 1.33 or mixed fraction 1 and 1/3

The answer would be 5(c+2) = 79
5*c= 5c
5*2= 10
5c+10=79

Solve by substitution
3x y=-9
x-2y=-10

Answers

: 3x + y = 9
y = 9 - 3x

x - 2y = 10
y = (x - 10)/2

2(9 - 3x) = x - 10
18 - 6x = x - 10
7x = 28
x = 4

y = 9 - 3(4)
y = 9 - 12
y = - 3

Answer: x = 4, y = - 3

Proof—2nd equation:
4 - 2(- 3) = 10
4 + 6 = 10

HELP What function models the data shown on the graph?

f(x) = 2(x – 5)(x – 1)

f(x) = –2(x – 5)(x – 1)

f(x) = 2(x + 5)(x + 1)

f(x) = –2(x + 5)(x + 1)

Answers

It looks like the parabola are going down, so the coefficient should be negative,
B or C,
then we see that the parabola has x -intercepts (1,0) and (5,0)
these roots should be written as multiples
x=1, so x-1=0
and
x=5, so x-5=0,
so (x-1)(x-5) and negative first coefficient -2 at the same time.
We can see only in the
B. f(x) = –2(x – 5)(x – 1)
