(-5/6x+51/2)-(2/3x+4)
stiv31 [10]

Answer:

-1.5x + 21.5 (or (43-3x)/2)

Step-by-step explanation:

(-5/6x + 51/2) - (2/3x + 4)

<em>First, find the opposite of 2/3x + 4 because of the negative sign.</em>

-5/6x + 51/2 - 4/6x - 4

<em>Now combine -5/6x and -4/6x to get -9/6x or -3/2x</em>

-3/2x + 51/2 - 4

<em>Convert 4 into 8/2 since 51/2 is a fraction.</em>

-3/2x + 51/2 - 8/2

<em>Since the denominators of 51/2 and -8/2 are the same, just subtract 51 and 8 to get 43.</em>

-3/2x + 43/2

<em>-3/2x and 43/2 have the same denominator (2), so you can just put it like this (It's up to you!):</em>

(43-3x)/2

The answer to (-5/6 + 51/2) - (2/3x + 4) is -3/2x + 43/2 (or (43-3x)/2)

<em>Or you could put it like this (I converted both -3/2 and 43/2 to a decimal.)</em>

-1.5x + 21.5

The coordinate pairs (-5, -11), (0, -1), and (5, 9) are solutions to which function?
Talja [164]
So, the slope is 2 for each of the points. Now, you plug it into y=mx+bSo, you get, y=2x+b
To find b, you choose any pair of x and y values.-5=-22+bb=17

Answer:

the answer would be x=6

to find it you would set 3x-2 equal to 2x+4 and solve because the two sides would be equal if the triangles are congruent

hope this helps :)

0.15(y-0.2)=2-0.5(1-y)<br><br> The answer is -153/35 I just need to know how to get that
butalik [34]

Answer:

y=-\dfrac{153}{35}.

Step-by-step explanation:

The given equation is

0.15(y-0.2)=2-0.5(1-y)

Using distributive property, we get

0.15(y)+0.15(-0.2)=2-0.5(1)-0.5(-y)

0.15y-0.03=2-0.5+0.5y

0.15y-0.03=1.5+0.5y

Isolate variable terms.

0.15y-0.5y=1.5+0.03

-0.35y=1.53

Divide both sides by -0.35.

y=\dfrac{1.53}{-0.35}

y=-\dfrac{1.53}{0.35}\times \dfrac{100}{100}

y=-\dfrac{153}{35}

Therefore, y=-\dfrac{153}{35}.
