Help me 3x+1/10=x-1/7 ok so I understand that I'm supposed to cross multiply so 1 x 10=10 7x3=21 so now do i do 21x-7? please He
koban [17]

Simplify both sides of the equation

3x+1/10 = x+ -1/7

Subtract x from both sides

3x+1/10 -x = x+ -1/7 -x

2x+1/10 = -1/7

Subtract 1/10 from both sides

2x+1/10 - 1/10 = -1/7 -1/10

2x= -17/70

Divide both sides by 2

2x/2 = -17/70/2

x= -17/140

decimal x will equal -0.121

Function question<br><br>read the graph then solve
viktelen [127]

Answer:

  1. g(5x) = 0
  2. x = -10

Step-by-step explanation:

Do what your instructions say: read the graph and solve.

1. In order to find x, you look for the point where g(x) is 4. That point is found where x = -2. (See the first attachment.)

Then 5x = 5·(-2) = -10. To answer the question, you need to find the value of g(-10). Look where the graph crosses the vertical line at x=-10. It is at y=0, so ...

... g(5x) = g(-10) = 0

2. You already found the answer to this when looking for the answer to the first question. g(x) = 0 when x = -10. (See the second attachment.)

NEED HELP ASAP!!!
Sergeeva-Olga [200]

Answer:

(b) P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}

Step-by-step explanation:

Let E: Event of getting a 3 in the spinner.

So, the number of favorable outcomes  =  11

Total number of outcomes = Number of times the outcomes is {1,2,3,4,5,6}

= {13 +10 +11+16+11}  = { 61}

So, the total number of outcomes = 61

\textrm{Probability of Event E}  = \frac{\textrm{Number of favorable events}}{\textrm{Total number of outcomes}}

So, here P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}

Prove that ax+by+c=0 represent the eqn of straight line
ivann1987 [24]
If we rewrite it as y=mx+d (which can be taken from here from subtracting ax and c from both sides, then dividing b, resulting in y=(-a/b)(x)-c/b. We can then substitute -a/b for m and -c/b for d), if d=0, then we have m as a constant and as we add a specific number to y (that number being m) every time the x value increases by 1, it therefore forms a straight line. If d is not 0, then we simply add d to every single number - this is still a straight line due to that we still add a specific number to y every time x increases by 1 every single time

Solve the equation x/2=x/3+1/2​
Mice21 [21]

Answer: x=3

Step-by-step explanation:

Move all x terms to the same side- x/2-x/3-1/2

Multiply to get common denominator- 3x/6-2x/6=1/2

Subtract 3x/6 and 2x/6 - x/6=1/2

Simplify - x=3
