Answer:

205

Step-by-step explanation:

Were gonna start by writing an equation (121+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 205. Hope this helps.

One third of a number x is equal to 22 less the number. Write and solve an equation to find the number
notsponge [240]
In these types of questions the term "of" refers to multiplication. So 1/3 of X is X  times 1/3 which is X/3. 22 less than X means X-22.

SO the equation here is X/3 = X-33, now we solve for X.

multiply both sides by 3 ---> X=3X-99
add 99 on both sides ---> X+99=3X
Subtract X on both sides ---> 99=2x
divide 2 on both sides ---> X=49.5

The system of equations y=3x+1/2 and y=1/5x-1 4/5 is shown on the graph below
Alborosie

Answer:

The first answer in your list of possible options: (0.7, -1.7)

Step-by-step explanation:

Notice that the crossing of the two lines takes place in the fourth quadrant, therefore since the solution to the system is the point where both lines intersect, the solution should have a positive x-value, and a negative y-value to belong to the fourth quadrant.

Then, we need to look at the tick mark labels for the horizontal and vertical axes. based on such, realize that the x value needs to be between the values 0.5 and 1, while the y-value needs to be between -1.5 and -2.

Therefore, (0.7, -1.7) is the closer value one can find from the graph.
