Step-by-step explanation:
(1$) 7+ ($5) 4 + ($10) 11=22 bills
7+20+110=137$
For this case we have the following system of equations:
We must solve the system by the method of elimination. To do this we multiply the second equation by -3, then:
We add both equations:
We find the value of "x":
Thus, the solution of the system is:
We verify:
Is fulfilled!
Is fulfilled!
Answer:
It can't be a triangle in the first place, because the measures don't add up. 40 + 60 + 100 = 200, but triangles are supposed to be 180 degrees. So it isn't even a triangle.
If this helped please mark Brainliest.
2(z - 5) + (z - 8) =
= 2z - 10 + z - 8 =
= 2z + z - 10 - 8 = <u>3</u><u>z</u><u> </u><u>-</u><u> </u><u>1</u><u>8</u> ← the end
The mode, if I recall correctly. The mode is simply the amount of numbers repeated, and has nothing to do with the calculations.
