Answer:
2.5x
Step-by-step explanation:
The expression is saying multiplying 2.5 and a variable.
2x + 3y = -21
2x = -21 - 3y
x = -10.5 - 3/2y
-10x + 2y = 20
-10(-10.5 - 3/2y) + 2y = 20
105 + 15y + 2y = 20
105 + 17y = 20
17y = -85
y = -5
2x + 3y = -21
2x + 3(-5) = -21
2x - 15 = -21
2x = -6
x = -3
Therefore, the coordinates are (-3, -5).
Answer:
142
Step-by-step explanation:
Ok explanation
we know the sides 9, 11, 38, and 13.
there are 2 missing sides we need to find
so the first one whic is the longer one is we know that the 38 is already 1 part of it but not the whole thing. We know the 9 is part of the 38 since it connects. So that gives us that side of 47.
Now for the shrter side, we know 1 part of it is 13 And the other part is 11. So we Add them up and get 24
Now the sides are 9, 11, 38, 13, 47, and 24
We add them up and get 142
I think to turn 193% to decimal is you have to divide it by 100.
193/100= 1.93
When you write it as a fraction 93/100 (there are two decimal number, so it would be over a hundred) and simplify it. You have to remember that you have a whole number and just add it to the fraction.
Hope that this will help you.
