If the unknown number is x then the equation is:
25x/45=-65
Solution
5x/9=65
5x=-65*9
5x=-585
5x/5=-585/5
x=-117
Rounded to the nearest whole number is still 43
It isn't a real test. I do believe it helps you with your grade and the classes you'll take next year.
Answer:
y = 56
Step-by-step explanation:
the midsegment SV is half the length of the side TU , that is
y - 9 =
(y + 38) ← multiply both sides by 2 to clear the fraction
2y - 18 = y + 38 ( subtract y from both sides )
y - 18 = 38 ( add 18 to both sides )
y = 56
