Answer:
Which statement is true about the angles? Answer is measure B is = 60 which is B
Step-by-step explanation:
took the test
Answer:
45
Step-by-step explanation:
we know the number is two digits.
we know that the sum of the digits is 9
therefore, the only possible numebrs are:
18, 81
27, 72
36, 63
45, 54
we also know that the inverse of the digits is the original number plus nine
therefore, 18 and 81 are out
27 and 72 are out
36 and 63 are out
the only numbers left are 45 and 54.
since 45+9=54, the number is 45.
<h2>6.</h2><h3>Given</h3>
<h3>Find</h3>
- The side length of a regular pentagon whose side lengths in inches are represented by these values
<h3>Solution</h3>
Add 27 to get
... 5x = 2x + 21
... 3x = 21 . . . . . . . subtract 2x
... x = 7 . . . . . . . . . divide by 3
Then we can find the expression values to be
... 5x -27 = 2x -6 = 5·7 -27 = 2·7 -6 = 8
The side of the pentagon is 8 inches.
<h2>8.</h2><h3>Given</h3>
- a rectangle's width is 17 inches
- that rectangle's perimeter is 102 inches
<h3>Find</h3>
- the length of the rectangle
<h3>Solution</h3>
Where P, L, and W represent the perimeter, length, and width of a rectangle, respectively, the relation between them is ...
.... P = 2(L+W)
We can divide by 2 and subtract W to find L
... P/2 = L +W
... P/2 -W = L
And we can fill in the given values for perimeter and width ...
... 102/2 -17 = L = 34
The length of the rectangle is 34 inches.
Answer:
yes google has moat of the answers for these
9+-3 means 9 plus 3 less
basically it is 9-3=6
