Answer:
Step-by-step explanation:
Statements Reasons
1). ∠CXY ≅ ∠BXY 1). Given
2). ∠CAX ≅ ∠BAX 2). Given
3). AC ≅ AB 3). Given
4). AX ≅ AX 4). Reflexive property
5). ΔAXC ≅ ΔAXB 5). SAS property of congruence
6). CX ≅ BX 6). CPCTC
7). XY ≅ XY 7). Reflexive property
8). ΔYXB ≅ ΔYXC 8). SAS property of congruence
9). ∠XCY ≅ ∠XBY 9). CPCTC
X+7.5=21.5
Subtract 7.5 from both sides
X=14 which is C
hope this helps good luck have a nice day
Answer:
an = 5n -7
Step-by-step explanation:
Try the offered formulas with n= 1 and see which gives you the first term of the sequence.
<u>an = -2n +3</u>
-2(1) +3 = 1 . . . . not -2
<u>an = -2n +7</u>
-2(1) +7 = 5 . . . . not -2
<u>an = 5n +3</u>
5(1) +3 = 8 . . . . not -2
<u>an = 5n -7</u>
5(1) -7 = -2 . . . . this is the formula you want
_____
If you recognize the common difference of the sequence to be 5, then you can automatically eliminate any formulas that don't contain 5n.
First, we need to calculate the amount of ribbon in inches, and then convert it into feet.
Since 30 inches of ribbon is used in one bow, to make 10 bows, we need multiply:
30 x 10 = 300
Now, we need to convert the inches to feet.
300 in = 25 ft
Our answer is 25 ft of ribbon.
Hope this helped!
