Answer:
A
Step-by-step explanation:
The common difference d in an arithmetic sequence is
a₂ - a₁ = a₃ - a₂ , substitute values
4y + 1 - (y + 3) = 8y - 3 - (4y + 1) ← distribute both sides and simplify
4y + 1 - y - 3 = 8y - 3 - 4y - 1
3y - 2 = 4y - 4 ( subtract 3y from both sides )
- 2 = y - 4 ( add 4 to both sides )
2 = y → A
Answer:
180.
Step-by-step explanation: Divide 5 and the $60 and it would give you 12 . So we know that each pizza cost $12, so multiply the 15 pizzas and the 12 dollars. Thus the answer, 180 . Hope this helped lol.
Answer:
1 - 2 exponent 4
2 - 3 exponent 2
A - 5 exponent 2
I don't understand 3
Step-by-step explanation:
2.
The 21 degree angle shown is a corresponding angle to angle 3, which means they are identical, so angle 3 is 21 degrees.
Angle 3 and 4 are supplementary angles which need to add up to 180 degrees.
Angle 4 = 180 - 21 = 159 degrees.
3. A bisector means both sides are the same length.
Set the two equations to equal to solve for x:
4x+12 = 2x +18
Subtract 2x from both sides:
2x +12 = 18
Subtract 12 from both sides:
2x = 6
Divide both sides by 2:
x = 3
Now you have x, solve both equations and add them together:
4(3) +12 = 12+12 = 24
2(3) +18 = 6+18 = 24
24 +24 = 48
AB = 48
