Answer:
x = 4.9
Step-by-step explanation:
We can use the intersecting chords formula:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
7*7 = 10x
49 = 10x
Divide each side by 10
49/10=10x/10
4.9 = x
Answer:
3
Step-by-step explanation:
substitute -2 in where y is.
the subtraction sign in front of the 3 makes it negative so -3 x -2 is positive 6.
4x+6=18, subtract 6 on both sides.
4x=12
divide 4 on each side.

First, simplify brackets. / Your problem should look like: 2.5 ×

× 7 ×
Second, simplify. / Your problem should look like: 17.5 ×

Third, simplify exponent. / Your problem should look like: 17.5 ×

Answer: B
$492.03
the price is already discounted, so then you just multiply 546.7*.10 and that equals 54.67
subtract 54.67 from 546.7
the total is now 492.03
58 divide 10= 5 remainder 8
