Answer:
63.69
Step-by-step explanation:
Y=18 is the correct answer
Answer:
x = 13
Step-by-step explanation:
ΔRST≈ΔYSZ
therefore:
RT/ST = YZ/SZ
(3x-7)/40 = (2x+2)/35
cross-multiply:
40(2x+2) = 35(3x-7)
80x+80 = 105x-245
80 = 25x-245
325 = 25x
325/25 = x
x = 13
On the number line after 10 moves frog is at the integer -96.
Given that, a frog starts at 0 on a number line.
It jumps 100 units to the right then jumps 200 units to the left=+100-200=-100 (2 moves).
It then jumps 199 units to the right followed by 198 units to the left =-100+199-198=-99 (2 moves).
It then jumps 197 units to the right followed by 196 units to the left =-99+197-196=-98 (2 moves).
It then jumps 195 units to the right followed by 194 units to the left =-98+195-194=-97 (2 moves).
It then jumps 193 units to the right followed by 192 units to the left =-97+193-192=-96 (2 moves).
Hence, on the number line after 10 moves frog is at the integer -96.
