OK, so to simplify the left hand side, we need to multiply -12 and -5 to get our final exponent for j, therefore we get j^60 = j^t,so t=60 is your answer
Answer:
a. 100 mph
b. 500 mph
Step-by-step explanation:
a.
Let the speed of Lindbergh's plane be x.
Today's planes are 5 times faster, so their speed is 5x.
Today's planes speed is 400 mph faster than Lindbergh's speed.
x + 400 = 5x
5x = x + 400
4x = 400
x = 100
Lindbergh's speed was 100 mph
b. 5x = 5 * 100 = 500
Today's planes fly at 500 mph
Increasing hope that helps
Yes bc when I simplified it I got -2+n but that's just written a different way
The retail price of the basketball shoe is $110 because 37.5% of $80 is $30. So, you add $80 to $30 and you get $110.
