Krutika was thinking of a number. Krutika adds 5.4 to the number, then
doubles the result to get an answer of 4.
Form an equation with x from the
information.

n = -3.4

Step-by-step explanation:

( n + 5.4 ) x 2 = 4

( -3.4 + 5.4 ) x 2 = 4

2 x 2 = 4

4 = 4

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
