So basically you need to multiply 3000x4000 in two ways? If so you can use basic multiplication and an area model
S=d/t
45=29/t
t=45/29
convert to min
t=45/29 *60=38.66min
Answer:
x1 = -4; x2 = 10
Step-by-step explanation:
1) Expand the module as two separate equations:
x - 3 = 7
x - 3 = -7
2) Solve the equations:
x = 10
x = -4
=> x1 = -4; x2 = 10
