Answer:
3000
Step-by-step explanation:
If they spend 60% of their income, they save 40% of their income
Let x be their income
x * 40 % = 1200
.40x = 1200
Divide each side by .4
x = 1200/.4
x =3000
Answer:
177 and 178
Step-by-step explanation:
First, the expression for the 2nd mile marker is x+1.
Now, you add x and x + 1 together to get 2x + 1
Next, make 2x + 1 equal to 355
Now subtract 1 and then divide by two on both sides to get x = 177.
This means that the first mile marker is 177 and the next is 178.
Since 30 is not a square root you would use the closest square roots √25 and √36 which makes your answer 5 and 6
