Answer:
<em>The three options that should be chosen are: B, D, E</em>
Step-by-step explanation:
We are given the ratio 5:2 and are required to find 3 equivalent ratios from the provided list.
To find which of the ratios of the list are equivalent to 5:2, we have to simplify them by dividing by a common number.
A 2:5 This ratio is already simplified and it's not equivalent to 5:2
B 10:4. Dividing both numbers by 2 we get 5:2. This option is correct
C 20:50 Dividing by 10 we get 2:5 and it's not equivalent to 5:2
D 35:14 Dividing both numbers by 7 we get 5:2. This option is correct
E 55:22 Dividing both numbers by 11 we get 5:2. This option is correct
Thus, the three options that should be chosen are: B, D, E

Answer:
b = 40
Step-by-step explanation:
A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair.
This situation can be described by an equation of the form y=mx+b , where
x = the time in hours
y = the cost in dollars.
What is the value of b in this equation?
A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair
Writing the above in an equation =
y = $70 × x + $40
y = 70x + 40
Therefore, the value of b in the expression = 40
