Mathematics
1 answer:
earnstyle [38]3 years ago
8 0

Answer:

b = d/5a + c

Step-by-step explanation:

5a(b-c)=d

Divide by 5a on both sides

(5a/5a)(b-c)=d/5a

b-c = d/(5a)

Add c to each side

b-c+c = d/5a + c

b = d/5a + c

Joe borrowed $5,000 from the bank at a rate of 7% simple interest per year. How much interest did he pay in 7 years?
yaroslaw [1]

Answer:

$2450

Step-by-step explanation:

7% of 5000 is 350 which means that she would be paying $350 a year and so if you multiply the amount she pays a year ($350) you would get $2450.

I hope this helps.

ASAP What is the constant of variation for the quadratic variation? 9y = 4x2
kaheart [24]
If you would like to know what is the constant for the quadratic equation 9 * y = 4 * x^2, you can calculate this using the following steps:

<span>9 * y = 4 * x^2     /9
</span>y = 4 * x^2 / 9
y = 4/9 * x^2

The correct result would be B. 4/9.

For your job, you often fly between Seattle and Miami. The distance between these cities is 2,724 miles. You earn a free flight
Alborosie
So you would multiply 2,724 by two since it is a round trip. Then you would divide 43,000 by that number to get the number.
