Nuetrik [128]

Answer:

1047 m = c

Step-by-step explanation:

Given : Mr.kelly pays $12,564 a year for rent. His rent is a constant amount each month.

To Find:Which equation represents the amount he pays her month if m=months and c=total rent paid for the year?

Solution :

Since he pays for a year (12 months) = $12,564

Since His rent is a constant amount each month.

He pays for one month = $\frac{12564}{12}=1047$

Thus the amount he pays per month $1047

If he pays for m months then the total amount(c) of rent for m months

⇒1047 m = c

Hence equation represents the amount he pays her month if m=months and c=total rent paid for the year: 1047 m = c

The number is three digits, the number is even, the tens digit is half the hundreds digit, the sum of the digit is 14 what is th

ser-zykov [4K]

Let x represent the digit in the hundreds place, y represent the digit in the tens place, and z represent the digit in the ones place. What do we know about each digit?

x: twice y (2, 4, 6, or 8)

y: half of x (1, 2, 3, or 4)

z: an even number (0, 2, 4, 6, or 8).

The sume of the digits is 14. So, x + y + z = 14

Choose one of the digits and look at your options (if any).

when x=2, then y = 1, which means z has to be 11 (NOT VALID)

when x=4, then y = 2, which means z has to be 8 (428 works!)

For fun, let's see if any other numbers work:

when x=6, then y = 3, which means z has to be 5 (NOT VALID)

when x=8, then y = 4, which means z has to be 2 (842 works!)

Answer: 428 and 842 both work
