For each hour he babysit,Anderson earns 1$ more than half of carey's hourly rate.Anderson earns 6$ per hour. wich equation can b

Lena [83]

Answer:

The expression to find Carey's hourly rate is: $c = 2*a - 2$ . Carey's hourly rate is $10.

Step-by-step explanation:

Anderson receives 1 more than half of carey's hourly rate. If we call Anderson's rate by "a" and Carey's by "c", we can express this phrase in the following equation:

$a = \frac{c}{2} + 1$

We want to find the Carey's rate, therefore we need to isolate the "c" variable.

$\frac{c}{2} + 1 = a\\\frac{c}{2} = a - 1\\c = 2*a - 2$

Since Anderson earns $6, then we can find Carey's rate:

$c = 2*6 - 2 = 12 - 2 = 10$

A number

eimsori [14]

Answer:

let the unit digit be x

and the tens digit be y

so x+y = 9 ---> y = 9-x

the number is 10y+x

the number reversed is 10x + y

3(10y+x) = 8(10x + y)

30y + 3x = 80x + 8y

22y = 77x

2y = 7x

2(9-x) = 7x

18 - 2x = 7x

18=9x

x=2

y=7

the number is 72

check:

number is 72

reverse is 27

is 3(72) = 8(27)
