Step-by-step explanation:

Putting value of y

2x + x - 5 = 10

3x - 5 = 10

3x = 10 + 5

3x = 15

x = 15/3 = 5

Putting value of x

Y = x - 5

Y = 5 - 5

Y = 0

Devon babysits x hours a week after school for 5$ an hour, and also has a job as a cashier y hours a week for $10 an hour. He wa

Papessa [141]

Answer:

The inequality expression are $5x + 10y\geq\$70 \ and \ x + y \leq 10 hours$

Step-by-step explanation:

Given:

Number of hours for babysitting for a week = $x \ hours$

Charge for baby sitting = 5$ an hour

Money earned for babysitting in x hours = $5x$

Number of hours for cashier for a week = $y \ hours$

Charge for Cashier = $10 an hour

Money earned for Cashier in y hours = $10y$

He wants to earn at least 70$.

Hence the expression becomes.

$5x + 10y \geq 70 \$$

Also,

He can’t work any more than 10 hours a week

Hence the expression becomes.

$x + y < 10 \ hours$

Inequality equation for the given statements are:

The inequality expression are $5x + 10y\geq\$70 \ and \ x + y \leq 10 hours$

Is .65 greater than .437

Aleksandr [31]

Yes! In decimals, it is based on the first number. If it is the same number, it is based on the second number. This trend continues unless it is a repeating decimal, where you are forced to round it.

0.65
0.437

6 > 4 so it is greater, yes.

Simplify:<br>1/1-x^(b-a)+1/1-x^(a-b)

Pachacha [2.7K]

Answer:

Step-by-step explanation:

simplify:

1/1-x^(b-a)+1/1-x^(a-b)

$\frac{1}{1-x^{b-a}} + \frac{1}{1-x^{a-b}}\\= \frac{1-x^{a-b} + 1-x^{b-a}}{(1-x^{b-a})(1-x^{a-b})}\\= \frac{1-x^{a-b} + 1-x^{b-a}}{(1-x^{b-a}-x^{a-b}+x^{b-a+a-b})}\\= \frac{1-x^{a-b} + 1-x^{b-a}}{(1-x^{b-a}-x^{a-b}+1)}\\= \frac{2-x^{a-b}-x^{b-a}}{2-x^{b-a}-x^{a-b}}\\= 1\\ \\$

Hence the required answer is 1
