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 $5x + 10y\geq\$70 \ and \ x + y \leq 10 hours$

If x=2y=3z then x:y:z equals what?

Alisiya [41]

Answer: x=6 y=3 z=2

Step-by-step explanation: The question is very vast so im guessing that its just finding 3 whole numbers that can equal the same ammount being multipied by 2 and 3. I chose 6. But theres many others. The answer should be correct because if we replace the letters with the numbers i put in the answer it should look like this: 6=2•3=3•2

When we do simplify this we should get 6=6=6 which is true.

Again you can use different numbers for example 12 as X. Then you need to divide 12 by whats behind the Y. So 12÷2 is 6. So Y is equal to 6. To find Z all you need to do is follow the same steps as Y. Find the number behind Z (3) and divide that into 12. So it would be 12÷3. And if you do the math right it should look like this: X=12, Y=6, Z= 4. And when you imput the numbers to thier corresponding letter it should look like this 12=2(6)=3(4) which simplified looks like 12=12=12 which is true.
