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

Find the unknown angle measure by solving for the given variable. <br><br> Options: 125 140 35 40
Alexandra [31]

Answer:

m ∠ABD = 140°

m ∠DBC = 40°

Step-by-step explanation:

∠ (15x - 4) + ∠(5x - 8) = 180°

15x - 4 + 5x - 8 = 180

20x -1 2 = 180

20x = 180 + 12

x = 9.6

m ∠ABD = 15x - 4 = 140°

m ∠DBC = 5x - 8 = 40°
