Bobby wants to go on a school trip that will cost him $250. He comes up with an equation that represents how much he needs to sa

monitta

Yes, Bobby will have enough money if he saves for 9 weeks. You can find this through either substituting w for 9 in the equation, or solving the equation itself.

Substituting:

$25(9)+30$
Substitute w for 9.

$225+30$
Simplify.

$225+30=255$
Solve.

255 is greater than 250, so yes, he will have enough money saved.

Solving the equation:

$25w+30=250$
Original Equation

$25w=220$
Subtract 30 from both sides.

$w=8.8$
Divide both sides by 25.

The number of weeks he needs is 8.8. When rounding it up, you get 9.

kozerog [31]

Answer:

58.75 degreeF

Step-by-step explanation:

The initial temperature of the Soda = 40degreeF

The temperature outside is steady at 99 degreeF

The temperature of the soda became 50 degreeF after 8 minutes

In 8 minutes, the Soda gained

(50 - 40)degreeF

= 10 degreeF

If the soda gains 10 degreeF in 8 minutes, in 1 minute, it will gain 10/8degreeF

Therefore in 7 minutes, the soda will gain (10/8)*7

= 70/8

= 8.75 degreeF

The expected temperature of soda after an additional 7 minutes = 50 + 8.75

= 58.75degreeF

Ivenika [448]

Answer:

667 bagels in 23 hours

29 bagels per hour

Step-by-step explanation:

We first find the unit rate in bagels per hour.

(290 bagels) / (10 hours) = 29 bagels/hour

Now we find the number of bagels made in 23 hours.

23 hours * 29 bagels/hour = 667 bagels
