vazorg [7]

Answer:

x - 18°F = 2°F

x = 20°F

Step-by-step explanation:

First, write the equation with the information you know. It dropped 18°F from 6 to midnight, and by midnight the temperature was 2°F

Your equation should look like this: x - 18°F = 2°F

Move the constant to the right hand side and change it's sign:

x = 2°F + 18°F

Add the numbers to get x = 20°F

Hope this helped!

Goshia [24]
<h3><u>An inequality to show how much he might spend on souvenirs and snacks is:</u></h3>

x\leq 13.5

<h3><u>Solution:</u></h3>

Given that,

Gabe went to the amusement park with $40 to spend

His ticket cost $26.50

Therefore,

Total amount she has = $ 40

Ticket cost = $ 26.50

Let "x" be the amount he might spend on souvenirs and snacks

Therefore,

Remaining amount = 40 - 26.50

Remaining amount = 13.5

Thus she can spend less than or equal to $ 13.5 on souvenirs and snacks

Which is represented in inequality as:

x\leq 13.5

Thus the inequality is found
