During a period of extreme cold, the average daily temperature dropped decreased by 112°F day. How many days did it take for the

temperature to decrease by 9°F? Which equation would you use to find the solution?
A x + 112 = 9x + 112 = 9

B x − 112 =−9x − 112 =−9

C −112x = −9−112x = −9

D 112x = 9

It takes about 4 days for the temperature to decrease by 9°F.

An equation is an expression that shows the relationship between two or more variables or numbers.

Let x represent the number of days. Given that the temperature drop decreased by 1 1/2°F each day (- 1 1/2), for it to decrease by 9°F (-9):

-1 1/2 * x = -9

-1.5x = - 9

x = 4 days

It takes about 4 days for the temperature to decrease by 9°F.

Answer:

x = 3

Step-by-step explanation:

\\4x^2-2x=30\\\\x=3\\4(3)^2-2(3)=30\\4(9) - 6 =30\\36 - 6 = 30\\30 = 30 \\\\x=4\\4(4)^2-2(4)=30\\4(16) - 8 =30\\64 - 8 = 30\\56\neq 30

1. The perimeter of the equilateral triangle below is 75. Solve for the value
Firdavs [7]

Answer:

<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>5</u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>,</u></em>

Perimeter of a triangle = 75

One side of the triangle = 5x

<em><u>Therefore</u></em><em><u>, </u></em>

<em><u>By</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>problem</u></em><em><u>, </u></em>

5x + 5x + 5x = 75

=> 15x = 75

=> x = 75/15

=> <em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>5</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
