MODELING WITH MATHEMATICS Write and solve an equation to determine how many degrees the temperature $T$T fell. The temperature at 5 P. M. is $20\degree$20° F. The temperature at 10 P. M. is $-5\degree$−5° F.

Equation: $=-5$=−5

The temperature fell 25degree$\degree$° F.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

you already gave the answer

step-by-step explanation:

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
