Answer:

T^\circ  = -12^\circ

Step-by-step explanation:

Given

Represent the temperature in Tucson with T and that in Minneapolis with M.

From the first statement, we have:

T^\circ = M^\circ - 24^\circ

From the second, we have:

T^\circ = -M^\circ or M^\circ = -T^\circ --- i.e. both are opposite numbers

Required

Find T

To calculate T, substitute -T for M in T^\circ = M^\circ - 24^\circ

This gives:

T^\circ = -T^\circ - 24^\circ

Collect Like Terms

T^\circ +T^\circ =- 24^\circ

2T^\circ  =- 24^\circ

Make T the subject

T^\circ  =- 24^\circ/2

T^\circ  = -12^\circ

Hence, the temperature in Tucson is -12^\circ

lutik1710 [3]

Answer:

A) 7x^2-7x+15

Step-by-step explanation:

f(x) = 4x2 - 5x + 7,

g(x) = 3x2 - 2x + 8

f(x) +g(x) =

4x^2 - 5x + 7 + 3x^2 - 2x + 8=

7x^2-7x+15

Solve for x and write your answer in simplest form.<br><br> -1/2 -1/2(4/5x+1) = -2 -3x
dimaraw [331]

The solution of the equation which is as described in the task content when expressed in its simplest form is; -5/13.

<h3>What is the solution of the equation as described in the task content?</h3>

It follows from the task content that the solution to the equation is to be determined and expressed in its simplest form.

Given;

-1/2 -1/2(4/5x+1) = -2 -3x

By distributing the coefficients: we have;

-1/2 - 2/5x - 1/2 = -2 -3x

Hence, by collecting like terms; we have;

-1/2 - 1/2 + 2 = -3x + (2/5)x

1 = -13x/5

Therefore; by cross-multiplication; we have;

5 = -13x

Divide both sides by; -13.

x = -5/13.

Ultimately, the solution of the equation which is as described in the task content when expressed in its simplest form is; -5/13.
