Answer:

x=7

Step-by-step explanation:

Simplifying

4 + -7x + 10 = 15 + -6x + -8

Reorder the terms:

4 + 10 + -7x = 15 + -6x + -8

Combine like terms: 4 + 10 = 14

14 + -7x = 15 + -6x + -8

Reorder the terms:

14 + -7x = 15 + -8 + -6x

Combine like terms: 15 + -8 = 7

14 + -7x = 7 + -6x

Solving

14 + -7x = 7 + -6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6x' to each side of the equation.

14 + -7x + 6x = 7 + -6x + 6x

Combine like terms: -7x + 6x = -1x

14 + -1x = 7 + -6x + 6x

Combine like terms: -6x + 6x = 0

14 + -1x = 7 + 0

14 + -1x = 7

Add '-14' to each side of the equation.

14 + -14 + -1x = 7 + -14

Combine like terms: 14 + -14 = 0

0 + -1x = 7 + -14

-1x = 7 + -14

Combine like terms: 7 + -14 = -7

-1x = -7

Divide each side by '-1'.

x =7

Simplifying

x = 7

Answer:

Answer 1: <u>$6,289</u>

Answer 2: <u>$198</u>

Step-by-step explanation:

1-

a(10)=10,000(1+.05)^10

=16,288.95  =16,288-10,000=<u>$6,289</u>

2-

A(t)=pe^rt=a(10)=10,000e^(.05)(10)=16,487-10,000=6487

6487-6289=<u>$198</u>

I need help with Geometry
ehidna [41]

Answer:

We conclude that segment QR is the shortest.

Hence, option B is true.

Step-by-step explanation:

First, we need to determine the missing angle m∠R

Given the triangle Δ∠PQR

m∠P = 48°

m∠Q = 83°

m∠R = ?

We know the sum of angles of a triangle is 180°.

m∠P+m∠Q+m∠R = 180°

48°+83°+m∠R=180°

m∠R = 180° - 48° - 83°

m∠R = 49°

Thus, the value of m∠R = 49°

We know that the longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.

Here,

m∠P = 48° is the shortest angle.

As the side QR segment is opposite the smallest angle i.e. m∠P = 48°

Therefore, we conclude that segment QR is the shortest.

Hence, option B is true.
