The larger of two consecutive integers is 10 more than 4 times the smaller. Find the integers.
nevsk [136]

Answer:

-2 and -3

Step-by-step explanation:

Let L represent the large integer and S represent the smaller integer

Given  Large Integer = 10 + 4 times Smaller Integer

Mathematically:

L = 10 + 4S -------eq 1

It is also given that the integers are consecutive,

hence L = S + 1------ eq2

Now we can solve a system of equations by substitution.

Substitute eq 2 into eq 1

S + 1 = 10 + 4S    (subtract 1 from both sides)

S = 10 - 1 + 4S

S = 9 + 4S  (subtract 4S from both sides)

S - 4S = 9

-3S = 9 (divide both sides by -3)

S = 9 / (-3) = -3  (answer)

form equation 2,

L = S + 1

L = -3 + 1

L = -2 (answer)

Solve for x in the diagram below.<br> 100°<br> 20<br> 2=
ad-work [718]

Answer:

x = 40

Step-by-step explanation:

The answer is x = 40. This is because the two angles that are x are 1. congruent and 2. supplementary with 100° (They all add up to 180°). I can show this with a simple equation.

1. 2x + 100 = 180

2. 2x = 80

3. x = 40

Hope this helps! (Please consider giving brainliest)
