To solve this question we must first find out what is x.

X + x - 4 = 82 degrees

2x - 4 = 82

2x = 86

X = 86/2 = 43.

Here x would be 43 degrees.

We can add up the angles because we know the angle of DAC and the CAB angle add up to give 82 degrees.

Which of the options represents the resulting equation after an equivalent expression for y is substituted into the second equat

Nina [5.8K]

Answer:

Correct choice is D

Step-by-step explanation:

Given the system of two equations:

$\left\{\begin{array}{l}4x+y=8\\6x-9y=12\end{array}\right..$

Fro mthe first equation

$y=8-4x.$

Substitute into the second equation $8-4x$ instead of y:

$6x-9(8-4x)=12.$

Note that $8-4x=-4x+8,$ then the second equation will take look

$6x-9(-4x+8)=12.$

Answer:

similar; RYL by SAS similarity

Step-by-step explanation:

Side RL Is congruent to side RH and side RY is congruent to side RA by a scale factor of 3.5. and we know thank angles LRY and HRA are congruent by the reflexive property. So the two triangles are congruent by Side-Angle-Side similarity.

You have the numbers 1-24 written on slips of paper. If you choose one slip at random, what is the probability that you will not

The probability of selecting a number not divisible by 3 is: 2/3

Step-by-step explanation:

There are two methods to solve the question.

We can find the probability of numbers not divisible by 3
We can find the probability of numbers divisible by 3 and then find the complement of it

We will use the second method:

Given:

There are 24 slips

S = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24}

n(S) = 24

Let A be the event that the slip number is divisible by 3

Then

A = {3,6,9,12,15,18,21,24}

n(A) = 8

The probability of number divisible by 3 is:

$P(A) = \frac{n(A)}{n(S)}\\=\frac{8}{24}\\=\frac{1}{3}$

The sum of the probability of an event's occurrence and non-occurrence is 1. So the probability of numbers divisible by 3 will be subtracted from 1 to find the probability of selecting a number not divisible by 3.

The probability of selecting a number not divisible by 3 will be:

$=1-\frac{1}{3}\\=\frac{3-1}{3}\\=\frac{2}{3}$

The probability of selecting a number not divisible by 3 is: 2/3

What is the solution to the equation below log5(2x-3)=2

Komok [63]

Answer:

Step-by-step explanation:

Use the exponential form of this log equation. Rewriting this into exponential form gives us

$5^2=2x-3$

5-squared is 25, so

25 = 2x - 3 and

22 = 2x so

x = 11
