Two numbers have a difference of 12. The smaller of the two numbers is 3 less than double the other. What are the two numbers?
nexus9112 [7]

Answer:

-9,-21

Step-by-step explanation:

let the numbers be x and y and x>y

x-y=12

y=2x-3

x-(2x-3)=12

x-2x+3=12

-x=12-3

-x=9

x=-9

y=2(-9)-3=-18-3=-21

GIVING BRAINLEST FOR SIMPLE 7TH GRADE MATH PROBLEM.
mario62 [17]

Answer:

B. 60deg

Step-by-step explanation:

Both the sum of the third angle in the triangle and x has to be 180deg, as they sum to a half angle;

and the sum of angles in any triangle is 180deg.

We know that x = 180deg - (180deg - 28deg - 32deg) = 180deg - 180deg + 28deg + 32deg = 60deg

Also, note that x is drawn as smaller than a right angle. Unless the picture was made specifically to confuse us, we know that the only answer could be B.

Twice a number and 5 more is 100
8090 [49]
Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering this question today, and will be teaching you how to handle it on your own in the future.

First, let's take a look at our problem.
"Twice a number and 5 more is 100."
Based on this context, we are looking for a specific number to plug in.

To solve for this, I will rewrite the problem. As I do so, I will be writing (in parenthesis) the translation of an equation.

Twice a number (2x) and 5 more (+5) is 100 (=100).

Let's rewrite everything that's in parenthesis.
2x + 5 = 100

This is our equation.
To solve for this, we will need to do some basic algebra. Of course, I will teach you how to handle this on your own in future scenarios.

2x + 5 = 100
To solve for x, we need  to isolate 2x, and then divide both sides by 2.

2x + 5 = 100
Subtract 5 from both sides to isolate 2x.
5 - 5 = 0
100 - 5 = 95

We now have the following equation:
2x = 95
Divide both sides by 2 to solve for x.

2x / 2 = x
95 / 2 = 47.5

x = 47.5

47.5 is your number.

I hope this helps!
