Answer:
Step-by-step explanation:
The system of linear equations that Beatrice wanted to solve by the method of elimination is expressed as
4x − 3y = 9 - - - - - - - - -1
3x + 2y = 11 - - - - - - - - - - 2
In order to eliminate the x- terms, Beatrice could multiply the first equation by 3 and the second equation by - 4 and add the first equation to the second equation. This would make the x terms to be equal. The x terms in the first and second equations becomes 12x and - 12x
The range of shelter A is 22. The range of shelter B is 18.
<h3>What are the measures of spread?
</h3>
A box plot is used to study the distribution and level of a set of scores. The box plot consists of two lines and a box. the two lines are known as whiskers. The end of the first line represents the minimum number and the end of the second line represents the maximum number. The range is the difference between the two numbers.
- Range of shelter A = 30 - 8 = 22
- Range of shelter B = 28 - 10 = 18

10(3x+2)>7(2x-4)
Use the distributive property:
30x + 20 > 14x -28
Subtract 14x from both sides:
16x + 20 > -28
Subtract 20 from both sides:
16x > -48
Divide both sides by 16:
x > -3
The inequality is X > -3
Answer:-2 1/2
Step-by-step explanation
-2-8=-10
7-11=-4
which gives you -10/-4 which simplifies to -2 1/2
