Step 1: Find the slope of the line. To find the slope of the given line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 3x – 5y = 9 is m = 3<span>/5. Therefore, the slope of the line parallel to this line would have to be </span>m = 3<span>/5.</span>
Answer: She can buy 6 shirts
Step-by-step explanation: You subtract 95 from 240, which gives you 145 so you do 145/22.5 which will give you 6.4444 but you can't buy .44 of a shirt so you round down and you get 6.
Answer: option c is the correct answer.
Step-by-step explanation:
The given system of equations is expressed as
5x + 2y = - 38 - - - - - - - - - - -1
6x + 10y = - 19 - - - - - - - - - - - 2
We would eliminate x by multiplying equation 1 by 6 and equation 2 by 5. It becomes
30x + 12y = - 228
30x + 50y = - 95
Subtracting, it becomes
- 38y = - 133
Dividing the left hand side and the right hand side of the equation by - 38, it becomes
y = - 133/-38 = 3.5
Substituting y = 3.5 into equation 1, it becomes
5x + 2 × 3.5 = - 38
5x + 7 = - 38
5x = - 38 - 7 = - 45
Dividing the left hand side and the right hand side of the equation by 5, it becomes
x = - 45/5 = - 9
To solve for X: First you multiply x and 6 then subtract 21 on both sides and then divide by 6
531 = ( X × 6) + 21
531 = 6X + 21
510 = 6X
85 = X
Hope this helps :)
Answer:
25^2=625
24^2= 576
7^2= 49
as 625 = 576+49 so 7,24,25 form a Pythagorean triplet
similarly
9,40,41 also is a Pythagorean triplet
