3. Carl earned 8 x + 7 dollars this week mowing yards while Patrick earned -3 x + 18 dollars
walking dogs. Which of the following shows
how much the boys earned all together and
also how much more Carl earned this week
than Patrick earned?
5 x + 25 and 11 x + 25
5x + 25 and 11 x-11
5x + 11 and 5 x + 25
5 x + 25 and 5 x-11

Step-by-step explanation:

5 x + 25 and 11 x + 25

5x + 25 and 11 x-11

5x + 11 and 5 x + 25

5 x + 25 and 5 x-11 this all equal to 5,900 dived by 5

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
