Answer:
-0.8x + 4.8y + 16
Step-by-step explanation:
4(0.5x+2.5y-0.7x-1.3y+4) = 4( 0.5x - 0.7x + 2.5y - 1.3y + 4)
= 4( -0.2x + 1.2y + 4)
= 4*(-0.2x) + 4 *1.2y + 4*4
= -0.8x + 4.8y + 16
Divide 132 by 16 to get 8.25 and you have to round up because you can’t fit 0.25 of people on a table.
Answer:
The third sentence is wrong.
Step-by-step explanation:
It is not 2 divided by a number equals 14. 7 is divided by a number and equals 14.
3x=14-5
3x=14-5
3x=9
x=9 ➗ 3
x= 3
the answer is 3
In order to solve this equation you must eliminate one of the variables.
By multiplying by -3 you eliminate the y variable, making A the correct answer.
-6x-3y=-66
5x+3y=29
-x=-37
x=37
