so
xyz

x+y+z=12
3x-2y=5
6z+4y=50
so multiply 3x-2y=5 by 2
6x-4y=10
add to 6z+4y=50 and get
6x+6z+4y-4y=10+50
6x+6z=60
distribute
6(x+z)=6(10)
divide both sides by 6
x+z=10
subsitute 10 for x+z in the first equation
10+y=12
y=2
subsitute
3x-2(2)=5
3x-4=5
3x=9
x=3

x+z=10
3+z=10
z=7



x=3
y=2
z=7

65% of 80 is what number

Answers

Answer:

52

Step-by-step explanation:

We can find the percent of  a number by converting the percent to a decimal.

65%=0.65

80(0.65)=52

To find 65% of 80, first write 65% as a decimal by moving the decimal point 2 places to the left and we will get .65. Next, the word "of" means multiply, so we have (.65) (80) = 52.

Therefore, 65% of 80 is 52.
