Answer:
4.8 hours
Step-by-step explanation:
6=10$
divide by 10
0.6=1$
multiply by 8
4.8=8$
So it gives you the "= 210" part of it so you just need to figure out how to write "40% of a number is added to the number"
the questions already tells you that "the number" is "x"
so that means "40% of x is added to x"
instead of writing "add" you can replace it with a plus sign "+"
(40% of x) + x
another way to write 40% of x is 0.40x
so your equation is .4x + x = 210
Answer:
I think its the third one sorry if I got it wrong I tried my best
Answer:
x=27
Step-by-step explanation:
3x -4y =65
Let y=4
3x -4*4 =65
3x-16 = 65
Add 16 to each side
3x-16+16 = 65+16
3x = 81
Divide each side by 3
3x/3 = 81/3
x = 27
A (a,0 ) apartine Gf <=> f(a) =0
f(a) =a-2=0
a-2=0
a=2
=>
A(2,0) apartine Gf.
