I'd say what you would have to do is multiply 22 by 90% which is written like this:
0.9
What you will get when you put it into the calculator will be hours.minutes
Hope this helps!!(:
Answer:
14, 21, and 63
Step-by-step explanation:
we can set the three unknown numbers as x, y, and z
so
x + y + z =98
now we are given that the first (x) is seven less than the second (y)
x = y - 7
the third number (z) is three times the second (y)
z = 3y
since we have an equation for z and x in terms of y, we can plug it into the first equation and solve for y.
(y-7) + y + (3y) =98
y - 7 + y + 3y =98
y + y + 3y =105
5y = 105
y=21
now that we know y, we can plug its value into either the second or the third equation to find x or z (I chose to find z first)
z = 3y
z = 3(21)
z = 63
now we can plug in y to find x
x = y - 7
x = 21 - 7
x = 14
so the three numbers should be 14, 21, and 63
Answer: The answer is -1/8
Step-by-step explanation:
3/4*2/3+3/4*-5/6
3 is cancelled out with 3, 4 with 2, 3 with 6
1/2-5/8
take the L.C.M
4(1)-1(5)/8
4-5/8
=-1/8
