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:
Slope, m = 5
Step-by-step explanation:
Picking points on the x-axis and y-axis of the graph;
Point on x-axis (x1, x2) = 2, 4
Points on the y-axis (y1, y2) = 10, 20
To find the slope;
Mathematically, slope is given by the formula;
Substituting into the equation, we have;
Slope, m = 5
Ok,
f(0.35)= 7f/20
f(-5.2)=-26f/5
f(10)= 10f
f(-0.5)= -f/2
as for the last question I am not quite sure, sorry....hope I helped a little :)
Answer: 15/16
there are 15 scenarios in which you get at least 1 head and one where you don't therefore the answer is 15/16
The answer is b=8!! hope this help
