<span>the tens digit = n
</span><span>the units digit = n-5
n + n-5 = 9
2n = 9+5
2n = 14
n = 7 </span>← the tens digit
the units digit = n-5 = 7 - 5 = 2
<span>the number is 72</span>
we have that
*-------------------------*--------------------------------*
E F G
EF=2x-12
FG= 3x-15
EG=23
we know that
EF + FG = EG
so
[2x - 12] + [3x - 15] = 23 simplify
5x - 27 = 23 add 27 to both sides
5x = 50 divide both sides by 5
x = 10
EF=2x-12-------> EF=2*10-12-------> EF=8
FG= 3x-15------> FG=3*10-15------> FG=15
therefore
the answer part a) is
the value of x is 10
the answer part b) is
the value of EF is 8
the answer part c) is
the value of FG is 15
Answer:
The inverse of this equation would be y = 
Step-by-step explanation:
To find the inverse of any equation, start by switching the y and x values. Then solve for the new y value. That equation will be your inverse.
y = 7x^2 - 3
x = 7y^2 - 3
x + 3 = 7y^2
= y^2
= y
Answer:
24 ft^2
Step-by-step explanation:
Area of a triangle
A = 1/2 b*h
We know the base is 8 ft and the height is 6 ft
A = 1/2 (8) (6)
= 1/2 (48)
= 24 ft^2
