Work:
2x+5(6x+23)=-13
2x+30x+115=-13
32x=-128
x=-4
y=6(-4)+23
y=-24+23
y=-1
The answer is (-4,-1)
Hopefully this helps!
5y + 4 = 6x-8 would be it
Answer:
see explanation
Step-by-step explanation:
the perimeter is the sum of the 3 sides of the triangle
add the parts of the ratio 21 + 8 + 14 = 43
divide the perimeter by 43 to find the value of one part of the ratio
= 5 ft ← 1 part of the ratio, hence
21 parts = 21 × 5 = 105 ft
8 parts = 8 × 5 = 40 ft
14 parts = 14 × 5 = 70 ft
the 3 sides of the triangle are 105 ft, 40 ft and 70 ft
Hello from MrBillDoesMath!
Answer: Yes, (8 1/2) /`17 = ( 17 11/12) /23
** I think you meant 11 1/2 is to 23 NOT 17 11 1/2 is to 23"
Discussion:
First, 8 1/2 = 17/2 and
(17/2
) / 17 = 1/2
Second 11 1/2 = 23/2 and
(23/2)/ 23 = 1/2
IN other words, the ratiors are the same:
8 1/2 11 1/2
------- = -------
17 23
Thank you,
MrB
