Answer:
x=7
Step-by-step explanation:
95+65=160
There is 360 degrees total in a quadrilateral
360-160=200
(15x-5)+100=200
15x+95=200
Subtract 95 from both sides
15x=105
x=7
Answer:
(-3, -5), because the point satisfies both equations.
Answer:
y=17/2 and x=15/8
Step-by-step explanation:
By subsitution, we get 4x+4x+1=16, so 8x=15. Thus, x=15/8. Next, we plug x in to find y. y=4*15/8 +1, or 15/2 +1 = 17/2
Answer:
(a;b)={(17; 64); (64; 17)}
Step-by-step explanation:
a+b=81 => b=81-a
a*b=1088
a*(81-a)=1088
-a²+81a=1088
a²-81a+1088=0
a²-64a-17a+1088=0
a(a-64)-17(a-64)=0
(a-17)(a-64)=0
=> a=17 and a=64
for a=17 => b=81-17=64
for a=64 => b=81-64=17
(a;b)={(17; 64); (64; 17)}
