Xy is the number
A) x + y = 7
B) 10y + x = 10x + y + 9
collecting terms of equation B
B) -9x + 9y = 9
multiplying A) by 9
A) 9x + 9y = 63 then adding it to equation B)
B) -9x + 9y = 9
18y = 72
y = 4
x = 3
The number is 34
Answer:
B 7feet
Step-by-step explanation:
Side a = 24
Side b = 25
Side c = 7
Angle ∠A = 73.74° = 73°44'23" = 1.287 rad
Angle ∠B = 90° = 1.5708 rad = π/2
Angle ∠C = 16.26° = 16°15'37" = 0.28379 rad
C=16.26°B=90°A=73.74°b=25a=24c=7
Area = 84
Perimeter p = 56
Semiperimeter s = 28
Height ha = 7
Height hb = 6.72
Height hc = 24
100 x .4 = 40
40 x 12 = 480
The bank account would have $480 over 12 years. Hope this helps and please mark brainliest
